abstract = "In a greater study of the recent fossil Gadidae, the
object of this paper is to better define the
trisopterine species and their relationships. The
taxonomy of the four recent species usually included in
the genus Trisopterus is further elaborated by means of
published and new data on their otoliths, by published
data on general external features and meristics of the
fishes, and their genetics. Fossil otoliths, from the
beginning of the Oligocene up to the present, reveal
much of their evolution and throw more light on their
relationships. Several succeeding and partly
overlapping lineages representing different genera are
recognized during this time interval. The genus
Neocolliolus Gaemers, 1976, for \bioname{Trisopterus
esmarkii} (Nilsson, 1855), is more firmly based. A new
genus, Allotrisopterus, is introduced for
\bioname{Trisopterus minutus} (Linnaeus, 1758). The
similarity with \bioname{Trisopterus capelanus}
(Lacep{\`e}de, 1800) is an example of convergent
evolution. The tribe Trisopterini Endo (2002) should
only contain Trisopterus, Allotrisopterus and
Neocolliolus as recent genera. Correct identification
of otoliths from fisheries research and from sea bottom
samples extends the knowledge of the present day
geographical distribution of T. capelanus and T. luscus
(Linnaeus, 1758). T. capelanus is also living along the
Atlantic coast of Portugal and at least up to and
including the R{\'\i}a de Arosa, Galicia, Spain. There
it can easily be mistaken for A. minutus that is also
living there. Otoliths of T. luscus have been
identified from the Evvo{\"\i}k{\'o}s Channel between
Euboia and the mainland of Greece, thus it must live
also in the Aegean Sea. Otoliths prove to be a powerful
tool in taxonomy, biogeography and evolution of
teleosts.",

performed using three different experimental diets with
increasing carbohydrate levels based on potato starch

energy: 16\% S (16\% S--44\% P), 22\% S (22\% S--40\%
P) and 28\% S (28\% S--36\% P). Tropical gar larvae
(five days post-hatching, 2.1 mm average notochordal
length) were assessed for growth, survival, degree of
cannibalism, and digestive enzyme activities for 30
days. Highest growth and survival (24\%), as well as
the lowest cannibalism (33\%), was seen in larvae fed
the 28\% S diet, and these larvae also had the highest
lipase, amylase and glucosidase activities (0.28, 0.56

(alkaline protease, trypsin, chymotrypsin, and leucine

In conclusion, dietary inclusion of potato starch at

We found that catfish performances were mainly

protein:lipid ratios in the diets made of plant
ingredients were high but SGR was low. Specific growth
rate (SGR) increased with the increase of feed FM
content, being ca. 5\% day\minus 1 with 60\% FM diet

of 30\% BNM or SBM inclusion with 30\% FM. Feed
conversion ratio increased from below 0.6 of the 60\%
FM diet up to 1.5 (60\% SBM) and 1.7 (60\% BNM).
Protein efficiency ratio decreased linearly with
increasing FM substitution, but protein productive
value (PPV) was similar for catfish fed 60\% FM diet

results suggest that protein:lipid ratio cannot be used

significantly declined during the initial periods of U.
mutica reinvasion, but did not decline further after
the grass became established. No differences in the M.

that M. engeli are habitat generalists. These findings
are among the first in an insular tropical estuary
demonstrating a negative relationship between an
invasive grass and relative abundances of two
confamiliar fish, while revealing distinct patterns
attributed to species-specific traits. Importantly, the
broad overlapping biogeographic distribution of M.

hypothesized that B. belizanus distribution in Tampa

for aquaculture diversification in the Persian Gulf and

received considerable attention, and nutritional
studies focused on establishing the nutritional
requirements for improving diet formulation have been
conducted during recent years. Considering the results
from different dose--response nutritional studies on
macronutrient requirements conducted in this species,
it can be concluded that diets containing ca. 48\%
crude protein, 15\% crude lipid, 15\% carbohydrates and
20 KJ g \minus 1 gross energy are recommended for
on-growing S. hasta juveniles. In addition, the optimum
essential amino acid profile for this species
(expressed as g 16 g N \minus 1), should be
approximately arginine 5.3, lysine 6.0, threonine 5.2,
histidine 2.5, isoleucine 4.6, leucine 5.4, methionine
+ cysteine 4.0 (in a diet containing 0.6 cysteine),
phenylalanine + tyrosine 5.6 (in a diet containing 1.9
tyrosine), tryptophan 1.0 and valine 4.6. Moreover, the
optimum dietary n-3 long chain polyunsaturated fatty
acids and soybean lecithin are recommended to be 0.8\%
and 6\%, respectively. The maximum replacement of fish
meal with soy protein is recommended to be between
16.5\% and 27.3\%. In addition, different vegetal oil
sources are also recommended for partial and almost
complete replacement of fish oil in diets. Although the
nutritional requirements in terms of macronutrients
have been established under laboratory conditions, the
analysis of the available literature indicate that
future studies need to be conducted using a more
holistic approach under intensive farming conditions in
which different nutrients or additives need to be

marine conditions, in an effort to maximize recruitment
success. This reproductive strategy, however, is
accompanied by a trade-off between reproductive effort

experimental immune challenge in adult animals, with
the goal of establishing this genetically-tractable

available genomic databases, zebrafish AMP sequences
homologous to AMPs from other vertebrates were selected
for further study. These included parasin I and its
enzyme cathepsin D, \beta -defensin (DB1),
liver-expressed antimicrobial peptide 2 (LEAP2),
bactericidal permeability-increasing protein (BPI), and
chromogranin-A and -B (CgA and CgB). Specific primers
were designed for RT-PCR amplification of each AMP gene
of interest and amplicons between 242 bp and 504 bp
were obtained from RNA extracted from adult zebrafish.
Sequencing of the amplicons and alignment of their
deduced amino acid sequences with those from AMPs from
other vertebrate species confirmed their identity. The
temporal expression of AMPs was investigated by RT-PCR
analysis in fertilized oocytes, embryos, and adult
individuals. Parasin I and chatepsin D transcripts were
detectable immediately after fertilization, while the
transcripts for CgA and CgB became evident starting at
48 h post fertilization. Mature transcripts of LEAP2
and DB1 were detectable only in the adult zebrafish,
while BPI transcripts were detectable starting from the
12th day post fertilization. To explore the possible
upregulation of AMP expression by infectious challenge,
experiments were carried out in adult zebrafish by
intraperitoneal injection of a cocktail of
lipopolysaccharide and lipoteichoic acid. Except for
CgA and CgB, amplicons corresponding to all tested AMPs

abstract = "The management of highly migratory species (HMS) is a
complex domestic and international system that was
initially established to regulate HMS taken in
commercial fisheries in the Atlantic Ocean. For
managing HMS taken in recreational fisheries, the
authority and the data required is lacking and remains
to be stipulated by regulating bodies. In the {United
States}, Florida saltwater anglers target various HMS,
but swordfish (\bioname{Xiphias gladius}) is a favorite
among anglers. The recreational swordfish fishery off
the Southeast Florida coast has experienced resurgence
in recent years, with directed tournaments resuming in
2001 after being absent almost 20 years. Today, South
Florida supports the largest group of recreational
swordfish anglers in the world. Despite the increasing
popularity and interest, little data is available
describing the recreational swordfish fishery and its
socio-economic aspects in South Florida. This study
aimed to compile, describe, and identify the
demographics, fishing tactics, costs, and fishery
management perceptions of recreational swordfish
anglers in South Florida based on nonprobability
purposive sampling organized through the Southeast
Swordfish Club (SESC). The sample size (n = 38)
represented about 16--38\% of the SESC members and
between 6\% and 8\% of the recreational anglers that
actively targeted swordfish in South Florida during the
time of the survey. We acknowledge the sample size was
small (n = 38), but believe the study encompassed the
most active swordfish anglers given their knowledge,
expertise, and connection with the fishery in terms of
participants, fishing effort, and fishing techniques.
As such, it is highly probable that a large portion of
the recreational swordfish angling population was
represented by members of the SESC in terms of
swordfishing gear, techniques, and socio-economics,
which reduced apparent bias in the study. Overall, the
annual income of recreational swordfish anglers in 2007
ranged from US \$15,000 to \$200,000 with an average
income of \$91,940 ($ n = 33$). Sixty-nine percent of
polled anglers indicated they had more than 26 years of
recreational fishing experience and 81\% had less than
10 years of experience targeting swordfish in South
Florida. Thirty-seven percent of surveyed anglers
indicated they departed from Port Everglades, Florida.
To target swordfish, anglers generally used five rods
and set their bait, commonly squid, at 91 m. Anglers
also indicated they changed their fishing tactics from
day to night, and took about five fishing trips per
month. Overall, anglers spent around \$14,210 on annual
costs associated with swordfishing, which was 16\% of
their annual income. Many polled anglers also reported
they were dissatisfied with the current swordfish
management regulations.",

the native Pomatoschistus sp. (goby) and the NIS

the most abundant taxa in the majority of salt marsh
habitats, except for one specific, marsh pool, where
extreme environmental conditions were registered,
namely high temperature and salinity. Such conditions
may have boosted the intrusion of mummichog in this
area. This species is well adapted to a wide range of
abiotic factors enabling them to colonize habitats
where no predators inhabit. Impacts of mummichog
introduction in the Guadiana salt marsh area are still
unpredictable since this is the first time they have
been recorded in such high density. Nevertheless, in
scenarios of increased anthropogenic pressure and,
consequently, habitat degradation, there is a potential
risk of mummichog spreading to other habitats and
therefore competing for space and food resources with

structural characteristics of fish skin still remain
not clearly understood. That is the case with scales,
which have always been attributed a mere protective
role, but which are proving to have more functions than
it was traditionally thought. To acquire a deeper
knowledge, scales from six different regions of
gilthead seabream (\bioname{Sparus aurata} {L.}) were
studied and measured by image analysis. Results prove
that scales from the base of the dorsal fin are larger
than those in other parts of the fish body while scales
from the peduncle are the smallest of the skin.
Furthermore, a technique relatively new in this field,
known as atomic force microscopy (AFM), was used to
obtain representations of the ultrastructure of the
scales and measure certain features such as the circuli
and the lines in the basal layer. The data obtained
allowed us to compare the height of circuli among the
different scales, showing that they were higher in
scales from the dorsum and the operculum. The present
results introduce a nanostructural model of the scales
of gilthead seabream that might serve as a useful
guideline for future studies.",

MON at the concentration tested (450 $ \mu $ g L \minus

decrease in the standard length of exposed specimens at
20 days post fertilization. Survival decreased
significantly in larvae exposed to MON concentrations
higher than 900 \mu g L \minus 1. Influence of MON on
survival and growth might be relevant for aquaculture
industry. As MON is a water-soluble mycotoxin, its
leaching from feed is highly probable, so MON
assimilation into the surrounding aqueous environment
should also be considered. Tested levels in fish larvae
are within the reported occurrence levels of MON in

mudflats is practiced for recreational and commercial
purposes in European coastal systems including the Ria
de Aveiro coastal lagoon on the northwest Atlantic
coast of Portugal. The scale of harvesting in the Ria
de Aveiro has recently increased due to the current
economic climate in Portugal, with targeting of the
polychaete, \bioname{Diopatra neapolitana} species or
``casulo'' as it is widely known in the Aveiro region.
The national authorities have attempted to control
casulo digging by issuing a regulation (Ordinance) in
2014 on the maximum daily catch limit to be caught by
each individual. The daily catch limit is intended to
represent the Maximum Sustainable Yield (MSY) for
casulo beyond which overfishing will occur. The
monitoring of the regulatory measures is expected to be
conducted through on-site inspections in the digging
areas. However, weak law enforcement was noticed, while
there is also controversy over the daily catch limit
(quota) stipulated by the Ordinance. To this end, the
current study attempted to assess digging activities
through remote monitoring and random inspections for a
better policy enforcement of the national regulation.
In addition, different harvesting scenarios were
employed through a simplified bioeconomic model to
attribute the current and future harvesting trends of
bait digging in Aveiro coastal lagoon. The study
findings indicate that remote monitoring coupled with
some onsite interviews could be a more effective
approach for the implementation of the current bait
digging policy. Further, the results point to a
distinctive discrepancy between the daily catch amount
(MSY) introduced by the national legislation and the
study findings which should be further scrutinized. The
diggers seem to have reached the sustainable harvest
identified by the present research. The current
economic hardship in Portugal and the low profitability
in similar employment sectors will possibly attract
more diggers and increase harvesting in the near
future. An increased harvest would likely trigger
overfishing of D. neapolitana with unknown consequences
for the population of the species as well as the
aquatic ecosystem. The socio-economic and environmental
effects are yet to be further clarified with more
detailed data and advanced modeling techniques to
ensure the sustainability of the activity.",

Parasites with a male copulatory organ were more likely
to abandon the host and attempt a host transfer.
Additionally, in vivo video observation suggested that
detached worms employ water turbulence to assist their

changed substantially along the Eastern Mediterranean
continental shelf, which is a hotspot of invasion by
species that had migrated via the Suez Canal. Trawl
data from the Israeli coast spanning two periods
(1990--1994 and 2008--2011) were compared to identify
species with substantial variation in their relative
abundance between the two periods. The aim of this
study was to examine if certain ecological traits
characterize fish species showing an increase or
decrease in relative abundance, and if non-indigenous
fishes with strongly increasing populations may have
caused the decline of native species with similar
habitats and diets. We found that the main predictors
of population trends were species length, habitat
affinity, and maximum depth, with larger and soft
bottom species displaying decreasing abundances.
Comparing native and non-indigenous fishes with similar
habitat and diet, we found a potential for competitive
impact of the Indo-Pacific \bioname{Plotosus lineatus}
and two Upeneus spp. on the native Mullus species.
However, competition with non-indigenous fishes could
not generally explain the dramatic decline of many
other native species between the two study periods.
Alternative causes, such as fishery pressure and
increasing water temperature, are discussed.",

of GnRHa-delivery systems resulted in multiple spawns

catsharks returned to water for recovery. Muscle
lactate and water content were quantified after acute
exposure (for 18 min), 5 h and 24 h. This challenge
elicited stress responses in the muscle such as
increased lactate levels and immediate dehydration,
followed by recovery of lactate levels and
overhydration. Muscle consistency, a relevant variable
describing quality of seafood according to its ability
to be swallowed by the consumer, paralleled muscle
water content changes. The results indicated for the
first time that handling alive sharks exposed to air
results in muscle fillets with different texture
properties. Whether these changes in muscle texture
induce higher quality fillets has yet to be proven. Our
recommendation is to minimize time of air exposure

Because S. japonicus has a much higher market price

makes discrimination difficult. These species can be
effectively distinguished using the ratio of the base
length between the dorsal fin's first and ninth spines
to the fork length. However, manual measurement of this
ratio is time-consuming and reduces fish freshness. The
proposed technique instead uses image processing to
measure these lengths. We were able to successfully
discriminate between the two species using the ratio as

salt solution for 10 min) drying methods. The results
showed that the dried fish produced by the solar tunnel
drying method were rehydrated more rapidly than the
products produced by the traditional and improved
drying methods. The moisture content of the dried H.
molitrix was varied from 18.24 to 25.43\% on a fresh
matter basis. There was no significant (p $>$ 0.05)
difference found regarding the protein, lipid, and ash
content among the different drying methods on a dry
matter basis. The total volatile base nitrogen (TVB-N)
contents ranged between 37.58 and 45.03 mg/100 g, and
significantly (p {$<$} 0.05) the lowest TVB-N was
observed in dried fish produced by the solar tunnel
drying method. Moreover, the highest peroxide and acid
values were found in the traditionally produced dried
fish as compared with the fish dried by the improved
and solar tunnel drying methods. The aerobic plate
count of dried fish ranged from 4.52 to 7.51 log CFU/g.
The sensory evaluation results revealed that the
solar-dried products showed superior quality than the
products produced by the traditional and improved
drying methods. The results revealed that the dried
fish produced by the solar tunnel drying method
provided the best product in terms of physico-chemical,
microbiological, and sensory aspects.",

available resources between fitness-relevant
physiological functions. Organisms possess phenotypic
plasticity to acclimate to changing environmental
conditions. However, this comes at a cost that can
cause negative correlations or ``trade-offs'', whereby
increasing investments in one function lead to
decreased investments in another function. The aim of
the present study was to investigate the prioritization
of resource allocation between growth, pathogen
defense, and contaminant response in juvenile rainbow
trout (\bioname{Oncorhynchus mykiss}) exposed to
changes of resource income or expenditure. We performed
a multifactorial experiment with three
resource-impacting stressors --- limited food
availability, a parasitic infection, exposure to a
vitellogenesis-inducing contaminant --- and
combinations thereof. Treatment with the individual
stressors evoked the expected responses in the
respective physiological target systems --- body
growth, immune system, and hepatic vitellogenin
transcription --- but we found little evidence for
significant negative relations (trade-offs) between the
three systems. This also applied to fish exposed to
combinations of the stressors. This high phenotypic
flexibility of trout in their resource allocation
suggests that linear resource allocations as mechanisms
of phenotypic plasticity may be too simplistic, but it
also may point to a greater capacity of ectothermic
than endothermic vertebrates to maintain key
physiological processes under competing resource needs
due to lower maintenance costs.",

naturally spend the first years of life in brackish

show that juveniles may not successfully face either
freshwater or hyper-osmotic environments as high as 55

Furthermore, we found that osmoregulatory tissues such
as gills managed to maintain plasma osmolality levels
without differences in meagre acclimated at 5, 12 and
39 ppt salinity. Our results demonstrate the euryhaline
capacity of this species, highlighting that juveniles
may be cultured in a wider range of salinities rather

aquaculture and fisheries for decades as it represents
an important life history trait and is critical for
captive propagation and successful recruitment. A major
factor influencing egg quality is proper yolk
formation, as most fishes are oviparous and the
developing offspring are entirely dependent on stored
egg yolk for nutritional sustenance. These maternally
derived nutrients consist of proteins, carbohydrates,
lipids, vitamins, minerals, and ions that are
transported from the liver to the ovary by lipoprotein
particles including vitellogenins. The yolk composition
may be influenced by broodstock diet, husbandry, and
other intrinsic and extrinsic conditions. In addition,
a number of other maternal factors that may influence
egg quality also are stored in eggs, such as gene
transcripts, that direct early embryonic development.
Dysfunctional regulation of gene or protein expression
may lead to poor quality eggs and failure to thrive
within hours of fertilization. These gene transcripts
may provide important markers as their expression
levels may be used to screen broodstock for potential
spawning success. In addition to such intrinsic
factors, stress may lead to ovarian atresia or
reproductive failure and can impact fish behavior,
fecundity, and ovulation rate. Finally, postovulatory
aging may occur when eggs become overripe and the fish
fails to spawn in a timely fashion, leading to low
fertility, often encountered during manual strip
spawning of fish.",

collected from both producers and retailers from
December 2016 to April 2017. A control sample was also
prepared in the laboratory with the same raw fish used
by the producers to compare the results. Gas
chromatography with electron capture detector (GC-ECD)
was used to detect and quantify OCP residues. Six
samples out of 27 (about 22\%) were found to be
contaminated with OCP residues. Among these six
adulterated samples, four were from retailers and two
from producers. Only aldrin was detected in four
samples, and in the other two samples both aldrin +
dieldrin and aldrin + endrin were detected. Aldrin was
found in quantities between 0.332 and 0.967 ppm,
dieldrin 0.762 ppm, and endrin 0.828 ppm. All these
values were much higher than the maximum residual limit
(MRL) of 0.1 ppm. Total plate count (TPC) of producer
samples ranged from 5.3 {\pm} 0.02 log cfu g {-1} to

begun in the fall and post-vitellogenic oocytes of 1250

in spermiation condition and produced good-quality
sperm throughout the year, regardless of the
temperature profile to which they were exposed. Some
females completed oogenesis, underwent oocyte
maturation, and spawned spontaneously under both
constant and fluctuating temperatures. The sex steroid
hormones of both males and females followed the
already-known profiles during fish gametogenesis,
except for 17,20{\beta}-dihydroxy-progesterone, which
did not seem to be related to either female or male
maturation. The female reproductive dysfunctions that
were identified included (a) the arrest of oogenesis at
the cortical alveoli stage in certain females; (b) the
failure to undergo oocyte maturation in others; and (c)
the production of large percentages of unfertilized
eggs from the females that spawned spontaneously. Our
study suggests that reproduction in captivity is
possible in wreckfish maintained under typical marine
aquaculture conditions, but that reliable spawning and
production of high-quality eggs may require some years
of adaptation to captivity, before the reproductive

abstract = "This study investigated whether compensatory growth
causes long-term effects in relative brain- or
intestine size in a wild, predominantly anadromous,
population of brown trout (\bioname{Salmo trutta}). The
subject fish belonged to two treatment groups; one
group had undergone starvation and subsequent growth
compensation, while the other were unrestricted
controls. The main hypothesis that compensatory growth
would negatively affect brain and intestinal size, as a
consequence of growth trade-offs during the
compensatory phase, could not be supported as no
significant differences were detected between the
treatment groups. Further exploratory analyses
suggested that males and females started to diverge in
both brain and intestine size at around 130 mm fork
length, with females developing relatively smaller
brains and larger intestines. The size at which the
differences appear is a typical size for smoltification
(saltwater preadaptation), and females tend to smoltify
to a higher proportion than males. Smoltification is
known to cause a more elongated morphology and
relatively smaller heads in salmonids, and the marine
lifestyle is associated with rapid growth, which could
require relatively larger intestines. Hence, these
emerging sex differences could be a consequence of
sex-biased smoltification rates. An investigation of
wild smolts of both sexes indicated no differences in
brain or intestine mass between male and female
smolts.",

animal's surroundings when in captivity to maximise its

species, particularly those used commercially.
Laboratory species could also benefit from enrichment,
but it is not always clear what constitutes an enriched
environment. The zebrafish, \bioname{Danio rerio}, is
used widely in research and is one of the most
commonly-used laboratory animals. We investigated
whether changing the structural complexity of housing
tanks altered the behaviour of one strain of zebrafish.
Fish were kept in three treatments: (1) very enhanced
(VE); (2) mildly enhanced (ME); and (3) control (CT).
Level of aggression, fertilisation success, and growth
were measured at regular intervals in a subset of fish
in each treatment group. The VE fish were more
aggressive over time than either ME or CT fish, both in
the number of attacks they made against a mirror image
and in their tendency to stay close to their reflection
rather than avoid it. Furthermore, VE fish were shorter
than CT fish by the end of the experiment, though mass
was not significantly affected. There was no
significant effect of treatment on fertilisation
success. These findings suggest that the way in which
fish are housed in the laboratory can significantly
affect their behaviour, and potentially, their growth.
The zebrafish is a shoaling species with a dominance
hierarchy, and so may become territorial over objects
placed in the tank. The enrichment of laboratory tanks
should consider aspects of the species' behaviour.",

Increasing salinity significantly affected mortality
after 24 h of exposure beginning from {$<$2} h
post-fertilisation, with 10 parts per thousand (ppt)
inducing complete lethality. The 24-h LC50 of NaCl to
embryos was estimated to be approximately 5.6 ppt.
Interestingly, 5 ppt, a test concentration only
slightly lower than the LC50, induced earlier hatching
than at lower concentrations. This earlier hatching was
also observed even when exposure was commenced at later

needed in order to grow a viable business. Farmers may
try to sell the new species in their firms' domestic
markets, but they might also look at other markets.
However, as markets are becoming more global and
competitors more international, considering
internationalization may be a necessity rather than a
choice. Using diffusion modelling, and based on results
of an online supermarket experiment, the innovation and
imitation parameters are estimated and diffusion curves
for five countries predicted in an attempt to determine
the best lead market for introducing fillets of farmed
greater amberjack (\bioname{Seriola dumerili}). The
production capacity consequences of implementing
different internationalization strategies (i.e.
``sprinkler'' and ``waterfall'') were also explored. A
waterfall strategy refers to the sequential
introduction of a product in different markets, whereas
the sprinkler strategy concerns the simultaneous
introduction of a product in multiple international
markets. Since a sprinkler approach requires many
resources and the ability to quickly ramp up production
capacity, a waterfall approach appears more suitable
for farmers of greater amberjack. Italy and Spain
appear to be the best lead markets for greater
amberjack farmers to enter first.",

cadmium, are hazardous compounds that have been shown
to affect developmental, reproductive, hepatic,

formation and skeletal development, but data is scarce.
In this work, zebrafish was used to further
characterize the anti-osteogenic/osteotoxic effects of
cadmium and gain insights into underlying mechanisms.
Upon exposure to cadmium, a reduction of the opercular
bone growth was observed in 6-days post-fertilization
(dpf) larvae and an increase in the incidence of
skeletal deformities was evidenced in 20-dpf
post-larvae. The extent and stiffness of newly formed
bone was also affected in adult zebrafish exposed to
cadmium while regenerating their caudal fin. A pathway
reporter assay revealed a possible role of the MTF-1
and cAMP/PKA signaling pathways in mechanisms of
cadmium osteotoxicity, while the expression of genes
involved in osteoblast differentiation and matrix
production was strongly reduced in cadmium-exposed
post-larvae. This work not only confirmed cadmium
anti-osteogenic activity and identified targeted
pathways and genes, but it also suggested that cadmium
may affect biomechanical properties of bone.",

by seafood, which have been less studied even in some

In this article, it is argued that researchers and

Available data from coastal fish monitoring programs
suggest a stable or increasing abundance of coastal
predatory fish as a functional group and for the
species perch in the majority of areas assessed in the

assessments is scarce, but suggest substantial declines
in the abundance of both species in most assessed

between species and areas, but include climate, habitat
exploitation, fishing, and species-interactions in the

in a gestational role. This type of viviparity is due
to the combination of unique aspects, different from
those found in the rest of vertebrates. These aspects
are: the ovary has a saccular structure; the germinal
epithelium lines the ovarian lumen; the absence of
oviducts; and the intraovarian insemination,
fertilization, and gestation. The communication of the
germinal zone of the ovary to the exterior is via the
caudal zone of the ovary---the gonoduct. The germinal
epithelium is composed of oogonia and oocytes scattered
individually or in cell nests among somatic epithelial
cells. In the ovarian stroma the follicles are included
which are formed by the oocyte, which is surrounded by
follicular cells and the vascularized theca. The
oogenesis comprises three stages: chromatin-nucleolus,
previtellogenesis, and vitellogenesis. There is no
ovulation, as the oocyte is retained in the follicle.
During the insemination, the spermatozoa enter into the
ovarian lumen and the intrafollicular fertilization
occurs, followed by intrafollicular gestation. The
intraovarian gestation of poeciliids involves
morphological characteristics associated with the
intrafollicular embryogenesis and types of nutrition,
such as lecithotrophy and matrotrophy. In
lecithotrophy, the nutrients come from the yolk
reserves stored during oogenesis, whereas in
matrotrophy the nutrients are provided by supplies from
maternal tissues to the embryo during gestation. The
maternal--embryonic metabolic interchanges converge
through the development of the association of maternal
and embryonic blood vessels, establishing a follicular
placenta.",

conclusions about a population. We used catch data to
assess differences between two types of traps for adult
sea lamprey (\bioname{Petromyzon marinus}),
submerged-funnel traps and studded-tile traps, which
are angled ramps with trickle flow leading out of the
water. The studded-tile trap at one river caught about
50\% more females than the funnel trap. It caught males
that had a smaller body size and females with a lower
gonado-somatic index (GSI). The likelihood of catching
lamprey in the studded-tile trap increased after they
had been caught once. This was not the case for the
funnel traps, which are used for mark--recapture-based
population assessment of invasive sea lamprey in the
Great Lakes. The apparent trap response caused by
studded-tile traps may have been caused by a behavioral
bias, i.e., the traps consistently attracting a subset
of the population. Use of the studded-tile trap for
population assessment should only be considered after
more is known about its recapture bias. The differences
between lamprey caught in the two trap types suggests
that a variety of trapping methods needs to be employed
in order to get a representative sample from a fish
population.",

abstract = "Alaska's salmon fisheries are one of the more
intensely managed natural resources in the world. The
state's salmon fisheries support recreational,
subsistence, and commercial harvest with multiple
billions of dollars flowing into the economy, and
define the cultural identity of many Alaskans. Fishery
management practices rely on historic records to set
policies with two goals: to meet salmon escapement
quota and to maximize salmon harvest. At the same time,
rapid social and ecological changes to the sub-Arctic
are already impacting salmon runs and fisheries
management. Combined with the inability of fishery
managers to test the outcome of proposed policy
changes, an understanding of the role social and
ecological drivers play in harvest and effort is
required. To address the two-forked problem of
understanding socio-ecological dynamics and potential
policy responses to ecological and social changes, we
(1) conducted stakeholder workshops to solicit key
system drivers, (2) built an integrated agent based
model (ABM) of the system's socio-ecological dynamics,
and (3) tested the impacts of alternative future
scenarios of ecological, social, and policy changes on
the system's outcomes. We previously constructed and
validated a high-fidelity, data-driven, agent-based
model of the Kenai River, Alaska that simulates
seasonal harvest of sockeye and {Chinook} salmon, the
fishing activities of the personal use fishery,
commercial drift, and set gillnet agents. We study the
role of key stakeholder and ecological drivers, using
the ABM decision support tool, and their implications
for fisheries management policies. Analysis of the
scenario based studies found resilience in management
of commercial fisheries to changing salmon migration
dynamics, a lack of adaptive capacity in recreational
(personal use) dipnet users to altered sockeye salmon
runs, and the possible utility of introducing
management measures in the dipnet fishery to manipulate
sockeye escapement levels. These findings represent the
usefulness of this type of ABM in assisting fishery
managers everywhere in investigating possible future
outcomes of different management or ecological
scenarios.",

(\bioname{Pleuronectes platessa}) were acquired during
exposure to two algal species as well as hypoxia.
Fourteen fish (258 {\pm} 44 g) were initially exposed
to severe hypoxia and left to recover for at least 48
h. Half of these fish were then exposed to known
harmful concentrations of P. parvum (median {\pm}
standard deviation (SD); 2.6 $ \times $ 10 5 {\pm} 0.6

half were exposed to the non-toxic alga Rhodomonas
salina (median {\pm} SD; 3.2 $ \times $ 10 5 {\pm} 0.7
$ \times $ 10 5 cells mL {-1}). During exposure to
severe hypoxia, all of the fish were able to maintain
oxygen consumption by increasing the ventilation
volume. The results from fish that were exposed to P.
parvum showed a significant decrease in oxygen
extraction (median {\pm} SD; 52.6 {\pm} 6.9 percentage
points) from pre-exposure to the end of the experiment,
as opposed to fish exposed to R. salina, which were
unaffected. These results indicate that suffocation
affects the European plaice when exposed to P. parvum.
The observed severe decrease in oxygen extraction can
be ascribed to either damage of the gill epithelia or
increased mucus secretion on the gills, as both would
limit the transfer of oxygen, and both have been
observed.",

maintaining physical health and mitigating negative
impacts to wellbeing. Recently, however, the field has
increasingly recognized the importance of positive
welfare (i.e., mental and physical states that exceed
what is necessary for immediate survival) and
accordingly introduced manipulations and indicators of
positive welfare for use in agriculture, laboratories,

positive welfare requires an in-depth knowledge of
species-specific behavior and biology, which
necessitates species-specific or, at a minimum,
taxa-specific standards. Research on positive welfare
in fish is lagging in this regard and therefore merits
further consideration. In this paper, we aim to merge
what is already known about positive welfare with the
existing fish behavior literature to develop a plan of
action for fish welfare research that will ultimately
contribute to the development of positive welfare
standards and assessment strategies for fish. We begin
by exploring the origins of positive welfare research
and then outline the physical, psychological and
species-specific areas of inquiry that can be
investigated in fish. In addition to presenting current
findings on fish motivation, emotion, potential sources
of positive welfare such as fulfillment of motivational
urges (establishing agency, engaging in exploration and
learning), and play behavior, we also identify
promising areas for future research aimed at developing

Aquatic invasive species are becoming one of the major

Placements of non-physical barriers in waterways can
help disrupt the movement of invasive fish. This study
examined the effect of a strobe-light stimulus on the
avoidance behaviour of two proxy species, juvenile
common carp (\bioname{Cyprinus carpio}) and juvenile
channel catfish (\bioname{Ictalurus punctatus}), in a
controlled laboratory environment. For each species,
three sequential treatments of pre-stimulus,
strobe-light stimulus, and post-stimulus for 30 min
periods were recorded on acclimated groups of 5
juvenile common carp and 5 juvenile channel catfish
using 15 and 13 replicates, respectively. The
distribution of juvenile common carp individuals
throughout the tank did not change significantly with
treatment, nor did cohesive grouping behaviour.
Similarly, there were no significant differences across
experimental treatments in average location/distance of
juvenile channel catfish relative to the strobe light
or degree of cohesion in response to the strobe light.
Non-physical barriers have been widely reported to vary
between species and environmental conditions. These
results suggest that strobe lights evoke no avoidance

effective barrier to inhibit movements of juvenile
invasive fishes.",

Therefore, fish calls can be an important source of

potential non-intrusive tool in aquaculture management.
Assessing fish acoustic activity, however, often
requires long sound recordings. To analyse these long
recordings automatic methods are invaluable tools to
detect and extract the relevant biological information.
Here we present a study to characterize meagre
(\bioname{Argyrosomus regius}) acoustic activity during
social contexts in captivity using an automatic
pattern-recognition methodology based on the Hidden
Markov Model. Calls produced by meagre during the
breading season showed a richer repertoire than
previously reported. Besides the dense choruses
composed by grunts already known for this species,
meagre emitted successive series of isolated pulses,
audible as `knocks'. Grunts with a variable number of
pulses were also registered. The overall acoustic
activity was concurrent with the number of spawning
events. A diel call rhythms exhibit peak of calling
activity from 15:00 to midnight. In addition, grunt
acoustic parameters varied significantly along the

to use the meagre vocal activity to predict breeding

hypothesis that the Silver Carp
(\bioname{Hypophthalmichthys molitrix}), an invasive
river carp from China, employs a prostaglandin F
2{\alpha} -derived sex pheromone that is attractive and
species-specific. Using electro-olfactogram recording
(EOG), we found that the olfactory system of this
species is acutely sensitive to three F-series
prostaglandins (PGFs) at picomolar concentrations and
that this sensitivity is enhanced when juveniles are
masculinized using androgens, consistent with
expectations of a sex pheromone. Individual PGFs had
behavioral activity but it was low, suggesting a
mixture might be important. To pursue this possibility,
we implanted carps with osmotic pumps containing
prostaglandin F 2{\alpha} (PGF 2{\alpha}), a treatment
previously shown to elicit release of a PGF-based
spawning pheromone in the Common Carp. We found that
PGF 2{\alpha} -implanted Silver Carp released a
species-specific odor that contained a blend of PGF
2{\alpha} and two of its metabolites, which
masculinized individuals detected and were attracted to
with high sensitivity. Finally, we found that a mixture
of these PGFs was attractive to masculinized Silver
Carp, while a different mixture released by Bighead
Carp was not. We conclude that Silver Carp likely use a
species-specific PGF 2{\alpha} -derived sex pheromone
that is probably released at spawning and might be
useful in its control. Confirmatory studies that
explore pheromone function in naturally mature Silver
Carp using natural odors in the field should now be
conducted to further confirm our proof-of-concept

environments, particularly by factors that act upon
species that show aggressive behavior to set social

part of the natural behavior in fish, if constant and
intense, such interactions can cause severe body
injuries, increase energy expenditure, and lead the
animals to suffer from social stress. The immediate
consequence of these factors is a reduced welfare in
social fish species. In this paper, we consider the
factors that impact on the social behavior and welfare

both in fish farms and in research; this species is
frequently used as a model for physiology and behavior
research. This is a polygynous species whose males
interact aggressively, establishing a territorial based
hierarchy, where a dominant male and several
subordinate males arise. When social stability is
shrunk, the negative effects of prolonged fighting
emerge. In this paper, we summarized how some of the
common practices in aquaculture, such as classifying
individuals by matching their sizes, water renewal,
stock density, and environment lighting affect Nile
tilapia social aggressive interactions and, in turn,
impact on its welfare. We also discuss some ways to
decrease the effects of aggressive interactions in Nile

are widely used industrial chemicals, ubiquitously
present in the environment. While BPA is a well-known
endocrine disruptor and able to affect all levels of
the teleost reproductive axis, information regarding
TBBPA on this subject is very limited. Using primary
cultures from Atlantic cod (\bioname{Gadus morhua}),
the present study was aimed at investigating potential
direct effects of acute (72 h) BPA and TBBPA exposure
on cell viability and the expression of
reproductive-relevant genes in the pituitary. The
results revealed that both bisphenols stimulate cell
viability in terms of metabolic activity and membrane
integrity at environmentally relevant concentrations.
BPA had no direct effects on gonadotropin gene
expression, but enhanced the expression of
gonadotropin-releasing hormone (GnRH) receptor 2a, the
main gonadotropin modulator in Atlantic cod. In
contrast, TBBPA increased gonadotropin transcript
levels but had no effect on GnRH receptor mRNA. In
conclusion, both anthropogenic compounds display
endocrine disruptive properties and are able to
directly interfere with gene expression related to
reproductive function in cod pituitary cells at
environmentally relevant concentrations in vitro.",

During several sampling events, 7113 barbel and nase

tagged downstream and upstream, respectively). PIT-Tag
Detection Antennas close to the top and bottom of the

months (from March to December 2017), to analyze the
performance of the fishway. Upstream passage efficiency
was greater for barbel (60\% and 25\% for barbel and

between species may be due to differences in their
size. Mean length for barbels attempting to pass was
336 mm ({\pm}47 mm) while for nases was 143 mm ({\pm}26

ascend time for nases were higher than for barbels.
Entrance efficiency was low (3.5\% and 10.8\% for

sedentary behavior, which depends on the animals' body
size, is unknown. Our objective was to analyze, for two
years, the changes in the home range of a population of
European eel (\bioname{Anguilla anguilla}, Linnaeus,
1758) in Southern Europe in relation to the animals'
body length (TL), and the influence of environmental
factors (water temperature and flow) on the local
movements of this population through observation of
their sedentary behavior. We used a
previously-validated mark--recapture methodology,
obtaining a low deviation in the estimation of the
extension of the eels' movements. Our results revealed
relatively short movements in relation to other
populations, and we hypothesize that this could be
related to the high habitat diversity and low eel
population density in the study area. The home range
size showed a high variability and dispersion among the
smallest eels, however, as TL increased, the
variability of home range size decreased, and home
ranges were larger. These changes could be associated
with the acquisition of a sedentary lifestyle. Once
eels had become sedentary, an environmental pattern was
observed between their movements and the water
temperature and flow, with larger movements observed as
the flow increased and water temperature decreased.
This suggests that the temporal and spatial scales of
observation are of crucial importance for monitoring
eel populations and for the study of population size
structure, population dynamics, and biology, which can
be used to improve conservation strategies.",

Spawning was erratic and egg quality very poor in all

from the southeastern {United States} Atlantic coast
from 2001 to 2016 were aged using sectioned sagittal
otoliths. Opaque zones formed February to June (peaking
in April). Ages ranged from 2 to 21 years, and the
largest fish measured 453 mm TL. Growth morph analysis
revealed two regionally distinct growth trajectories:
von Bertalanffy growth equations were L t = 388 (1 {-}
e {-0}.12(t+5.73)) for fish from North Carolina through
southeast Florida (northern region), and L t = 267 (1
{-} e {-0}.17(t+6.20)) for fish from the Florida Keys
(southern region). When growth was re-estimated using a
fixed t 0 value of {-0}.75 to estimate for smaller
fish, growth equations were L t = 349 (1 {-} e
{-0}.26(t+0.75)) and L t = 250 (1 {-} e
{-0}.43(t+0.75)) for fish from the northern and
southern regions, respectively. The age-invariant
estimate of natural mortality was M = 0.30 for all
fish, while age-specific estimates ranged 0.88--0.28 y
{-1} for fish aged 1--21 from the northern region and
0.89--0.47 y {-1} for fish aged 1--15 from the southern
region. This study presents the first comprehensive
analysis of life-history parameters for graysby from

qualitatively dissimilar between both eel species when

aromatase (cyp19a) mRNA levels, together with serum E2
levels, rapidly increased in artificially maturing
Japanese eels in mid-late stages of oogenesis

increase was evident in longfin eels (GSI $ \approx $

contrast to the reduced endoskeleton of zebrafish,
Periophthalmus has well developed pectoral fins with a
large and easily accessible endoskeleton. We performed
exo- and endoskeletal amputations in both species and
followed the regenerative processes. Unlike the almost
flawless exoskeletal regeneration observed in
zebrafish, regeneration following endoskeletal
amputation is often impaired in this species. This
difference is even more pronounced in Periophthalmus
where we could observe no regeneration in endoskeletal
structures. Therefore, regeneration is regulated
differentially in the exo- and endoskeleton of teleost

abstract = "Freshwater fish represent half of all fish species and
are the most threatened vertebrate group. Given their
considerable passion and knowledge, aquarium hobbyists
can play a vital role in their conservation. CARES is
made up of many organizations, whose purpose is to
encourage aquarium hobbyists to devote tank space to
the most endangered and overlooked freshwater fish to
ensure their survival. We found the CARES priority list
contains nearly six hundred species from twenty
families and two dozen extinct-in-the-wild species. The
major families were typically those with the largest
hobbyist affiliations such as killifish, livebearers,
and cichlids, the latter containing half of CARES
species. CARES included every IUCN threatened species
of Pseudomugilidae and Valenciidae, but only one
percent of threatened Characidae, Cobitidae, and
Gobiidae species. No Loricariidae in CARES were in the
IUCN red list as they have not been scientifically
described. Tanzania and Mexico contained the largest
amount of species, with the latter containing the most
endemics. Many species were classified differently than
the IUCN, including a third of extinct-in-the-wild
species classified as least concern by the IUCN. This
vast disconnect exemplifies the importance of future
collaboration and information exchange required between
hobbyists, the scientific community, and conservation
organizations.",

blastema cells formed a uniform culture and exhibited
polygonal shapes with prominent nucleus, while various
cell types were also observed after few days in culture
indicating cell differentiation. Upon treatment with
all- trans retinoic acid, zebrafish blastema cells
differentiated into neuron-like and oligodendritic-like
cells. Immunocytochemistry data also revealed the
presence of mesenchymal and neuronal cells. The
availability of blastema cell cultures could contribute
to a better understanding of epimorphic regeneration by
providing a mean to investigate the mechanisms

this protocol is simple, rapid, and cost-efficient, and

and batch 2) were built from mass spawning and reared
under industrial conditions until disease outbreak. At
the moment of the sampling (n = 500 specimens for each

photographed for image analysis (surface covered and
lesion intensity). LCDV DNA copies were quantified in
the liver by qPCR. Batch 1 had a higher surface covered
and lesion intensity than batch 2, and the body caudal
region was the lowest affected region in both batches.
The average LCDV DNA copies in liver were higher in the
batch 1 than batch 2, and they were positively
correlated with severity index (SI) categories (r 2 =
0.90--0.94). The total number of families evaluated
were 150 and 128 for batch 1 and batch 2, respectively,
with a high bias in offspring contribution by family
and broodstock. Heritabilities for weight and length
were 0.18 and 0.14 in batch 1 and 0.06 and 0.05 in
batch 2, respectively. Heritability for the number of
viral DNA copies was low ($<$0.08) in both batches.
Heritabilities for SI in binary scale were 0.32/0.33

correlations were very high and positive when growth

correlations between growth and disease traits were
moderate--high and positive in the batch 1 but negative

could be considered two separate clades by using a set
of stable and informative microsatellite markers

and type II markers (randomly picked up from genome).
Type I microsatellite markers could more sensitively
reflect the loss of genetic diversity more than type II
markers in the domestication process. All specimens
were considered native by using mtDNA COI and
microsatellites. The genetic composition of the wild
population is relatively simple, and the estimated low

6--50/459) indicated a weak but significant genetic

namaycush} were discovered in Yellowstone Lake in 1994
and caused a precipitous decrease in abundance of
native Yellowstone cutthroat trout
\bioname{Oncorhynchus clarkii bouvieri}. Suppression
efforts (primarily gillnetting) initiated in 1995 did
not curtail lake trout population growth or lakewide
expansion. An adaptive management strategy was
developed in 2010 that specified desired conditions
indicative of ecosystem recovery. Population modeling
was used to estimate effects of suppression efforts on
the lake trout and establish effort benchmarks to
achieve negative population growth ({\lambda} {$<$} 1).
Partnerships enhanced funding support, and a scientific
review panel provided guidance to increase suppression
gillnetting effort to $>$46,800 100-m net nights; this
effort level was achieved in 2012 and led to a
reduction in lake trout biomass. Total lake trout
biomass declined from 432,017 kg in 2012 to 196,675 kg
in 2019, primarily because of a 79\% reduction in
adults. Total abundance declined from 925,208 in 2012
to 673,983 in 2019 but was highly variable because of
recruitment of age-2 fish. Overall, 3.35 million lake
trout were killed by suppression efforts from 1995 to
2019. Cutthroat trout abundance remained below target
levels, but relative condition increased, large
individuals ($>$ 400 mm) became more abundant, and
individual weights doubled, probably because of reduced
density. Continued actions to suppress lake trout will
facilitate further recovery of the cutthroat trout
population and integrity of the Yellowstone Lake
ecosystem.",

important drivers of reduced global biodiversity. In
Australia, the 267 invasive plant, animal and microbial
species, established since European colonization in the
1770s, have been unequivocally declared the most
important threat to species diversity in this country.
One invasive pest, the common carp (\bioname{Cyprinus
carpio}), has been targeted in an integrated pest
management plan that might include cyprinid herpesvirus
3 (CyHV-3) as a potential biocontrol agent. The
species-specificity of the released virus (and of field
variants that will inevitably arise) has been assessed,
and the virus judged to be safe. It has also been
hypothesised that, because the virulence of the CyHV-3
will likely decline following release, the virus should
be used strategically: initially, the aim would be to
markedly reduce numbers of carp in naive populations,
and then some other, as yet uncertain, complementary
broad-scale control measure would knock-down carp
numbers even further. Brief results are included from
recent studies on the modelling of release and spread
of the virus, the ecological and social concerns
associated with virus release, and the restoration
benefits that might be expected following carp control.
We conclude that, while further work is required (on
the virus, the target species, environmental issues,
and especially the identification of a suitable
broad-scale complementary control measure), optimism
must prevail in order to ensure an eventual solution to
this important environmental problem.",

resistance to the treatments by lice. The need for a
restrictive use of pesticides to preserve treatment
efficacy has been emphasized. The use of cleaner fish
was suggested to be effective, with few or no negative
effects towards Atlantic salmon. The use of cleaner

To explore the efficacy of a consumer-based market
(i.e., invasivorism) to manage them, we developed a
conceptual model and evaluated three harvest
approaches---direct contracted removal, volume-based
incentives (``fisher-side'' control), and set-quota
harvest (``market-side'' control). We quantified the
efficacy of these approaches and potential population
impact in the Illinois River. Contracted removal was
effective for suppressing small populations at the edge
of the range but cannot support a market.
``Fisher-side'' removals totaled 225,372 kg in one
year. However, participation was low, perhaps due to
reporting requirements for fishers. The
``market-side'', set-quota approach removed $>$1.3
million kg of bigheaded carp in less than 6 months.
Larger, older fish were disproportionately harvested,
which may hinder the ability to suppress population
growth. Total density declined in one river reach, and
harvest may reduce upstream movement toward the
invasion fronts. With sufficient market demand, harvest
may control bigheaded carp. However, lack of processing
infrastructure and supply chain bottlenecks could
constrain harvest, particularly at low commodity
prices. Given the geographical scale of this invasion
and complicated harvest logistics, concerns about
economic dependence on invasivorism that encourage
stock enhancement are likely unmerited.",

to elevated discharge and egg presence. Grass carp
environmental DNA flux (copies/h) was lower when no

reared under identical environmental conditions (same
diet, same water, same experimental facility); (ii)
environment---comparing the prevalence of gonad
malformations in whitefish of the same genetic origin
reared in different water sources and/or fed with
different diets; and (iii) gene-environment
interaction---comparing the prevalence of gonad
morphological alterations in relation to the
combinations of genetics and environmental factors. Two
diets were used for the rearing experiments: either
zooplankton collected in Lake Thun which represents the
natural diet of whitefish, or an artificial dry food
which was used as control. The key finding of this
study is that the inducing factor of the gonad
malformations is contained in the zooplankton of Lake
Thun. Fish fed with this diet developed a significantly
higher prevalence of malformations than fish from any
other treatment, irrespective of the genetic origin
and/or the water source. This result could be repeated
in the two independent experiments. Importantly, the
prevalence values observed in the experimental fish fed
with Lake Thun zooplankton were similar to the
prevalence values recorded in free-ranging whitefish in
the lake. The findings of this study advance the
understanding of the causes of gonad morphological
alterations in wild fish populations.",

freshwater. Removing an aquatic invasive species
following arrival is almost impossible, and preventing

Bigheaded carp are an invasive fish spreading
throughout the Midwestern {United States} and are
threatening to enter the Great Lakes. This review
outlines the development of carbon dioxide gas (CO 2)
as a non-physical barrier that can be used to deter the
movement of fish and prevent further spread. Carbon
dioxide gas could be used as a deterrent either to
cause avoidance (i.e., fish swim away from zones of
high CO 2), or by inducing equilibrium loss due to the
anesthetic properties of CO 2 (i.e., tolerance). The
development of CO 2 as a fish deterrent started with
controlled laboratory experiments demonstrating stress
and avoidance, and then progressed to larger field
applications demonstrating avoidance at scales that
approach real-world scenarios. In addition, factors
that influence the effectiveness of CO 2 as a fish
barrier are discussed, outlining conditions that could
make CO 2 less effective in the field; these factors
that influence efficacy would be of interest to
managers using CO 2 to target other fish species, or
those using other non-physical barriers for fish.",

and sport fisheries in North America. The Roanoke River
drainage---especially Smith Mountain Lake, Leesville
Lake, and Kerr Reservoir---has popular recreational
striped bass fisheries. After construction of five
hydroelectric dams, populations became landlocked,
declined, and have been supplemented by stocking. A key
basis for responsibly augmenting populations is to
characterize genetic variation and incorporate the
findings into responsible hatchery and stocking
practices. Genetic variation at 12 microsatellite DNA
loci was evaluated among 837 striped bass representing
16 collections across the native range; populations
from rivers in South Carolina, North Carolina,
Chesapeake Bay, and Hudson River were screened to
provide context for assessing genetic structure within
the Roanoke system. Analysis of population genetic
differentiation showed landlocked Roanoke River striped
bass to be distinctive. Subject to genetic isolation,
high M ratios, and relatively low N e estimates suggest
loss of genetic variation, and relatedness analysis
showed heightened frequencies of related individuals.
These insights into population genetics, demographics,
and existing guidelines for broodstock acquisition and
mating designs can inform genetically cognizant
hatchery management and stocking for striped bass in
the Roanoke River drainage. In particular, we recommend
the use of larger numbers of breeders and factorial
mating designs to increase the genetic diversity of

toxicity at different levels of analysis. The impacts
of toxicants on neurobehavioral function have the
potential to affect many different life-history traits,

wild. We propose that carefully-controlled laboratory
experiments on different behavioral domains---including
anxiety, aggression, and exploration---can increase our
understanding of the ecotoxicological impacts of
contaminants, since these domains are related to traits
such as defense, sociality, and reproduction, directly
impacting life-history traits. The effects of selected
contaminants on these tests are reviewed, focusing on

ingredients for aqua-feeds where the microorganisms are
considered non-viable and are used primarily to provide
protein, lipids or specific nutritional components.
Among the SCI, there is a generalised dichotomy in
terms of their use as either single-cell protein (SCP)
resources or single-cell oil (SCO) resources, with SCO
products being those oleaginous products containing 200
g/kg or more of lipids, whereas those products
considered as SCP resources tend to contain more than
300 g/kg of protein (on a dry basis). Both SCP and SCO
are now widely being used as protein/amino acid
sources, omega-3 sources and sources of bioactive
molecules in the diets of several species, with the
current range of both these ingredient groups being
considerable and growing. However, the different array
of products becoming available in the market, how they
are produced and processed has also resulted in
different nutritional qualities in those products. In
assessing this variation among the products and the
application of the various types of SCI, we have taken

six kinds of disease, four of which (Vibrio sp.,

Lymphocystis arose only in the M.P group and abdominal
inflation only in the E.P group at both farms. As for
mortality in the present experiment, the numbers were
1047 at Da-Hae farm and 1167 at Global farm, with more
fish dying in the E.P tanks than in the M.P tanks. By
multiplying the number of deaths by selling price, the
economic losses were \$9650 and \$10,756, respectively.

American ecosystems since its introduction over a
century ago. In many watersheds, its abundance appears
to be driven by source-sink dynamics in which carp
reproduce successfully in peripheral ponds that lack
egg/larva micro-predators which then serve as sources
of recruits for deeper lakes. This manuscript describes
how carp were sustainably reduced in two chains of
lakes by disrupting source-sink dynamics in three
steps. First, we ascertained whether lakes had
problematic densities of carp that could be explained
by source-sink dynamics. Second, ways to control
recruitment were developed and implemented including:
(i) aerating source ponds to reduce hypoxia and
increase micro-predator abundance, (ii) blocking carp
migration, and (iii) locating and removing adults from
sinks using targeted netting guided by Judas fish.
Third, we monitored and adapted. Using this strategy,
the density of carp in 3 lakes in one chain was reduced
from 177 kg/ha to $ \approx $100 kg/ha in 3 years and
held constant for a decade. Similarly, adult density
was reduced from 300 kg carp/ha in 2 lakes in the other
chain to 25 kg/ha. Once carp densities were low,
aluminum sulfate treatments became reasonable and once
conducted, water quality improved.",

organic matter (OM) and crude protein (CP) was
unaffected (p $>$ 0.782--0.901) by the faeces
collection method (i.e., siphoning or stripping), with
correlation coefficient (r) of 0.98, 0.99 and 0.93
between AD values for DM, OM and CP, respectively,
following siphoning and stripping. The AD (\%) of DM,
OM, CP and gross energy (GE) in the test ingredients
differed (p {$<$} 0.0001). The AD (\%) of DM and OM was
lowest in BSY and DW, followed in increasing order by
ML, MSH, FF, FSH and CB. In general, the AD (\%) of CP
was high ($>$76\%), but with a low value (46\%) for DW.
The AD (\%) of GE was closely correlated (r = 0.96)
with the AD of OM. In conclusion, FSH, MSH, CB, FF, BSY
and ML have acceptable protein digestibility to be used
in tilapia diet formulation.",

nearshore ecosystems. However, their movement ecology
in high-energy surf areas remains largely unknown due
to the notorious difficulties in conducting research in
these environments. Using a blimp as an aerial platform
for video surveillance, we overcame some of the
limitations of other tracking methods, such as the use
of tags and drones. This novel technology offered
near-continuous coverage to characterise the fine-scale
movements of stingrays in a surf area in Kiama,
Australia, without any invasive procedures. A total of
98 stingray tracks were recorded, providing 6 h 27 min
of movement paths. The tracking data suggest that
stingrays may use a depth gradient located in the
sandflat area of the bay for orientating their
movements and transiting between locations within their
home range. Our research also indicates that stingray
behaviour was influenced by diel periods and tidal
states. We observed a higher stingray occurrence during
the afternoon, potentially related to foraging and
anti-predatory strategies. We also saw a reduced route
fidelity during low tide, when the bathymetric
reference was less accessible due to stranding risk.
Considering the increasing threat of anthropogenic
development to nearshore coastal environments, the
identification of these patterns can better inform the
management and mitigation of threats.",

the most abundant pest fish species in Australia,
detrimental to ecosystem integrity and values, and in
need of suitable management solutions. In January 1995,
this destructive pest was discovered in two large,
connected Tasmanian lakes --- Lakes Crescent (23 km 2)
and Sorell (54 km 2). After an initial assessment, carp
were immediately contained to these waters using
screens to prevent their escape down-stream, followed
by swift legislation to enforce closure of the lakes to
the public. Assessment and evaluation of carp numbers
occurred throughout the eradication program, with
effort focused on Lake Crescent. Beginning with
undirected removal, techniques progressively evolved to
more sophisticated targeted removal with assistance
from biotelemetry, in conjunction with gill netting and
electro-fishing. Real-time population estimates and in
situ observations resulted in a detailed cumulative
understanding of carp population dynamics, behaviour
and seasonal habitat choice. This allowed strategic
deployment of fences to block access to marshes, and
the installation of steel traps within the fences.
These gears specifically prevented spawning
opportunities, while concurrently capturing mature
fish. Following 12 years of adaptive and integrated
effort, 7797 carp (fry, juvenile and adult) were
captured from Lake Crescent, with the last carp being
caught in December 2007. The subsequent 14 years of
monitoring has not resulted in the capture of any carp,
confirming the successful eradication of carp from Lake
Crescent. These management practices have been
successfully replicated in the larger Lake Sorell,
where 41,499 carp (fry, juvenile and adult) have been
removed. It is now estimated that there are few, if any
carp remaining. Collectively, the techniques and
strategies described here were reliable, and can be
applied as a model to control or eradicate pest
populations of carp in freshwater lakes elsewhere.",

has been a necessary component of its fishery
restoration and recovery goals for 30 years. While
adopting the approach of the larger and established sea

local differences emerged that shifted management focus
and effort as the program evolved. Increased investment
in lamprey assessment and monitoring revealed
under-estimations of population density and
distribution in the basin, where insufficient control
efforts went unnoticed. As control efforts improved in
response to a better understanding of the population,
the effects of lamprey on the fishery lessened. A
long-term evaluation of fishery responses when lamprey
control was started, interrupted, delayed, and enhanced
provided evidence of a recurring relationship between
the level of control effort applied and the measured
suppression of the parasitic sea lamprey population.
Changes in levels of control efforts over time showed
repeatedly that measurable suppression of the parasitic
population required effective control of 80\% of the
known larval population. Understanding the importance
of assessment and monitoring and the relationship
between control effort and population suppression has
led to recognition that a comprehensive, not

fisheries science, it was common to fit one growth

size-at-age data. However, in recent years, fisheries
science has seen an increase in the number of growth
models available and the evaluation of multiple growth
models for a given species or study. We reviewed n =
196 peer-reviewed age and growth studies and n = 50
NOAA (National Oceanic and Atmospheric Administration)
regional stock assessments to examine trends in the use
of growth models and model selection in fisheries over
time. Our results indicate that the total number of age
and growth studies increased annually since 1988 with a
slight proportional increase in the use of multi-model
frameworks. Information theoretic approaches are
replacing goodness-of-fit and a priori model selection
in fisheries studies; however, this trend is not
reflected in NOAA stock assessments, which almost
exclusively rely on the von Bertalanffy growth model.
Covariates such as system (e.g., marine or fresh),
location of study, diet, family, maximum age, and range
of age data used in model fitting did not contribute to
which model was ultimately the best fitting, suggesting
that there are no large-scale patterns of specific

environment suitable for survival. However, little is
known about the mechanisms regarding detection and
selection of salinity environments in fish. This study
involved the establishment of a simple aquarium system
in which fish can swim between freshwater (FW) and
seawater (SW) in a single tank. In this tank, the lower
level contained SW, the upper level contained FW, and
the FW and SW levels were clearly separated as
different salinity areas. Behavioral experiments of
salinity environment selection using this simplified
system to evaluate salinity preference showed that
FW-acclimated medakas preferred FW to SW. In contrast,
SW-acclimated medakas preferred SW to FW. These results
indicate that euryhaline medakas prefer the saline
habitats to which they are acclimated, when able to
select the salinity environment. We identified the
taste receptor type-2 and polycystic kidney disease
2-like 1 genes as possibly related to high-salinity
taste in medaka. The expression of these genes
increased at certain time points after SW challenges.
In this study, we established an aquarium system to
facilitate a simple experiment for salinity preference.
Our results suggest that the medaka is good model for
research related to seawater environment selection in

treated with a monoamine-depleting agent, reserpine, or
with a monoamine oxidase inhibitor, pargyline, two

employed to completely prevent spinal cord functions of
the fish in another group. Compared with the control
group (CS only), the reserpine, pargyline, and SCD
groups showed significantly inhibited delayed

Although modifying spillway gate operation is the least
expensive option, its efficacy drops at high flows, so
lock deterrents and/or removal using fishing/trapping
are required to move towards complete blockage.
Improved deterrent efficacy could also offset the need

of the study show that China\prime s fishery subsidies
are negatively correlated with fishing. On average, for
each 1\% increase in fishery subsidies, fishing will
decrease by 2.9\%. That is to say, in general, fishery
subsidies are conducive to the sustainable development
of fisheries. The results of heterogeneity analysis
based on geographic location and economic development
level show that fishery subsidies do not have a
palpable negative influence on fishing in coastal areas

influence on fishing in inland areas or underdeveloped
regions. The deterioration of the fishing environment

bleaching events in shallow waters triggered by thermal
anomalies and marine heatwaves linked to climate
change, a trend that is replicated worldwide. As sea
surface thermal anomalies are assumed to lessen with
depth, mesophotic deep reefs have been hypothesized to
act as refuges from anthropogenic and natural
disturbances, the \lq deep reef refugia hypothesis'
(DRRH). However, evidence supporting the DRRH is either
inconclusive or conflicting. We address this by
investigating four assumptions of the DRRH focusing on
the symbiotic association between anemones and
anemonefish. First, we compare long-term temperature
conditions between shallow (8 m) and mesophotic sites
(50 m) on the island of Moorea from 2011--2020. Second,
we compare the densities of the orange-fin anemonefish,
\bioname{Amphiprion chrysopterus} between shallow and
mesophotic (down to 60 m) reefs across three
archipelagos in French Polynesia. Finally, we compare
the percentage of anemone bleaching, as well as
anemonefish reproduction, between shallow and
mesophotic reefs. We found that the water column was
well mixed in the cooler austral winter months with
only a 0.19 \degree C difference in temperature between
depths, but in the warmer summer months mixing was
reduced resulting in a 0.71--1.03 \degree C temperature
difference. However, during thermal anomalies, despite
a time lag in warm surface waters reaching mesophotic
reefs, there was ultimately a 1.0 \degree C increase in
water temperature at both 8 and 50 m, pushing
temperatures over bleaching thresholds at both depths.
As such, anemone bleaching was observed in mesophotic
reefs during these thermal anomalies, but was buffered
compared to the percentage of bleaching in shallower
waters, which was nearly five times greater. Our
large-scale sampling across French Polynesia found
orange-fin anemonefish, A. chrysopterus, in mesophotic
zones in two high islands and one atoll across two
archipelagos, extending its bathymetric limit to 60 m;
however, orange-fin anemonefish densities were either
similar to, or 25--92 times lower than in shallower
zones. Three spawning events were observed at 50 m,
which occurred at a similar frequency to spawning on
shallower reefs at the same date. Our findings of
thermal anomalies and bleaching in mesophotic reefs,
coupled with mainly lower densities of anemonefish in
mesophotic populations, suggest that mesophotic reefs
show only a limited ability to provide refugia from
anthropogenic and natural disturbances.",

The purpose of this study was to call SNPs from
rapid-growing (RG) and slow-growing (SG) individuals'
transcriptomes and use DNA pool sequencing to assess
the reliability of SNPs. Two parameters were applied to
detect SNPs. One parameter was the p -values generated
using Fisher's exact test, which were used to calculate
the significance of allele frequency differences
between RG and SG. The other one was the AFI (minor
allele frequency imbalance), which was defined to
highlight the fold changes in MAF (minor allele
frequency) values between RG and SG. There were 216,015
hypothetical SNPs, which were obtained based on the
transcriptome data. Finally, 104 high-quality SNPs and
96,819 low-quality SNPs were predicted. Then, 18
high-quality SNPs and 17 low-quality SNPs were selected
to assess the reliability of the detection process.
Here, 72.22\% (13/18) accuracy was achieved for
high-quality SNPs, while only 52.94\% (9/17) accuracy
was achieved for low-quality SNPs. These SNPs enrich
the data for population genetics studies of P. vannamei

According to the ELISA results using human dermal

activity by up to 21.89\% and 12.04\%, respectively, in
a concentration-dependent manner, and increased PIP
synthesis by up to 62.24\% in a concentration-dependent
manner. The RT-PCR test results using mRNA showed the

can maintain and improve skin tissue conditions through

abstract = "The aim of this work was to reuse a fish processing
waste, shrimp head powder (SHP), for the production of
prodigiosin (PG) via microbial technology and to assess
its potential bioactivities. PG was produced in a 12
L-bioreactor system, and the highest PG productivity of
6310 mg L \minus 1 was achieved when \bioname{Serratia
marcescens} CC17 was used for fermentation in a novel
designed medium (6.75 L) containing 1.5\% C/N source
(SHP/casein = 9/1), 0.02\% K 2 SO 4, ans 0.025\% Ca 3
(PO 4) 2, with initial pH 7.0, and fermentation was
performed at 28 \degree C for 8 h. The purified PG
showed moderate antioxidants, efficient anti-NO
(anti-nitric oxide), and acetylcholinesterase (AChE)
inhibitory activities. In a docking study, PG showed
better binding energy scores (\minus 12.3 kcal/mol) and
more interactions (6 linkages) with several prominent
amino acids in the biding sites on AChE that were
superior to those of Berberine chloride (\minus 10.8
kcal/mol and one linkage). Notably, this is the first
investigation using shrimp heads for the mass
bioproduction of PG with high productivity, and Ca 3
(PO 4) 2 salt was also newly found to significantly
enhance PG production by S. marcescens. This study also
provided available data on the anti-NO and anti-AChE
effects of PG, especially from the docking simulation
PG towards AChE that was described for the first time
in this study. The above results suggest that SHP is a
good material for the cost-effective bioproduction of
PG, which is a potential candidate for anti-NO and
anti-Alzheimer drugs.",

diets were formulated with increasing HIM/FM
replacement rate (the control diet contained 20\% FM).
Mortality rates, growth performances, and feed
consumptions were measured, and fish intestine samples
were collected for histological and enzymatic analysis.
After 49 days, all groups almost tripled their initial
body weight (cumulative body weight gain ranged between
143.9 and 155.2 mg), and no statistically significant
differences among treatments were observed in relation
to growth performances and histological traits.
Contrarily, trypsin, alkaline phosphatases, and alpha
amylase--glucoamylase activities were significantly
reduced when the FM replacement rate was increased. In
conclusion, HIM may represent an alternative to FM,
since no adverse effects were observed when it was
included up to 20\% in the zebrafish diet, even when
replacing 100\% of the FM.",

scientific sampling approach. Six CAMP stations and six
stations selected using a stratified random design were
sampled at ten estuaries. A permutational-MANOVA
revealed nekton assemblages were generally not
significantly different between the two sampling
designs. The current six CAMP stations are sufficient
to detect the larger differences in species abundances
that may indicate differences in estuary condition. The
predicted increase in precision (2\%) with twelve

increased sampling effort. CAMP's scientific utility is
not limited by station selection bias or numbers.

Here, we collected 21 time series of demersal fishes

nonstationary responses in temperate waters of the
northwestern North Pacific (NWP). We showed that these
demersal fishes experienced state shifts in
approximately 1986/87, accompanied by abrupt warming

demersal fishes and sea surface temperature (SST) were
found to change between the two identified eras (i.e.,
a weak relationship before 1986 and a strong negative
relationship after 1986), which may be primarily caused
by the alternating dominance of the East Asian winter
monsoon and mega-ENSO on SST in temperate waters of the
NWP. The identified climate-induced nonstationary
responses of demersal fishes to SST variability in this
study may provide implications for understanding

with a triangular cross-section and a flat ``V''-shaped
notch. Their extensive use is a consequence of their
utility in the measurement of both low and high flow
conditions. However, depending on their size, local
morphology and river discharge can act as full or
partial hydraulic barriers to fish migration. To
address this concern, the present work studies fish
passage performance over flat-V weirs considering their
hydraulic performance. For this, radio-tracking and
video-monitoring observations were combined with
computational fluid dynamics (CFD) models in two flat-V
weirs, using Iberian barbel (Luciobarbus bocagei) as
the target species. Results showed that fish passage is
conditioned by both hydraulic and behavioral processes,
providing evidence for scenarios in which flat-V weirs
may act as full or partial barriers to upstream
movements. For the studied flat-V weirs, a discharge
range of 0.27--8 m 3 /s, with a water drop difference
between upstream and downstream water levels lower than
0.7 m and a depth downstream of the weir of higher than
0.3 m can be considered an effective passage situation
for barbels. These findings are of interest for
quantifying flat-V weir impacts, for engineering
applications and for establishing managing or
retrofitting actions when required.",

(\bioname{Trichiurus lepturus}, also known as T.
japonicus) is a commercially important element of
Chinese fisheries. Hairtail has long been widely
exploited. Due to overfishing, however, its production
declined over the years. One of solutions to this
dilemma is to institute reasonable fishery policies.
Generally, skillful short-term and long-term prediction
of fish catch is a central tool for guiding the
development of fishery policy. Accurate predictions
require a comprehensive understanding of the
relationship between fluctuations in fish catch and
variability in both fishing effort and marine
environmental conditions. To investigate the combined
impact of fishing effort and marine environments on
hairtail catch and to develop models to predict
hairtail catch, we applied empirical dynamic modeling
(EDM) to data on East China Sea fisheries, including
hairtail catch, fishing effort, and marine
environmental factors. EDM is an equation-free approach
that enables the investigation of various complex
systems. We constructed all possible multivariate EDM
models to investigate the potential mechanisms
affecting hairtail catch. Our analysis demonstrates
that all key environmental factors (salinity, summer
monsoon, sea surface temperature, precipitation, and
power dissipation index of tropical cyclones) have an
impact on nutrient supply, which we suggest is the
central factor influencing hairtail catch. Finally, our
comparison of EDM models with parametric models
demonstrates that EDM models overwhelmingly outperform
parametric models in analysis of these complex
interactions.",

Given the temperature range of the experimental

After G. affinis ' introduction, the thermal preference

(1) the damage they cause (one article); (2) techniques
to ascertain their presence (one article); (3)
techniques to restrict their movement (one article);
(4) strategies to control them (three articles); and
(5) lessons learned from ongoing management efforts
(five articles). This introduction notes that
successful management efforts share a few approaches:
(1) they develop and use a deep understanding of local
species and their abundance as well as distribution;
(2) they focus on reducing reproductive success; (3)
they use multiple complimentary control strategies; and
(4) they use a long-term approach.",

abstract = "Evidence of pain perception in fish is well
established, but analgesic use in aquaculture is
limited. The objective was to investigate the
comparative pharmacokinetics of flunixin administered
intramuscularly (IM) and meloxicam administered IM or
orally (PO) in tilapia. Two hundred and seventy fish
were assigned to 1 of 3 treatment groups: flunixin
meglumine IM (2.2 mg/kg); meloxicam IM (1 mg/kg); or
meloxicam PO (1 mg/kg). Blood and tissue samples were
collected from 6 fish per treatment at 14 time points
for 10 days. Drug concentrations were determined using
ultra-high-pressure liquid chromatography coupled with
mass spectroscopy. Plasma concentration versus time
data were analyzed with a non-compartmental approach
using a commercially available software. Flunixin
reached a mean maximum concentration (C max) of 4826.7
ng/mL at 0.5 h, had a terminal half-life (T 1 / 2) of
7.34 h, and an area under the concentration--time curve
extrapolated to infinity (AUC INF\_obs) of 25,261.62
h{\cdot}ng/mL. Meloxicam IM had a T 1 / 2 of 9.4 h
after reaching a C max of 11.3 ng/mL at 2 h, with an
AUC INF\_obs of 150.31 h{\cdot}ng/mL. Meloxicam PO had
a T 1 / 2 of 1.9 h after reaching a C max of 72.2 ng/mL
at 2 h, with an AUC INF\_obs of 400.83 h{\cdot}ng/mL.
Tissue concentrations of both drugs were undetectable
by 9 h. Flunixin reached a sufficient plasma
concentration to potentially have an analgesic effect,
while meloxicam, when administered at the given dosage,
likely would not.",

examination of how small a spatial scale on which this

bodies that share a large proportion of their flow,
would be useful for guiding aquatic invasive species

in northern pike (\bioname{Esox lucius}) otoliths to
estimate their provenance between two reservoirs in the
Upper Yampa River Basin, Colorado, USA. This is a
challenging study area as these reservoirs are only
11-rkm apart on the same river and thus share a high
proportion of their inflow. We found that three
isotopes (86 Sr, 137 Ba, and 55 Mn) were useful in
discriminating between these reservoirs, but their
signatures varied annually, and the values overlapped.
Strontium isotope ratios (87 Sr/ 86 Sr) were different
between sites and relatively stable across three years,

northern pike provenance. Our study demonstrates the

experiment, the physiological status was characterized.
Subsequently, the specimens of the CTRL and CEO2 groups

abstract = "The Chinese mitten crab (\bioname{Eriocheir sinensis})
is a representative catadromous invertebrate of the
Yangtze River and a commercial species widely
cultivated in China. Both cultivated and wild crabs
suffer from a variety of parasites and pathogens, which
can result in catastrophic economic losses in
aquaculture revenue. Polyascus gregaria, a parasitic
barnacle with a highly derived morphology, is
specialized in invading these crabs. This study
examines the immunological mechanism in E. sinensis
infected with P. gregaria. Tandem mass tags (TMT), a
specialized method of mass-spectrometry, was used to
analyze the infection by P. gregaria resistance at the
protein level. In the hepatopancreas of infected crabs,
598 proteins differentially expressed relating to
physiological change, of which, 352 were upregulated
and 246 were downregulated. Based on this differential
protein expression, 104 GO terms and 13 KEGG pathways
were significantly enriched. Differentially expressed
proteins, such as ATG, cathepsin, serpin, iron-related
protein, Rab family, integrin, and lectin, are
associated with the lysosome GO term and the
autophagy-animal KEGG pathways, both of which likely
relate to the immune response to the parasitic P.
gregaria infection. These results show the benefit of
taking a detailed, protein-level approach to
understanding the innate immune response of aquatic
invertebrates to macroparasite infection.",

lake virus (TiLV), is an emerging fish virus that
primarily affects tilapines. However, the virus has
also been detected in a few non-tilapines. As tilapia
is generally farmed in polyculture systems along with
carps in South Asian countries, there is a likelihood
that TiLV-infected tilapia can transmit the virus to
the co-cultured species. In view of the above, the
susceptibility of three carp species, namely catla
(\bioname{Catla catla}), mrigal (\bioname{Cirrhinus
mrigala}) and silver carp (\bioname{Hypophthalmichthys
molitrix}) was evaluated vis-{\`a}-vis tilapia,
following experimental infection with TiLV. No clinical
signs and histopathological alterations could be
observed in carps. RT-qPCR revealed that TiLV copy
numbers in liver and brain of all the three carps were
almost negligible and did not show any increase with
time, suggesting that the virus did not replicate in
liver and brain, the target organs of TiLV. Further,
TiLV could not be isolated from pooled liver and brain
tissues of carps using permissive CFF cell line. On the
contrary, in tilapia, typical clinical signs and
histopathological lesions were observed and there was
significant increase in TiLV copy number up to 6 days
post-injection. Furthermore, the virus was successfully
isolated from pooled liver and brain tissue of infected
tilapia. From the above findings, it could be concluded
that C. catla, C. mrigala and H. molitrix are resistant
to TiLV infection and unlikely to be carriers for this
virus.",

Previously, vaccination of fish with extracellular

antibody-mediated immune response against vAh
infection. In this study, we analyzed IgM transcripts
that were differentially expressed in the head kidney
and liver of ECP-immunized and mock-immunized (control)

Quantitative PCR analysis indicated that immunized fish
produced significantly more IgM transcripts than
control fish. Full-length IgM heavy chain cDNA was
cloned, which encoded typical IgM peptide, including
signal peptide, variable domain (VH), constant domain
(CH), and carboxyl terminal peptide. Great sequence
diversity was revealed in a VH segment, with the third
complementarity diversity region (CDR3) being most
variable. Using germline VH gene grouping method,
variants (clones) of VH characterized in this study
belonged to nine VH families. The most unique variants
(approximately 49\%) were found in the VH2 family.
Vaccinated fish apparently had more unique variants
than in the control fish. There were 62\% and 79\% of

vaccinated fish, respectively, while 44\% and 27\%
unique variants in the head kidney and liver of control

exhibited a decline in genetic diversity and a
significant difference with the remaining populations
after fitting the isolation by distance model. Pairwise

and significant differentiation was found between

abstract = "In ectotherm species, environmental temperature plays
a key role in development, growth, and survival. Thus,
determining how temperature affects fish populations is
of utmost importance to accurately predict the risk of
climate change over fisheries and aquaculture, critical
to warrant nutrition and food security in the coming
years. Here, the potential effects of abnormal thermal
regimes (24, 28 and 32 {$^\circ $}C; TR24, TR28, and
TR32, respectively) exclusively applied during
embryogenesis in tropical gar (\bioname{Atractosteus
tropicus}) has been explored to decipher the potential
consequences on hatching and growth from fertilization
to 16 days post-fertilization (dpf), while effects on
skeletal development and body morphology were explored
at fertilization and 16 dpf. Egg incubation at higher
temperatures induced an early hatching and mouth
opening. A higher hatching rate was obtained in eggs
incubated at 28 {$^\circ $}C when compared to those at
24 {$^\circ $}C. No differences were found in fish
survival at 16 dpf, with values ranging from 84.89 to
88.86\%, but increased wet body weight and standard
length were found in larvae from TR24 and TR32 groups.
Thermal regime during embryogenesis also altered the
rate at which the skeletal development occurs. Larvae
from the TR32 group showed an advanced skeletal
development, with a higher development of cartilaginous
structures at hatching but reduced at 16 dpf when
compared with the TR24 and TR28 groups. Furthermore,
this advanced skeletal development seemed to determine
the fish body morphology. Based on biometric measures,
a principal component analysis showed how along
development, larvae from each thermal regime were
clustered together, but with each population remaining
clearly separated from each other. The current study
shows how changes in temperature may induce
craniofacial and morphological alterations in fish
during early stages and contribute to understanding the
possible effects of global warming in early development
of fish and its ecological implications.",

CMSY (version CMSY\_2019\_9f. R) to assess maximum
sustainable yield (MSY) and related indicators for
freshwater bream, roach, pike-perch, and European

identified, while the stocks of freshwater bream and
European perch were sustained. As the CMSY model does
not consider the impact of environmental factors, the
decline in roach stock may be attributed to the
increase in salinity rather than to overfishing. In the
case of freshwater bream and pike-perch, the method
cannot consider the increase of the percentage of
small-sized fishes in catches due to the allowance of
low-selectivity gears in the fishery. Additionally, in
the case of the pike-perch, the model does not take
into account the interannual fluctuations in the
stock-recruitment system. The assessment of the
European perch stock can be considered to be good.

should account for discard mortality in fisheries if it

assessments are to lump dead discards with landings,
treat dead discards as their own fleet, or link them
conversely with landings through use of a retention
function. The first approach (lumping) implicitly
assumes that the selectivity of landings applies also
to discards. In many cases, that assumption is false,
for example, if discards comprise smaller fish than do
landings. The latter two approaches avoid the
assumption by modeling discards explicitly with their
own selectivity pattern. Here, we examine these
approaches to modeling discards. Using a simulation
study, we demonstrate that the two approaches to
modeling discards explicitly can provide identical
results under both static and time-varying conditions.
Then, using a stock assessment case study of red
grouper \bioname{Epinephelus morio} in the U.S. Gulf of

to modeling discards can provide different outcomes,
with implications for the resultant management advice.

positive effect of the enzyme treatment on the

diet containing non-treated ingredients. Results of
growth and feed efficiency that were obtained in a
second long-term trial developed for 148 days under
real production conditions evidenced the equivalence

cytokine responses to infectious diseases in the common

stages of zebrafish (Danio rerio) scale development.
Four developmental stages, namely stage I ($ \approx

grow), stage III ($ \approx $41 dpf, the period in

transcriptome analysis. WGCNA (weighted correlation
network analysis) and DEG (differentially expressed

Based on the comparison between stage II and stage I,
54 hub-genes were identified by WGCNA analysis. Key
genes including the Scpp family (Scpp7, Scpp6, Scpp5,

Rcvasa appeared to be specifically expressed in the
testis and ovary, among 13 tissues analyzed. In
addition, annual changes in Rcvasa expression levels
were examined in the gonads by quantitative real-time
PCR (qRT-PCR). The expression of Rcvasa in the testis
first increased significantly at 120 dph (stage
II--III), then stabilized as the testis developed from
185 dph (stage III) to 360 dph (stage V). During the
development of the ovary (stage I to II), the
expression of Rcvasa first increased and reached the
highest level at 210 dph (stage II), then decreased.
Furthermore, the results of chromogenic in situ
hybridization (CISH) revealed that Rcvasa mRNA was
mainly expressed in germ cells and barely detected in
somatic cells. In the testis, Rcvasa mRNA signal was
concentrated in the periphery of spermatogonia, primary
spermatocytes, and secondary spermatocytes and was
significantly weaker in spermatids and spermatozoa. In
the ovary, Rcvasa mRNA signal was uniformly distributed
in the perinuclear cytoplasm and was intense in early
primary oocytes (stage I and II). These findings could

integrated effects of dietary protein source and
protein/carbohydrate (P/CH) ratio on gilthead seabream
gut histomorphology, microbiota composition, digestive
enzymes activity, and immunological and oxidative
stress-related gene expressions. Four isolipidic diets:
two fishmeal-based (FM) and two plant feedstuff
(PF)-based diets, with P/CH ratios of 50/10 or 40/20
each (FM-P50/CH10; FM-P40/CH20; PF-P50/CH10;
PF-P40/CH20), were tested. PF-based diets lead to more
histomorphological alterations than FM-based diets.
P/CH ratio had no relevant effect on gut
histomorphology. Gut mucosa of fish fed PF-based diets
presented a higher number of operational taxonomic
units, and richness and diversity indices, while the
P/CH ratio did not affect those parameters. The
{\alpha}-amylase activity was lower in fish fed with
PF-based diets and in fish fed the P40/CH20 diets.
Regarding the immune-related genes, only
cyclooxygenase-2 was affected, being higher in fish fed
the P50/CH10 diets than the P40/CH20 diets. Fish fed
the FM-based diets presented higher expression of
glutathione reductase and glutathione peroxidase, while
fish fed the P50/CH10 diet had higher expression of
superoxide dismutase. In conclusion, PF-based diets can
compromise gut absorptive and digestive metabolism, but
decreasing the dietary P/CH ratio had little effect on
the parameters measured.",

pelagic environment (20.7\%) or are euryhaline (7.3\%).
The benthic littoral species are the most numerous
Adriatic fishes, representing 40\% of all species

observed between sagitta shape changes and fish

the post-flexion larval stage (Post-FLS), it
corresponded with the formation period of individual

indicated that lapilli were the optimal otolith for age

demonstrated that the lapillus developmental increments
were deposited daily, and the first increment formed at

abstract = "In recent years, much attention has been focused on
the impact of climate change, particularly via ocean
acidification (OA), on marine organisms. Studying the
impact of OA on long-living organisms, such as sharks,
is especially challenging. When the ocean waters absorb
anthropogenic carbon dioxide (CO 2), slow-growing shark
species with long generation times may be subjected to
stress, leading to a decrease in functionality. Our
goal was to examine the behavioral and physiological
responses of sharks to OA and the possible impacts on
their fitness and resilience. We conducted a systematic
review in line with PRISMA-Analyses, of previously
reported scientific experiments. We found that most
studies used CO 2 partial pressures (pCO 2) that
reflect representative concentration pathways for the
year 2100 (e.g., pH $ \approx $7.8, pCO 2 $ \approx
$1000 {\mu}atm). Since there is a considerable
knowledge gap on the effect of OA on sharks, we
utilized existing data on bony fish to synthesize the
available knowledge. Given the similarities between the
behaviors and physiology of these two superclasses' to
changes in CO 2 and pH levels, there is merit in
including the available information on bony fish as
well. Several studies indicated a decrease in shark
fitness in relation to increased OA and CO 2 levels.
However, the decrease was species-specific and
influenced by the intensity of the change in
atmospheric CO 2 concentration and other anthropogenic
and environmental factors (e.g., fishing, temperature).
Most studies involved only limited exposure to future
environmental conditions and were conducted on benthic
shark species studied in the laboratory rather than on
apex predator species. While knowledge gaps exist, and
more research is required, we conclude that
anthropogenic factors are likely contributing to shark
species' vulnerability worldwide. However, the impact
of OA on the long-term stability of shark populations
is not unequivocal.",

and vulnerable life-history traits, are highly
threatened by fishing activities. Indeed, between 53\%
and 71\% of Mediterranean elasmobranch species are at
risk of extinction. In this context, using the
abundance MSY (AMSY) model, the present study provides
an assessment of 20 batoids and 16 shark species in the
Strait of Sicily, sampled during a bottom trawl survey
from 1995 to 2020. Overall, the outputs underline a
progressively improving condition for shark and ray
assemblages of both shelf and eurybathic zones. As for
slope-dwelling species, a horseshoe-shaped dynamic,
characterized by a progressive decrease in relative
harvesting pressure and an increase in relative biomass
followed by an increase in fishing pressure and
decrease in biomass, was detected. The dynamics of the
Elasmobranchii living in the Strait of Sicily appear to
be affected by changes in the fishing patterns of
trawlers, showing a shift from shallow water to bathyal
fishing grounds and targeting deep-water red shrimp. In
this context, it seems wise to limit the impact of
deep-water fisheries on Elasmobranchii by reducing
fishing efforts and implementing ad hoc management
measures aimed at safeguarding these vulnerable

estuary were rectangular and elliptic, whereas in the
tributaries they presented a more round and circular
form. Eels collected in both habitats were mostly
yellow-stage eels with a similar age range, but the
eels from the tributaries showed smaller length-at-age

estuary. Additionally, the sex ratio was skewed towards
males in the tributaries and females in the estuary.

flounder (Paralichthys olivaceus) have sex-biased
expression patterns, but their target genes and how
they work in the development of the gonads are rarely
known. Anti-M{\"u}llerian hormone (AMH) can inhibit the
development of Muller's duct in female mammals and
regulate the formation of gametes after sexual
maturity. There is no Muller's duct in teleosts, but
the amh gene still exists. Knockout of amh results in
sex reversal from male to female. Therefore, it is
essential to explore the relationship between the
miR-200 family and amh to clarify what role miR-200
plays in the development of the gonads. In Japanese
flounder, the two binding sites for the miR-200 family
in the 3{\prime}UTR of amh were found through
bioinformatic prediction. Double luciferase and green
fluorescent protein reporter experiments demonstrated
amh to be directly targeted by miR-200a and miR-200b.
Moreover, miR-200a and miR-200b reduced the expression
of amh through site 1 rather than site 2. To explore
the regulatory role of miR-200a in gonadal development,
we further overexpressed miR-200a in the primary
Sertoli cells of the testis. With the overexpression of
miR-200a, the expression of amh decreased, while the
expression of the other two male sex-related genes,
dmrt1 (doublesex and mab-3 related transcription factor
1) and gsdf (diagonal soma driven factor), increased

abstract = "The Beibu Gulf in the northwestern South China Sea is
one of the world's most productive fishing grounds, yet
its biotic resources appear to be in rapid decline
because of overexploitation. Assessments of the health
status of the fisheries' resources in the gulf provide
a foundation for their conservation and management. As
fish accounted for 84\% to 97\% of the total catch in
the Beibu Gulf in the period 1962--2017, a Fish-based
Index of Biotic Integrity (F-IBI) was developed for the
Beibu Gulf, and data from otter trawl surveys during
the period 1962--2017 were used to measure variations
in the fish community. The assessment revealed a
generally downward trend in total fish catch density
(kg/km 2), catch density of 12 traditional commercial
demersal fish species, and percentage of
nektonic-feeding species, but an upward trend for the
percentage of fishes with a planktivorous or detritus
diet, percentage of pelagic species, and percentage of
the dominant species. The dominant species varied
greatly over the 50 year period and showed a tendency
towards small-sized species. The synthetic F-IBI
variable showed a downward trend and has indicated a
`fair' state since 1998. The decline in the F-IBI over
the last three decades suggests that anthropogenic
disturbances, especially overfishing, have had a
serious impact on the fish community of the Beibu Gulf.
The F-IBI is currently at risk of becoming `poor.'
Consequently, we suggest that rigid and enforceable
fishery management measures should be taken by both
China and Vietnam to prevent further deterioration of
the fisheries' resources in the gulf.",

impounded the Upper Peace River to form the Williston
Reservoir in north central British Columbia. In 1990,
an enhancement project was initiated to stock Columbia
River Kokanee (non-anadromous Sockeye Salmon;
Oncorhynchus nerka) from southeastern British Columbia
into tributary streams that drained into regions of the
reservoir that were accessible by anglers. The current
distribution of spawning Columbia-origin Kokanee in the
Williston Reservoir watershed, however, does not
reflect the locations where these fish were initially
stocked and suggests extensive straying. Whether or not
Kokanee will develop fidelity to specific spawning
locations is not known, but it is important information
to effectively manage these introduced fish. We used
otolith microchemistry to estimate fidelity to natal
streams by Columbia-origin Kokanee in the Williston
Reservoir. Otolith elemental signatures for the region
of the otolith that formed during the larval period and
characterized the natal redd environment showed
considerable variation among samples. Natal signatures
tended to cluster for each river but not for all
spawners, suggesting elemental signatures from other
rivers. Homing to one of the four natal streams we
examined was classified to be 73\% based on linear
discriminant analysis, although variation in the
elemental signatures within each group suggests that
homing by Kokanee to specific natal streams may be as
low as 55\%. Based on similarity of water elemental
signatures for tributaries within large rivers,
however, the proportion of fish that returned to their
general region was likely higher and estimated to be
approximately 83\%. The result of regional homing could
be reproductive isolation and adaptation to local
conditions. It is unclear, however, if the current
estimated level of straying will limit genetic
differentiation and prevent local adaptation.",

thousands of otolith or scale images to determine the
age structure of commercial fish stocks. This knowledge
is important for fisheries and conservation management.
However, the age-reading procedure is time-consuming
and costly to perform due to the specialized expertise
and labor needed to identify annual growth zones in
otoliths. Effective automated systems are needed to
increase throughput and reduce cost. DeepOtolith is an
open-source artificial intelligence (AI) platform that
addresses this issue by providing a web system with a
simple interface that automatically estimates fish age
by combining otolith images with convolutional neural
networks (CNNs), a class of deep neural networks that
has been a dominant method in computer vision tasks.
Users can upload otolith image data for selective fish
species, and the platform returns age estimates. The
estimates of multiple images can be exported to conduct
conclusions or further age-related research.
DeepOtolith currently contains classifiers/regressors
for three fish species; however, more species will be
included as related work on ageing will be tested and
published soon. Herein, the architecture and
functionality of the platform are presented. Current
limitations and future directions are also discussed.
Overall, DeepOtolith should be considered as the first
step towards building a community of marine ecologists,
machine learning experts, and stakeholders that will
collaborate to support the conservation of fishery

juvenile crucian carp (Carassius carassius) to a single

evaluated the efficiency of Sr marking of the fish
otoliths (sagittae, asterisci, and lapilli) using an
electron probe micro-analyzer. Sr marking signatures
formed a peak in all otolith types, with a marking
success rate of 100\%. The ratio of Sr to Ca in the
lapilli and sagittae was higher than that in the
asterisci. It took 2 d from the beginning of immersion
to the deposition of Sr on the lapilli and sagittae,
and the time delay for asterisci was 1 d. For the
lapilli and sagittae, it took 16 d to terminate Sr
marking and fully recover to the pre-marking Sr level,
whereas it was 12 d for the asterisci. The application
of the Sr dose had no effect on the survival or growth
of the carp. This study demonstrated that the lapilli
are the most suitable otolith type for Sr marking
observations in crucian carp and provides a theoretical

and the combined effects of climate change, ocean
acidification, and environmental degradation, including
pollution and mangrove overharvesting, could further
reduce global oyster fisheries in the coming decades.
To understand the level of impact of climate change on
the oyster fishery in West Africa, an expert-based
vulnerability assessment to climate change was
conducted for the West African mangrove oyster
(Crassostrea tulipa, Lamarck 1819). Using a combination
of the exposure of the oyster to climatic stressors
(estuarine temperature, salinity, river flow, surface
run-off, sea level rise, and estuarine circulation)
together with an assessment of sensitivity to these
stressors, we estimate the overall vulnerability of C.
tulipa to climate change. A very high overall climate
vulnerability score of 12 on a scale of 16 was
calculated for C. tulipa. While the overall climate
exposure score in the West African coastal region
remained high, the high sensitivity of C. tulipa to
hydrographic conditions of its habitat, in particular
salinity, coupled with its sessile and habitat-specific
nature, pushed the overall vulnerability to very high.
Early life history settlement requirements, adult
mobility, and sensitivity to salinity were the three
most important biological and sensitivity attributes
that determined the vulnerability score. By leaving
each of these three sensitivity attributes out of the
analysis, the overall vulnerability score was reduced
to 9 (i.e., from very high to high). A negative
directional effect of climate change, coupled with a
low potential for change in distribution, threatens the
C. tulipa fishery in a long-term adverse climate
scenario. We recommend management efforts that
incorporate climate resilience and adaptation practices
to prioritize recruitment success, as well as the
development of breeding lines with climate-resilient
traits.",

Understanding the {organism$-$ environment}

which was trained with the georeferenced data of daily

surface temperature, salinity, depth of the mixed

improved glycolysis by increasing PK mRNA levels, while
the 29.28\% and 31.69\% dietary protein levels promoted

proposed study consists of an efficient end-to-end
convolutional neural network (CNN) classifying fish
behavior into the normal and starvation categories. The
performance of the CNN is evaluated by varying the
number of fully connected (FC) layers with or without
applying max-pooling operation. The accuracy of the
detection algorithm is increased by 10\% by
incorporating three FC layers and max pooling
operation. The results demonstrated that the shallow
architecture of the CNN model, which employs a
max-pooling function with more FC layers, exhibits
promising performance and achieves 98\% accuracy. The
presented system is a novel step in laying the

biochemical properties of the crucian carp, a
multi-parameter evaluation method was proposed to
determine the adaptation period of the crucian carp
under this monitoring mode. The results showed that
more than 4 areas were occupied by crucian carp from
the 21st day. From the 16th day, the number of crucian
carp swimming with clear outlines gradually increased.
The number of abnormal swimming occurrences decreased
on day 13. More than 80\% of the crucian carp body
color returned to dark on the 23rd day. The crucian
carp did not respond to food until day 19, when most of
the crucian carp began to scramble for food. Food
consumption reached more than two thirds on day 22. In
addition, glucose and total protein leveled off after
day 21, when mean hemoglobin levels were highest.
Triglycerides showed a trend of first decreasing and
then increasing. The pigmented area of the skin section
gradually decreases and eventually stabilizes. In
summary, it takes at least 23 days for the crucian carp
to adapt to the influence of the bionic robot fish.",

expected that behavioural differences at the larval

wild-caught zebrafish for boldness, using an open field

we studied larvae at the age of 5-, 7-, 12- and 30-days

behavioural development, clearly differed between the
larvae of the different strains. Wild larvae showed
larger total distance moved than AB larvae, both at
light and dark conditions. These differences were
already present at 12 dpf but became more pronounced
with age. Wild larvae had a greater variance compared
to AB larvae for most of the variables. We have
previously shown that bold and shy adult zebrafish
differ in the brain expression of dopamine and opioid

wild larvae display significantly higher brain

Understanding how the crossover between warming and
zooplankton availability impacts fish populations has
paramount implications for conservation and mitigation
strategies. Through a cross factorial design to test
the effects of ocean temperature and food availability
in a temperate marine teleost, Pomatochistus
flavescens, we showed that hindered feeding impacted
sheltering and avoidance behaviour. Also, low food
availability impaired fish reproduction, particularly
male reproduction, as the expression of cyp11b1, a gene
with a pivotal role in the synthesis of the most
important fish androgen, 11-ketotestosterone, was
significantly reduced under a low food regime. In
contrast, temperature alone did not affect reproductive
success, but offspring showed increased saturated fatty
acid content (embryos) and increased lipid peroxidation
(larvae). Altogether, food availability had a stronger
effect on fitness, showing that coping with elevated
temperatures, an ability that may be expected in
shallow-water fish, can be indirectly impacted, or even
overwhelmed, by the effects of ocean warming on primary

relationships with climatic and environmental
parameters. We first conducted a Spearman correlation
analysis to identify the differences in the SDR between
sites. Then, we used Generalized Additive Models to
evaluate the effects of external forcing at multiple
spatial scales (i.e., local and global scales) on the
anchovy catches recorded at the California Current
Ecosystem (CCE), Humboldt Current Ecosystem (HCE), and
Kuroshio Current Ecosystem (KCE). We found that the
SDRs at different sites in the same Current Systems are
generally consistent, while there are more differences
between different systems. We also found that the
Pacific Decadal Oscillation index (PDOI), North Pacific
index (NPI), North Pacific Gyre Oscillation index
(NPGOI), Sea Surface Temperature anomaly (SSTA), and
Air Temperature anomaly (ATA) were the most influential
factors explaining the variability in anchovy catch for
CCE, whereas the NPGOI was the most influential factor
for HCE. The PDOI was the best at explaining the
variability in anchovy catch for KCE. Our results
suggest that anchovy fluctuations in the Pan-Pacific
occurred synchronously. These seemingly unrelated
events, which occurred thousands of kilometers apart,
were actually not isolated. Therefore, we suggest that
large-scale climate forcing may activate synchronous
fluctuations for anchovy populations at the basin
scale, whereas local-scale environmental forces are
also responsible for anchovy fluctuations in the

abstract = "Fish represent an excellent source of animal protein
as well as a biomedical research model as a result of
their evolutionary relatedness and similarity with the
human genome. Commercial and ornamental fish culture
has achieved popularity, but reproductive dysfunctions
act as a limiting factor for quality fry production,
interfering with the sustainability of the aquaculture
industry. Fish reproduction is crucial for any species'
existence, and reproductive performance can potentially
be improved through applications of epigenetics and
probiotics. Epigenetics is a highly sensitive molecular
approach that includes chromatin structure and function
alteration, DNA methylation, and modification of
non-coding RNA molecules for the transfer of desired
information from parents to offspring. DNA
methyltransferase improves reproductive cyp11a1, esr2b,
and figla gene expression and feminizes zebrafish
(Danio rerio). Moreover, epigenetics also contributes
to genome stability, environmental plasticity, and
embryonic development. However, methylation of specific
genes can negatively affect sperm quality, resulting in
poor fertilization. Probiotic administration is able to
induce responsiveness of incompetent follicles to
maturation-inducing hormones and can change oocyte
chemical composition during vitellogenic development.
The positive role of probiotics on testicular cells is
validated by upregulating the transcription levels of
leptin, bdnf, and dmrt1 genes facilitating the
spermatogenesis. This review not only discusses the
effects and mechanism of epigenetics and probiotics for
improving fish reproduction, but also presents an
overview of the causal factors and current techniques
used to eradicate dysfunction. Moreover, key genes and
hormones related to fish reproduction along with
research gaps and future prospects are also considered.
This review provides an overview of necessary
information for students, scientists, researchers, and
breeders to resolve fish reproduction-related problems
to ensure profitable and sustainable aquaculture.",

respectively, and no squid were older than 10 months.
The peak hatching dates, according to back

year. All sampled squid belonged to the autumn/winter
cohort. Significant sex differences were found in the
relationship between ML and age in squid with similar
growth patterns. Exponential models best described the
relationships of ML with age and body weight (BW) for
both sexes. However, a linear model best described the
relationship between age and upper rostrum length
(URL). The maximum absolute daily growth rates (AGR) of
BW were reached during days 240--270 for both sexes.
The maximum AGRs in ML were reached during days
180--210 and 240--270 for males and females,

GVC participation has become the most important
platform for addressing gains from trade in developing

participation enhances economic growth. Recent studies
on GVC participation in developing countries have
highlighted the importance of domestic institutions.
However, the literature is silent on the quality of the

the Hausman--Taylor (HT) estimator and the system

potential drives backward GVC participation, while low
forward participation might not only lead to lower
gains from trade, but also limit countries to the
supply of primary seafood products with little value
addition. In addition, the quality of domestic
institutional governance constrains GVC participation.
Overall the results indicate that the quality of

the most heavily exploited sharks, being the main
by-catch species in both tuna longline and purse-seine
fisheries in tropical waters worldwide. Despite this
severe exploitation, little is known about the species'
life history and population status. Silky sharks, like
many other sharks, exhibit slow growth and low
fecundity, indicating the urgency of developing
assessment studies to aid in the implementation of
conservation plans for their stocks. Because
information on the catch and effort of this species is
scarce, some length-based data-limited methods were
applied in the present study to provide estimates of
the status of the tropical Pacific silky shark
population. As evident from the LBSPR analysis, the
current spawning potential ratio (SPR) was found to be
below the target reference point of SPR 40\% and
slightly above the limit reference point of SPR 20\%.
In addition, the LBB model also confirmed that this
stock's status is overfished with relatively low
biomass levels. Furthermore, both models showed
estimates of size selectivity at 50\% and 95\% that
were lower than the estimated size at sexual maturity.
In conclusion, the data-limited models developed in
this study indicated that the silky shark stock in the
tropical Pacific Ocean may be at risk of further
decline. Additionally, the results show that growth and
recruitment overfishing may be occurring in the silky
shark's population calling for immediate
intensification of monitoring programs for these sharks
as a pre-requisite to develop efficient management and

identification methods. With the rapid development of
deep learning, the application of computer vision in
agriculture and farming to achieve agricultural
intelligence has become a current research hotspot. We
explored the use of facial recognition in fish. We
collected and produced a fish identification dataset
with 3412 images and a fish object detection dataset
with 2320 images. A rotating box is proposed to detect
fish, which avoids the problem where the traditional
object detection produces a large number of redundant
regions and affects the recognition accuracy. A self-SE
module and a fish face recognition network (FFRNet) are
proposed to implement the fish face identification
task. The experiments proved that our model has an
accuracy rate of over 90\% and an FPS of 200.",

potential marine resource in the open South China Sea
(SCS). However, little is known about the spatial and
temporal distribution of its habitat, and how this may
respond to environmental changes. Using fish survey and
remote sensing data from 2015--2019, we applied
generalized additive models to identify relationships
between environmental factors and the distribution of
A. thazard in the SCS. To examine seasonal patterns in
the habitat of A. thazard in the SCS, we generated a
habitat suitability index model using environmental
factors screened by generalized additive models.
Results showed that A. thazard migrates from south to
north in the SCS, and its suitable habitat is patchily
distributed. Significant environmental factors
affecting the habitat of A. thazard distribution were
different in different seasons; we demonstrated A.
thazard to be sensitive to Chl-a in spring (optimum
0.155, optimal range $ \approx $0.1252--0.1840), and in
summer to be sensitive to SST (optimum 30.405, optimal
range $ \approx $29.789--31.021) and SSH (optimum
0.741, optimal range $ \approx $0.618--0.864). Suitable
habitat in spring occurs mainly in northeastern areas,
while in summer it occurs mainly around the
southeastern Nansha Islands. Compared with that in
spring, the area of suitable habitat increases in
summer, as does the habitat suitability index of the
entire sea area. These results improve our
understanding of environmental factors that affect the
distribution of A. thazard habitat in the SCS, and
provide a scientific basis for the development and
management of A. thazard resources.",

fish, rohu carp, Labeo rohita, in Bangladesh. Fish fry
with an average weight of 387.5 {\pm} 169.25 mg and an
average length of 3.35 {\pm} 0.37 cm were collected
from a local hatchery in Mymensingh, Bangladesh and
acclimatized for a week in the Department of Fisheries,
University of Dhaka before starting the exposure with
arsenic. Fishes were exposed for a period of 14 days
with three treatments of NaAsO 2, namely treatment
1(T1)---2.5 mg/L; treatment 2 (T2)---15 mg/L; and
treatment 3 (T3)---30 mg/L, along with a control
(C)---0.0 mg/L, with three replicates. These
concentrations were determined based on the LC 50 value
for 96 h measured for this experiment. This study
revealed remarkable morphological abnormalities and
deformities in arsenic-exposed rohu carp. In fish
exposed to 30 mg/L, caudal fin erosion was a frequent
deformity. There was no significant difference in
RNA:DNA ratio among the treatments. The overall weight
of fish was decreased as the concentration of arsenic
was increased. The T3 fish had a statistically
significant negative weight gain ({$-$0}.05 {\pm} 0.07
g), but the other treatments (T1 and T2) and control
fish had no significant weight gain. Different types of
histopathological changes were observed in the gills
and intestines of arsenic-treated fish. Necrosis and
severe damages were found in the secondary lamellae of
gills at the highest arsenic concentration (30 mg/L).
Epithelial lifting, irregular shape and damages in the
gill raker were also observed in the primary lamellae
of the gills for the same treatment. In this study, the
expression of heat shock protein (HSP 60) and
metallothionein (MT) genes was assessed by qPCR, and
these genes were upregulated in different treatments
compared to controls. The findings of the present study
suggest that arsenic pollution significantly changes
the morphology, behavior, growth, development,

abstract = "Ivory shell (\bioname{Babylonia areolata}) is a
commercially important aquaculture species mainly found
on the southeast coast of China. However, it has been
greatly affected by vibriosis in recent years. In this
study, FP17 (a potential pathogen) was isolated from a
dying ivory shell with ``acute death syndrome'' and
confirmed as a pathogen via infectious experiment.
Furthermore, phylogenetic analysis based on the average
nucleotide identity (ANI) sequencing of the 16S rRNA
gene and housekeeping genes (\gene{ftsz}, \gene{gapA},
\gene{gyrB}, \gene{mreB}, \gene{pyrH}, \gene{rpoA}, and
\gene{topA}) indicated that FP17 was identical to
Vibrio tubiashii. Transmission electron microscopy
showed that FP17 is curved and has a short rod shape,
with a single flagellum. Besides, the calculated LD 50
after the intramuscular injection of FP17 was 2.11 $
\times $ 10 6 CFU/g at 14 d. The genome of the FP17
strain consists of two chromosomes and one plasmid with
5,261,336 bp and 45.08\% GC content, including 4824
open reading frames (ORFs) and 150 non-coding RNAs
(\gene{ncRNA}). Genome mining revealed that 120
candidate gene clusters, including vibrioferrin and
flagellum-related proteins, are responsible for
virulence. Comparative genomic analysis showed that
vibrioferrin genes, such as pvs and type
\SGMLentity{8549} secretion system protein genes
(\gene{vas}), are specific in \bioname{V. tubiashii}
FP17 but not in the ATCC19109 strain. Furthermore, 92
antimicrobial resistance (AMR) genes, such as
\gene{tufA}, \gene{tet(35)}, \gene{crp}, etc., were
mapped within the genome as the potential candidate for
virulence, consistent with antibiotic susceptibility
assay. This is the first study to describe the complete
genome sequence of \bioname{V. tubiashii} infecting
ivory shell. The genetic characteristics, virulence
factors, and antimicrobial resistance of the
\bioname{V. tubiashii} strain FP17 were also
explored.",

abstract = "Most of world's fish and seafood are produced by
aquaculture, which is one of the biggest contributors
to the world's food security. The substantial increase
in prices of conventional feed ingredients and the
over-exploitation of natural resources are some of the
biggest constraints to aquaculture production. To
overcome this stress, different approaches and
techniques are used, among which the use of
non-conventional feed ingredients in the aquaculture
sector is the most recent approach. Different
non-conventional feed ingredients such as plant-based
products, algae (both micro and macroalgae),
single-cell protein (bacteria and yeast), and insect
meal are currently used in aquaculture for sustainable
food production. Amongst all these novel ingredients,
insects have greater potential to replace fishmeal. The
existence of about 1.3 billion tons of food and
agriculture waste from the food chain supply poses a
serious environmental threat. Insects are tiny
creatures that can thrive on organic waste and thus can
convert the waste to wealth by the bioconversion and
nutritional upcycling of organic waste. Insects have
the potential to recover nutrients from waste
aquaculture products, and many fish species feed on
insects naturally. Therefore, employing insects in the
aquaculture sector to replace fishmeal is an
eco-friendly approach. The present review briefly
highlights emerging non-conventional feed ingredients,
with special attention given to insects. The current
review also focuses on the nutritional value of
insects, factors affecting the nutritional value of
insects, potential insects that can be employed in the
aquaculture sector, the physiological response of fish
when fed with insect meal, techno-functional properties
of insect meal, and emerging approaches for addressing
possible downsides of employing insect meal in fish
diets. Finally, it suggests avenues for further
research into these inventive fishmeal replacements.",

for non-lethal biomonitoring has recently commenced.
Fish scales have been shown to incorporate cortisol
over longer periods of time than blood and thus provide
a promising means of assessing long-term stress in many
species of teleost fish. However, while cortisol is a
major mediator of the stress response in fishes,
downstream effects of chronic stress on reproduction
can involve gonadal steroids such as progesterone and
testosterone. The quantification of these additional
hormones alongside cortisol could therefore allow for
the assessment of both stress and consequential
reproductive alterations. To investigate these
concepts, we artificially elevated circulating
cortisol, progesterone, and testosterone in rainbow
trout (\bioname{Oncorhynchus mykiss}) using coconut oil
implants for three weeks. Following this we quantified
these three hormones as well as 11-ketotestosterone, a
potent androgen in teleost fishes. In all cases serum
samples reflected a significant increase in the
injected hormone confirming the efficacy of this
method; however, this did not result in significantly
elevated scale concentrations of the same hormone in
all cases. As the stress and reproductive axes are
closely integrated, these findings are likely a result
of interactions along the steroidogenic pathway
indicating that a further investigation of the
relationship between scale concentrations of these
hormones and actual physiological processes is
required. Nevertheless, the successful quantification
of both stress and gonadal steroid hormones within the
scale suggests that such measurements could provide a
novel and informative tool in the assessment of
long-term stress and the resulting effects on
reproductive endocrinology in teleost fishes.",

abstract = "The Antarctic continent is one of the most pristine
environments on planet Earth, yet one of the most
fragile and susceptible to the effects of the ongoing
climate change. The overwhelming majority of the
components of Antarctic marine trophic chain are
stenotherm organisms, highly adapted to the extreme,
but extremely stable, freezing temperatures of the
Antarctic ocean, which have not changed significantly
during the past fifteen million years. Notothenioid
fishes are the most abundant representatives of
ichthyofauna at these latitudes, being ubiquitously
found in coastal areas across the entire continent.
While different Antarctic fish species have been
previously subjected to studies aimed at defining their
range of thermal tolerance, or at studying the response
to acute thermal stress, just a handful of authors have
investigated the effects of the exposure to a moderate
increase of temperature, falling within the expected
forecasts for the next few decades in some areas of the
Antarctica. Here, the emerald rockcod Trematomus
bernacchii was used as a model species to investigate
the effects of a 20-day long exposure to a +1.5
{$^\circ $} C increase in the brain, gills and skeletal
muscle, using a RNA-sequencing approach. In parallel,
the experimental design also allowed for assessing the
impact of stabling (including acclimation, the handling
of fishes and their confinement in tanks during the
experimental phase) on gene expression profiling. The
results of this study clearly identified the brain as
the most susceptible tissue to heat stress, with
evidence of a time-dependent response dominated by an
alteration of immune response, protein synthesis and
folding, and energy metabolism-related genes. While the
gills displayed smaller but still significant
alterations, the skeletal muscle was completely
unaffected by the experimental conditions. The stabling
conditions also had an important impact on gene
expression profiles in the brain, suggesting the
presence of significant alterations of the fish nervous
system, possibly due to the confinement to tanks with
limited water volume and of the restricted possibility
of movement. Besides providing novel insights in the
molecular mechanisms underlying thermal stress in
notothenioids, these findings suggest that more
attention should be dedicated to an improved design of
the experiments carried out on Antarctic organism, due
to their extreme susceptibility to the slightest
environmental alterations.",

used to extract the background, fish body, pectoral
fin, and caudal fin. In the subsequent step, the
segmentations obtained from the best network were used
for calculating body length (BL) and body width (BW).
These parameters were employed for estimating the
injection position. The proposed Atten-Deeplabv3+
achieved the best segmentation results for intersection
over union (IoU) on the test set, with 99.3, 96.5,
85.8, and 91.7 percent for background, fish body,
pectoral fin, and caudal fin, respectively. On this
basis, the estimation error of the injection position
was 0.2 mm--4.4 mm, which is almost within the
allowable injection area. In conclusion, the devised
method was able to correctly differentiate the fish
body from the background and fins, meaning that the
extracted area could be successfully used for the
estimation of injection position.",

one of the high-income-generating carangid fish species
and the only known member of its genus. This study aims
to identify existing gaps in stock status and
population demography of this species and provide
viable management recommendations to enhance the
sustainability of this fishery. Therefore, three
methodological approaches have been used in this study;
TropFishR to present the current exploitation status,
the length-based spawning potential ratio (LB-SPR) to
quantify stock spawning biomass, and Froese's
sustainability indicators (LBI) to establish a basic
standard for sustainable management of the fishery. In
the length--weight relationship of black pomfret, an
allometric growth pattern ($ b = 2.19$) was found. The
VBGF life history parameters for black pomfret were L
{\infty} = 55.25 cm, K = 0.54 year {$-$1}, and based on
LCCC analysis, the total mortality ($ Z = 1.61$ year -
1), natural mortality ($ M = 0.69$ year - 1) and
fishing mortality ($ F = 0.91$ year -1) are calculated.
The result reveals that this fishery is currently
suffering from overexploitation and the stock's
spawning biomass (SPR = 13\%) is below the limit
reference point because most of the catch (82\%) was
found to be under the maturity level. Based on the
results, this study recommended strictly maintaining
the mesh size of the net to ensure not to catch
immature fish with a length smaller than 30.63 cm,
recommended the length to catch be between 29 and 35
cm, and reducing fishing pressure by one-third to
ensure the sustainability of the black pomfret
fishery.",

Here, we addressed the Wallacean shortfall for
freshwater fish faunas across Europe by using the
completeness indicator derived from species
accumulation curves to quantify the fish sampling
efforts. The multiple potential drivers of completeness
that were previously related to the sampling efforts
for other species (i.e., population density, nature
reserves, or distance to cities) were tested using a 10
$ \times $ 10 km 2 grid resolution, as well as
environmental (e.g., climatic) factors. Our results
suggested that although there was an overall spatial
pattern at the European level, the completeness was
highly country-dependent. Accessibility parameters
explained the sampling efforts, as for other taxa.
Likewise, climate factors were related to survey
completeness, possibly pointing to the river conditions
required for fish sampling. The survey effort map we
provide can be used to optimize future sampling, aiming
at filling the data gaps in undersampled regions like
the eastern European countries, as well as to account
for the current bias in any ecological modeling using

However, at the juvenile stage, the specific growth

regime in the seas and oceans of our planet. The
mitochondrial complex of nuclear erythrocytes of
cartilaginous fish, as the energy basis of blood cells,
has repeatedly encountered such climatic fluctuations
throughout their evolutionary history. In this regard,
the features of the adaptive strategy of the
erythrocyte mitochondrial complex in the thornback ray
(\bioname{Raja clavata} {L.}) are of interest from the
evolutionary and ecological points of view. The rate of
oxygen consumption in resuspended (Ht = 25--30\%)
erythrocytes taken from the Black Sea thornback ray in
saline was studied by the polarographic method. A high
``basal'' rate of respiration in the erythrocytes of
the thornback ray was shown, which ranged from 10.5 to
21.6 pmol O 2 min {$-$1} {\cdot}10 6 cells. The
addition of substrates of the mitochondrial respiration
activators glutamate, maleate, and succinate to the
erythrocyte suspension caused a 2--6-fold increase in
the respiratory activity of thornback ray erythrocytes.
In cases where the rate of respiration of erythrocytes
was high, protonophore--dinitrophenol caused an
inhibition of the activity of mitochondrial
respiration. At low respiration rates of erythrocytes,
its effect was opposite and caused a stimulation of
mitochondrial respiration. Oligomycin caused a
significant inhibition of the respiratory activity of
the red blood cell suspension of the thornback ray.
This suppression of cell respiration was enhanced under
conditions of exposure to the permeabilization of
erythrocytes with digitonin. This can be recommended as
one of the ways to block the respiratory activity of
erythrocytes in cartilaginous fish. Another way of
effectively blocking the respiration of the
mitochondrial complex of the thornback ray's
erythrocytes was the effect of the blockers rotenone
and sodium azide. The peculiarity of the mitochondria
of the erythrocytes of the thornback ray was the
absence of the complete inhibition of respiration by
sodium azide (NaN 3), which is characteristic of the
mitochondria of other fish species. Our data on the
activation of the ``respiration'' of erythrocytes in
fish indicate that the potential capabilities of
cold-blooded and warm-blooded vertebrates have rather
similar characteristics. This may indicate the initial
``laying'' of the architecture of the inner membrane to
support the energy potential of the mitochondria of the

growth model, maximum mouth opening, daily survival,
and starvation period were determined. The larval
growth was fastest during the first 24 h {post$-$
hatching} (HPH) at 28 {\pm} 1 {$^\circ $}C with an
average increase of 625.42 $ \mu $ m in total length
and 573.51 $ \mu $ m in standard length. The highest
percentage of yolk absorption (52\%) occurred within 24
HPH and at 96 HPH the yolk sac was completely
reabsorbed. The PNR was reached at 156.41 HPH ($ p <
0.05$). At 96 HPH, the upper and lower jaw were
distinguishable by mouth movements. Our results suggest
that the larvae of {$ D. l a t i f r o n s$} should be
fed at 96 HPH with prey measuring 50--65 $ \mu $ m.",

that the Eh-HSP 10 and Eh-HSP 40 genes were expressed
in different normal tissues, with the highest

appropriate concentration of strontium might have
positive effect for T. obscurus. The strontium to
calcium (Sr / Ca) ratios of otoliths in the marked

time, which were higher than the baseline,

Unfortunately, there is no established method to detect

immunoassay method for viral detection using a
single-chain variable fragment (scFv), a specific
region of IgG antibodies that binds specifically to KHV
particles. The results of functional analyses indicated
that four putative scFv candidates, C5, F8, F6, and E4,
were specific to KHV, but only F6 and C5 had a high
binding affinity. The binding characteristics were
confirmed by indirect competitive and sandwich
enzyme-linked immunosorbent assays, which indicated
that F6 and C5 have a broad penetration area to the
binding region and share a similar epitope with
commercial KHV monoclonal antibodies. These
characteristics were further confirmed by their
interactions with purified KHV coat protein by indirect
ELISA and Western blot analyses. In conclusion, the F6

abstract = "Abundance indices are essential data for the
application of stock assessment models to obtain fish
abundance estimates. Abundance indices have usually
been derived from fishery-dependent data, yet the
increase in fisheries-independent surveys is now
offering new opportunities for these calculations. In
this study, we explored the usefulness of
ichthyoplankton indices derived from scientific surveys
in estimating spawning biomass. In addition, we also
investigated whether the strength of the year--class of
the commercial cohort of Atlantic hake, as a
determinant, could be defined at an early life stage.
We used samples collected during the triennial mackerel
and horse mackerel egg surveys (MEGS), which cover the
hake spawning area in the Bay of Biscay. The biomass
indices were determined as the abundance of eggs in the
early development stage (stage 1) when transformed into
egg production (EP) from 1995 to 2019 in the months of
March and April---which is considered a period of high
spawning activity for hake in this area. Additionally,
we built a metric for larval abundance and converted
larval length into age. This was in addition to
constructing a pre-recruit year-class index (YCI) while
using the EVHOE bottom trawl abundance database for
hake for the period of 1997 to 2016. The results of
regression analysis of egg production and spawning
stock biomass indicate that both parameters are
significantly correlated (r = 0.76). By connecting the
abundance of eggs and larvae in the adjoining stages,
we are able to identify two periods of high mortality
associated with the transition from ``yolk-sac-first''
to ``feeding larvae'' and ``late larvae-YCI10'', but we
were unable to discover when the strength of the
recruitment year--class is determined. As such, it
appears that for the northern stock of hake,
recruitment is established in the late juvenile
stages.",

(0.12--0.33 g/100 g) varied during the study period.
Seasonal fluctuations in seawater temperature and pH

degrees of food deprivation. The activities of lactate

time of E. sinensis initially decreased and then
increased, whereas the proportion of searching and

There was a significant difference in the probability
of capture upon encountering; however, food deprivation
did not significantly affect the probability of
consumption upon capture. Under food deprivation, the
proportion of E. sinensis crushing tactics after
nine-day food deprivation was significantly lower than
that in the first nine days. Lactate dehydrogenase
activity in the E. sinensis hepatopancreas after food
deprivation was significantly higher than that in those

conclusion, different degrees of food deprivation

(0.2 -- 0.35 m g / m 3), and warm water ($ > 20^\circ

based on pigment signatures, and the isotope signatures
of seagrass and red mangrove leaf tissue (enriched
{\delta} 15 N values) and consumers (depleted {\delta}
15 N values). Food web mixing models based on stable
isotopes ({\delta} 13 C and {\delta} 15 N) revealed
that multiple producers (phytoplankton, benthic
microalgae, seagrasses, etc.) contributed organic
matter to the consumers (zooplankton, invertebrates,
and fishes) in the MSP seascape at the center of the
reserve. Contribution estimates for common benthic
invertebrates (crabs and shrimp) were taxon-specific,
and the highest input was generally linked to
particulate organic matter (POM) and benthic microalgae
(BMA)/seagrass producer categories, although meaningful
mangrove contribution was observed for some taxa.
Similarly, contribution estimates for fishes were
highest for POM and BMA/seagrass, with the latter
producer category being more important for species
known to migrate from mangroves or patch reefs to
seagrass beds at night (bluestriped grunt, French
grunt, and white grunt). Although all fish investigated
were observed in mangrove prop-root habitats, input of
organic matter from mangroves to these consumers was
typically limited for most of the species examined.

round goby abundance and distribution is still not well

samples were analyzed by both droplet digital PCR
(ddPCR) and quantitative PCR (qPCR) to maximize the
likelihood of detection. Overall, round goby was

methods detected round goby in 74\% and 66\% of samples

More studies comparing eDNA based methods to

the disputed maritime areas causes significant damage
to the marine ecology and authorized fisheries,

often inadequate in these areas. In light, this study
aims to clarify the regulatory obligations of relevant
states and explore feasible solutions based on
international cooperation to promote IUU governance in
disputed areas worldwide. The rapidly evolving
international fisheries legal framework requires that
states, such as coastal states, flag states, port

obligations to prevent and deter IUU and that the
presence of disputes in a specific maritime area does
not typically constitute grounds for derogation from
these obligations or exemption from possible state

conflicting claims in disputed maritime areas should be
taken into consideration while interpreting and
applying international legal rules. Therefore, this
study suggests that regional and inter-regional
cooperation is necessary for states to fulfill their
obligations to regulate IUU fishing and prevent state
responsibilities under international law. Parties to
the dispute, as well as third parties, are encouraged
to participate in the cooperative mechanism in order to
coordinate legislative and enforcement measures and
advance the institutionalization of IUU fishing
regulation in the disputed maritime areas, which will
not only advances the effective governance of IUU

characterizing the levels of genetic diversity among

an important species of cultured marine fish with high
economic value in China. Nevertheless, from May to
November 2019, mass mortality among cultured Japanese
seabass occurred in Zhuhai City, Guangdong Province of
China. Approximately 0.2--0.5\% mortality was recorded
daily, and the cumulative mortality was up to 30\%
during this disease outbreak. In this study, the
clinical signs and pathological characteristics of
diseased fish were investigated. Furthermore, the
pathogenicity and antibiotic sensitivity of identified
pathogenic bacteria from diseased fish were analyzed.
The infected fish showed clinical signs of
uncoordinated swimming; anorexia; pigment changes; and
a number of 1--5 mm grayish-white nodules in the liver,
spleen, and kidney tissues was also found. A bacterial
strain, which was designated as ZHLJ2019, was isolated
from the diseased fish. To ensure that ZHLJ2019 isolate
was the causative agent, a Koch postulate trial was
performed. Healthy Japanese seabass were infected by
the intraperitoneal injection of 5 $ \times $ 10 4, 5 $
\times $ 10 5 and 5 $ \times $ 10 6 CFU/fish, and
cumulative mortalities within 42 days were 75\%, 90\%,

traditional morphological and biochemical
characteristics similar to that of Mycobacterium

rpoB, hsp65, erp, and ITS genes confirmed that the
isolated strain ZHLJ2019 was M. marinum. The
granulomatous inflammation in internal organs of

significantly lower in the intestinal samples. Although
the relative abundances of Proteobacteria and
Cyanobacteria were high in all samples, three phyla
(Bacteroidetes, Gemmatimonadetes, and Latescibacteria)

in Russia and Ukraine to support respective large-scale
fisheries of jack mackerel in this region. We reviewed
these studies that documented long-term seasonal and
interannual variability of the STF from sea surface
temperature (SST) and sea surface height (SSH) data. We
also mapped the STF from satellite sea surface salinity
(SSS) data of the SMOS mission (2012--2019). The
Subtropical Front consists of two fronts--North and
South STF about 500 km apart--that border the
Subtropical Frontal Zone (STFZ) in-between. The STF is
density-compensated, with spatially divergent
manifestations in temperature and salinity. In the
temperature field, the STF extends in the WNW to ESE
direction in the Southeast Pacific. In the salinity
field, the STFZ appears as a broad frontal zone,
extending zonally across the entire South Pacific.
Three major types of satellite data-SST, SSH, and
SSS-can be used to locate the STF. The SSH data is most
advantageous with regard to the jack mackerel
fisheries, owing to the all-weather capability of
satellite altimetry and the radical improvement of the
spatial resolution of SSH data in the near future.
Despite the dearth of dedicated in situ studies of the
South Pacific STFZ, there is a broad consensus
regarding the STFZ being the principal spawning and
nursing ground of T. murphyi and a migration corridor
between Chile and New Zealand. Major data/knowledge
gaps are identified, and key next steps are proposed to
mitigate the data/knowledge gaps and inform fisheries

indicate that RPL4 and GNB2L1, and EEF1A and HPRT1 were
the most appropriate reference genes for the pituitary
and ovary of S. argus, respectively, in the three
developmental stages of the ovary. Additionally, GeNorm
analysis suggested that for the accurate normalization
of gene expression, two reference genes were reliable
in the ovary and pituitary of S. argus. To the best of
our knowledge and understanding, this is the first
study to identify appropriate reference genes for
analyzing gene expression in S. argus. Consequently,
this study can be used as a foundation for future
research on the reproduction of S. argus.",

for many ichthyologic studies focusing on morphological
and colour variation. The bright lateral spots---a part
of the mimicry of this fish---cause a taxonomic puzzle.
Common practice is that morphometric and molecular
studies lack habitat assessments of species originating
from different environments. In this study, we analysed
body shape and colour variation within two species of
Sabanejewia in order to reveal whether they are more
affected by phylogeny or environmental conditions. The
environmental parameters were obtained using satellite
mapping tools, body shape using geometric morphometry,
and the molecular identification of specimens using an
analysis of mitochondrial DNA (sequence of the
cytochrome b gene). Generalized linear mixed models
were used for the analysis of lateral spot numbers, and
principal components analysis to describe the changes
in landmark position defined by the permutation tests.
Results show a significant impact of the locality
elevation and specimen's sex on the change of the body
shape. We identified significant differences in the
number of lateral spots, which are considered mimicry
variation across an elevation gradient. Morphological
differences of Sabanejewia spp. vary with ecological
factors along the river continuum.",

the aquaculture industry emphasize environmental
sustainability more than those in the other industries
do. Likewise, firms in the aquaculture industry
emphasize social sustainability more than those in the
other industries do, but the difference is less marked.
Across industries, knowledge-intensive firms emphasize
environmental sustainability and social sustainability
to a lesser extent. Additionally, firms with local or
regional major ownership emphasize social
sustainability more than those with international major
ownership do. Conclusion: Firms in the aquaculture
industry have a relatively strong emphasis on
environmental and social sustainability, which may be
due to the industry's environmental challenges.
Similarly, aquaculture firms have a relatively strong

waleckii (LwAqps) genome and analyzed its
transcriptional expression profile and genetic
evolution under carbonate alkalinity stress. A total of
18 Aqp genes were identified in four grades in L.
waleckii. The highest Aqp gene expression was found in
the gill and kidney of L. waleckii from the Wusuli
River (WSL) in comparison to those in the Dali Lake
(DL), whereas aqp3a, -3ap1, -7, and -9a expressions
were found at intensively higher levels in the gill
rather than in the kidneys and livers. The experiment
of L. waleckii under alkalinity stress (carbonate
alkalinity 50 mmol{\cdot}L {-1}) and its recovery
showed that the expressions of aqp0a, -3a, -3ap1, -7,
-8aa, and -9a were upregulated in alkaline water and
downregulated in freshwater. We identified 1460 single
nucleotide polymorphism (SNP) markers in the Aqp genes.
The average value of Fst of SNP markers in the CDS
region was 0.177 {\pm} 0.256, and the first 5\% SNPs
were identified at aqp3a and -11b. Residue Ser66 does
not bring about an overall change in the
three-dimensional structure of Aqp3a, but may change
the penetration of solutes across the membrane. This
indicates that Aqp genes are involved in the response
of L. waleckii to alkaline stress, and aqp3a is one of
the key genes involved in regulating L. waleckii 's
adaptation to alkaline environments.",

Canyon, a biodiversity hotspot. Reproductive
characteristics of Pseudecheneis sulcatus, including
their maturation age, fertility, spawning season, and
maximum body size, constitute important aspects of its
life-history traits. We collected a total of 310
specimens from the Yarlung Zangbo River's Motuo reach
between March and November 2016 and found the
male-to-female ratio to be 0.73:1, markedly different
from the anticipated 1:1. The total length of
individuals ranged from 72 to 207 mm, while overall
weight ranged from 2.5 to 65.0 g. Their length at first
maturity was estimated as 131 mm in males and 132 mm in
females. Based on the adult proportion and fluctuation
in the monthly gonadosomatic index (GSI) and size
distribution of oocytes, spawning was determined to
occur from March to June. The absolute fecundity ranged
between 247 and 2886 eggs, while the fluctuation in
average relative fertility ranged between 16.8 and 77.1
eggs/g of fish. The fecundity of P. sulcatus was
linearly correlated to the overall weight and length of
the fish along with the ovarian weight. In conclusion,
P. sulcatus spawned synchronously in spring and early
summer, exhibiting low fecundity and large oocytes. Our
results provided basic information in understanding how
this species adapted well to the unique canyon
environment, which may be useful for developing a
sustainable conservation plan for P. sulcatus at the

iso-nitrogenous) with different levels of {\beta}-1,3
GF (0, 0.5, 1.0, and 1.5 g kg {-1}) were fed to healthy
shrimp juveniles weighing 3 {\pm} 0.5 g for 75 days.
Shrimps were randomly distributed into 12 net

However, there were no substantial variations in the

Surprisingly, all antioxidants (superoxide dismutase,
catalase, glutathione peroxidase) and immune biomarkers

elevated with increasing levels of {\beta}-1,3 GF in
the shrimp diet, and the highest values were recorded

showed a typical black to brown gill lesion similar to
that observed in the natural infection, where an
identical fungus was successfully re-isolated from

sustainable food, playing a key role in achieving
nutrition security, employment, and Blue Growth. This
is particularly true in geographical areas where the
dependence of local economies on fishery products is
high and yet access to sustainable landings is hindered
by environmental drawbacks. One such area is
represented by the Black Sea, which offers different
degrees of suitability for aquaculture development.
While the southern and eastern shores are sheltered
enough to allow for the development of large
aquaculture activities, the north-western shoreline is
characterized by wide environmental fluctuations and
the strong influence of the Danube. This study aimed at
investigating the suitability of a selected area of the
Romanian coast (Mangalia) for finfish cage farming by
adapting an internationally endorsed methodology for
determining its Degree of Compatibility (DC). The
development and expansion of finfish aquaculture
depends on the availability of space, so designating
Allocated Zones for Aquaculture (AZAs) is essential.
The result obtained (DC = 80) indicates that the
Mangalia area is suitable for finfish aquaculture
activities: there is no major interference with other
uses of the maritime space, no conflicts with nature
conservation, and the environmental conditions are
appropriate for fish culture in floating cages. The
novel information provided by this study can be the
building block for authorities to settle the governance
gap that has so far impeded the development of marine
aquaculture in Romania. At a larger scale, this study
can serve as a good practice example at the regional

This study is the first to document the successful sex

study the physiological status of potential biosensor
shellfish species and to monitor freshwater and marine
systems: valvometry (registration of gaping activity in
bivalve mollusks) and photoplethysmography
(registration of cardiac activity in mollusks and
crustaceans). Valve movement responses to stressors
such as abnormal conditions and pollutants include the
closure of shell valves for a long period, decrease in
the average distance between valves, rapid shell
opening, and higher closing frequency. Cardiac activity
reactions of shellfish to stress factors include rapid
increases in heart rate and stress index, higher
variability in heart rate than under normal conditions,
and longer periods required for heart rate recovery
after stress. The most common bioindicators used to
monitor environmental disturbances in marine ecosystems
are blue mussels, Iceland scallops, and red king crabs
in cold-water habitats and Black Sea mussels in warmer
waters as well as freshwater mussels and crayfish in

In this study, the use of otolith morphometrics and
shape analysis were explored to delineate the redfin
species under the genus Decapterus from the Sulu Sea,
Philippines, namely, Decapterus kurroides, D.
smithvanizi, and D. tabl. Results showed that the mean
otolith shapes are unique within species (p {$<$}

OL---otolith length, OH---otolith height, OA---otolith
area, and OP---otolith perimeter) and shape-related
(RE---rectangularity, SQ---squareness,
EL---ellipticity, RO---roundness, AR---aspect ratio,
FF---form factor, CO---compactness, and
CI---circularity) morphometric indices also showed
significant variations (p {$<$} 0.001) among the three
species. Distinct regions differentiating D. kurroides
from the other two species were seen along the dorsal
margin of the otoliths, which was supported by its
significantly higher values for OH (size-related index)
and RO (shape-related index). In addition, the
morphometric indices showed significant variations (p
{$<$} 0.001), except for RE. Furthermore, it was
revealed that the size-related indices were able to
separate D. kurroides from the other two species, which
turned out to be indifferent. The results provided
relevant data on the use of otoliths as an additional
confirmatory tool in species delineation of the
identified redfin species, and, therefore, offer
opportunities of applying the same method in
delineation and, eventually, identification of species
from other genera, especially those that closely

unigenes with an N50 of 2008 bp and an average length
of 1144 bp were obtained from the sequencing raw data

candidate pathways related to gonadal development,
including insulin synthesis, oocyte maturation, and
steroid biosynthesis, which were involved in biological
processes such as regulation of hormone metabolism, sex
cell proliferation and development, and amino acid
metabolism. The DEGs related to the above pathways such
as insulin-like growth factor 1 receptor (IGF1R), heat
shock protein 90 (Hsp 90), and cyclooxygenase (COX)
genes were highly expressed during yolk protein
synthesis, indicating that these genes might be
involved in yolk accumulation and oogenesis. Meanwhile,
calmodulin (CaM) and other genes were highly expressed
during spermatogenesis, suggesting that these genes
might play an important role in spermatogenesis. Ten
differentially expressed genes in the KEGG signaling
pathway, including CRQ, COX, APP, Cdc42, Hsd17b12,
Art-1, Hsp70, Hsp90, PRMT1, and GP, were selected for
real-time quantitative PCR (RT- qPCR) to validate the

protein sources to replace traditional fisheries and
plant ingredients. Using agriculture by-products as
protein sources would reduce land-based feed production
pressure and waste production, promoting a circular
economy and sustainable aquaculture. Distiller's dried
grains with solubles (DDGS) is the main by-product of
bioethanol production. Corn DDGS has a high protein
level, but its high fiber content limits its use as a
feed ingredient, particularly for carnivorous fish.
Solid-state fermentation (SSF) uses
lignocellulosic-rich substrates, such as DDGS, for
microbial growth in the near absence of water,
promoting enzyme production that degrades the
lignocellulosic matrix, increasing free reducing
sugars, protein, and antioxidant levels of the
substrate. In the present work, the SSF of corn DDGS
with Aspergillus carbonarius, A. ibericus, and A.
uvarum was tested. Then, the digestibility of the most
promising fermented DDGS (in terms of upgraded
nutritional composition) was tested by including it in
a reference diet (70\% of a reference diet; 48\% crude
protein; 15\% crude lipids) for European seabass
(Dicentrarchus labrax) juveniles (171 g averaged
weight; trial duration of 52 days). Among the fungi
tested, Aspergillus ibericus led a generally higher
upgrading of the DDGS nutritional composition, leading
to a high amount of protein (from 42.7 to 49.7 g N/kg
DM), phenolic compounds (1.49 to 4.86 mg/g caffeic acid
equivalents), free sugars (9.5 to 31.9 mg/g), and
enzyme production (45 U/g and 68 U/g of cellulase and
xylanase, respectively), and a high reduction in acid
detergent fiber and neutral detergent fiber content (up
to 29 and 43\%, respectively). Compared to the
unfermented DDGS, fermented DDGS presented increased
protein, lipids, starch, and energy digestibility,
while phosphorous digestibility was similar. Compared
to the reference diet, dietary inclusion of unfermented
or fermented DDGS increased trypsin and chymotrypsin
activities. The activity of digestive enzymes was not
affected by the inclusion of fermented DDGS, except for
amylase activity, which was lower with the fermented
DDGS than with the unfermented DDGS diet. In
conclusion, SSF of DDGS enhanced its nutritional value,
increasing DDGS digestibility when included in diets
for European seabass juveniles.",

one of the best predictors for numerous life history

ecology, we illustrate the potential of bioimpedance
spectroscopy, as opposed to single frequency
measurement, for experimental studies on fish. Using a
monolithic four-contact electrode and a cost-effective
portable system, we conducted bioimpedance spectroscopy
on 159 sardines. The association between the length,
weight, and electrical parameters obtained at different

vertebrate. This study compares the light organ
ultrastructure of D. licha with that of Etmopterus

deeper understanding of the light emission process and
its evolutionary conservation within shark families.
The ultrastructure of D. licha 's photophores and the
morphological changes that occur after hormonal
stimulation (via melatonin and \alpha -MSH, which
stimulate or inhibit the bioluminescence, respectively)
were examined. The photophores consist of a spherical
pigmented sheath surrounding a unique, regionalized
light-emitting cell (photocyte). The photocyte's basal
area contains a specific area filled with granular
inclusions that resemble the glowon-type microsources
of E. spinax, suggesting that this area is the
intracellular site of light emission. An acidophilic
secretion, not present in Etmopteridae, is also
observed within the granular area and may be involved
in photogenesis. The ultrastructure analysis reveals no
lens cells or reticular layer, unlike in Etmopteridae
photophores, indicating a simpler organization in
Dalatiidae photophores. Melatonin stimulation causes
the removal of pigments from the photophore-associated
melanophores and an increase in the granular inclusion
diameter and coverage in the granular area, further
showing that this last area is the potential site of
light emission, while \alpha -MSH stimulation causes
the extension of the melanophore pigments and a
decrease in the granular inclusion diameter and
coverage. These results support the evolutive

partitioning has recently been suggested as a mechanism

temporal partitioning. In this study, we used acoustic

examined the differences between the two species

maximum depth of 7.5 m, we found both species perform a
diel vertical movement, rising closer to the surface at
night and moving deeper during daytime. Furthermore,
the two shark species swam at different depths both day
and night, with C. obscurus swimming in the upper
column, about 2 m shallower than C. plumbeus. The very
small scale of movement, which nearly equals the

characteristics of blood in the capillary blood flow is
one of indicator of fishes' adaptation for the changing
temperature conditions. Our earlier studies showed that
large, nucleated erythrocytes of the Black Sea
thornback ray (Raja clavata L.) and scorpionfish
(Scorpaena porcus L.) had high ecto-ATPase activity.
This activity varied from 3.0 to 3.9 and 6.0 to 10.0
nmol Fn/min/$ \mu $L RBC in rays and scorpionfish,
respectively. The use of thermal energy of ATP in the
hydrolysis process made by ecto-ATPases in fish
erythrocytes provided a heating of the plasma cells'
membrane and the near-wall plasma layer with an aim to
improve the rheological characteristics of blood in the
capillary blood flow. To confirm the proposed
assumption, we studied thermal phenomena in
erythrocytes suspensions of fishes by continuous
recording of temperature changes in the experimental
cell with fishes' erythrocytes suspension with the
addition of ATP (1 mg/mL) in vitro. A higher
``thermal'' activity of scorpionfish erythrocytes was
established in comparison with erythrocytes of the
thornback ray, which had the multiplicity of activity
of ecto-ATPase in the plasma membranes of erythrocytes
of the studied fishes. The presence of heat-producing
activity of suspensions of erythrocytes of thornback
ray and scorpionfish is evidence of the possible use of
thermal energy of ATP hydrolysis by fish erythrocytes,
both to maintain the functional state of the plasma
membrane of red blood cells and to improve the
rheological characteristics of blood in the capillary
section of blood flow.",

abstract = "Chub mackerel (Scomber japonicus) is a major targeted
species in the Northwest Pacific Ocean, fished by
China, Japan, and Russia, and predominantly captured
with purse seine fishing gear. A formal stock
assessment of Chub mackerel in the region has yet to be
implemented by the managing authority, that is, the
North Pacific Fisheries Commission (NPFC). This study
aims to provide a wider choice of potential models for
the stock assessment of Chub mackerel in the Northwest
Pacific using available data provided by members of the
NPFC. The five models tested in the present study are
CMSY, BSM, SPiCT, JABBA, and JABBA-Select. Furthermore,
the influence of different data types and input
parameters on the performance of the different models
used was evaluated. These effects for each model are
catch time series for CMSY, catch time series and prior
of the relative biomass for BSM, prior information for
SPiCT, and selectivity coefficients for JABBA-Select.
Catch and CPUE (catch per unit effort) data used are
derived from NPFC, while some life history information
is referred from other references. The results indicate
that Chub mackerel stock might be slightly overfished,
as indicated by CMSY (B 2020 / B MSY = 0.98, F 2020 / F
MSY = 1.12), BSM (B 2020 / B MSY = 0.97, F 2020 / F MSY
= 1.21), and the base case run for the JABBA-Select (SB
2020 / SB MSY = 0.99, H 2020 / H MSY = 0.99) models.
The results of the models SPiCT (B 2020 / B MSY = 2.30,
F 2020 / F MSY = 0.31) and JABBA (B 2020 / B MSY =
1.40, F 2020 / F MSY = 0.62) showed that the state of
this stock may be healthy. Changes in the catch time
series did not affect CMSY results but did affect BSM.
The present study confirms that prior information for
BSM and SPiCT models is very important in order to
obtain reliable results on the stock status. The
results of JABBA-Select showed that different
selectivity coefficients can affect the stock status of
a species, as observed in the present study. Based on
the optimistic stock status indicated by the best
model, JABBA, a higher catch is allowable, but further
projection is required for specific catch limit
setting. Results suggested that, as a precautionary
measure, management would be directed towards
maintaining or slightly reducing the fishing effort for
the sustainable harvest of this fish stock, while
laying more emphasis on accurately estimating prior
input parameters for use in assessment models.",

at 0.25\degree and 0.5\degree spatial scales was
greater than 0.8. The AUC values each month based on
the FE data at a 1\degree scale ranged from 0.775 to

at the 1\degree scale were comparable to the model

temperature (SST), temperature at 100 metres (T100),
oxygen concentration at 100 metres (O100) and total
primary production (PP) had the greatest influence on
the distribution of the purse seine tuna fleet. The
oxygen concentration at 200 metres (O200), distance to
shore (DSH), dissolved oxygen (Dox), EKE, mixed layer
depth (Mld), sea surface salinity (SSS), salinity at
100 metres (S100) and salinity at 200 metres (S200) had

had little influence. The suitable habitat areas varied
in response to environmental conditions. The purse
seine tuna fleet was mostly present at locations where

27--29 \degree C, 150--200 mmol/m 3 and 5--10 mg/m

developed for zebrafish (Danio rerio) to examine
anxiety-like behavioral responses. Among them, the
novel tank diving test is rapidly gaining popularity in
translational neuroscience and behavioral research for
the investigation of psychopharmacological activity
focusing on stress. Zebrafish respond to conspecific
epidermal-released alarm substances with antipredator
reactions. Although the alarm responses of zebrafish
were well characterized in a novel tank diving
experiment, the relationship between the intensity of
the alarm behavior and the concentration of the alarm
substance needed to be understood more adequately. In
the current paper, we investigated the behavioral
phenotypes and potencies of zebrafish elicited by the
serial dilution of an alarm substance in the novel tank
diving test. Using a video-tracking assisted behavioral
quantification approach, we demonstrated no linear
concentration-dependent relationship between
antipredator behavior and skin extracts, suggesting
that an optimal concentration induced each typical
behavioral response. The results showed that the
freezing duration (\%) significantly increased when
stimulated with 10 4 -fold times dilutions of skin
extract (equivalent 5 $ \times $ 10 \minus 5 fish/L),
while erratic movements (\%), time in the bottom half
(\%), and latency to the upper half (s) significantly
elevated when stimulated with 10 3 -fold times
dilutions (equivalent 5 $ \times $ 10 \minus 4 fish/L).
Therefore, the concentration threshold for an alarm
substance that elicited innate fear behavior in
zebrafish was presumed to be an equivalent
concentration of approximately 5 $ \times $ 10 \minus 4
fish/L. The conclusions may fill a knowledge gap
between the innate fear response triggered by injured
skin and a novel tank diving paradigm that provides
insights into the characterization of alarm substance,

Jinshaia sinensis is a typical small and endemic but

mitochondrial genes (the cytochrome-c oxidase subunit
I, COI, and cytochrome-b gene, Cytb) and two nuclear
genes (recombination-activating protein 1, RAG1, and
rhodopsin, RH). The genetic diversity analysis
indicated that J. sinensis had high genetic diversity,
with high haplotype diversity (h) and nucleotide
diversity (Pi). Population pairwise F ST analysis
revealed a significant genetic divergence between the
Lijiang and Luzhou populations for all genes and
between the Panzhihua and Luzhou populations, except
for the COI gene; however, analyses of molecular

analysis also indicated a certain degree of gene
exchange among populations. Haplotype network structure
analyses revealed low levels of shared haplotypes among
populations. Neutrality test and mismatch distribution
results indicated that only the Lijiang population had
experienced obvious population expansion. Overall,
these results indicate that J. sinensis is still a

Plasma cortisol, glucose, and selected transcripts

responses significantly differed between stressed and

The transcript concentrations of most genes remained

lutea, Diacronema lutheri, Chaetoceros neogracile, and
Thalassiosira weissflogii) were fed for 6 weeks; the
growth, survival, and fatty acid profiles of post-set
clams were evaluated. Clams fed equal proportions of T.
lutea, D. lutheri, C. neogracile, and T. weissflogii
had higher growth, while those fed equal proportions of
T. lutea and C. neogracile had higher survival. The
poorest-performing diet consisted solely of diatoms. A
contrasting polyunsaturated fatty acid (PUFA) profile
was found in post-set clams fed flagellate- or
diatom-only diets. Clams fed the bi-algal flagellate
diet had a higher percentage of docosahexaenoic acid
(DHA) but a lower percentage of (n-6) PUFA, whereas
those fed the bi-algal diatom diet had a higher
percentage of arachidonic acid (ARA) and
eicosapentaenoic acid (EPA) but a lower percentage of
DHA. The percentages were similar and neither very high
nor very low in clams fed the remaining dietary
treatments. The results of this study show that sunray
venus post-set clams can be successfully produced when
fed a typical hard clam bi-algal flagellate and diatom
diet, but they indicate that growth may be accelerated
by the addition of other microalgae species.",

the period 2001--2020, this study applies the threshold
panel data model of Hansen (2000) to empirically
explore the nonlinear relations between the number of
fishing vessels, fishers, and fishery production, with
distinct overfishing stocks (overfishing) and fish
caught by trawling or dredging techniques (trawling) as
the threshold variables. Our findings show that the
levels of fishery outputs could be increased by
different combinations of primary factors, such as the
number of fishing vessels and fishers. More
specifically, when the number of fishing vessels and
fishermen operating in countries with a high ratio of
overfishing (overfishing {$>$} 4.4456) increased, their
fishery outputs significantly increased as compared
with countries with a low percentage of overfishing. As
overfishing activities increase, they can result in
significant shortages and imbalances of fishery
resources, directly influencing fish biomass,
biodiversity, and sustainability of fisheries, as well
as making destructive fishing practices worse for
marine ecosystems. Countries with a relatively high
proportion of trawler net usage (trawling {$>$} 4.5516)
would have significantly lower fishery outputs, as more
fishing vessels are invested in them, compared with
countries with a low proportion of trawling net use.
This implies that trawler net usage is a
non-sustainable fishing technique and harms fishery
resources. The policy implications of this study
indicate that taxing overfished species and
implementing trawling regulations could significantly
improve species richness and site-based abundance, thus
helping to sustain fishery outputs.",

Mediterranean Sea. The number of recreational fishers
is growing, and they are using increasingly efficient
fishing techniques. However, fisher activity is
heterogeneous, both temporally and spatially, making it
very difficult to determine this sector's fishing
pressure and annual yields. Therefore, estimates of
annual yields and ecological effects of this fishing
sector are limited. In this study, we undertook an
extensive survey designed to document and quantify
recreational fishing patterns across the Israeli
Mediterranean shoreline. We comprehensively quantified
recreational fishing using three complementary
strategies: (1) ground surveys, including interviews
with anglers on the coast, (2) personalized phone
interviews, and (3) aerial surveys by helicopter. These
methods were used to calculate annual recreational
yield and to estimate species and size composition,
which were then compared to the commercial fishing
catch. We found that a recreational catch makes up
between 10\%-37\% of the total annual fishing yields,
which is similar to estimates from other regions of the
Mediterranean. We also found that non-indigenous
species are among the most common species in
recreational catch and have become a significant part
of local fishery yields. Recreational angling from the
coast targets smaller, reef associated species compared
to recreational fishers at sea. We identified 23
species common to both recreational fishing and
commercial fishing, over which conflicts between
fishing sectors may arise. These results can be used to
more accurately manage Israeli fisheries and can
provide a baseline against which to compare future

Manila clam Ruditapes philippinarum is a species of
marine bivalve with important economic value. A new
C-type lectin (Rpcl) from the clam was obtained and its
potential role in feeding and feed selection was
studied. Rpcl cDNA was 929 bp in length and had 720 bp
of open reading frame. Rpcl encoded 235 amino acids,
comprising a carbohydrate recognition domain (CRD) as
well as an N-terminal signal peptide. Rpcl contained a
conserved CRD disulfide bond including five cysteine
residues (Cys 125, Cys 142, Cys 213, Cys 219, and Cys
237) and the QPN motif (GLN 204 -PRO 205 -ASN 206).
Phylogenetic analysis revealed that the amino acid
sequence of Rpcl was closely related to that of
Vpclec-1 from R. philippinarum and C-type lectin from
Mercenaria. The qPCR analysis indicated that Rpcl
expression was observed in all examined tissues and was
the highest in gills followed by in the hepatopancreas,
and to a lesser extent in the mantle and lip. The in
vitro agglutination experiments showed that, the
purified Rpcl protein could selectively agglutinate
with different microalgae. The strongest agglutinating
effect with Chlorella sp. was observed, followed by
Karlodinium veneficum and Chaetoceros debilis Cleve. No
agglutination with Prorocentrum minimum was observed.
In the feeding experiment, compared with that of the
starvation group, Rpcl expression in the lip and gill
of the clam fed with C. debilis and K. veneficum showed
a significant upward trend with the change of time. In
addition, it was found that the changes in the

main feeding tissues, were consistent with the slope of
the decrease in the number of algal cells in the water

pathogens inflict increasing economic losses to
fisheries and aquaculture, while also posing a growing
risk to public health and affected species
conservation. In this study, four wild marine fish
species were collected at five fishing sites in Israel,
divided into two regions --- north (Acre, Haifa,
Shefayim) and center-south (Tel-Aviv and Ashdod), and
screened for Photobacterium damselae. An initial
screening was carried out using PCR analysis with
specifically designed primers on DNA extracted from
livers and kidneys. P. damselae -positive samples had
their 16S rRNA amplicons sequenced. Later, an attempt
to specify relevant sub-species was performed, using a
three-layered gene screen: Car, ureC and toxR. Of 334
fish samples, 47 (14\%) were found to be P. damselae
-positive, of which 20 were identified as P. damselae
subsp. piscicida (Phdp), two as P. damselae subsp.
damselae (Phdd) and 25 could not be identified to
subspecies. Our results strengthen the view that fish
residing in a polluted environment are receptive of
pathogenic microorganisms. To assess how the presence
of pathogens may affect population management and
conservation, this research should be followed by
studies aimed at: (i) quantifying levels of pollutants
that may affect pathogen emergence, and (ii) creating a
standard pollution-level index as a basis for setting
criteria, above which authorities should take measures
of precaution.",

Ghrelin, pyya, and pyyb mRNAs were highly expressed in

relatively high an hour post-feeding and decreased
after 3 to 72 h of fasting. The glp - 1 mRNA expression
was increased after 6 to 24 h of fasting. The pyya mRNA
expression was increased after 72 h of fasting, while
the pyyb expression remained stable during fasting. The
diet with 14\% lipid promoted the expressions of glp-1,
pyya, and pyyb, but inhibited the ghrelin expression.
The ghrelin expression in the intestine was increased

strategies that can effectively reduce fish mortality

images and low-identification targets present great
challenges to diseased fish detection. To overcome
these challenges, this paper proposes a diseased fish
detection model, using an improved YOLOV5 network for
aquaculture (DFYOLO). The specific implementation
methods are as follows: (1) the C3 structure is used
instead of the CSPNet structure of the YOLOV5 model to
facilitate the industrial deployment of the algorithm;
(2) all the 3 $ \times $ 3 convolutional kernels in the
backbone network are replaced by a convolutional kernel
group consisting of parallel 3 $ \times $ 3, 1 $ \times
$ 3 and 3 $ \times $ 1 convolutional kernels; and (3)
the convolutional block attention module is added to
the YOLOV5 algorithm. Experimental results in a fishing
ground showed that the DFYOLO is better than that of
the original YOLOV5 network, and the average precision
was improved from 94.52\% to 99.38\% (when the
intersection over union is 0.5), for an increase of
4.86\%. Therefore, the DFYOLO network can effectively
detect diseased fish and is applicable in intensive

abstract = "Fish biomass and stock assessment are estimated from
acoustic volume backscattering strengths (Sv) obtained
from various hydroacoustic equipment. Although sound
attenuation due to fish schools and water influences
the Sv value, only attenuation from water is considered
during the acoustic data process. For these reasons, it
is necessary to understand the characteristics of sound
attenuation by fish. Unfortunately, little is known
about sound attenuation from fish. In the present
study, the attenuation from one to four fish specimens
was precisely measured during ex situ experiments in a
water tank. The scientific echo sounder of a split-beam
200 kHz transducer and a miniature hydrophone were used
for the attenuation measurements. Results show that the
maximum attenuation coefficient ({\alpha}) was
approximately 25 dB/cm when the 4 multiple fishes had
high fish heights. The relationship between the
attenuation coefficient ({\alpha}200kHz) and the total
fish height (Htotal) was approximately
{\alpha}200kHz=0.54{\ast}Htotal {\pm}$ \approx $0.06
(r2=0.72). This work describes the sound attenuation
characteristics to provide basic information for the
compensation of Sv from fish schools or layers.",

studied using specimens captured between March 2010 and
March 2012 as by-catch in the shrimp trawl fishery off
the coast of the state of Pernambuco, Brazil. A total
of 347 vertebrae were read, 161 from males
(81.6--249.55 mm) and 186 from females (86.15--298.1
mm). The estimated average percentage index (IAPE)
ranged from 0.71\% to 4.33\% (mean = 2.5\%) in
vertebrae from specimens with 1 and 6 band pairs,
respectively. In the present study, the different
approaches to validation produced variable results
(partially valid growth zones). We then decided to
discuss the growth of the species considering the
formation of an annual ring. There were statistically
significant differences in growth between the sexes.
The best model to describe male growth was the von
Bertalanffy growth model for two phases (VBGM TP) with
growth parameters L {\infty} (maximum theoretical
length) = 230.35 mm, k (growth constant) = 1.00, t 0
(theoretical age of size zero) = {-0}.76 years and for
females it was the von Bertalanffy with birth size
(VBGM L 0) model with parameters L {\infty} = 282.55
mm, k = 0.37. The age of maturity for males and females
was 1.52 and 2.02 years, respectively, and the maximum
age observed was 5.5 and 8.5 years, respectively.
Despite being a fast-growing species, Urotrygon
microphthalmum is threatened, probably due to the high
mortality levels from shrimp trawling in a very narrow
range of the shelf where all the life stages are
captured.",

Sexual behavior was recorded in fish from these embryos

behaviors, as in other vertebrates. In the autism
model, the patterns of sexual behavior are present but
with significant modifications. The behavior of males
was the most affected, while in females, the most
affected parameter was oviposition. These results show
that, in the autism model of zebrafish, sexual behavior

in contrast to the growth of global tilapia production
that contributes to the volume of seafood imports into
the U.S. A national survey (coverage rate = 75\% of
tilapia sold; response rate = 18\%) found that on-farm
regulatory costs accounted for 15\% of total production
costs on U.S. tilapia farms, the fifth-highest cost of
production. The total direct regulatory costs
nationally were \$4.4 million, averaging
\$137,611/farm. Most problematic were regulations of
effluent discharge, predatory bird control,
international export, and water and energy policies.
Manpower costs for monitoring and reporting were the
greatest cost of regulatory compliance. The lost sales
revenue resulting from regulations was \$32 million a
year, or 82\% of total annual sales, indicating that
the regulatory framework has constrained the growth of
U.S. tilapia farming. The smallest tilapia farms had
the greatest regulatory cost per kg. This study
provides evidence that regulatory costs, along with
other challenges related to live fish markets, have
contributed to the decline in U.S. tilapia production.
Increased competitiveness of the U.S. tilapia industry
will require a combination of: (1) improved regulatory
efficiency that reduces on-farm cost burdens without
reducing societal benefits; (2) research and on-farm
extension assistance to evaluate new tilapia fillet
equipment; and (3) research on changing consumer

evaluated the time required for anesthesia induction

exposed to the essential oils of Aloysia triphylla
(EOAT) and Lippia alba (EOLA), and their major
compounds citral and linalool, respectively. In
addition, we evaluated the locomotor activity of
amphipods using ANY-maze {\reg} software. Mortalities
were observed at concentrations of 100 and 200
{\SGMLmicro}L/L of citral (50.0 {\pm} 0.39\%) and 750
{\SGMLmicro}L/L of EOLA (66.7 {\pm} 0.33\%). Except for
linalool, increased concentrations of the compounds of
the essential oils decreased the time for sedation and
anesthesia induction. There were differences for the
induction of anesthesia (p {$<$} 0.05) and recovery (p
{$<$} 0.05) between EOLA and linalool treatments, but
not between that for EOAT and citral. Reduced locomotor
activity and longer time and episodes of freezing were
observed in animals exposed to EOAT. The EOs and their
major compounds induced anesthesia and affected the
locomotor activity of H. bonariensis, Therefore, EOAT
and linalool are recommended for anesthesia of this
species. EOAT can also be utilized in long-term
exposure.",

threat to the potential growth of the economy of
penaeid culture, which is still controlled by the
administration of antibiotics. At first, the infected
group was subjected to phenotypic bacteriological
examination with subsequent molecular identification
via 16S rRNA gene sequencing, which confirmed four
strains of Vibrio spp., V. atlanticus, V. natriegens,
V. alginolyticus, and V. harveyi, from
moribund-infected shrimp during mortality events in an
Egyptian hatchery. To better understand the defense
mechanism of the most effective antibiotic against
Vibrio strains, the immune responses were compared and
evaluated in infected Litopenaeus vannamei broodstock
after being fed 5 mg kg {-1} of florfenicol antibiotic,
which was first determined through in vitro antibiogram
tests. Therefore, our study aimed to determine the
immune response of L. vannamei during Vibrio spp.
infection in Egyptian hatcheries and after antibiotic
medication. The parameters assessed were the total and
differential hemocyte count (THC), granular cells (GC),
semi-granular cells (SGC), and hyaline cells (HC). As
well as the metabolic and immune enzymes: alanine
aminotransferases (ALT), aspartate aminotransferases
(AST), alkaline phosphatase (ALP), acid phosphatase
(ACP), and lysozyme activity; an antioxidant index,
such as superoxide dismutase (SOD) and glutathione
(GSH); a phagocytic assay; changes in reactive oxygen
species (ROS); and bactericidal activity in the
hemolymph of the control, infected, and treated groups.
Further evaluation of the mRNA expression levels of the
prophenoloxidase (LvproPO), toll-like receptor 1
(LvToll1), and haemocyanin (LvHc) genes were performed
in the hepatopancreas of the same groups. A significant
drop in the THC, GC, SGC, and HC counts, as well as
lysozyme and bactericidal activities, phagocytic assay,
ROS, SOD, and GSH index, were represented in infected
shrimp compared to control shrimp; however, a marked
increase in the activity of ALT, AST, ALP, and ACP was
observed. These activities were significantly restored
in the treated shrimp compared to the infected shrimp.
Nevertheless, no significant changes were noted in the
transcriptional levels of the LvproPO and LvToll1 genes
in the treated shrimp when compared to the infected
shrimp; however, a significant suppression of the LvHc
gene was noted. Our study aimed to determine the immune
response of L. vannamei during Vibrio spp. infection in
Egyptian hatcheries and after antibiotic medication. We
concluded that florfenicol in medicated feed could be
effective in controlling vibriosis and ameliorating the

hydrolysis of protein into smaller peptide and free
amino acids, which has recently captured considerable
attention as a supplementary ingredient in the
aqua-feed industry sector. The present research aimed
to observe the physiological, biochemical, and
bacteriological study of FPH-treated diets and its
effects on growth, hematology, plasma biochemistry,
liver and gut histopathology, and resistance to
Aeromonas hydrophila infection in Pabda (Ompok pabda).
Four experimental diets (35\% crude protein) were
formulated with graded FPH supplementation (0, 0.5, 1,
and 2\%). The feed physiological parameters such as
expansion ratio, bulk density, water stability, and
floatability were not significantly affected by dietary
FPH levels (p {$>$} 0.05), except for the pellet
durability index (PDI). Furthermore, the diets with 1\%
and 2\% FPH were more palatable to fish than other
treatment diets. The total bacteria (TB) in fish diets
and guts followed an increasing trend with the increase
in various levels of FPH in diets. The significantly
highest body weight, specific growth rate (SGR), total
biomass (TB), survival rate (SR), condition factor
(CF), and hepatosomatic index (HSI) were noted in 2\%
FPH-fed fish when compared with other treatment groups
(p {$<$} 0.05). The feed intake of fish was
significantly increased when increasing the FPH in
diets (p {$<$} 0.05). The fish fed with a 2\% FPH diet
had significantly higher neutrophil, monocyte,
lymphocyte, red blood cell, and platelet levels (p
{$<$} 0.05). The blood glucose, creatinine, total
protein, and globulin were significantly lower in
control fish compared to other treatment groups (p
{$<$} 0.05). The histopathological observation of mid
intestine tissues displayed that 2\% of FPH-diet-fed
fish had a well-anchored epithelial wall with
well-arranged goblet cells, a long villus structure,
stratum compactum, and tunica muscularis compared to
other treatments of FPH. The inclusion of FPH in diets
up to 2\% significantly improved the liver health of
fish. The fish fed with 2\% FPH had a significantly
lower cumulative percent mortality (16.67\%) against A.
hydrophila infection in the bacterial challenge test (p
{$<$} 0.05). Therefore, the present results suggested
that using 2\% FPH in the aqua-feed industry improves
the growth performance, health status, and disease
resistance of Pabda fingerlings in captivity.",

mechanism behind the accumulation of lipids in the

unknown. This study conducted a comparative
transcriptome analysis of the ovaries of mud crabs at
various stages of ovarian maturation. A total of 63.69
Gb of clean data was obtained, with a Q30 of 93.34\%,
and 81,893 unigenes were identified, including 10,996
differentially expressed genes (DEGs). After KEGG
enrichment of these DEGs, MAPK signaling pathway was
significantly enriched during vitellogenesis. Moreover,
the expression levels of genes involved in
carbohydrate, amino acid, and lipid metabolism were
found to be higher during vitellogenesis. The two genes
(Sp-Eip75B and Sp-Eip78C) that are homologous to the
vertebrate gene PPAR{\gamma} in the PPAR signaling
pathway, were identified. Additionally, genes in MAPK
signaling pathway might regulate lipid metabolism
through PPAR signaling pathway based on Protein-Protein

suggest that the flesh quality of farmed fish was
improved by short-term stocking in natural water. To
elucidate the reasons of flesh quality change in the
stocked group, this study compared the food composition
and intestinal digestive enzyme activity in three
groups, demonstrating that the ranched and stocked
groups had similar food composition, with their
detritus proportion lower than that of the farmed
group, consuming easily digestible phytoplankton
diatoms rich in amino acids and fatty acids. No
significant difference was seen between the ranched

This study aimed to assess the potential role of
dietary tryptophan supplementation in meagre juveniles
in order to minimize the deleterious effect of
potential stress conditions. For this, a growth trial
was performed wherein meagre juveniles were fed four
isoproteic (45\%DM) and isolipidic (16\%DM) diets;
namely, a control diet, and three diets similar to the
control diet but supplemented with varying levels of
tryptophan, graded according to the resulting
percentage in each diet's dry matter (Control,
0.25\%Trp, 0.5\%Trp, and 1\%Trp), corresponding to a
total dietary tryptophan of 1.06, 1.70, 2.08, and 3.24

growth trial, a time-course blood sampling was
performed at 0 h, 1 h, 3 h, 6 h, and 12 h after

supplementation (total dietary Trp 3.24 g 16 g {-1} N)
may be harmful to fish, decreasing growth performance

not influence these parameters. Voluntary feed intake
lineally decreased with the increase in the level of
dietary Trp. Whole-body lipid content decreased at the
highest tryptophan inclusion, whereas no changes were
observed in protein levels. After 12 h from feeding,
plasma glucose levels were lower in all dietary
treatments supplemented with tryptophan compared to
those observed in the control. Hepatic enzyme activity
of protein catabolism decreased with dietary Trp
inclusion. Overall, our results suggested that while a
dietary Trp level increase of up to 2.08 g 16 g {-1} N
did not affect growth performance and feed efficiency,
both these parameters were severely compromised with a

samples collected with at least 30 samples sampled from
each pond system in the zone. The morphometric data
generated were analyzed using multivariate analysis. In
order to delineate the populations from the different
ponds, Discriminant Function analysis (DFA) was
performed on the dataset and distribution plots
generated to test on the purity of the strains. There
were significant differences in the morphometric traits
among the populations with the Victoria fish population
having the highest standard length while the Kyoga
population had the highest weight. Morphometric
characterization grouped the fish into three clusters,
indicative that fish farms in the zone possibly had
different sources of fish seed. The condition factor,
which is a measure of wellbeing of the fish, showed
that all the populations displayed an isometric growth
which is indicative of the fish growing in length as it
is in weight. The results of this study provide
evidence that local O. niloticus from different farms
display differences in body shape as a result of using
fish seed from different sources. This aspect can be
applied in selective breeding programs after
establishing the genetic structure of the farmed Nile
tilapia stock.",

personnel who collect, enter, or use freshwater

purposes. The survey's primary objective was to
evaluate the program at its 15-year mark; secondary
objectives were to compare results with a similar
survey conducted at the 4-year mark, compare results
among respondents based on experience and functional
role, and develop recommendations for strategic
initiatives to further improve the program. The survey
consisted of 43 questions across six sections of
program evaluation: demographics; field sampling; data
entry, summary, and reporting; management decision
support; programmatic views; and additional input.
Respondents generally had positive views of the LTM
program, but the survey revealed differences among
respondents with different functional roles (e.g.,
fisheries researchers and managers viewed the
decisional value, priority, and sample sizes of LTM
data more favorably than habitat managers) while
highlighting high-priority future initiatives (e.g.,
database development). Our results demonstrate the

minimize variability among compared populations make 3N
trout an informative system to test hypotheses about
fitness consequences of fish locomotion. Here, we ask
if reduced survival of 3N relative to 2N trout in
natural ecosystems during periods of high temperature
relate to a lower aerobic swimming capacity and aerobic
scope of 3N compared with 2N conspecifics. Three-yearly
cohorts of conspecific 2N and 3N hatchery-reared,
yearling rainbow trout were ranked for swimming
endurance, externally marked for their endurance
quantile, and then stocked into two lakes as yearlings
to quantify their survival in the wild over summer as a
function of ploidy, temperature and endurance; all
while tracking temperature and depth habitat
utilization via telemetry. As expected, 3N swimming
endurance was lower than that of 2N, but with
considerable individual overlap. Aerobic swimming
endurance, especially for 3N, was predictive of summer
survival in a warm lake where piscivorous birds
potentially exerted high predation pressure, resulting
in low fish survival. This empirical evidence of a

provides support for long held assumptions of this

aquaculture, given it prepares the fish for a
successful transit from fresh to seawater. However,
industry players have not yet reached a consensus on
the best protocols to produce high-quality smolts. In
this study, we assessed how the combination of two
photoperiod regimes in freshwater (continuous light or
LL, and natural photoperiod or LDN) and four transfer
times to seawater (February, March, April, and May)
affected smolt development and their subsequent growth
in seawater until slaughter during commercial
production. The results demonstrated that
smoltification and growth in freshwater were only
slightly modulated by the photoperiod treatment and
were instead much more affected by the limiting effect
of the low water temperature during that period. In
seawater, the growth rate was the highest in the same
groups, which had, however, experienced a delay in
growth when in freshwater, and consequently, no
differences in the final body weight between the eight
treatments were found. Such compensatory growth in the
sea was probably enhanced by the increasing smolt
quality, which could allow for better performance in
seawater. A significant link between the weight at
slaughter and weight at transfer was observed only in
the groups with a lower smolt quality (LL-Feb, LDN-Feb
and LDN-Mar), which suggests that larger individuals
could cope better with a saline environment. In
contrast, smaller smolts probably suffered greater
osmotic stress that hindered their performance at sea.
Afterwards, as smolt quality increased in the
subsequent transfer groups, the relevance of this size
effect decreased. This means that the industry may
benefit from transferring larger smolts to seawater,
especially if these are suspected of having developed
suboptimal seawater tolerance. Those individuals are
likely to cope better with saline conditions than
smaller smolts. Future research should focus on the
possible long-term effects of freshwater-rearing
regimes on smolt performance in the seawater phase.",

Our study used a typical tropical reservoir and fish as

metal bioaccumulation in fish. Specifically, Cr, Mn,
Fe, Ni, Cu, Zn, Cd, and Pb concentrations in water,
sediment, and fish, and {\delta} 13 C and {\delta} 15 N
in 13 fish species were detected in the Songtao
Reservoir of Hainan Province, southern China. Our
results indicated that Zn concentration in carnivorous
fish was higher than in omnivorous fish. Principal
components analysis visually differentiated pelagic,
benthopelagic, and demersal fish groups. Moreover, we
found that the fish feeding in the demersal habitat
showed higher heavy metal levels than those in the
pelagic habitat. Additionally, the heavy metal contents
in demersal fish were significantly positively
correlated with sediments, while no positive
correlation was observed in pelagic-feeding fish. The
{\delta} 15 N and the concentration of Ni, Zn in fish
had a significantly positive correlation, suggesting
the potential biomagnification. In contrast, Ni, Fe,
Cu, and Cd negatively correlated with fish body
weight/length, indicating the growth dilution effects.
Finally, the estimated daily intake (EDI) of the metals
was far below the provisional tolerable daily intake
(PTDI), and target hazard quotients (THQ) were
{$<$1}.0, indicating that the fish had no risk for
consumption risks. Overall, our finding partially
validated the hypothesis that the feeding habits and

The results showed that random forest (RF) demonstrated

Binary presence--absence maps showed the different

primarily found the freshwater species (P. sinensis and
H. bleekeri) present in the South Branch (west of
{122$^\circ $} E), whereas we found the marine species
(E. japonicus) anywhere except inside the South Branch
(west of {121.8$^\circ $} E). The area for P. sinensis
(1615.93 km 2) was relatively larger than that for H.

abstract = "Examining temporal changes in the growth and
generation time of fish species can be valuable for
understanding population responses to different
management measures and environmental conditions.
Atlantic herring (Clupea harengus -Linnaeus, 1758) is
an ecologically and commercially important pelagic
forage fish species that occupies the southern Gulf of
St. Lawrence. Here, we developed von Bertalanffy growth
curves and estimated yearly values of generation time
for NAFO Division 4TVn Atlantic herring for the years
from 1988 to 2021. The results indicate a temporal
reduction in the growth and generation time of both
spring and fall spawning herring. Over the time series,
the generation time of spring and fall spawners reduced
by approximately 1 and 2 years, respectively.
Furthermore, the average generation time of spring
spawners across the time series (6.23 years (95\% CI:
5.78--6.85 years)) was approximately 1 year lower than
that of fall spawners (7.52 years (6.82--8.34 years)).
Overall, the findings of this study can be used to
better inform stock assessments and rebuilding plans
for 4TVn spring and fall spawning Atlantic herring and
highlight the importance of examining temporal trends
in growth and generation time for more effective
management of fish stocks.",

0.83, and 0.91, respectively, in the Reynolds number
range of 1 $ \times $ 10 4 --1 $ \times $ 10 6. The
current-driven upstream mooring line was more dominant
than the wave-driven tension, and a simplified model of
the longline facility accurately predicted the mooring
line tension under the current conditions. The scope of
the mooring line (defined as the length of the mooring
line related to the water depth) played an important
role in eliminating an order of magnitude difference in
mooring tension under the wave conditions. The
amplitudes of the vertical movement of the longline
facility were smaller than the wave height when L / L m
was less than 1.5. Therefore, detailed information is
needed to better understand the hydrodynamic
characteristics and motion response of longline
aquaculture facilities for the safe operation of
longline structures in offshore environments, in order

of malformations in other fish species has been
associated with the content of long-chain PUFA
(LC-PUFA) in neutral lipids of the diet, the
relationship between body LC-PUFA and the rate of
malformations, together with a transcriptomic analysis
of genes related to the metabolism and transport of

been investigated in the present work. A total of 10

at about 22 {$^\circ $}C following the protocols of a
Chilean commercial hatchery during the spawning season.
There were three larval batches that were collected in
August (austral winter), three batches that were
obtained in October (spring), and finally four spawning
events that were obtained in December-January
(spring-summer). The rate and type of jaw
malformations, the profile of long-chain PUFA (LC-PUFA)
of total lipids during larval culture, and the
distribution of LC-PUFA were analyzed. Additionally, a
transcriptome analysis related to lipid metabolism in
40-day-old larvae was performed. As a result, a
decrease in the rate of malformations was recorded from
August to December. DHA showed a steep decrease between
days 1 and 10 of culture, probably due to the
consumption of yolk sac lipids, but a higher
proportional change was noted in larvae that hatched
during August. The DHA content in polar lipids (PL) and
neutral lipids (NL) of 40-day-old larvae increased from
August to December, so that the abundance of DHA was
higher in PL in larvae that hatched in December, but it
was higher in NL in those larvae that hatched in
October. In conclusion, the rate of jaw malformations
was associated with the rapid decline in DHA during
early larval life and the highest abundance of DHA in
neutral lipids at the end of the larval life.",

The gill arch was a curved cartilaginous structure,

by epidermal tissue rich with mucous cells. The primary
lamella had a central cartilaginous support and
efferent and afferent arterioles and was covered with
pavement cells (PVC), salt-secreting chloride cells,
and pale-staining mucous cells. These chloride cells
contained abundant mitochondria and tubulovesicular
system and are involved in ionic transport with a
potential role in detoxification. The surface of the
secondary lamellae (site of gaseous exchange) consisted
of overlapping or interdigitating PVC supported and
separated by pillar cells. Other cells were found
within the gill epithelium and interstitial connective
tissues, including lymphocytes, macrophages, monocytes,
telocytes, stem cells, astrocytes, and neuroepithelial

G{\"u}nther, 1872) is commonly caught as bycatch in the
Mexican Pacific, but changes in its reproductive
ecology as a consequence of fishery effects have never
been investigated. In this work, the reproductive
ecology of this species was determined in the Southern
Gulf of California (SGC). Total length (TL) ranged from
11.4 to 51.6 cm, and females were larger than males.
Size at maturity (TL 50) was estimated at 27.5 cm for
females and 25.3 cm for males. The seasonal variation
of mature individuals, the presence of pregnant
females, the mean oocyte size, the size of embryos and
the smallest free-living specimens along the year
suggest the existence of two reproductive periods
during the year in the SGC, and the size of birth was
estimated to be 11.2 to 15.6 cm TL. The average
fecundity was 2.14 embryos. Spatial variations detected
in size at maturity, fecundity, and reproductive cycle
along the Mexican Pacific coast suggest the presence of
separated populations. Some of these differences could
be related to differences in maximum size attained in
each region, though fishing pressure and environmental
factors could have an important role, too.",

suggesting that high levels of unrepaired DNA lesions
activated p53 to trigger apoptotic activity in mutant

2018 when they were transferred to 9 {$^\circ $}C
seawater with natural photoperiod for 2.5 years (final

belonging to 402 species of 82 families in China and
investigated the change of fish body shape in the
function of their ecology. Herbivorous fish tended to
be shorter and fatter than carnivorous fish, and
omnivorous fish fall somewhere in between. This
difference could be due to variations in feeding habits
and the availability of food sources. Additionally,
fish living in lentic waters tended to have a shorter
and fatter body shape compared to those living in lotic
waters. This could be attributed to differences in
swimming behavior in these environments. Furthermore,
our results showed that the b value decreased as
altitude increased, and fish tended to be thinner and
longer due to lower oxygen and temperature levels in
high-altitude waters. Overall, our study provides
valuable insights into the WLR of fish and the impact
of multiple factors on fish body shape.",

Steroid-related pathways were heavily affected during
stages II to III, while significantly altered

accomplish this, bulk stable carbon ({\delta} 13 C) and

years at the Ningaloo Reef aggregation site, Western

correlated. As turn-over times of the parasite and
whale shark differ (months vs. years, respectively),
the ability of copepods to predict {\delta} 15 N values
indicates that the trophic positions of whale sharks
remain consistent across these timeframes.
Contrastingly, {\delta} 13 C in the parasite and host
were weakly correlated, likely reflecting differences
in the physiology and lifecycle of the copepod parasite
compared to the host. Our results suggest {\delta} 15 N

catch-per-unit-effort (CPUE) decreased significantly
from 2011 to 2022. The generalized linear model (GLM)
indicated that daily changes in Japanese glass eel
collection were significantly affected by tidal range,
water temperature, and lunar distance. The catch peak
appeared when the tidal range rose to 1.7 m, and the
water temperature dropped below 8 {$^\circ $}C on the
full moon days. Overall CPUE analysis showed no
significant periodic and inter-annual variability in
the period 2011--2022, with the ARIMA model suggesting
that the CPUE is expected to remain stable but low in
the coming years (2023--2026), although recruitment
ultimately depends on the overall spawning stock.",

The potential for sex reversal to impact reproductive

eight microsatellite markers, we found moderate genetic

we found that all populations are at mutation drift
equilibrium, while the Nm between any two populations
is greater than 1. We hypothesized the existence of
island model gene flow patterns among E. sinensis.
Interestingly, genetic differentiation among E.
sinensis populations was low, except that between
Liaohe and Anqing or Shanghai populations.
Additionally, geometric morphological analysis could
distinguish E. sinensis from different basins, with an

significant increase in the number of Mesanophrys sp.

the eyestalks, gills, heart, nerves, muscles and
hepatopancreas) at 3 h post-infection. The numbers of
Mesanophrys sp. in the gill, eyestalk and nerve tissues
were relatively higher than in the other tissues. The
gill tissue showed the highest numbers from 6 to 48 h.
Histopathological observation found a severe collapse

representative tissues (gill, muscle and

after a recent description recorded from the Balearic
Islands and from the slope of the Gulf of Vera on the
Iberian Peninsula coast. The record from the Emile
Baudot seamount on the Balearic Islands represents the
deepest positive benthic gobiiform species record in
general. The presence of the membrane connection
between the pelvic fins in Gymnesigobius medits,
presumed on the damaged fin in the original
description, was confirmed. The recently described
Gobius xoriguer is the first record from the Pitiusas
and Columbretes islands and from the Iberian Peninsula
coast. It appears to be widely distributed in the
circalittoral bottoms, preferentially in red algae
beds. Morphological identification of both species was
confirmed using molecular analyses based on the
sequencing of the mitochondrial cytochrome c oxidase
subunit I (DNA barcode) gene. The deepest records of
gobiiform fishes in oceans and seas are reviewed. The
European seas, a well-studied area with eight gobiid
species recorded deeper than 200 m, show high bathyal
gobiid species richness compared to other areas. The
real worldwide diversity of bathyal gobies, although
only a fraction of the shallow water species richness
of this taxon, is probably much larger than presently
known.",

crude protein content was the highest in seabream fed
the TRO and INS diets. Crude fat was the highest value

observed in seabream-fed IBE and INS diets. Except for
EAA methionine (Met), there were no static differences
in retention efficiency. The diet with the highest
hydrolysis rate was IBE. Diet differences were
significant but had the typical healthy liver

become crucial in controlling sea lice levels in

is a need for early sex identification. The genomic
region containing the anti-M{\"u}llerian hormone (amh)
gene was suggested as the candidate master
sex-determining gene in lumpfish. However, the genome
of lumpfish contains three copies of amh with ambiguous
sex specificity, designated amh1, amh2, and amh3. The
study aims to analyse the male-specific region between
these amh paralogues for its application as a sex

male-specific amh markers in lumpfish and estimate the
length of the male-specific region in the lumpfish
genome. Our results indicate that a specific genomic
region of approximately 27 kilobases (kb), encompassing
amh1 and amh2 genes, exhibits male specificity, whereas
amh3 is present in both sexes. The developed PCR-based
genetic sex identification assays targeting amh1 and
amh2 exhibited over 97\% concordance with phenotypic
records. Further experiments in other members of the
Cyclopteridae: Aptocyclus ventricosus, Eumicrotremus

The ATP content, K-value, pH, total microbial count,

showed that the average WT was considerably decreased
in the shaded pond with no significant difference in
the DO concentrations. Red blood cells, hemoglobin, and
lymphocyte counts were significantly lower in fish
raised in shaded ponds, although mean corpuscular
volume and neutrophil counts were significantly higher.
Likewise, Chole, TP, and Alb values were significantly
affected by the interaction of cycle and shading setup.
Cortisol, Glb, K +, Cl {$-$}, Mg 2+, and TCa values
showed significant differences and were only affected
by the cycle. Similarly, AST and ALT values showed
significant differences and were affected by both cycle
and shading setup. Water quality parameters (WT and
DO), hematological blood indices, and serum biochemical
variables were correlated positively with each other.
In brief, prior data imply that net shading can reduce

indicating high local uniqueness and relative isolation
among river basins. Some alleles are regional markers
since they are rare or absent from contemporary

size suggested good conservation status, with higher
values than those estimated for contemporary
populations. Strong population structure and genetic
differentiation between rivers were found, with limited

Yet, the ocean has experienced a loss of approximately
2\% of its oxygen inventory since the last century,
resulting in adverse impacts on marine life and
ecosystems. In particular, changes in the gap between
the supply and demand for dissolved oxygen lead to
physiological and ecological variations, which cause
alterations in habitats and food webs for fish and
ecosystem services. These changes vary over time and by
region, and the heterogeneous characteristics of marine
species bring about non-linear consequences to human
society. Despite this, identifying the potential ripple
effects of deoxygenation on human society is
challenging due to the integrated impacts of other
stressors, such as global warming and ocean
acidification, and their varying changes depending on
environmental conditions and regions, such as upwelling
and eutrophication. Therefore, we conducted a
literature review on ocean deoxygenation and its
effects on fish dynamics and the ecosystem, with a
focus on the environmental and societal impact, to
present crucial considerations and pathways for future
research on ocean deoxygenation. We found that
quantitative approaches are necessary to assess the
dynamic changes under deoxygenation, and the consequent
effects on marine ecosystems should be verified to
exploit the natural resources from the ocean. One of
the most reliable approaches to quantifying the ripple
impacts of deoxygenation is to model spatial and

gaining insight into the underlying mechanisms

can aid in the improvement of grouper growth rates.
However, the mechanism behind growth differences in

transcriptome profiles of muscle tissues between fast-
and slow-growing brown-marbled grouper using RNA-seq
and identified 77 significantly up-regulated genes and
92 significantly down-regulated genes in the extreme

genes such as stc2 and pdp1, are associated with growth
advantages in brown-marbled grouper. We used
differentially expressed genes (DEGs) for GO and KEGG
enrichment analyses. The results of the GO enrichments
showed that the significantly up-regulated genes in the
fast-growing group were involved in protein folding,
the actin cytoskeleton, the myosin complex, and other
processes. The results of the KEGG enrichments showed
that the significantly up-regulated genes in the
fast-growing group were involved in various pathways
such as glycolysis/gluconeogenesis, adipocytokine
signaling, MAPK signaling, carbon metabolism, and
PI3K-Akt signaling. Additionally, gene set enrichment
analysis (GSEA) showed that the PI3K/AKT/mTOR pathway
was up-regulated in the fast-growing group, which may
be responsible for the higher nutrient absorption
efficiency and muscle growth in these fish. Our results
contribute to a better understanding of the molecular
mechanisms and regulatory pathways underlying fast

were found in the treatment of 1000 {\SGMLmicro}atm pCO
2. The lowest pCO 2 concentration was found to be
within the optimum healthy blood parameter range. The
fish exposed to acidic conditions (700 and 1000
{\SGMLmicro}atm) exhibited considerably higher levels
of haemoglobin and haematocrit compared to the control
fish. Glucose levels were significantly lower in the
acidic conditions, while total cholesterol levels in
mahseer fish exposed to acidic conditions were higher.
The fish displayed skeleton malformations as the

the juvenile rearing of mahseer fish under acidified

abstract = "Species of the genus Pseudoplatystoma, the
long-whiskered catfishes, are important in commercial
and recreational fisheries in South America, and some
species have become key to regional aquaculture. Some
species of the genus are under pressure due to
overfishing and the negative impacts of dams. Six
questions are asked in this review: (i) What species
are in the genus, and where are they distributed? (ii)
What are the life histories and ecologies of
Pseudoplatystoma species? (iii) What are the patterns
of somatic growth for these species? (iv) What is known
about the biomass, production, and population dynamics
of Pseudoplatystoma? (v) What is the geographic
distribution of genetic variation within
Pseudoplatystoma species? (vi) What are the threats to
the conservation of these species? The taxonomy of the
genus currently includes eight species, respectively,
distributed over the Orinoco, Amazon, Paran{\'a}, and
S{\~a}o Francisco basins. Pseudoplatystoma catfishes
typically exhibit longitudinal migrations for
reproduction and lateral migration for feeding, but
these patterns may vary among populations. The size of
the first maturation of these catfishes varies between
57 cm to 82 cm in total length. Five of the eight
species spawn during the rising water season.
Pseudoplatystoma species can grow to about 130 cm in
total length and 100 Kg in weight and live until 30
years of age, depending upon the species. Biomass
production and population dynamics of these catfishes
have not yet been fully described. Their life-history
characteristics indicate that they are periodic
strategists with associated population recruitment
dynamics. Population genetic patterning varies among
Pseudoplatystoma species, with some degree of homing
behavior and genetic differentiation among populations,
indicating the need for management by applying the
Management Unit and perhaps Evolutionary Significant
Unit concepts. The main threats to the persistence of
these catfishes are overfishing and alterations in and
obstruction of river flow due to the construction of
hydropower dams. After synthesizing existing
information on species of the genus Pseudoplatystoma,
we offer suggestions for future research to fill
critical gaps in the knowledge of this group.",

that intensive commercial fishing had a considerable

the decline was potentially amplified through a wider

requires successful migration between nursery, feeding,
and spawning habitats. Smolting is the major
transformation anadromous salmonids undergo before
migration to feeding areas. It prepares juvenile fish
for downstream migration and their entry to seawater.
We reviewed the effects of climate change on smolt
ecology from the growth of juveniles in fresh water to
early post-smolts in the sea to identify the potential
effects of climate change on migratory salmonid
populations during this period in their life history.
The focus was especially on Atlantic salmon. The shift
in suitable thermal conditions caused by climate change
results in Atlantic salmon expanding their range
northward, while at the southern edge of their
distribution, populations struggle with high
temperatures and occasional droughts. Climatic
conditions, particularly warmer temperatures, affect
growth during the freshwater river phase. Better growth
in northern latitudes leads to earlier smolting.
Thermal refuges, the areas of cooler water in the
river, are important for salmonids impacted by climate
change. Restoring and maintaining connectivity and a
suitably diverse mosaic habitat in rivers are important
for survival and growth throughout the range. The start
of the smolt migration has shifted earlier as a
response to rising water temperatures, which has led to
concerns about a mismatch with optimal conditions for
post-smolts in the sea, decreasing their survival. A
wide smolt window allowing all migrating phenotypes
from early to late migrants' safe access to the sea is
important in changing environmental conditions. This is
also true for regulated rivers, where flow regulation
practices cause selection pressures on migrating
salmonid phenotypes. The freshwater life history also
affects marine survival, and better collaboration
across life stages and habitats is necessary among
researchers and managers to boost smolt production in
rivers. Proactive measures are recommended against
population declines, including sustainable land use in
the catchment, maintaining a diverse mosaic of habitats
for salmonids, restoring flow and connectivity, and
conserving key habitats.",

(ANT-A), we hypothesized that variations in amino acids
at the ANT-A binding site may reflect toxicity
differences. Protein sequences for six motifs
comprising the ANT-A binding site were obtained and
compared for invasive carp species (N = 515) and seven
non-target species (N = 277); a consensus was
delineated from each species. The carp species, Common
Carp (Cyprinus carpio), Silver Carp (Hypophthalmichthys
molitrix), Bighead Carp (Hypophthalmichthys nobilis),
Grass Carp (Ctenopharyngodon idella), and Black Carp
(Mylopharyngodon piceus), showed the same amino acids
at the site; thus, it was termed the carp consensus
motif sequence (CCM). Channel Catfish (Ictalurus
punctatus) showed the most amino acid polymorphisms,
with three motifs 96--100\% different from CCM. Within
a species, Bluegill (Lepomis macrochirus) and Fathead
Minnow (Pimephales promelas) variation per motif was
most dissimilar (46.7\% and 21.6\%, respectively).
Organismal mortality data from the literature indicated
Yellow Perch (Perca flavescens), Walleye (Sander

cepedianum) to be most sensitive to the piscicide,
Catfish least sensitive, and all others intermediate.
The protein sequence variations of the binding site
appeared to be in accord with organismal sensitivity
categories when they differed from the CCM; the motifs
in Gizzard Shad and Walleye were the same as in CCM.
The physical/chemical nature of ANT-A is important to
consider in organismal response comparisons. This
cellular approach of studying ANT-A binding at its
target enzyme is a non-destructive way to predict
piscicidal efficacy of ANT-A against fishes of

immunological, anti-oxidation, and digestive enzymes.
Furthermore, the external noise also influenced the
locomotive patterns of the fish aggregations. Fish
polarity and cohesion were significantly more discrete
(p {$<$} 0.05) in both the RAS (47.79 {\pm}
{2.34$^\circ $} and 98.52 {\pm} 3.22 mm) and IPRS
groups (48.04 {\pm} {0.70$^\circ $} and 87.70 {\pm}
7.31 mm) compared to the Ambient group (42.76 {\pm}
{1.42$^\circ $} and 85.73 {\pm} 1.57 mm). These results
highlight the significant impacts of the aquaculture
soundscape on the development, physiological
activities, and behavioral traits of largemouth bass.
Future research should focus on determining and
optimizing the impact of different equipment noise to
ensure optimal welfare and production performance in
aquaculture systems.",

operational status of fishing vessels can be identified
by using onboard cameras to detect the deck crew and

significant memory consumption of detection models,
general target detection models are unable to perform

lightweight real-time deck crew and the use of a
fishing net detection method, YOLOv5s-SGC. It is based
on the YOLOv5s model, which uses surveillance cameras
to obtain video of fishing vessels operating at sea and
enhances the dataset. YOLOv5s-SGC replaces the backbone
of YOLOv5s with ShuffleNetV2, replaces the feature

experiment, the ND and CCD groups were named PI\_ND and
PI\_CCD, respectively. CCD increased superoxide

of liver tissue identified 62 differentially expressed
proteins (DEPs) in CCD vs. ND, and 36 DEPs in the
PI_CCD vs. the PI_ND groups. Furthermore, 80 specific
upregulated proteins and 49 specific downregulated
proteins were screened in the CCD group. The specific
upregulated proteins included important antimicrobial
enzymes such as lysozymes and cathepsin D, and
antimicrobial peptides such as septins, granulin, and
grancalcin, involving multiple KEGG brite categories
such as enzymes, exosomes, membrane transport, and
proteolipid proteins. Furthermore, specific
downregulated proteins were enriched in
glycolysis/gluconeogenesis and TCA cycle pathways. In
conclusion, CC supplementation effectively enhances the
ability of tilapia to resist SA infection by modulating
various antioxidant enzymes, immune factors,
antimicrobial enzymes, and antimicrobial peptides, and
by moderately inhibiting central carbon metabolism.

maturational competence (OMC), which is the ability of
the oocyte to respond to the MIS. Nevertheless, the
addition of rhIGF1 with the MIS increased the
proportion of oocytes completing GVBD compared with MIS
alone, although this potentiation was small and varied
greatly among clutches of follicles from fish with
oocytes at different stages of germinal vesicle

IGFs may have synergistic actions with the MIS but
cannot induce resumption of meiosis directly at the

cluster analysis showed that three of the seven
surveyed populations were genetically distinct, while
the other four populations showed signs of recent
admixture. Estimated effective population sizes and m
-ratios were low within most populations, suggesting
loss of alleles due to recent genetic drift. Positive F
IS values, high average individual inbreeding
coefficients, and high degrees of inferred relatedness
among individuals suggested that inbreeding is taking
place in some populations. F ST values were high, and
analysis of molecular variance indicated genetic
divergence among populations. These indicators suggest
that Clinch Dace populations are subject to the genetic
processes that are characteristic of small and isolated
populations.",

A. phalaena were investigated for the first time.
Spawning occurred between 11:00 and 13:00, with the
breeding pairs naturally spawning 24 times from 1 June
2021 to 30 June 2022. The fecundity ranged from 11,022

approximately 81 h and 26 min after fertilization at a
temperature of 27.0 {\pm} 0.9 {$^\circ $}C. Newly
hatched larvae had a total length (TL) of 1.91--2.03 mm
with 24--26 somites. The larvae transformed into
juveniles at 30 days post-hatch. Experiments were
conducted at different temperatures (21, 24, 27, 30,

continuing to adopt new management frameworks. This is
due to a limited coherence on long-term policy making

between the two, and a paradoxical vision that promotes
DWF without the means to monitor fishing activities and
their impacts. The existing institutional settings and
governance frameworks make change possible in
Madagascar's approach to DWF. To improve the management
of DWF, this paper outlines four pathways. These
include (i) a greater attention on the implementation,
harmonisation and evaluation of existing policies and
projects; (ii) continuing efforts on transparency for
DWF operations and contract negotiations; (iii)
realigning aspirations and policies with local needs;
and (iv) taking better advantage of measures adopted at
the regional Indian Ocean level to improve national
management of DWF. An efficient implementation of an

strengthening the governance of DWF activities toward

qRT-PCR was performed to determine the mRNA expression

hemoglobin (Hb), and myoglobin (Mb) in response to

assess the transcriptional activity of HIF-1{\alpha} on

that the expression levels of HIF-1{\alpha} and PHD
mRNAs were highest in the gill and lowest in the
adductor muscle. Under hypoxic conditions,
HIF-1{\alpha} and PHD mRNAs were both induced, and
their expression levels increased significantly,
peaking at 8 h and gradually decreasing thereafter. The
transcription of Tg-PHD was induced by hypoxia and was
Tg-HIF-1{\alpha} dependent. Notably, the expression of
Hb decreased in hemocytes (p {$<$} 0.01) after 8 h at

post-mortem. Then, the bacterial isolates were
subjected to bacteriological phenotypic examination,
16S rRNA gene sequencing, and antibiotic sensitivity
testing. Histopathological screening and the immunity

norfloxacin, while they were resistant to erythromycin

melanomacrophage activation in most affected tissues of
infected M. cephalus were detected by light microscopy.
Nevertheless, higher levels of AST and ALT, as well as
serum inflammatory markers, CRP, and lysozyme activity,

levels, along with a reduction of GSH, SOD, and

low (L: 2.95 kg/m 3) --- and conducting transcriptome
sequencing before collecting liver samples at two time
points: 6 h (AL and AH) and 60 d (CL and CH) into the

expressed genes (DEGs) in the AL-vs-AH and CL-vs-CH
groups, respectively. The DEGs in the AL-vs-AH group
were significantly enriched in steroid biosynthesis,
terpenoid backbone biosynthesis, the PPAR signaling
pathway, proteasome, aminoacyl-tRNA biosynthesis, and
ribosome biogenesis in eukaryotes. The DEGs in the
CL-vs-CH group were more significantly enriched in
lipid metabolism-related pathways, such as the PPAR
signaling pathway, fatty acid metabolism, and
cholesterol metabolism. In addition, immune-related
pathways such as the phagosome and complement and
coagulation cascades were also enriched in the CL-vs-CH
group. The expression changes concerning the DEGs in
each group were further analyzed. The DEGs related to
steroid synthesis, protein synthesis, and the
degradation pathways were down-regulated, but
immune-related genes were generally up-regulated in the
AH group. The DEGs related to lipid synthesis were
significantly up-regulated in the CH group, but the
DEGs related to lipid consumption and utilization were
down-regulated. The expression of immune-related DEGs
was also negatively affected in the CH group. These
results suggest that acute and chronic crowding stress
affects lipid metabolism and immune regulation in the
liver of black porgy. Acute stress particularly
affected hepatic protein metabolism, while chronic
stress showed more effects on hepatic lipid metabolism.
The results of this study provide a theoretical basis
for understanding the effects of high stocking

abstract = "The Bagridae fish family holds significant economic
value and enjoys a high demand in the commercial market
due to its desirable characteristics, such as delicious
meat, fewer muscle spines, and a pleasing flavor. In
recent years, the Bagridae has experienced rapid
development in the seed industry in response to
industry demands. Researchers have conducted extensive
studies on genetic breeding in the Bagridae, employing
a comprehensive breeding approach that combines
conventional breeding techniques with innovative new
technologies and cooperative efforts. In this review,
we present an overview of the market situation and
discuss various breeding processes applied to the
Bagridae, including selective breeding, genetic
engineering breeding, cell engineering breeding,
molecular marker-assisted breeding, and hybrid
breeding. Additionally, we focus on introducing the
cultivation methods for two new Bagridae varieties.
Furthermore, we explore and summarize the breeding
conditions, genetic background, heterosis,
comprehensive breeding technology, stress resistance,
and metabolic nutrition of hybrid Bagridae catfishes.
Overall, noticeable heterosis has been observed in the
breeding of the hybrid yellow catfish ``Huangyou-1'',
which exhibits promising market prospects and economic
benefits for aquaculture. Our study aims to underscore
the importance of harnessing the heterosis of catfish,
particularly the Pelteobagrus and Bagridae species.
Consequently, this review provides an update on the
current available information regarding the seed
industry of the Bagridae fish family.",

important species found in the East Sea; along the
southern coast of Korea; south of Hokkaido, Japan;
around Taiwan; and in the East China sea. In Korea,
these two species hold high value, particularly on Jeju
Island. These species have similar appearances, and it
is challenging to distinguish them, particularly during
the seed period. We detected genetic differences in the
mtDNA (COI gene) of G. punctata and G. leonina, which
are morphologically indistinguishable, and developed
species-specific genetic markers for their
identification. In total, 16 and 4 haplotypes of the
COI genes were obtained from G. punctata (n = 164) and
G. leonina (n = 36), respectively. The haplotype
diversity (Hd) and nucleotide diversity (Pi, \%) of the
COI were 0.359 and 0.054 for G. punctata and 0.560 and
0.078 for G. leonina, respectively. We designed a
Girella species common primer (control) and
species-specific primer sets (experimental) for the two
species. Amplicon sizes of 991, 579, and 391 bp were
obtained for common primers of the two Girella species
G. punctata and G. leonina. To confirm multiple targets
in a single reaction, multiplex PCR conditions were
optimized to adjust its resolution and accuracy. The
detection levels of the multiplex PCR were confirmed to
be 0.01 ng/{\SGMLmicro}L for the two Girella species.
The multiplex PCR was not associated with
cross-reactivity between G. punctata and G. leonina.
This multiplex species-specific PCR method provides a
simple and rapid technique for the identification of
two Girella species, thus increasing the efficiency and
quality of Girella species stock management and
forensic identification to prevent species
misidentification.",

reverse the decreased activities of lipase, protease,

pathogenic bacteria of juvenile American eels exposed

increasing the activity of digestive enzymes, improving

Of 653 unique fish captured (not including 118

Furthermore, 117 bacterial strains were isolated in
different culture media from the gastrointestinal tract
of S. aurata fed the microalgae blend and further
characterized for their potential use as probiotics in
aquaculture. S. aurata fed the microalgae-supplemented
diet (25\% dietary inclusion) showed a significant
increase in weight gain, specific growth rate, feed
efficiency, hepatosomatic, and intestine length
indices. However, growth performance and somatic
indices in M. cephalus were not affected by the

more evident. Reactive oxygen species (ROS) production,

temperature increases; Methods: To enlighten the

viviparous teleosts called Xiphophorus, are unique
models for studies of evolution of sex chromosomes.
Monofactorial sex-determining systems, with either the
male or the female being the heterogametic sex, as well
as sex determination involving more than two sex
chromosomes, are found in swordtails and related
species. Some swordtail species seem to have originated
by crossing between two closely related species.
Although the sword has disappeared in many Xiphophorus
species during evolution, females of non-sworded
species still prefer sworded males, demonstrating a
discrepancy between natural and sexual selection.
Natural sex change has not been documented sufficiently
convincingly in swordtails, but, at least in some
subspecies, two or more male phenotypes exist. In a
laboratory experiment performed for over 30 years, it
has been observed that sex-determining genes may be
translocated from one chromosome to another in hybrids
of these evolutionary young species. While the factors
suggested to play central roles in sex determination
and differentiation, e.g., Dmrt1 and AMH, are highly
conserved during evolution, several master determining
factors have been detected in teleosts.
Endocrine-induced sex reversal has been demonstrated in
the guppy Poecilia reticulata, another viviparous fish.
In swordtails (X. helleri), endocrine disruptors such
as nonylphenol and bisphenol A may cause testis cell
degeneration and the inhibition of spermatogenesis.
Furthermore, swordtails are very easy to breed in
freshwater aquaria and, therefore, may be good models
for studying the factors influencing sex determination
and male differentiation.",

weight gain and feed efficiency occurred with 42.2 and
49.8 g kg {$-$1} of SL inclusion, respectively,
estimated through quadratic regression after 90 days of
feeding. The body composition of the fish was also
affected by feeding with SL, with a decrease in total
body lipids and viscerosomatic and hepatosomatic
indices but an increase in polyunsaturated fatty acids.
A digestibility trial using only two diets (0SLD and
43SLD) revealed increased lipid and fatty acids
digestibility in fish fed with 43SLD. In addition, the
consumption of digestible nutrients was the highest in
fish fed the diet 43SL. Therefore, SL supplementation
is beneficial in fall/spring diets for Nile tilapia
juveniles as it can improve growth, lipid
digestibility, and body composition when supplemented
within the range of 42 to 50 g kg {$-$1} diet.",

occurring at night. We estimated a 3\% probability of a
released fish entering the structure, then 89\% and
99\% passage to the midpoint and exit of the 123 m

due to low recapture probability of small-bodied study
organisms in a relatively large system, and the low
percentage of space of the entryway on this barrier
({$<$3}\% of the length of the barrier). Fish that
entered the structure ascended quickly, with median
time for successful ascent of 19 min, and minimum time

abstract = "The eastern Mediterranean Sea is one of the most
invaded marine ecosystems due to the introduction of
Lessepsian species, which migrated from the Red Sea to
the Mediterranean Sea following the construction of the
Suez Canal. Some of these species may initially appear
to be beneficial for fisheries by providing additional
income sources for fishers; however, this usually
occurs at the expense of negatively impacted native
species and, thus, the ecosystem, which leads to
greater economic losses for the fisheries in the long
term. Therefore, this study aims to quantify the impact
of N. randalli, which is one of the Lessepsian species
with increasing commercial importance for the
fisheries, on the food web dynamics in a coastal
ecosystem in the northeastern Mediterranean Sea using a
mass-balance food web modelling approach by
capitalising on field data obtained from trawl
samplings conducted within the scope of the study.
Results showed that the ecosystem was in a
developmental stage and experienced an autotrophic
succession. The keystone fish group with a structuring
role in the food web was sea breams and porgies.
Although N. randalli had positive impacts on certain
commercially exploited indigenous demersal fish species
by mitigating the negative impact of another Lessepsian
species, i.e., Saurida undosquamis (Richardson, 1848),
in the food web, it had a negative impact on the
keystone group of the food web, i.e., sea breams and
porgies. Therefore, N. randalli poses a potential
threat to the ecosystem's structure, and the
interactions of N. randalli with other species in the
food web may instigate an ecosystem reorganisation in
the future. We suggest targeted fisheries exploitation
and incentives for the fishery of N. randalli as
management strategies to mitigate its negative impacts.
However, the mitigating role of N. randalli in
regulating the negative impacts of S. undosquamis could
be adversely affected by its increasing exploitation;
therefore, future modelling studies should consider
scenario simulations to test such effects.",

Tailoring an adequate legislative framework with clear

framework and current institutional tools for the
conservation of marine endangered and threatened
species in the Russian Federation. In this regard,
important legislative tools include federal laws, as
well as internationally binding signed agreements,
among others, such as the Convention on International
Trade in Endangered Species of Wild Fauna and Flora
(CITES) and the Convention on Wetlands of International
Importance Especially as Waterfowl Habitat (Ramsar). A
strategy and an action plan for the conservation of
biological diversity were also developed. Besides, the
most important tool for the conservation and protection
of marine endangered and threatened species is the Red
Book of the Russian Federation (RBRF) and other
regional Red Books. Responsibility for causing harm to
the species listed in the RBRF and their habitat is
specified in the code of administrative offenses and
the criminal code of the Russian Federation. Finally,
conclusions and identified gaps were highlighted in the
last section, including, among other things, that
legislation is still limited in how it takes the
impacts of climate change into account. Such type of
study is highly recommended, considering the relatively
few number of papers dedicated to the study of the

for dictating the population status and spatial
distribution of cold-water stenotherm salmonids in the
mid- to southern extent of their range. The global
climate is predicted to continue to warm, and
therefore, the overall thermal suitability of
freshwater habitats for stream salmonids is predicted
to decline in concert. However, stream and river
thermal heterogeneity will offer considerable
resiliency for these populations. Thermal refuges are
formed by many physical processes; common natural
refuges include cold tributary plumes, groundwater
springs, alcoves, and hyporheic upwellings. However,
many anthropogenically formed refuges (such as
stratified reservoirs or cold-water tailrace outflows)
also exist in hydropower-regulated rivers. The
significance of these refuges to stream salmonids
depends on their size and temperature differential, but
also other habitat characteristics such as their depth,
flow velocity, Froude number, and many biotic factors
within the refuges. Modern technologies such as
drone-mounted thermal infrared cameras and other remote
sensing techniques allow for the efficient
identification of such refuges, and inexpensive options
include the identification of refuges during ice cover
using orthophotographs. Behavioural thermoregulation,
i.e., salmonids aggregating in cold-water refuges, can
be either facultative or obligate and the timing of
these events is governed by life stage, species, and
population-specific physiologically regulated
cumulative thresholds that are inherently related to
the recent thermal history, or hysteresis, of each
individual. Salmonids appear to have an excellent
spatial cognition for locating and relocating
cold-water refuges, and their spatial distribution is
largely affected by the availability of the cold-water
refuges during the warm-water period in many thermally
stressed rivers. Gregarious behaviour is the norm for
salmonid fishes within the thermal refuges; however,
the size/microhabitat hierarchy appears to dictate the
within-refuge distribution at the micro-scale. There
continues to be a great impetus for protecting---and in
carefully determined cases creating---cold-water
refuges in the future. A thorough understanding of what
a ``goldilocks'' refuge is for various salmonids and
their different life stages will be imperative as
cold-water restoration is gaining popularity. Finally,
disentangling the roles of the climate-induced and
landscape activity-induced warming potential of fluvial
freshwater will be important to ensure continued
environmentally responsible landscape activities in
future waterscapes.",

environment and the tuna-freezing process. Lower
temperatures and higher air increased the velocity at
which the tuna moved through the maximum ice crystal
formation zone, maintaining a better aquatic product
quality. In some cases, however, the smaller tuna
models achieved a longer freezing time. Due to the
difficulty of obtaining the whole tuna sample, the
temperature curve and freezing rate over time obtained
during the freezing process were tested using a tuna
block of a specific size. The maximum error did not
exceed 6.67\%, verifying the authenticity and

carbon ({\delta} 13 C) are ubiquitous ecological
tracers used to elucidate an organism's diet and
habitat. However, the application of stable isotope
ratios to reconstruct a consumer's ecology relies upon
accurate rates for isotopic turnover at both a tissue
and species-specific level. This study estimated
isotope turnover rates and trophic discrimination
factors in four different tissues (liver, digestive
tissue, muscle, and skin) with variable metabolic
activity in winter flounder Pseudopleuronectes
americanus using a controlled diet-switch experiment.
Differences in half-lives were noted among the tissues
and between the experimental diets for both {\delta} 15
N and {\delta} 13 C. The experimental diets of krill
and mysis had variability in nutritional composition,
resulting in similar turnovers in {\delta} 15 N but
slower turnovers in {\delta} 13 C for fish fed krill.
Turnovers in both {\delta} 15 N and {\delta} 13 C were
strongly influenced by metabolism, with the
contribution reaching up to 98\%, as fish exhibited
minimal overall growth. The results of this study
demonstrate the importance of considering differences
in the catabolic activity of tissue maintenance for
fish exhibiting minimal growth, as well as differences
in metabolic assimilation of dietary sources that vary

alternative is attracting attention for boosting

searched included `BFT', `carbon use efficiency',
`carbon conversion', `carbon retention', `carbon
emission', `carbon loss', and `carbon release'. The
current review discusses the possible effects of
various C/N ratios, carbon types, addition strategies,
and technology integration with respect to the
optimized carbon utilization in BFT. Given the extreme
lack of accessible research, it was concluded that the
carbon utilization in BFT is still in its initial

plausible approaches for boosted carbon utilization by
adopting slow-release carbon, reducing carbon input,

In this study, we aimed to assess the effects of an
acute 2 h sub-lethal exposure to different levels of
the pyrethroid esfenvalerate on the swimming behaviour
of two Cypriniformes species: the native Iberian barbel
(Luciobarbus bocagei) and the non-native invasive bleak
(Alburnus alburnus). The experimental set-up consisted
of previous exposure to three esfenvalerate
concentrations (control, 1.2 (low), and 2.0 (high)
{\mu}g/L) before being stocked in a
three-artificial-flume-channel mesocosm for behavioural
trials through direct observation. Monitored behaviours
included (i) routine activity, (ii) shoal cohesion, and
(iii) boldness. Significant differences in fish
behaviour were detected for the native species
(barbel), as individuals spent significantly more time
holding position (i.e., resting) in the control
(44.9\%) than in the high esfenvalerate concentration
(25.2\%). Concordantly, control barbels were also found
to perform more directional changes than the ones
exposed to high esfenvalerate concentrations.
Behavioural changes were also found for boldness,
measured by the proportion of fish attempts to
negotiate the upstream ramp, which were significantly
higher in the control (37.4\%) and in the high
concentration (41.5\%) compared to the low one
(21.1\%). Finally, regarding shoal cohesion of the
barbel, it was tighter in the control (81.3\%) than in
the low- (70.5\%) and high- (71.1\%) esfenvalerate
treatments. For the invasive bleak, there were no
significant differences in any of the behavioural
traits upon previous exposure to an increasing
esfenvalerate concentration. This experimental study
demonstrated that even short-term exposure to the
pyrethroid esfenvalerate was sufficient to alter the
behaviour of a native Cypriniformes fish species while
not affecting the non-native species. This may confer
greater competitive advantages to non-native fish
species in the context of global changes.",

waters of the Amur River in China, this study
investigated the status of juvenile chum salmon
resources and their basic biological characteristics in
the Amur River and the Ussuri River in China. The
results showed that the average catch per unit effort
(CPUE) of chum salmon in river margins was 0.140
ind{\cdot}10 {$-$3} m 3 for the Amur River and 0.255
ind{\cdot}10 {$-$3} m 3 for the Ussuri River. Chum
salmon migrate downstream, mainly in mid-May in the
Amur River and in early May in the Ussuri River, and no
fish was caught in the rivers after June. Most chum
salmon migrated when the water was between 10 and 14
{$^\circ $}C. The average FL (fork length) and BW (body
weight) of the Amur River samples were 37.1 {\pm} 2.9
mm and 0.42 {\pm} 0.09 g, respectively, while the
Ussuri River samples' FL and BW were 34.9 {\pm} 3.7 mm
and 0.36 {\pm} 0.08 g, respectively. The empty stomach
rate of the samples was zero, and the prey category of
the samples was composed of fish, aquatic insects,
copepods, and cladocerans, of which Ephemeroptera had
the largest percentage index of relative importance
(IRI \%), with a value of 58.45\%. The size of the
downstream-migrating juvenile chum salmon in this study
is similar to the size of those in some other rivers,
and the CPUE varies depending on the river
conditions.",

sustainable salmonid aquaculture. The species display
high evolutionary potential, which is evident by its
development of resistance to numerous chemical
compounds used for delousing. In response to this,
salmon farms now use non-chemical delousing methods to
minimize the damage done by salmon lice, including
heavy reliance on cleaner fish. Anecdotal reports from
farmers and fish health personnel in areas where
cleaner fish are used have suggested that salmon lice
are becoming less pigmented, potentially making them
harder for cleaner fish to visually detect. This
experiment investigated changes in the pigmentation of
salmon lice in relation to the use of cleaner fish,
louse stage and sex, temperature, preferred salmon
swimming depth, daylength, and salinity. Salmon lice
were sampled from snorkel cages on a commercial salmon
farm where three cages were stocked with farmed
lumpfish and ballan wrasse, and three cages were
without cleaner fish. Water temperature, salinity, and
depth were recorded using a conductivity, temperature,
and depth recorder. Pigmentation was measured via
photographic analysis of individual lice. Although
louse pigmentation varied considerably throughout the
experiment, using cleaner fish throughout a single
production cycle did not reduce average louse
pigmentation compared to control cages. On average,
male lice were significantly darker pigmented than
females, but otherwise there were no patterns in louse
pigmentation in relation to life stage, salinity,
temperature, or daylength. Salmon lice exhibit a high
degree of evolvability and have become resistant to
every chemical removal treatment developed thus far.
The present data suggest that, with the densities and
species of cleaner fish commonly used in commercial
salmon production, there is not strong directional
selection on louse pigmentation. Lice, at least with
regard to visual appearance, are not likely to adapt in
a way which reduces cleaner fish efficacy anytime
soon.",

assessment employed a multivariable model that
considered the sensitivity of marine and coastal
ecosystems that support fishing resources alongside
fishermen's adaptability to changes in the biophysical

scrutinized. The study revealed that 80\% of the
surveyed fishermen are at a medium to high level of
vulnerability due to changes in the distribution of key
commercial species, which influences the productivity
of their traditional fishing sites. Their vulnerability
is primarily attributed to low usage of fishing
technologies, the boat engine's limited propulsion
capacity, and a lack of diversity and sustainability in
fishing gear. These elements increase their reliance on
fishing sites close to the coast (approximately 3 km to
5 km from the shoreline), resulting in a low adaptive
capacity for the fishermen. The dominant factor driving
the sensitivity component was the economic significance
of the fishing gear and the fact that the gear could be
more diverse and durable. These findings provide a

The orchid dottyback Pseudochromis fridmani is a
valuable and popular marine ornamental fish, but
scientific reports on its baseline biology, especially
the egg filial cannibalistic behaviour, are scarce. The
present study documented key aspects of reproductive
biology and early ontogeny of P. fridmani in captivity,
including reproductive behaviour, patterns of spawning
and filial cannibalism throughout a 12-month period by
seven pairs of brood fish, as well as the embryonic and
larval development. The results showed that the captive
spawning of the broodstock pairs generally occurred
every 5--11 days, most commonly every 6--8 days,
throughout a year. Despite feeding the brood fish to
satiation throughout the data collection period, the
average monthly rate of egg filial cannibalism reached
55 {\pm} 37\%, but the cannibalism frequency appeared
to be pair-specific. The egg incubation duration was
approximately 96 h at 27 {\pm} 1 {$^\circ $}C, and the
development of embryos from cleavage, blastula,
gastrula, and segmentation to the pharyngula stage is
herein described in detail. The newly hatched P.
fridmani larvae possessed important structures and
organs for first feeding, including pigmented eyes,
developed jaws, and a straight-tube gut. The 0 to 14
days post-hatching (DPH) period appeared to be an
important larval stage, as P. fridmani larvae were
observed to complete major changes in morphology, gut
development, and phototactic behaviour by 14 DPH. Under
the culture conditions of this study, the earliest
transition to the juvenile stage was observed on 31
DPH, and the majority of fish became juveniles by 56
DPH. The results of this study inform baseline
aquaculture production protocols and direct future
research, particularly to reduce filial cannibalism
through broodstock management and to improve larval
culture through supporting the early ontogenetic
development of P. fridmani. Additionally, these

review was conducted on the helminths parasites of
freshwater fish in the context of species introduction
and a total of 199 publications were retrieved between

when a new fish species arrive in a recipient area.
Non-native fish hosts can co-introduce their parasites
without transmitting them to native fish (e.g., the
case of North American Centrarchidae and their
Monogenea parasites). Another possible outcome is the
transfer of these parasites to the native fish fauna
(spillover, e.g., the cases of the Nematoda
Anguillicola crassus Kuwahara, Niimi \& Itagaki, 1974
and the Monogenea Gyrodactylus salaris Malmberg, 1957).
Reciprocally, non-native fish hosts may acquire
parasites in their new distribution range whether these
parasites are native or were previously introduced
(e.g., the cases of Ponto-Caspian Gobiidae and the
Chinese sleeper Perccottus glenii Dybowski, 1877).
Acquired parasites can then be spilled back to the
native fauna. This phenomenon is of particular interest

the findings indicate that the weight gain rate (WGR),

whereas the FM group had the lowest levels. Conversely,
the malondialdehyde (MDA) content showed the opposite
trend. Both dietary CHL and CAP promoted the digestive
enzyme activities of L. vannamei, with dietary CAP
having a more pronounced promotional effect. An
analysis of alpha diversity indicated that the
consumption of dietary CHL substantially enhanced the
abundance and diversity of microbiota in the intestinal
tract of L. vannamei. Furthermore, the dietary CHL
significantly increased the colonization of
immune-associated beneficial bacteria and inhibited the
colonization of pathogenic bacteria in the intestinal
tract of L. vannamei, whereas dietary CAP mainly
increased the colonization of growth-associated
beneficial bacteria. Functional predictions showed that
different dietary protein sources affect various

vannamei, and some functions, including signal
transduction, cell motility, and the immune system,

abstract = "The effect of thermophilic species invasion in the
eastern Mediterranean is well-noted in the literature.
During the last decade in western Greek waters,
small-scale fisheries (SSF) catches exhibit increased
relative contribution of rabbitfishes, which have
originated from the Red Sea and inhabited the country's
southeastern part since the Second World War. This
study has used quantitative and qualitative information
to assess the short-term economic effect of the
rabbitfishes' expansion in the SSF m{\'e}tier targeting
the indigenous thermophilic parrotfish in the South
Ionian Sea. The short-term micro-level negative
economic effects of the rabbitfishes' invasion and the
corresponding adverse effects on fishers' economic
wealth have been estimated. The results indicate
attitudinal differences among fishers, although their
local ecological knowledge may enable them to avoid
rabbitfishes' hot spots and mitigate the respective
economic losses, that particularly for smaller SSF
vessels already seem to be quite important. As climate
warming may further facilitate the expansion of
rabbitfishes, outcompeting parrotfish, the latter
m{\'e}tier may eventually become economically
unsustainable. Fine-scale analysis at the m{\'e}tier
level enables addressing the specificities of
social-ecological systems and can contribute to
informed and more effective decision making related to
SSF, which is an important building block of
Mediterranean coastal communities.",

mathematical lipid correction for white muscle tissue

ecological value. Lipid extraction was conducted on
yellowfin tuna white muscle tissue (C:N range:
2.96--6.49), and both linear and non-linear lipid
correction models for {\delta} 13 C were fitted and
assessed. Lipid extraction increased {\delta} 13 C, and
to a lesser extent, {\delta} 15 N values in yellowfin
tuna white muscle tissue, but had no effect on {\delta}
34 S. Both non-linear models provided better fits to
the data than the linear model, suggesting an
asymptotic relationship between C:N and

abstract = "The aquaculture production of pikeperch has reached
commercial scale in a number of European countries, but
the high mortality of early life cycle stages and minor
understanding of nutritional requirements are still
major bottlenecks. To investigate the fate of fatty
acids during early development, weaning and rearing,
pikeperch larvae and juveniles from a commercial
recirculating aquaculture system (RAS) were sampled
over 2 months for morphometric data, as well as fatty
acid composition, with a total of 6 sampling days, with
four to five replicates per sampling day and between 1
and 25 pikeperch larvae per individual sample,
depending on larval biomass. The biomass of sampled
pikeperch larvae varied from 0.1 to 420 mg (dry mass
DM), depending on the age of the larvae, and the
initial length of the pikeperch larvae was about 4.5
mm. Our data confirm that, accompanied by an
exponential increase in dry mass, total fatty acids
(TFAs) in larval tissues increased with the beginning
of exogenous feed uptake and were depleted between days
13 and 25 post hatch, most likely associated with the
weaning and metamorphosis of the larvae. We conclude
that all fatty acid classes may serve as metabolic fuel
during metamorphosis, but the ultimate fatty acid
composition is strongly impacted by the available feed.
The chosen diet probably caused a lack of
alpha-linolenic (18:3n-3; ALA) and docosahexaenoic acid
(22:6n-3; DHA) during larval development and a shortage
of vaccenic (18:1n-7), alpha-linolenic (18:3n-3; ALA)
and arachidonic acid (20:4n-6; ARA) in juvenile
pikeperch. This led to low DHA/EPA ratios 13 days post
hatch, a high EPA/ARA ratio at days 41 and 56 post
hatch and a fluctuating ratio of alpha-linolenic acid
to linoleic acid (18:2n-6; LA). A temporary lack of
essential fatty acids can cause dysfunctions and
eventually mortalities in pikeperch larvae and
juveniles. Despite high larval growth rates, the
biochemical composition of the first fed Artemia and
microdiets was most likely not sufficient and in need
of improvement. We suggest that deficiencies must be
compensated, e.g., through the substitution of the
offered Artemia with more suitable live feed organisms,
such as freshwater rotifers, and the enrichment of
current microdiets in order to prevent high mortalities
during pikeperch rearing and weaning.",

80\% of the past 6 h, the system will assign the
keypoint from the DeepLabCut tool to the lobster hip.
The process primarily concentrates on the S3--S5 stage
to identify the variation in the hatching spot. At the
end of this process, the system will re-import the
optimized Yolov5s to detect the presence of an
independent shell, S6, inside the tank. The optimized
Yolov5s embedded a Convolutional Block Attention Module
into the backbone network to improve the feature

evaluated by evaluation metrics, comparison studies,

abstract = "The warming and acidification of surface waters as
predicted by the IPCC leads aquatic species to face
major multifaceted changes in their environment.
Although teleosts have efficient regulatory systems to
cope with these changes, such changes clearly have the
potential to impact their physiological functions.
Hence, it is crucial to estimate the ability of teleost
fishes to cope with multi-stresses to predict how they
will deal with future environments. In this context, we
investigated the joint effect of warming and
acidification on three-spined stickleback (Gasterosteus
aculeatus) from the juvenile stage to adulthood,
focusing on parameters linked to growth, sexual
maturation, and reproduction. Juvenile sticklebacks
were split in 2 climate scenarios: a ``Current''
scenario corresponding to the current seasonal
physico-chemical parameters of the water of the ``Rade
de Brest'' in France, and a ``RCP8.5'' scenario with a
warming of 3 {$^\circ $}C and an acidification of 0.4
pH units. After 7 months, fish in the RCP8.5 scenario
reached the same size and mass as those in the Current
scenario, but they needed greater amounts of food to
reach satiety. Furthermore, the mortality rate over the
experiment was higher in the RCP8.5 scenario. Muscle
lipid content, an indicator of energy reserves, was
lower in females in the RCP8.5 scenario, suggesting an
increased need for energy to maintain homeostasis and
other physiological functions or a divergence in energy
allocation strategy. Moreover, females exhibited lower
sexual maturation and egg quality under the RCP8.5
scenario, which could have contributed to the lower
fertilisation rate observed. Males were more resilient
to the RCP8.5 scenario, exhibiting only a trend for
lower kidney somatic index scores. Altogether, these
results suggest a delay and/or an inhibition of
gametogenesis and maturation in fish in warmed and
acidified waters. The analysis of blood sex steroid
concentrations, brain gene expression profiles, and
physiological indexes did not allow us to discriminate
between a delay and an inhibition of maturation in the
RCP8.5 scenario. Overall, these findings clearly
indicate that there is a long-term global impact of
combined acidification and warming on the mortality and
reproductive performance of three-spined stickleback.",

how surface ice and light affected the anti-predator

lota Linnaeus, 1758) and northern pike (Esox lucius
Linnaeus, 1758) at 4 {$^\circ $}C in experimental
flumes. Trout had lower foraging and swimming activity
and spent more time sheltering when predators were
present than when absent. In daylight, trout's swimming
activity was not affected by predators, whereas in
darkness trout were less active when predators were
present. Trout consumed more drifting prey during the
day when ice was present, and they positioned
themselves further upstream when under ice cover,
regardless of light conditions. Trout stayed closer to
conspecifics under ice, but only in the presence of
pike. Piscivorous fishes thus constitute an essential
part of the predatory landscape of juvenile trout in
winter, and thus loss of ice cover caused by climate
warming will likely affect trout's interactions with

decrease in the frequency of sampling could
dramatically affect the determination of the major

to investigate the effect of water spinach rafts on the
water quality, antioxidant system, non-specific immune
response, and growth performance of red tilapia and the
carbon balance of payments. Red tilapia is
characterized by its high adaptability to different
production environments and food sources, as one of the
most productive fish in aquaculture, and is well
accepted in the market due to its nutritional and
organoleptic characteristics. The experiment lasted for
nine weeks and included two systems: the red
tilapia-water spinach raft aquaponics (AP) system with
10\% cover ratio with water spinach floating beds, and
the aquatic monoculture (AM) system with only red
tilapia. The total phosphorus (TP), total nitrogen
(TN), and nitrate nitrogen (NO {$-$} 3 -N) in the AM
were higher than those in AP from the fifth to ninth
week. On the second, third, fifth, and sixth weeks, the
ammonia nitrogen (NH 4 + -N), in the AM was higher than
those in the AP. From the seventh week, the pH of the
AM was significantly lower than the AP, while the
nitrite nitrogen (NO {$-$} 2 -N) was significantly
higher than the AP. The water quality index of the AP
was better than that of the AM, indicating that water
spinach can remove the nutrients from aquaculture water
bodies. The average daily gain and specific growth rate
(SGR) of fish in AP were higher than those in the AM.
The acid phosphatase (ACP), alkaline phosphatase (AKP),
and catalase (CAT) activities in the hepatopancreas of
red tilapia in the AP were also significantly higher
than those in the AM, while the malondialdehyde (MDA)
in the AP was lower than the AM. The serum ACP and CAT
of red tilapia in the AP were also higher than those in
the AM, while the MDA of fish in the AP was lower than
the AM. The results showed that both the experimental
group and the control group were carbon sources and
released greenhouse gases into the atmosphere, but the
total carbon emissions of the red tilapia and the water
spinach symbiotic system in the experimental group was
significantly lower than that of the control group (p
{$<$} 0.05). These results demonstrated that the
application of water spinach rafts in aquaponics can
not only improve the water quality, but also improve
the growth performance, antioxidant system and
non-specific immune responses of red tilapia, while
promoting the utilization of organic matter in the
aquaculture system, improving the ecological benefits
in terms of the carbon income and expenditure.",

added. The control group was fed 100\% feed, while the
BFT experimental groups were fed microbial flocs along
with 75\% feed. The results revealed that the water
quality parameters were affected by the carbon sources,
but were adequate for normal fish welfare, and the
biofloc volume was higher (28.94) with the TF carbon
source. The growth performance, such as weight gain
(98.61), survival (99.01), and improved feed conversion
ratio (FCR) (1.69), was recorded in BFT + TF.
Significant improvements in WBCs, HCT, HB, lymphocytes,
plasma proteins, albumin, and non-specific immune
factors (lysozyme activity, immunoglobulins levels, and
ACH50) were observed in biofloc-reared fish with
tapioca flour as the carbon source compared to the
control and sugarcane molasses groups. Moreover,
significant increases in catalase (CAT) and superoxide
dismutase (SOD) were found in the biofloc-reared fish
with different carbon sources. In conclusion, the use
of BFT + TF was found to affect improving the water
quality, growth, hematology, immunity, and antioxidant
status of juvenile Tilapia.",

species. There were four and eight broad niche species
in spring and autumn, respectively. The ranges of niche
overlap values were 0.001--0.91 in spring and 0--0.87
in autumn, indicating that the species differed and
were similar in their ability to utilize resources,
survive in habitats, and prey. According to the
variance ratio and statistic value W, the main fishes
in spring showed a significant positive association,

Third, we assess how life history and physiology
affects catchability and loss of genetic diversity.
Finally, we discuss how coinciding abiotic and biotic
factors influence the intensity of genetic loss. We
find a multitude of these factors could be interacting
to influence how results are perceived and how intense
the loss of genetic diversity can be. Future studies
should carefully consider the methodology of genetic

(RNAi) was used to silence the luxR gene, and the
pathogenicity of wild-type and luxR -RNAi strains of P.
plecoglossicida, as well as the immune response of

in mortality rates in artificially infected Epinephelus
coioides compared to the wild-type strain.
Transcriptome analysis revealed that the host
transcriptome, particularly in the spleens of infected
Epinephelus coioides, was markedly altered by the
silencing of the luxR gene in the mutant strain.
Tilapia infected with the luxR -RNAi strain exhibited
altered immune defenses, with changes in gene
expression primarily in the NOD-like receptor (NLR)
signaling pathway. These results suggest that the luxR
gene plays a crucial role in the host's resistance to
pathogen invasion, and reducing its expression could
decrease quorum sensing (QS) signals while increasing
the expression of the IL-1{\beta} gene in the host's
NLR pathway. This effect may lead to a pro-inflammatory
response that enhances the immune response to
infection. Further investigation of these mechanisms
may lead to innovative approaches to treating bacterial

behavior, including reproduction, aggregation, hazard
recognition and food location. To gain a better
understanding of chemical communication in fish
produced by density changes, this study analyzed the
metabolites released by turbot (Scophthalmus maximus)
under different stocking densities. The experiment was
conducted at low (LD: 3.01 kg/m 2), medium (MD: 6.62
kg/m 2) and high (HD: 10.84 kg/m 2) densities for 15
days. High-throughput non-targeted metabolomics
(LC-MS/MS) was used to identify variations in
metabolites released into the aquatic environment by
turbot at different densities. Results showed that 29
and 47 metabolites were significantly upregulated in
the MD and HD groups, respectively, compared with the
LD group. Among them, hexadecanedioic acid, xanthine,
phenethylamine, proline and styrene were significantly
upregulated in the MD vs. LD, HD vs. MD and HD vs. LD.
The VIP diagram of OPLS-DA alignment showed that
phenethylamine was the most important metabolite shared
by MD vs. LD, HD vs. MD and HD vs. LD. Key gene changes
in the GH/IGF-1 signaling pathway, HPI axis of turbot
were studied using qRT-PCR for density treatment. The
results demonstrated that the expression of GH, GHR and
IGF-1 was significantly lower, while the expression of
CRH and ACTH was higher in the HD group. Additionally,
plasma levels of cortisol, glucose, triglycerides and T
3 were also highest in the HD group compared with the
LD and MD groups. Phenylethylamine concentration was
positively correlated with the HPI axis and negatively
correlated with the GH/IGF-1 signaling pathway. To
investigate the impact of phenethylamine accumulation
on turbot, an acute treatment experiment with
phenethylamine was set up. Its concentration in the
aquatic environment was set at 0 (CON), 10 {$-$7} (LP)
and 10 {$-$5} (HP) mol/L via exogenous addition, and
turbot were exposed to these environments for 2 days.
There was a high degree of concordance between the
GH/IGF-1 signaling pathway (GH, GHR, IGF-1), HPI axis
(CRH, ACTH) and plasma physiological changes (cortisol,
glucose, triglycerides, T 3) in the
phenethylamine-treated group and the density-treated
group. Therefore, accumulation of phenethylamine with
increasing stocking density may be a potential cause of
density stress. Phenylethylamine has a dose-dependent
and trace effect as a pheromone.",

abstract = "In 2017, Uganda's small-scale inland fisheries
underwent a significant transformation, shifting from
local co-management to state military enforcement owing
to ineffective enforcement of regulations and declining
exports. Employing a mixed-methods approach and
blending qualitative and quantitative data, we assessed
the impact of military intervention on Lake Victoria's
Nile perch fishery, focusing on fishing effort, catch,
and exports. Our findings indicate that military
operations adhered to regulations, gaining primary
support from key stakeholders, specifically motorized
fishing operators. Consequently, between 2016 and 2020,
legal fishing activities experienced substantial
growth. By 2021, approximately 90\% of Nile perch
catches were made by motorized vessels using longlines
and gillnets, despite a declining trend in
catch-per-unit effort. Between 2015 and 2021, the Nile
perch fishery saw changes: boat seines made up about
5\% of motorized fleet catches in 2021, while catches
in paddled vessels increased from 20\% to over 50\%,
suggesting a potential role in the growing longline
fishery. Therefore, the current management approach
does not increase catches or exports compared with the
co-management period. The observed decline in
catch-per-unit effort among motorized gillnets suggests
overcapacity. Further research is needed to comprehend
the broader sociological and ecological impacts of the
present enforcement strategy for sustainable fishery
management.",

significant reduction in total errors (courtship

finding was the net size at which 50\% of the minimum

0.9. Salinity was identified as the principal factor
during both periods. The salinity niche of Acropoma
japonicum and the primary productivity niche of
Sciaenidae were identified as the most restricted
factors. The total distribution area of potentially
suitable regions for major fish catches extended
between {106$^\circ $}30{\prime}--109{$^\circ

reduced reproductive fitness, and a greater left side

(Fulton's K), internal measures of condition
(hepatosomatic index, HSI) and reproductive fitness
(gonadosomatic index [GSI], total oocyte count, and
oocyte mass). In 2015, measurements of head length, jaw
length, eye diameter, pectoral fin length, and pelvic
fin length were made on both sides of each fish for
assessing degree of FA. We observed declining condition
with fish size, increased liver size, and reduced
oocyte counts and oocyte size in female brook
stickleback in SFWR relative to those from Garvin
Brook. SFWR females had significantly higher FA than
Garvin females for all structures assessed, except
pelvic fin length. FA also was slightly higher for all
structures in SFWR males compared to Garvin males, but
differences were not significant. A composite FA index
combining all measurements from an individual fish into
a single value displayed highly significant differences
for female fish (SFWR FA {$ > $$ >$ } Garvin FA), but
not for male fish (SFWR FA = Garvin FA). Exposure of
brook stickleback to reduced water quality in SFWR

The growth performance, intestinal morphology, enzyme
activity, and microbial communities were compared

that the higher stocking density condition exhibited an
increased weight gain rate and specific growth rate
during the developmental phase of the juvenile M.
salmoides. Moreover, remarkable increases in villi
height, villi width, and muscular layer thickness were
observed. Additionally, this elevated stocking density
condition also enhanced the activity of intestinal
antioxidant enzymes, consequently improving the
structural integrity of the intestine and augmenting
the digestive and absorptive capacities of the juvenile
M. salmoides. With regard to the intestinal microbial
community, the dominant phyla detected were Firmicutes
and Proteobacteria. However, under the higher stocking
density condition, there was a significant upsurge in
the abundance of Mycoplasma. Consequently, it is
advised to mitigate the abundance of such pathogenic
microorganisms through the regulation of the water
environment during the aquacultural process. Drawing
from recent investigations on the impact of various
factors on the intestinal microbiota of M. salmoides,
it can be deduced that the composition of the

Feed texture (hard and dry pellet, HDP; soft and moist

duration. The resulting feed waste was categorised as
either feeding-related waste (FRW) or

the FRW increased with increasing pellet diameter and
pellet length. The increase in FRW corresponded with a
decrease in NFRW, particularly for HDP, resulting in no
difference in total feed waste in any treatment
investigated. Thus, even with improved feeding
efficiency with small feed dimensions, feed intake was
not improved. Feed leaching rate decreased with
increasing pellet size, suggesting a more rapid decline
in feed attractiveness for smaller pellets. This
finding indicates that currently a counteractive

gradually migrated from the dorsal sides to the
mid-ventral area of the ovary, eventually maturing into
eggs. In the testis, the primary and secondary
spermatocytes appeared at 15 and 30 DAB, respectively,
preceding the formation of the testicular lumen (50
DAB). The testis was observed to consist of a single
large germinal compartment. Under captive breeding
conditions in Northern China, the pot-bellied seahorse
demonstrated year-round breeding capability, with each
male producing approximately 100--150 larvae. The

into seahorse aquaculture and enhance understanding of
the unique reproductive strategy employed by

abstract = "Fishes are ecologically important organisms that have
long lifespans, high mobilities, and diverse trophic
levels. Due to their importance, fishes are used as
bioindicators for monitoring aquatic environments. One
method for monitoring fishes is based on environmental
DNA (eDNA), which are the deoxynucleic acids released
by organisms into the environment. However, there has
been a problem with false positives because eDNA is
relatively stable in the environment and could even
likely represent dead or non-inhabiting organisms. To
address this weakness, environmental RNA (eRNA), which
degrades more rapidly than eDNA in the environment, can
be utilized to complement eDNA. But, to date, few
studies have used eRNA for freshwater fish monitoring.
In this study, to determine the relative usefulness of
eDNA and eRNA metabarcoding in freshwater fishes, we
performed eDNA and eRNA metabarcoding on 12S rRNA
targeting fish using water samples that were collected
from three locations in the Han River. We then
calculated the sensitivity and positive predictivity of
this approach by comparing our data to the previous
specimen capture survey (PSCS) data from the last six
years. The results showed that 42 species were detected
by eDNA and 19 by eRNA at the three locations. At all
locations, compared to the PSCS data, the average
sensitivity was higher for eDNA (46.1\%) than for eRNA
(34.6\%), and the average positive predictivity was
higher for eRNA (31.7\%) than for eDNA (20.7\%). This
confirmed that eDNA metabarcoding has the advantage of
broadly determining species presence or absence
(including those that are no longer present or dead),
but it also generates false positives; meanwhile, eRNA
metabarcoding reports living fish species, but detects
fewer species than eDNA. Combining eDNA and eRNA
therefore emphasizes their advantages and compensates
for their disadvantages, and conducting this may
therefore be useful for identifying false positives and
monitoring the fish species that are actually present
in the environment. This metabarcoding technique can be
used in the future to provide insights into the aquatic
environment and the monitoring of fisheries.",

expression patterns and regulatory mechanisms in their

genes with significantly different expression levels
were extracted for functional verification. The most
genes with differences in expression (DEGs) were found
in comparisons of the winter and summer samples. Gene
enrichment analysis based on Gene Ontology and Kyoto
Encyclopedia of Genes and Genomes terms showed that
these DEGs were mainly involved in immune and metabolic
pathways, and they had significant effects on oxidative
stress, body metabolism, and protein synthesis in
Neptunea cumingii. Further screening of DEGs identified
thirty-four genes related to temperature regulation,
comprising thirteen genes with roles in innate immunity
in shellfish, twelve genes related to oxidative stress,
and nine genes related to protein synthesis and energy
metabolism. Eleven DEGs were randomly selected for qPCR
verification, and the results were consistent with the
transcriptome analysis results. In summary, the
transcriptome results differed significantly between
seasons in the gill tissues of Neptunea cumingii. The
expression levels of immune regulatory genes could be
promoted in Neptunea cumingii during the high
temperature season, whereas the expression of these
genes may be inhibited in the low temperature season.

from predation in ways generally similar to other fish

appears to mimic GZ for predation reduction. Like a

carbon to the aquaculture system to improve water

and efficiency by combining it with other aquaculture
technologies, such as aquaponics and vertical

the role of bZIP transcription factors in mediating the
molecular responses to nitrite stress in the LMB
spleen. We identified 120 bZIP genes in the LMB genome
using bioinformatics analysis and divided them into 11
subgroups based on phylogenetic relationships. Under
nitrite stress, the bZIP_XI subgroup was upregulated,
suggesting the activation of the stress response in the
LMB spleen. Cellular pathway analysis revealed
enrichment of pathways related to stress response, DNA
repair, apoptosis, and autophagy. Co-expression network
analysis highlighted bZIP_XI members such as
msabZIP_49, msabZIP_12, msabZIP_39, and msabZIP_116 as
potential key regulators. These transcription factors
likely modulated the expression of stress-related genes
like VCAM1, POLE3, and BMP1. Conserved binding motifs
in the promoters of these genes may support regulation
by bZIP_XI. Furthermore, bZIP_XI members correlated
with immune cell infiltration in the spleen,
potentially regulating immune-related genes like BCL2L1
and SELE. Homologs of bZIP_XI in other fish species
exhibited similar expression patterns under stress.
Overall, this study implicates the bZIP transcription
factor family, notably the bZIP_XI subgroup, in
orchestrating the molecular response of the LMB spleen
to nitrite toxicity by regulating stress response
pathways and immune function. These findings provide

abstract = "A better understanding of trophic interactions between
hardhead catfish (Ariopsis felis) and gafftopsail
catfish (Bagre marinus) is crucial for developing
multi-species management strategies for the northern
Gulf of Mexico (GOM). These two species are often
aggregated in food web models; however, limited data
are available to substantiate this approach. Therefore,
the present study aimed to describe the dietary habits
of hardhead catfish and gafftopsail catfish using
analysis of stomach contents aided by DNA barcoding.
Hardhead (n = 693) and gafftopsail (n = 655) catfish
were sampled in the northern GOM from 2015--2019 using
both fisheries-dependent and -independent techniques.
The average percent number (\%N), average percent mass
(\%M), prey specific number (\%PN), prey specific mass
(\%PM), and prey-specific index of relative importance
(\%PSIRI) were computed to quantify prey species. The
stomach content analysis identified distinct
differences in diet between hardhead and gafftopsail
catfish. Crustaceans were the most important prey for
hardhead catfish, while gafftopsail catfish showed a
significantly broader dietary breadth and were
primarily piscivorous. Multivariate analyses indicated
that the location of capture explained the greatest
amount of diet variability for both species. These
findings address fundamental knowledge gaps regarding
the dietary habits of hardhead and gafftopsail catfish
in northern GOM ecosystems.",

sites during the November--December 2018 low-flow
period. In total, 39 fish species from nine orders and
14 families were documented. Among these, 10 species
were alien to the basin (986 individuals; 15.7\%). Four
species were the most abundant alien species and
primarily in impounded, downstream reaches. Redundancy
analysis (RDA) was conducted to identify the extent of
changes in alien fish assemblages with environmental
parameters. RDA1 and RDA2 accounted for 36.24\% and
25.33\% of the variation of alien species,
respectively. Altitude, depth, electrical conductivity,
water temperature, turbidity, dissolved oxygen, and
river width were the most significant parameters
affecting alien species distributions. We present a
dual-pathway cause-and-effect hypothesis proposing that
alien fish species presence causes declines in the
ecological status of native fish communities. We then
explore how human-induced aquatic ecosystem degradation

on fish cognitive evolution to increase our
understanding of the evolution of the enormous
diversity of cognitive abilities that exists in fishes.
One important but understudied aspect of cognitive
evolution is sexual dimorphism in cognitive abilities.
Sex-specific variation in brain region morphology has
been proposed to be an important mechanism in this
context. However, it is also common to find
sex-specific variation in behavior and cognition
without associated differences in brain morphology
among the sexes. The telencephalon is the major
cognitive center in the vertebrate brain and variation
in telencephalon size has been associated with
variation in cognition. Here, we utilize recently
developed guppy artificial selection lines with ca.
10\% differences in relative telencephalon size to
investigate whether similar responses to selection of
the size of this region may affect cognitive abilities
differently in males and females. To that end, we
compared two ecologically relevant aspects of
cognition, detour learning and binary spatial
discrimination. We tested the significance of the
interaction between telencephalon size and sex, and we
found no sex-specific effects of evolutionary increases
in telencephalon size in the cognitive abilities
tested. This study indicates that no clear cognitive
sex-specific effects occur in response to rapid
selection of telencephalon size. We suggest that future

from an aquarium in the North Sea Oceanarium. They have
been in the aquarium for around two months and were
originally collected in a highly eutrophicated marine
fjord system. They were individually placed in an
observation aquarium, fed with krill, given 10 min to
forage, and observed by video cameras. The video films
were analysed to study stickleback predation behaviour.
Experiments were repeated with four different turbidity
treatments, ranging from a mean of 0.034 up to 10 NTU
(nephelometric turbidity unit). Bentonite clay was used
as a turbidity-increasing substance. A statistically
significant difference in foraging behaviour and
activity between the turbidity treatments was observed.
The test subjects were found to lunge less for prey and
had a higher feeding latency with increasing turbidity.
Additionally, they were less active with increasing
turbidity. The behavioural instability estimated as a
variation in feeding latency increased with increasing
turbidity but decreased at the highest turbidity value.
Our study indicates an effect of turbidity-increasing

compare the efficacy of three models, specifically the
General Linear Model (GLM), the Generalized Linear
Mixed Model (GLMM), and the spatio-temporal GLMM
(VAST), in the CPUE standardization for Pacific sardine
fishery in the NPO, with the ultimate goal of
identifying the most appropriate model. An influence
analysis was applied to analyze the impact of
individual variables on the disparity among
standardized and nominal CPUE, and the main explanatory
variables influencing standardized CPUE were
identified. A coefficient--distribution--influence
(CDI) plot was generated to analyze the impact of the
different models on the annual standardized CPUE.
Additionally, a simulation testing framework was
developed to evaluate the estimated accuracy of the
three models. The results indicated that the
standardized CPUE and the nominal CPUE exhibited
similar trends between 2014 and 2021 for the three
models. Compared to the GLM and the GLMM, the VAST
demonstrates larger conditional R 2 and smaller
conditional AIC, indicating a better performance in
standardizing the CPUE for Pacific sardines due to its
consideration of spatial and temporal variations. The
interaction terms within the three models exert
significant influences on the annual standardized CPUE,
necessitating their inclusion in the model
construction. CDI plots indicate that the
spatio-temporal influence of the VAST model exhibits a
smaller variation trend, suggesting that the VAST is
more robust when standardizing the CPUE for Pacific
sardines. Simulation testing additionally demonstrated
that the VAST model displays smaller model root mean
squared error (RMSE) and bias, establishing it as the
superior performer for standardizing CPUE. Our results
provide a theoretical basis for the scientific
management of Pacific sardines in the NPO and can be
extended to CPUE standardization for other small
pelagic fish species worldwide.",

most extensively studied insect protein source in
shrimp nutrition. However, both the availability and
prices of BSFLM are still a constraint for its
widespread use as an ingredient in animal feeds. The
present study investigated the growth and economic
performance of post-larval (PL) P. vannamei fed nursery
diets with a progressive replacement of fish meal (FML)
for BSFLM at 0, 25, 50, 75, and 100\%. These
replacements corresponded to a dietary inclusion (\% of
the diet, as-is) of FML and BSFLM of 16.50 and 6.33\%,
11.00 and 13.04\%, 5.50 and 19.74\%, and 0 and 26.46\%,
respectively. A total of 102,647 shrimp at the age of
PL15 with 2.7 {\pm} 0.2 mg body weight (BW) were
stocked in fifty 1.5 m 3 tanks under 1369 PLs/m 3 (2053
{\pm} 33 PLs/tank) and reared for 42 days. Final shrimp
survival (90.5 {\pm} 7.6\%), daily weight gain (14.7
{\pm} 1.1 mg/day), and apparent feed intake (0.67 {\pm}
0.03 g of feed per stocked shrimp) were unaffected by
dietary treatment. The highest gained yield (791 {\pm}
52 and 776 {\pm} 38 g/m 3) and final BW (621 {\pm} 7.2
and 632 {\pm} 7.2 mg) were attained when FML was
replaced for BSFLM at 50 and 75\% with the lowest at
0\% (726 {\pm} 34 g/m 3 and 598 {\pm} 8.1 mg,
respectively). Shrimp fed diets with 0 and 100\%
replacement of FML exhibited the highest feed
conversion ratio (1.25 {\pm} 0.04 and 1.24 {\pm} 0.08)
compared to those fed a diet with 50\% (1.16 {\pm}
0.06). At a price of USD 2.00/kg, BSFLM demonstrated a
favorable ROI (return of investment) when compared to
FML, irrespective of the replacement level. With 25 and
50\% replacement, BSFLM remained cost-competitive up to
3.50 USD/kg. At 75\% FML replacement, there were no
significant differences in ROI with a price range of
2.00 up to 3.04 USD/kg. At full replacement, ROI
dropped significantly at a BSFLM price of 2.50 USD/kg
and beyond. It can be concluded that FML can be fully
replaced for BSFLM in well-balanced nursery diets for
P. vannamei. Although the full replacement of FML for
BSFLM was successfully accomplished, the competitive
ROI was sustained only when the price of BSFLM did not
exceed 3.04 USD/kg at its dietary highest inclusion of
19.74\%. Further research may be necessary to fine-tune
cost-effective inclusion levels of BSFLM to optimize
the economic outcomes while considering the fluctuating

traditional Chinese medicine, as well as for the
aquarium trade as ornamentals and curiosities. To
balance market demand and reduce pressure on wild

seahorse cultivation. Skeletal development plays a
crucial role in fish fry culture, affecting external
morphology, feeding, and movement. This study
investigated the ontogeny allometry, timing, and
progression of skeletal development in H. abdominalis
from DAB (day after birth) 1 to DAB 100 under
mass-scale captive breeding conditions in north China.
The results of this study revealed the growth rate was
significantly increased between DAB 30 and DAB 54.
Allometry analysis revealed that in the early stage,
the head, trunk, and tail demonstrated almost isometric
growth. However, in the later stage, the head and trunk
exhibited negative isometric growth, whereas the tail
displayed positive isometric growth. Skeletal staining
results showed that newborn seahorses do not have
ossified bones until DAB 11 (SL 28.14 {\pm} 2.94 mm).
Ossification was primarily observed in the jaw region
and the tubular nasal structure of the cranium, which
indicated the importance of the early development of
feeding organs. The initial formation of ossified
vertebral columns was observed at DAB 13 (SL 26.48
{\pm} 0.63 mm), with the complete ossification of all
vertebrae occurring by DAB 45 (SL 54.87 {\pm} 4.70 mm).
Furthermore, the cranium, rings, and plates were all
fully ossified by DAB 30. Ossification of the fins
began at DAB 23 (SL 31.27 {\pm} 4.05 mm). However,
neither of them were fully ossified by DAB 100. The
pelvic fin and the complete structure of the caudal fin
were not observed, possibly because of caudal fin ray
structure degeneration within the pouch. In addition,
no skeletal deformities were observed in all the tested
samples. The results of this study provide valuable

study utilizes data from the Tonga Tuna Longline
Fisheries spanning from 2002 to 2018. The data are
employed to extract information about the spatial

marine environmental variables covering both sea

between the distribution of fishing effort and marine
environmental factors. Furthermore, it examines and
analyzes the ecological niche occupied by tuna longline
vessels in high-sea environments. The outcomes of the
factor analysis indicate that the most important
factors influencing the fishing efforts of tuna
longliners are the dissolved oxygen content at the sea
surface and latitude. These two factors contribute
significantly, accounting for 19.06\% and 18.62\% of
the fishing efforts of vessels, respectively, followed
by distance to ports, longitude, and dissolved oxygen
at 100 m depth, contributing 10.77\%, 7.07\%, and
6.30\%, respectively. The sea surface chlorophyll,
ocean current at 100 m depth, and mixed layer depth
contributed the least, 3.63\%, 2.13\%, and 1.72,
respectively. In terms of space and time, tuna
longliners are more likely to operate in the
18--{22$^\circ $} S latitudinal and 172--{178$^\circ $}

the months from March to August. The spatial
distribution of the fishing efforts modeled for fishing
vessels in 2018 is predicted to have good spatial
distribution with the actual fishing efforts of these

Recently, the presence of black spot disease,
associated with a digenean fluke of the genus
Scaphanocephalus, has been observed in specimens of
Xyrichthys novacula on the island of Ibiza (Balearic
Islands). The aim of the present study was to evaluate
the antioxidant and immune response in both the skin
mucus and spleen of X. novacula depending on the degree
of infection by Scaphanocephalus sp. The specimens were
captured in a control area, without the presence of the
parasite, and in an affected area, classifying the fish
as low infection (1--15 spots) and high infection
({$>$15} spots). As the degree of infection increased,
a decrease in the body condition index was observed.
The activity of the antioxidant enzymes in the
mucus---catalase, superoxide dismutase and glutathione
peroxidase---increased progressively with the degree of
infection. This activation of antioxidant defences was
not enough to prevent an increase in malondialdehyde
levels, an indicator of oxidative damage, in the group
with the highest infection. Similarly, an increase in
immunological parameters---lysozyme, alkaline
phosphatase, myeloperoxidase and immunoglobulins---was
observed in mucus as infection increased. Regarding the
spleen, only an increase in lysozyme activity and
alkaline phosphatase in fish with a greater severity of
infection was observed. In conclusion, as the severity
of Scaphanocephalus sp. infection increased, it induced
an immune and oxidative stress response in skin mucus,
leading to a decrease in overall body condition. The
potential health effects that the ectoparasite may have
on X. novacula populations will require follow-up
studies.",

and select some potential Japanese flounder families
(labeled 2101--2108, established by crossbreeding)
tolerating U. prolifera degradation conditions. Thus, a
60-day U. prolifera exposure experiment was conducted.
The results showed that the contents of Na, K, Mg, and

survival rate of flounder were significantly decreased
under the U. prolifera degradation condition, while the
2101 and 2103 flounder families showed a better growth

total antioxidant capacity (T-AOC), transaminases, and
alkaline phosphatase (AKP) in serum were significantly

activities. Furthermore, U. prolifera degradation
significantly increased superoxide dismutase (SOD)
activity and glutathione (GSH) content while decreasing
catalase (CAT) activity and malondialdehyde (MDA)
content in the liver. Specifically, SOD and CAT
activities of the 2103 flounder family were higher than
the 2101 flounder family and PC group. In addition, the
gill SOD and CAT activities of the 2103 flounder family
were significantly higher than the PC group. Similarly,
the antioxidant-related gene (sod and cat) expressions
were synchronously upregulated or downregulated in the
liver and gills in response to U. prolifera
degradation. These results revealed that U. prolifera
degradation decreased the growth performance and
influenced the antioxidant capacity of Japanese
flounder, while the 2103 flounder family had better
advantages in the U. prolifera degradation condition.
Therefore, the 2103 flounder family could be regarded
as the potential flounder family tolerating U.
prolifera degradation. The increased Fe content in the
U. prolifera degradation water may be one of the main
causes of the physiological alterations observed in
Japanese flounder.",

functionally characterized the STING homolog from the
Chinese giant salamander Andrias davidianus (AdSTING)
for the first time. The open reading frame of AdSTING
encodes a 362 amino acid protein with a predicted
molecular mass of 41.6 kDa, which shares 31.1--46.7\%
of its sequence identity with STING homologs in other
vertebrates. Structural analysis revealed that AdSTING
possesses four predicted transmembrane domains (TMs) at
the N-terminal, and a C-terminal domain (CTD) featuring
a dimerization domain (DD), a c-di-GMP-binding domain
(CBD), and a short C-terminal tail (CTT). Tissue
distribution analysis showed that AdSTING mRNA was
ubiquitously expressed in all examined tissues, with
abundant expression in muscles, intestine, and thymus.
During Andrias davidianus ranavirus (ADRV) infection,
significant up-regulation of AdSTING expression was
observed in the thymus, spleen, and kidney. Upon
different stimuli in vitro, the expression of AdSTING
was significantly induced by ADRV infection or
polyinosin-polycytidylic acid (poly I:C) stimulation,
but no obvious changes were observed during
lipopolysaccharide (LPS) stimulation. Subcellular
localization analysis revealed that AdSTING mainly
localized in the cytoplasm in the Chinese giant
salamander thymus cell line (GSTC) and co-localized
with the endoplasmic reticulum (ER). Luciferase
reporter assays confirmed the ability of AdSTING to
activate the interferon-stimulated response element

overexpression of AdSTING effectively decreased ADRV
infection, as evidenced by the reduction of virus
titers and viral gene expression. Collectively, our
findings underscore the pivotal role of AdSTING in the
antiviral innate immunity of the Chinese giant

abstract = "Photoperiod is one of the most important environmental
cues for organisms, and it plays a crucial role in
regulating feeding, behavior, growth, and metabolism.
However, seasonal photoperiods are often overlooked in
carp culture or experiments, with a poorly understood
effect on lipid metabolism and oxidative stress in
fish. To explore the effects of seasonal photoperiods,
we exposed Huanghe carp (Cyprinus carpio haematopterus)
to summer photoperiod (14 h light:10 h dark) and winter
photoperiod (10 h light:14 h dark) daylight conditions
in an eight-week experiment. Our results suggested that
the winter photoperiod significantly increased the
liver TG level as well as the transcript levels of
genes related to lipid synthesis, indicating that the
lipid metabolism in Huanghe carp liver was enhanced
compared to summer photoperiod conditions, and that
lipid deposition may be responsible for the increase in
body weight level and hepatosomatic index.
Additionally, MDA, GSH, GSH-PX, and T-AOC levels were
significantly elevated in the liver of fish under the
winter photoperiod, suggesting that Huanghe carp
responded to winter photoperiod exposure-induced
oxidative stress in the liver by enhancing the
antioxidant response. Based on transcriptome analysis,
the winter photoperiod activated hepatic autophagy
response and the FOXO signaling pathway in Huanghe
carp. Combined with the correlation analysis, the
Huanghe carp maintains the physiological health of the
liver by activating the FOXO signaling pathway-mediated
cell cycle regulation and autophagy response in
response to oxidative stress during winter photoperiod
exposure. Our study provides the first evidence for the
physiological regulation of the liver in Huanghe carp
under seasonal photoperiod stimulation.",

closely associated with their phenolic content. Then,
juvenile Jian carp (Cyprinus carpio var. Jian, 10.2

that dietary AE increased the growth performance of

abstract = "The Yangtze finless porpoise (Neophocaena
asiaeorientalis asiaeorientalis, YFP) is an endangered
species endemic to the Yangtze River in China, and it
is the only freshwater whale in the genus Neophocaena.
In terms of protection, three effective conservation
strategies exist: in situ conservation, ex situ
conservation, and artificial breeding, all of which
have been implemented by the Chinese government. Of
these, ex situ conservation involves the relocation of
Yangtze finless porpoises to semi-natural waters with
less human interference, and artificial breeding
involves the relocation of Yangtze finless porpoises to
a controlled environment that is more strictly managed.
To compare and analyze the responsive changes in gene
expression of the YFPs between the ex situ and
controlled environments, we performed the RNA
sequencing of blood tissues from these YFPs. A total of
1201 differentially expressed genes (DEGs) were
identified, of which 423 were up-regulated in the ex
situ population and 778 were up-regulated in the
controlled-environment population. Gene enrichment
analysis showed that 1201 DEGs between the ex situ and
controlled-environment populations were generally
enriched for vision-, digestion- and
immune-system-related pathways. Further analysis
revealed that several key immune system pathways, such
as the chemokine signaling pathway and B cell receptor
signal pathway, were activated in the ex situ
population. In addition, the key pathways related to
vision, including phototransduction and the
inflammatory mediator regulation of TRP channels, as
well as the pathways related to the digestive system,
such as protein digestion and absorption and salivary
secretion, were activated in the controlled-environment
population. These results suggest that the ex situ
populations may respond to complex environmental
conditions in semi-natural waters by enhancing their
immune function through the increased expression of
immune-related genes and that the visual function and
protein digestion of the YFPs were improved compared to
those of the ex situ population based on the conditions
of artificial feeding, such as the higher transparency
of the water and regular feeding. This study provides
clues for evaluating the adaptability of YFPs to
different environments and is a useful reference for
future ex situ conservation and artificial breeding.",

critical technologies for large-scale fishery farming
when trying to achieve accurate, green farming and
sustainable development. It is an essential link for
aquaculture to move toward automation and intelligence.
However, existing fish individual data collection
methods cannot cope with the interference of light,
blur, and pose in the natural underwater environment,
which makes the captured fish individual images of poor
quality. These low-quality images can cause significant
interference with the training of recognition networks.
In order to solve the above problems, this paper
proposes an underwater fish individual recognition
method (FishFace) that combines data quality assessment
and loss weighting. First, we introduce the Gem pooing
and quality evaluation module, which is based on
EfficientNet. This module is an improved fish
recognition network that can evaluate the quality of
fish images well, and it does not need additional
labels; second, we propose a new loss function,
FishFace Loss, which will weigh the loss according to
the quality of the image so that the model focuses more
on recognizable fish images, and less on images that
are difficult to recognize. Finally, we collect a
dataset for fish individual recognition (WideFish),
which contains and annotates 5000 images of 300 fish.
The experimental results show that, compared with the
state-of-the-art individual recognition methods, Rank1
accuracy is improved by 2.60\% and 3.12\% on the public

one of 28 0.5 m 3 flow-through tanks (n = 4 tanks per

reduced to 45 fish per tank by the random removal of 15
individuals to remove any potential of density
affecting growth through the trial end. Water
temperature, oxygen saturation, pH, and salinity
throughout the trial were 11.8 {$^\circ $}C, 103.5\%,

Irrespective of the presence of KM, animal-based feeds
achieved comparable weight growth (p {$>$} 0.05) to the
control and 5\% KM plant-based groups, with KM
increasing feed intake (p {$<$} 0.05). Between day 45

specific growth rates (SGRs) decreased for all except
the 0\% KM plant-based diet. Between-group differences
(p {$<$} 0.05) were also noted for the thermal growth
coefficient. No differences were recorded in visceral
or intestinal weight, and whole-body lipid levels were
identical, proportional for all groups. Although
differences (p {$<$} 0.05) were apparent in the
concentrations of individual fillet fatty acids between
groups, a 75 g serving size of any treatment would be
sufficient to exceed daily intake recommendations for
EPA + DHA. This trial determined that benefit, in terms

KM was added to plant-based feeds. However, no such

sub-lethal effects even at low concentrations. The
persistent nature of Cd and its tendency to
bioaccumulate eventually create harmful effects on
water biota, including fish. Cd affects various aspects
of hormonal action in fish since it bioaccumulates in
the endocrine system and hinders the synthesis,
secretion, and metabolic activity of hormones, causing
severe damage along the

reproductive and developmental impairments in fish with
ecologically relevant concentrations of individual
metals can be challenging due to the complexity of
aquatic ecosystems. This review deliberated the
significant and novel trends of toxicological
difficulties and approaches, including elucidating
environmental sources' bioavailability and Cd-induced
toxic effects in freshwater fish. Both acute and
chronic exposure to Cd can cause a range of adverse
effects, such as growth inhibition, impaired
reproductive capacity, endocrine disruption, and
developmental abnormalities in freshwater fish, as
evidenced by the present review. These investigations
support the concept of Cd as a naturally available
pollutant that causes irreversible damage in fish.
These findings will help to understand the etiology of

of this study was to evaluate the biological responses

biochemical and histological analyses were conducted to
assess the biological responses of the oysters to
exposure to varying levels of solids. A difference in
valve opening detected by the Hall sensors was observed
from the second week of culture, indicating a
relationship between shell closure and higher
concentrations of suspended solids present in the
system. In terms of biochemical analysis, a significant
increase in lipid damage was observed in treatments
with medium and high levels of total suspended solids
compared with the control group. Conversely, no changes
were observed in the gill structure of the oysters
caused by the concentrations of suspended solids in the
system when compared with the control. According to the
analyses of gill activity and biochemistry, it is
suggested that C. gasar should be cultured with total
suspended solids at less than 200 mg/L. Oysters
cultivated in a biofloc system keep their shells closed
when subjected to high concentrations of total
suspended solids; concentrations of total suspended
solids below 200 mg/L do not induce oxidative stress,

non-commercial anglers and subsistence fishers in the
Central and South Pacific islands. Among the bonefish
species in the Indo-Pacific region, Albula glossodonta
are known to have one of the widest geographic ranges,
from the Red Sea to the Central Pacific, but it is
unknown how dispersive A. glossodonta are between
geographically isolated islands. Volunteer anglers
collected A. glossodonta fin clips from the main
Hawaiian Islands in the North Pacific, Anaa Atoll in
the South Pacific, and intermediate Kiritimati Island
(Line Islands) to assess the scale of dispersal and
population structure within the Pacific Ocean.
Population genomics was conducted based on 208
individuals and 7225 SNPs. Although adult A.
glossodonta exhibit strong site fidelity, genomic
results show no population differentiation between Oahu
and Maui in Hawai`i. Bonefishes exhibit significant
population structure between Anaa and Hawai`i (F ST =
0.096), with intermediate Kiritimati comprising admixed
fishes. A lengthy larval duration likely promotes
connectivity between Pacific islands. Regional
management regimes may be most appropriate for a
species with this level of dispersal.",

healthy food production, low trophic species, such as
oysters, emerge as a promising alternative. However,
regional variations in oyster production techniques,
market dynamics, and consumption patterns create
challenges for both the global and local industry's
growth. In this study, a descriptive qualitative
analysis of oyster markets across seven Atlantic
regions was carried out. The Pacific oyster
(Crassostrea gigas) was found to be farmed in most
Atlantic regions except the US but is classified as
invasive in Sweden and potentially invasive in South
Africa. Other farmed and/or harvested species include
native species (C. gasar and C. rhizophorae) in Brazil,
the American cupped oyster (C. virginica) in the US,
and the European flat oyster (Ostrea edulis) in France,
Sweden, and the US. In Irish farms, Pacific oysters are
primarily for export to European markets. The marine
aquaculture sectors of Sweden, South Africa, and
Namibia, as well as Brazil's farming for C. gasar, were
found to be underdeveloped. This study also observed a
variation in licensing, property rights, and regulatory
frameworks. Financial challenges for small businesses,
ecological implications of seed production techniques,
biosecurity risks, and public health considerations are
emphasized as critical areas for attention. This study
offers valuable insights into the selected markets and
can serve as a useful resource for policymakers,
aquaculture practitioners, and stakeholders in
optimizing global shellfish industry strategies.",

analysis revealed the presence of clusters of
macrophages expressing APG5, IL-1{\beta}, TGF-{\beta},
S100, NF-{\kappa}B, CD68, Iba-1, and Ach. Monocytes

challenges, especiallyci the unpredictability of the
marine environment and high production costs in
hatcheries. However, improving the method of
``Broodstock Conditioning In Hatcheries'' is key to
ensure permanent seed supplies by minimizing the
dependence on marine conditions and by maximizing
economic viability in hatcheries. In an effort to
overcome these barriers, broodstock were conditioned
into two different environments: (a) Natural
Environment: Natural marine conditions located in
Bah{\'\i}a Inglesa, Atacama Region, Chile. (b)
Hatchery: Laboratory conditions to achieve gonadal
maturation, spawning induction, fertilization and
larval development. The purpose of this research was to
evaluate how the type of reproductive conditioning
affects the reproductive potential and nutritional
quality of the progeny. Both methods were successful at
inducing the necessary maturity for reproduction,
obtaining viable gametes and larvae. On the other hand,
it was observed that in the natural environment, the
oocytes and D larvae reached a greater size and
nutritional value, being the most significant
differences with (p {$<$} 0.05): the size of the D
larvae reached figures of 95.8 {\pm} 3.1 {\mu}m and
91.2 {\pm} 2.7 {\mu}m in the environment and hatchery,
respectively; the lipid content in dry mass was 25.2
{\pm} 3.1 mg g {$-$1} and 13.5 {\pm} 1.9 mg g {$-$1}
for the natural environment and hatchery, respectively.
Although quality indicators in hatcheries were slightly
lower compared to the natural environment, the
possibility of conditioning A. purpuratus broodstock
independently of environmental variability highlights
the importance of further optimizing broodstock
conditioning aspects in hatcheries that would allow
more predictable and sustainable production.",

low water temperature, long-term ice cover, low levels
of nutrients, and low biodiversity. These conditions
mean that minor climatic changes may be of great
importance to Arctic freshwater organisms, including
fish, by influencing vital life history parameters such
as individual growth rates. In this study, Arctic charr
sampled from two Svalbard lakes (78--{79$^\circ $} N)
over the period 1960--2008 provided back-calculated
length-at-age information extending over six decades,
covering both warm and cold spells. The estimated
annual growth in young-of-the-year (YOY) Arctic charr
correlated positively with an increasing air
temperature in summer. This increase is likely due to
the higher water temperature during the ice-free
period, and also to some extent, due to the winter air
temperature; this is probably due to thinner ice being
formed in mild winters and the subsequent earlier ice
break-up. However, years with higher snow accumulation
correlated with slower growth rates, which may be due
to delayed ice break-up and thus a shorter summer
growing season. More than 30\% of the growth in YOY
charr could be explained specifically by air
temperature and snow accumulation in the two Arctic
charr populations. This indicated that juvenile
Svalbard Arctic charr may experience increased growth
rates in a future warmer climate, although future
increases in precipitation may contradict the positive
effects of higher temperatures to some extent. In the
longer term, a warmer climate may lead to the complete
loss of many glaciers in western Svalbard; therefore,
rivers may dry out, thus hindering migration between
salt water and fresh water for migratory fish. In the
worst-case scenario, the highly valuable and attractive
anadromous Arctic charr populations could eventually
disappear from the Svalbard lake systems.",

Feeding grass carp with the strain CYS06 for 4 weeks
significantly enhanced the resistance of the fish to A.

Flavobacterium columnare under co-culture and reduce
the amount of F. columnare adherence on the gills of
grass carp, indicating that CYS06 has good potential

In conclusion, we isolated an antagonistic probiotic
strain, CYS06, which exhibits a biological control
effect on septicemia and columnaris disease caused by
Aeromonas spp. and F. columnare in grass carp,

Multivariate analyses found that fishing depth, season,

ornamental species with sexually biased ornamental
values that favor males. Therefore, it makes sense to
breed mono-male fingerlings as ornamental fish. The
spotted scat has an XX/XY sex determination system;
therefore, the first step in producing genetically
all-male offspring should be the induction of a fertile
sex-reversed XY pseudo-female, which would then be
mated with a normal XY male to produce a YY super-male.
However, the XY pseudo-female produced by estradiol (E
2) treatment failed due to ovarian malformations. Here,
male to female sex reversal was induced in spotted scat
through a combination of E 2 and an androgen inhibitor
(trilostane, TR). Spotted scat fingerlings of
approximately 2.8--3.5 cm were fed a diet containing
both E 2 (300 {\SGMLmicro}g/g) and TR (300
{\SGMLmicro}g/g). The fish were treated for 90 days and
then fed a normal diet until they reached one year of
age, when they were sampled. Twenty-eight treated XY
individuals were identified using sex-linked markers.
According to their gonadal histological
characteristics, these treated XY fish could be divided
into three groups: males with testes (n = 21), intersex
individuals with ovaries--testes (n = 3), and fully
sex-reversed individuals with ovaries (n = 4). All
treated XX fish (n = 8) developed into normal females.
There were no obvious abnormalities in the ovaries of
the XY sex-reversed fish compared to the treated XX
fish. Serum 11-ketotestosterone (11-KT) levels were
significantly lower in XY-reversed females and treated
XX females than in XY males. Compared with XY male
fish, the expression of female (42sp50, foxl2, figla,
zar1, and zp2) and male (dmrt1, gsdf, amh and cyp11b2)
biased genes was up- and down-regulated, respectively,
in the gonads of XY-completely sex-reversed fish.
Immunohistochemical results indicate that 42Sp50 was
expressed in oocytes of XY-partially and completely
sex-reversed fish, while strong Gsdf signals were
mainly detectable in testicular somatic cells of
XY-partially sex-reversed fish and XY male fish. XY
females were successfully produced by the combined
treatment of E 2 and TR in the spotted scat. Their
fertility will be tested in the future.",

increased frequency of micronuclei, erythrocyte

sector of aquaculture. While several warm-water fish
have been reared in aquaponics, almost no data are
available for cold-water species. The determination of
nitrate toxicity thresholds in recirculating
aquaculture is crucial. Different pollutants are
typically more toxic at elevated temperatures. We
investigated the performance of Oncorhynchus mykiss
under two different nitrate levels and two
temperatures. We applied a 2 $ \times $ 2 factorial
design, where fish (9.78 {\pm} 0.51 g) were exposed to
nitrate concentrations of 40 or 110 mg/L NO 3 {$-$} and
to temperatures of 17 {$^\circ $}C or 21 {$^\circ $}C
for 20 days. This study focused on understanding the
physiological responses of rainbow trout to relatively
low nitrate levels under heat stress in order to
investigate the feasibility of integrating this species
into commercial aquaponics. The growth, condition, and
expression of genes involved in metabolism, heat shock,
antioxidant, and immune response were assessed in the
liver, together with the activities of enzymes related
to glucose and fatty acid metabolism. High nitrate
levels at 17 {$^\circ $}C affected the condition but
did not alter growth, leading to increased glycolytic
potential and, occasionally, a greater reliance on
lipid oxidation. Antioxidant defense was mainly induced
due to high nitrates and the similar expression
patterns of antioxidant genes observed under high
nitrate at both 17 {$^\circ $}C and 21 {$^\circ $}C.
Warm exposure decreased condition and growth, leading
to greatly reduced glucokinase transcription,
irrespective of the nitrate levels. Exposure to 21
{$^\circ $}C and high nitrate led to equivalent growth
and condition as well as to a milder inflammatory
response combined with metabolic readjustments
(enhancement of glycolytic and lipid oxidation
pathways) compared to the low nitrates at 21 {$^\circ
$}C. Based on the results, rearing at a temperature
close to 21 {$^\circ $}C should be avoided for
fingerling growth, while NO 3 {$-$} concentration until
110 mg/L may not have severe impacts on fingerling
health and growth at 17 {$^\circ $}C. In addition,
rainbow trout fingerlings can tolerate a 20-day
exposure at 21 {$^\circ $}C and NO 3 {$-$} up to 110
mg/L. Additional factors should always be considered,
such as specific water quality parameters, for a
comprehensive approach to assessing the feasibility of
rainbow trout aquaculture in aquaponics.",

The fish survival, weight gain (WG), and specific

significantly lower feed conversion ratios (FCRs) and
higher feed efficiency (FE) in comparison to the fed
fish monoculture system. Yet, organic filter feeders

WG, SGR, and FE with lower FCR. Environmental
parameters like temperature, oxygen, and nutrient
concentrations fluctuated but generally improved in the
IMTA system, indicating lower mesotrophic conditions.
Sediment fatty acid profiles differed between systems
and toxicity assessments, which suggested a lower
impact in IMTA and FM-IMTA systems. The sediment
microbial community displayed high similarity within

pollution in aquatic environments poses a significant
threat to the ovarian tissue and reproductive capacity
of fish, hindering the development of the aquaculture
industry. However, the combined effects of Cu and Cd on
fish gonadal development remain unclear. In this study,
the fish species Nile tilapia was stressed with rearing
water containing 300 {\mu}g/L Cu 2+ and 100 {\mu}g/L Cd
2+ for 30 days, followed by an intraperitoneal
injection of luteinizing hormone-releasing hormone
(LHRH-{\alpha}) and human chorionic gonadotropin (HCG)
at various concentrations. We investigated the ovarian
transcriptome profiles before and after injection.
Prior to injection, combined treatment with Cu and Cd
resulted in reproductive dysfunction and metal ion
imbalance in tilapia. Transcriptomic profiling revealed
differential gene annotation concentrated in the MAPK
signaling pathway and regulation of GTPase activity.
Post-injection, all concentrations of LHRH-{\alpha} and
HCG groups showed an upregulated gonadosomatic index
(G.S.I) and higher levels of vitellogenin (VTG),
gonadotropin-releasing hormone (GnRH), gonadotropin

revealed alterations in various ovarian signaling

is the scientific basis for assessing and managing
fisheries resources. The information on the dynamics of
fishing vessel voyages provided by the automatic
identification system (AIS) of vessels serves as
high-precision fishery data and provides a means of
quantifying fishing effort with high spatial and
temporal resolution in the tuna longline fishery. Based
on the AIS data of five tuna longliners operating in
the waters near the Marshall Islands from 2020 to 2021,
this study used three methods, namely the threshold
screening method, the construction of a BP neural
network and the support vector machine (SVM) to
identify the fishing and non-fishing status of the tuna
longliners, respectively. This study investigates the
status identification and fishing effort estimation of
the tuna longliner (VESSEL A) in 2021 based on the
constructed optimal model, and spatial correlation
analyses are performed between the fishing effort
estimated in hours based on AIS data and in hooks based
on fishing logbook data, by month. The results showed
(1) the recognition accuracy of the threshold screening
method is 89.9\%, the recognition accuracy of the BP
neural network classification model is 95.11\%, the
kappa coefficient is 0.51, the recognition accuracy of
the SVM classification model is 95.74\% and the kappa
coefficient is 0.52; (2) in comparison, the SVM
classification model performs better than the other two
status identification methods for tuna longliners; and
(3) the correlation coefficients between the two types
of effort of VESSEL A were greater than 0.79 on all
fishing months, indicating that there was no
significant difference in the spatial and temporal
distribution between the two types of effort. This
study suggests that the SVM model can be used to
identify the status and estimate the fishing effort of
longliners.",

constructed 80 different combinations of temporal

optimal temporal scale for the deep learning fishing

scale is {0.25$^\circ $} $ \times $ {0.25$^\circ $}.
Larger time scales lead to higher model accuracy, and
latitude has a greater impact on the model than
longitude. It further enriches and refines the criteria

28 g/L, 36 g/L, and 44 g/L, and two stocking densities,
namely, 300 and 600 shrimp/m 3, were used to analyze
the synergistic effect of high salinity and stocking
density on the growth performance, digestibility, and
energy budgets of L. vannamei. The experimental testing
period lasted 45 days. The research results showed that
a salinity level of 36 g/L was the most suitable
salinity level for shrimp growth under both high and
low stocking densities. The body weight, specific
growth rate, and relative weight gain of the shrimp in
the 36 g/L salinity group were significantly higher
than those in the other two salinity groups under both
high and low stocking densities. The high-density
farming group with 600 shrimp/m 3 exhibited a
significant inhibition of shrimp growth compared to the
low-density group under the same salinity conditions.
The activities of amylase, lipase, and protease in the
high-density-group shrimp gradually decreased with an
increase in salinity, and the three digestive enzymes
had the same overall effect of changing trends. This
indicates that under high-density farming conditions,
the increase in salinity is not conducive to the
digestive function of shrimps. At the same time, the
proportion of respiratory energy to feeding energy
gradually decreased in the high-density group and with
the increase in salinity. However, under the same
salinity conditions, the higher the stocking density,
the higher the energy consumed by respiration compared
to the low-density group. In addition, the expression
of the growth-related gene's small nuclear
ribonucleoprotein polypeptide G (SNRPG) under high
stocking density was significantly lower than that in
the low-density group at a salinity of 28 g/L, and
ribosomal protein L7 (RPL7) expression was also
significantly lower under high stocking density than
that in the low-density group at a salinity of 44 g/L.
The expression levels of molting-related genes retinoid
X receptor (RXR), ecdysone receptor (ECR), and
ecdysone-induced protein 75 (E75) were significantly
higher in the 36 g/L salinity group compared with the
other two salinity groups under high-stocking-density
treatment. The findings indicate that the synergistic
effects of salinity and stocking density have a

excessive salinity would inhibit its growth in the

freshwater aquaculture industry in China, encompassing
an expansive farming area of over 6000 km 2 nationwide.
Currently, crab farmers rely on manually monitored
feeding platforms to count the number and assess the
distribution of crabs in the pond. However, this method
is inefficient and lacks automation. To address the
problem of efficient and rapid detection of crabs via
automated systems based on machine vision in
low-brightness underwater environments, a two-step
color correction and improved dark channel prior
underwater image processing approach for crab detection
is proposed in this paper. Firstly, the parameters of
the dark channel prior are optimized with guided
filtering and quadtrees to solve the problems of
blurred underwater images and artificial lighting.
Then, the gray world assumption, the perfect reflection
assumption, and a strong channel to compensate for the
weak channel are applied to improve the pixels of red
and blue channels, correct the color of the defogged
image, optimize the visual effect of the image, and
enrich the image information. Finally, ShuffleNetV2 is
applied to optimize the target detection model to
improve the model detection speed and real-time
performance. The experimental results show that the
proposed method has a detection rate of 90.78\% and an
average confidence level of 0.75. Compared with the
improved YOLOv5s detection results of the original
image, the detection rate of the proposed method is
increased by 21.41\%, and the average confidence level
is increased by 47.06\%, which meets a good standard.
This approach could effectively build an underwater
crab distribution map and provide scientific guidance
for crab farming.",

abstract = "In recent years, there has been an increase in the
reporting of plastic pollution in the marine
environment and its effects on marine animals,
especially bony fish. However, the prevalence and
effect, particularly concerning biomarkers of oxidative
stress, in elasmobranchs remain underreported and
unknown. In this study, microplastics were observed in
two elasmobranch species from the Balearic Islands: the
small-spotted catshark (Scyliorhinus canicula) with an
average of 4.38 {\pm} 1.77 items per individual, and
the blackmouth catshark (Galeus melastomus) with an
average of 8.31 {\pm} 2.46 items per individual.
Moreover, for the first time, antioxidant and
pro-inflammatory responses were determined in the
digestive tract of individuals of both species.
Specifically, the activation of antioxidant defences,
mainly superoxide dismutase activity and glutathione
levels, was observed, while the pro-inflammatory marker
myeloperoxidase activity was also greater in
individuals with a high abundance of microplastic
items. Additionally, a significant increase in
glutathione S-transferase activity in catsharks with
high microplastic ingestion was evidenced, suggesting
that the detoxification process was activated. Overall,
the results of this study highlight that both catshark
species are ingesting microplastics, which, in turn,
are causing physiological effects at a cellular level.
Considering this, continued monitoring of these species
should include the presence of microplastics, and the
results from this study can serve as baseline data for
future research.",

humans and exhibits pathogenic behavior in several
aquaculture fish species. To date, in Brazil, there are
no reports of V. vulnificus outbreaks in farmed fish.
However, in 2019, sorubim (Pseudoplatystoma sp.) in the
grow-out phase with clinical signs and cumulative
mortality of 40\% was registered. We aimed to identify
and characterize the etiological agents of this
outbreak. Seven moribund fish were sampled for
bacteriological studies, and isolates were obtained
from the brain and kidneys. Bacterial identification
using matrix-assisted laser desorption ionization mass
spectrometry (MALDI-TOF/MS) revealed V. vulnificus. One
isolate, RP4, was used for identification via dnaJ and
16S rRNA gene sequencing and antimicrobial
susceptibility evaluation. Sorubim juveniles were
experimentally challenged with RP4 isolate via
intracelomic injection (IC, 10 7 colony-forming units
[CFU] fish {$-$1}) and immersion bath (IB, 10 6 CFU mL
{$-$1} for 30 min). Identities to V. vulnificus of dnaJ
and 16S rRNA genes by BLAST analysis were higher than
92\% and 98\%, respectively. Susceptibility to
oxytetracycline, florfenicol, and other antimicrobial
molecules was also observed. In the IC-challenged
group, the mortality rate was 100\% with V. vulnificus
recovered from fish organs (brain, liver, spleen, and
kidney). Additionally, splenic endothelium alterations
were observed in the IC group. On the contrary, the
control and IB groups did not develop any clinical
signs, mortality, or bacterial recovery after 7 days of

sustainable source of nutrients for aquafeeds, offering
an alternative to expensive and ecologically
undesirable ingredients, in the context of population
explosion and climate change. Despite this promising
outlook, its effects on fish growth and immune
responses remain to be thoroughly investigated. Our
scientific goal was to experimentally test responses to
replacements of the fish meal with a protein source
derived from black soldier fly larvae meal (BSFLM).
Possible impacts on growth, immunological response, and
the expression of selected immune-system related genes
were evaluated in Koi carp (Cyprinus carpio var. koi)
using a biofloc culture system. Three hundred fish
(20.0 {\pm} 0.2 g) were allocated into five groups: a
control group receiving a basal diet containing 0 g kg
{$-$1} BSFLM and four experimental groups in which fish
meal was replaced with 50, 100, 150, and 200 g kg
{$-$1} BSFLM for eight weeks. After 4 weeks of feeding,
there were no statistically significant differences in
specific growth rate (SGR), feed conversion ratio
(FCR), and survival rate between fish fed
BSFLM-enriched diets at 50, 100, 150 g kg {$-$1} and a
control (0 g kg {$-$1} BSFLM) diet. However, fish fed
200 g kg {$-$1} BSFLM showed significantly improved
weight gain (WG) and SGR compared to the control after
4 weeks; this difference persisted through 8 weeks (p
{$<$} 0.05). After eight weeks, there was a moderate to
weak negative linear regression shown in FCR (r =
0.470) and SR (r = 0.384), respectively, with the BSFLM
levels, but significant and highly correlated linear
relationships were observed in WG (r = 0.917) and SGR
(r = 0.912). Immunological response analysis showed
slight changes in lysozyme and peroxidase levels by
replacing fish meal with BSFLM, but these apparent
differences were not significantly related to
experimental diets. Interestingly, mRNA transcripts of
immune-related genes (TNF-{\alpha}, TGF-{\beta}, IL1,
IL10, and hsp70) were upregulated in the groups
receiving higher amounts of BSFLM, with statistically
significant differences observed in certain
comparisons. Our findings reveal that fish meal can be
effectively replaced by BSFLM, and that this not only
has a positive effect on immune-related gene expression
in Koi carp, but also on growth rate, pointing to the
future potential role of BSFLM as an alternative fish
meal protein in aquafeed formulation.",

P-glycoprotein (P-gp) is an active transmembrane
transporter that plays a pivotal role in facilitating
the movement of both endogenous and xenobiotic
substrates (moderately hydrophobic and amphipathic
compounds) across cell membranes. P-gp exhibits
substrate specificity often shared with other ABC
transporters and solute carrier proteins, thereby
ensuring the maintenance of chemical homeostasis within
cells. These transporters are integral to chemical
defense systems in fish, as they actively expel a wide
range of substrates, primarily unmodified compounds,
from cells. This transport process assists in
preventing chemical absorption (e.g., intestine),
safeguarding sensitive tissues (e.g., brain and
gonads), and effectively excreting substances (e.g.,
liver and kidney). Upregulated P-gp export activity in
aquatic animals results in the multi-xenobiotic
resistance (MXR) phenotype that plays an essential
protective role in survival in contaminated
environments. Pollutants inhibiting P-gp are termed
chemosensitizers and heighten fish sensitivity to toxic
P-gp substrates. While the known intrinsic functions of
P-gp in fish encompass steroid hormone and bile acid
processing, relatively little attention has been given
to endogenous substrates and inhibitors. Fish
P-glycoprotein regulation is orchestrated by pivotal
nuclear transcription factors, including pregnane X

several hypotheses have been proposed to explain this
variation. Two of the most prominent hypotheses
regarding the evolution of cognition link increased
social and habitat complexity with advanced cognitive
abilities. Several studies have tested predictions
derived from these two hypotheses, but these were
rarely conducted under natural conditions with wild
animals. However, this is of particular importance if
we aim to link cognitive abilities with
fitness-relevant factors to better understand the
evolution of cognition. The biggest hurdle to assessing
cognition in the wild is to find a suitable setup that
is easy to use under field conditions. Here, we set out
to evaluate an extremely simple test of cognitive
ability for use with a broad range of aquatic animals
in their natural habitat. We did so by developing a
detour test paradigm in which fish had to detour a
clear obstacle to reach a food reward. By altering the
difficulty of the task, we confirmed that this setup is
a valid test of cognitive abilities in wild groups of a
Lake Tanganyika cichlid, Neolamprologus pulcher.
Subsequently, we probed specific predictions from the
two major hypotheses regarding cognitive evolution
using the most difficult test configuration.
Specifically, we tested the variation in cognitive
abilities among groups of different sizes occupying
habitats of varying complexity. We find mixed support
for both hypotheses, but we hope that our work inspires

opilio) began in Newfoundland and Labrador, Canada, in
1967. Today, the fishery consists of 2188 active
fishing licenses and has grown into the province's most
economically valuable fishery. Snow crabs are captured
using conical traps consisting of a mild carbon steel
frame, hard plastic entry funnel and a jacket of
polyethylene netting. The frames of these traps corrode
over time, which is expedited by being deployed in
marine environments and stored on land near the ocean
when not in use. As a result, there is interest within
the community to increase the longevity of crab traps.
One solution is to galvanize the steel frames prior to
installing the funnel and netting. However, before
harvesters transition to galvanized traps, two
questions must be answered. Will the use of galvanized
steel negatively impact catch rates? Will the life
cycle of a crab trap be extended sufficiently to
justify the additional cost of galvanizing? This study
employed a generalized linear mixed model to evaluate
the catch of legal-sized male crabs (CPUE) during the
commercial fishery as a function of three trap frame
treatments (old traditional, new traditional and new
galvanized). We also assessed the economic viability of
galvanizing trap frames by evaluating the life cycle
cost (LCC) of traditional and galvanized traps to the
harvester. The LCC was calculated over a range of
inflation (0--6\%) and discount (3--20\%) rates. Our
results found no significant difference in CPUE between
new traps (traditional vs. galvanized) and concluded
that except during instances of very high discount
rates (12.9--19.9\%), it is economically favourable to

aquaculture encounters many difficulties when the
species pauses its growth but resumes its later after
the disrupting phenomenon (environmental or
physiological) has been overcome. Seasonal or
oscillatory growth has been addressed by modifying
existing models, such as von Bertalanffy and Gompertz,
to include an oscillatory component in this study. The
novelty of this study lies in the fractal approach used
to analyze growth using multiple logistic functions.
Three commercially farmed marine species were studied,
including shellfish, crustacea, and finfish. The
oscillatory version of the von Bertalanffy model as
well as double and triple logistic functions were used
for analysis. The best model was selected using the
information theory, Specifically the Akaike criterion
(AIC) and the Bayesian criterion (BIC). Normal and
log-normal distributions of error were assumed. The
triple logistic model with log-normal distribution in
the error structure was found to be the best model to
describe the growth pattern of the three commercially
farmed species as it obtained the lowest AIC. Overall,
this study concludes that the fractal approach is the
most effective way to describe growth in farmed
species, including shellfish, crustacean, and
finfish.",

of Rana (Aquarana) catesbeiana. R. catesbeiana
tadpoles, in their short larval period, possess a high
survival rate and also a highly competitive ability in
the amphibious stage. In actual seed production, the
economic traits of larval period and metamorphosis rate
are used as quantifiable indicators of quality for
individuals and populations, respectively. However,
studies of these economic traits in larval cultivation

constructed 40 full-sib families of R. catesbeiana and
measured the weight and metamorphosis rate of tadpoles
at different developmental stages. Subsequently, we
calculated the phenotypic and genetic association
between weight and metamorphosis rate in tadpoles and
assessed the heritability of these two traits. The
heritabilities of weight at three developmental stages
were all higher than 0.40 and decreased with
advancement of the developmental stage; the
heritability of the metamorphosis rate was 0.18 {\pm}
0.20, a moderate level. Correlation analysis of weight
and metamorphosis rate at each developmental stage in
each tadpole family showed that weight at stages 25-I,
25-II, and 25-III was significantly correlated at the
phenotypic level but non-significantly at the genetic

associated with stage 25-III weight (0.38, p {$<$}

small-scale fisheries along the eastern Mediterranean
coast. This species depredates on fishing gears,

Additionally, observer surveys carried out on board
small-scale fishing vessels in Crete showed that
depredation probability was significantly influenced by
fishing depth, sea surface temperature, gear type

and crucial to many animals' survival. Fish embryos use
a variety of chemical cues to initiate hatching to
avoid potential predators, yet the function of chemical
cues released from the predatory consumption of
heterospecific prey is largely unknown. Zebra cichlids
(Metriaclima estherae) are ferocious predators that can
feed on medaka (Oryzias latipes), though it is
impossible for this to occur in their natural habitat.
Zebrafish (Danio rerio) embryos have been employed as
experimental subjects due to their sensitivity to a
variety of chemical signals. In this study, zebrafish
embryos were subjected to three types of chemical
signals: predator cues (PCs, released from cichlids),
heterospecific cues (HCs, released from medaka), and
heterospecific dietary cues (HDCs, released from
cichlids that have ingested medaka). As a result, the
hatching times of zebrafish embryos were accelerated by
6.8\% and 12.6\% by PCs and HDCs, respectively. PCs and
HDCs cause significantly reduced morphology in
zebrafish embryos, including regarding total length,
eye length, dorsal fin length, trunk height, caudal fin
height, and body cavity, and increase yolk sac height.
The PCs and HDCs diminished the larvae's motion at 120
and 144 h post fertilization (hpf), which could be
attributed to non-developmental embryogenesis. Overall,
the impacts of HDCs on embryonic hatching,

positive allometric growth, which is consistent with
similar patterns observed in this species from the Syr
Darya River basin. The two analyzed condition factors
showed mean values within the normal range, indicating
good feeding and environmental conditions. However,
significant disparities between minimum and maximum
values of these factors indicated varied growth
conditions which may be influenced by anthropogenic
factors. Age estimation using opercular bones showed
variations in the total length among fish of the same
age, and a clear age distribution pattern across
different sites. Younger fish predominantly inhabited
the shallower, warmer, and lower sections of the river,
which is impacted by agricultural water diversion,
while older specimens were found in areas with higher

provides valuable insights into the life history traits
of S. eurystomus, underlining the need for sustainable

significant pathogen that causes the crooked head
disease in black spotted frogs. This disease has
plagued numerous frog farms in China and has resulted
in substantial losses to the frog farming industry.
Nonetheless, the exact mechanism that causes the
disease in frogs remains unknown. In this study,
transcriptomic and microbiomic analyses were conducted
to analyze frog samples infected with E. miricola to
reveal the infection mechanism of the pathogen. Liver
transcriptomic analysis indicated that the livers of
infected frogs had 1469 differentially expressed genes
when compared with an uninfected group. These DEGs are
mainly involved in immunity and metabolism, including
neutrophil extracellular trap formation, the NOD-like
receptor signaling pathway, leukocyte transendothelial
migration, chemokine signaling pathway, Fc gamma
R-mediated phagocytosis, and ``metabolism''-related
pathways such as the pentose phosphate pathway, carbon
metabolism, glycerophospholipid metabolism, and
glycerolipid metabolism. Similarly, 4737 DEGs were
found in the kidney of infected frogs. These DEGs are
mainly involved in immunity, including neutrophil
extracellular trap formation, the NOD-like receptor
signaling pathway, B cell receptor signaling pathway,
C-type lectin receptor signaling pathway, complement
and coagulation cascade, and Toll-like receptor
signaling pathway. Ten immune-associated DEGs were
screened in liver and kidney DEGs, respectively. And it
was hypothesized that E. miricola infection could
influence the host immune response. Microbiome analysis
results showed that some opportunistic pathogens such
as Citrobacter, Shigella, and Providencia were
significantly elevated (p {$<$} 0.05) in infected
frogs. Additionally, functional prediction confirmed
that most of the microbiota in infected frogs were
linked to metabolism-related KEGG pathways. In this
study, the screened genes linked to immunity showed an
association with the gut microbiome. The majority of
these genes were found to be linked with the abundance
of opportunistic pathogens. The results showed that E.
miricola infection led to the downregulation of immune
and metabolic-related genes, which led to the
inhibition of immune function and metabolic disorder,
and then increased the abundance of opportunistic
pathogens in the gut microbiota. The findings of this
study offer a preliminary foundation for comprehending
the pathogenic processes of E. miricola infection in

group due to limitations in combining information from
biogeography, morphology, and genetic data. This study
addresses the taxonomic puzzle arising from the recent
identification of Osteobrama tikarpadaensis in the
Mahanadi and Godavari Rivers, casting doubt on the
actual distribution and systematics of both O.
tikarpadaensis and Osteobrama vigorsii. The research
reveals distinctions among specimens resembling O.
vigorsii from the Krishna and Godavari riverine
systems. Notably, specimens identified as O. vigorsii
from the Indian Museum exhibit two pairs of barbels,
while those from the Godavari River in this study are
identified as O. tikarpadaensis. Inter-species genetic
divergence and maximum likelihood phylogeny provide
clear delineation between O. vigorsii and O.
tikarpadaensis. The study suggests that O. vigorsii may
be limited to the Krishna River system in southern
India, while O. tikarpadaensis could potentially extend
from the Mahanadi River in central India to the
Godavari River in southern India. Proposed revision to
morphological features for both species, accompanied by
revised taxonomic keys, aim to facilitate accurate
differentiation among Osteobrama congeners. The data
generated by this research provide a resource for

Artemia nauplii to produce each postlarvae (~1200
Artemia nauplii PL {$-$1}). The maximum mean M.

Polyculture, i.e. cultivating multiple fish species in
a single system, is being increasingly adopted for its
resource efficiency and economic benefits. This
practice for Asian fish for food and ornamental
purposes is gaining traction in Europe despite their
invasive potential. Rising temperatures due to climate
change offer an opportunity for thermophilic Asian
carps (Hypophthalmichthys molitrix and Aristichthys
nobilis). Using GIS modeling (Maxent), we identified
the possible settlement of Asian carp in Northern
Europe amidst climate change. We analyzed carp global
distribution centers, assessed the potential carp
spread in Europe, and evaluated their potential
suitability for polyculture systems. By 2050, H.
molitrix may extend its range to 58--{62$^\circ $} N
latitude, with a potential 1.7-fold habitat increase,
while A. nobilis, which are more heat-tolerant, may
move north to 52--{58$^\circ $} N latitude, with a
1.3-fold potential increase. Despite the slight
ecological differences in their native habitats, niche
modeling indicates that these carp can occupy similar
niches in Europe (proven statistically). The
eventuality of using Asian species for polyculture in
Europe presents both opportunities and challenges in
the face of a changing climate as long as invasion
risks are prevented. Envisaging such polyculture, yet

the crabs collected from TD showed a higher abundance

can play an important role for an organism's metabolic
rate, growth, and health. Previous studies have shown
that juvenile brown trout (Salmo trutta) subjected to
elevated temperatures during the embryonic stage
respond phenotypically with a reduced metabolic rate.
The aim of this study was to explore if embryonic
temperature affects the mitochondria content of young
brown trout and as such explains the previously found
differences in metabolic rates. Here, we optimize a
quantitative PCR (qPCR) method for the mitochondria
cytochrome c oxidase subunit I gene, and then use the
method as a proxy for mitochondrial DNA content. We
hypothesize that young trout subjected to elevated
temperatures during the embryonic stage respond
phenotypically with a reduced mitochondrial DNA
content. To test this hypothesis, we subjected brown
trout to either control ambient (4.4 {\pm} 1.5 {$^\circ
$}C) or elevated temperatures (7.1 {\pm} 0.6 {$^\circ
$}C) during embryogenesis. Subsequently, we extracted
DNA from liver and white muscle tissue of juvenile
brown trout from the two different incubation
temperature treatments and successively optimized qPCR
for mitochondrial DNA. We found that the amount of
mitochondria DNA in liver tissue was 18 times higher
than in white muscle tissue, but there was no
significant difference in mitochondria content in liver
or muscle tissue between brown trout exposed to
elevated and ambient control temperatures during
embryogenesis. We conclude that reduced metabolic rate
is not likely associated with mitochondria DNA content.
We also suggest that qPCR is a simple and
cost-effective method to quantify mitochondria DNA in
frozen and partly degraded tissue from different
treatment groups and a useful proxy for identification
of differences in mitochondria number.",

species of farmed and consumer crustaceans were
selected, including crayfish (Procambarus clarkii),
freshwater prawns (Macrobrachium rosenbergii), pacific
white shrimp (Litopenaeus vannamei), black tiger shrimp
(Penaeus monodon), kuruma prawns ( Penaeus japonicus),
river prawns (Macrobranchium nipponense), and Chinese
shrimp (Penaeus chinensis). Their morphometric
parameters, nutritional composition, textural
properties, and physical and chemical indexes were
comparatively analyzed. The results showed that the
meat content (MC, about 14.78\%) of crayfish was
significantly lower than that of the other six species.
By contrast, pacific white shrimp had the highest MC,
although the MCs of black tiger shrimp, kuruma prawns,
and Chinese shrimp are greater than 40\%. All seven
crustacean species were high in protein and low in fat,
while pacific white shrimp had the highest crude
protein, crude lipid, and crude ash content compared to
the other crustaceans. The content of threonine (Thr)
was the highest in crayfish. The content of methionine
(Met) and lysine (Lys) was the highest in freshwater
prawns. The content of isoleucine (Ile), leucine (Leu),
and non--essential amino acid (NEAA) was the highest in
pacific white shrimp. C18:2n-6 (linoleic acid, LA) was
the highest in freshwater prawns and pacific white
shrimp; C18:3n-3 (linolenic acid, LNA), C20:4n-6
(arachidonic acid, AA), unsaturated fatty acids (UFA),

highest in crayfish; and polyunsaturated fatty acids
(PUFA) was the highest in freshwater prawns, but the
content was not significantly different from crayfish,
pacific white shrimp, black tiger shrimp, and Chinese
shrimp. Pacific white shrimp had the highest values for
hardness, cohesiveness, gumminess, and chewiness. The
redness values of crayfish, black tiger shrimp, and
Chinese shrimp were significantly higher than those of
the other three species except kuruma prawns. Compared
to other crustaceans, river prawns had the highest drip

shrimp had the lowest cooking loss rates. The research
shows that the tail muscle of the seven species of
crustaceans is rich in protein, essential amino acids,
unsaturated fatty acids and low in fat, representing a
high-quality protein. Among these crustaceans, the main
essential amino acids and essential fatty acids in the
tail muscle of pacific white shrimp, freshwater prawns,

diseased fish. In addition, abundant granulomas were
observed in the spleen and head kidney of the diseased
fish. To define the potential pathogens from A.
rivulatus, bacteria were isolated from the visceral
tissue of diseased fish with conventional methods. An
artificial infection experiment was carried out to
prove the pathogenicity of the isolated bacteria. The
strains HG-2021-1 and HG-2021-3 were isolated from
diseased fish and identified as being responsible for
the disease. They were identified as Streptococcus
iniae based on physiological and biochemical tests,
lctO gene detection, and 16S rRNA gene sequence
analysis. According to the result of multilocus
sequence typing (MLST), HG-2021-1 and HG-2021-3 belong
to different genotypes of S. iniae. Furthermore, they
were found to contain the virulence genes pgmA, scpI,
cpsD, and pdi, and the median lethal dose (LD 50) for
A. rivulatus was 1.8 $ \times $ 10 6 Colony-Forming
Units (CFU)/mL and 6.6 $ \times $ 10 6 CFU/mL,
respectively. To our knowledge, this is the first
report of fish coinfected by two genotypes of S.
iniae.",

elucidated the natural food intake and its contribution
to tambaqui (Colossoma macropomum) growth in fertilized

stomach contents analyses. Additionally, it described
the impact of fertilization management on natural food
availability, fish performance, and production costs.
Tambaqui juveniles (93.8 {\pm} 15.0 g) were stocked
(0.55 fish/m 2) in fertilized (Fert) and unfertilized
(NoFert) ponds (600 m 2) for a culture period of 10
months in quadruplicate. A lower food conversion ratio
was observed in Fert ponds. The main natural food items
ingested by tambaqui were insects, vegetables, and
cladocerans. Plankton contributed 39.4\% and 10.7\% of
muscle formation in Fert and NoFert ponds,
respectively. Pond fertilization (2.45 g of nitrogen
and 0.80 g of phosphorus per square meter every two
weeks) did not significantly affect fish growth,
survival, or productivity but had a slightly influence
on water quality parameters. However, fertilization
increased the zooplankton density (through
phytoplankton) in the water, thereby increasing
autochthonous food availability for tambaqui
consumption. This species demonstrates the ability to
alternate between natural food sources and commercial
feed without compromising its development.
Consequently, tambaqui exhibits suitability for farming
within restorative and integrated aquaculture systems
as well as intensive systems reliant on commercial
feed.",

when the last specimens were caught in the nets. The
estimation of the growth, mortality parameters, and
exploitation rate was done in FiSAT (FAO-ICLARM Stock
Assessment Tools). The von Bertalanffy growth equation
was estimated at L {\infty} = 36.75 cm, the growth
coefficient was k = 0.68 year {$-$1}, and the
theoretical initial age was t 0 = {$-$0}.67 year
{$-$1}. The total mortality rate (Z) estimated was 2.76
year {$-$1}, with a natural mortality rate (M) and
fishing mortality rate (F) of 0.89 year {$-$1} and 1.87
year {$-$1}, respectively. The Z/k ratio was found to
be 4.11 and the exploitation rate (E) was estimated at
0.68 year {$-$1}, indicating the overexploitation of
Alosa immaculata stocks. In conclusion, this study
provides valuable insights into the population dynamics
of Pontic shad in the Danube River, Romania. The
assessments of the growth parameters, mortality rates,
and exploitation rates highlight a level of
overexploitation of Alosa immaculata stocks. These
findings underscore the importance of applying
effective fishery management strategies to ensure the
sustainability and conservation of this valuable fish
species in the Danube River ecosystem.",

of concentrated cottonseed protein (CPC) as a
substitute for fishmeal (FM) in juvenile hybrid culter
(Erythroculter ilishaeformis {[female-sign]} $ \times $
~ Ancherythroculter nigrocauda {[male-sign]}). A total
of 360 fish with an initial body weight of 10.0 {\pm}
0.5 g were randomly allocated into 12 indoor culture
tanks, with each tank containing 30 fish. Four diets
were formulated in which fish meal (FM) was replaced by
CPC at different inclusion levels: 0\% (T0), 15\%
(T15), 30\% (T30), and 45\% (T45). The corresponding
amounts of CPC included were 0, 61, 122, and 182 g/kg,
respectively. At the end of the 10-week feeding trial,
the findings revealed an inverse correlation between
the proportion of CPC replacing FM and both final body
weight (FBW) and weight growth rate (WG) in hybrid
culter. Specifically, the T30 and T45 groups exhibited
significantly lower FBW and WG compared to the T0 group
(p {$<$} 0.05). No significant differences in crude
protein and ash contents were observed among all groups
(p {$>$} 0.05). However, the crude lipid content was
highest in hybrid culter fed the T45 diet and lowest in
the T0 group (p {$<$} 0.05). There were no significant
differences in muscle amino acid composition among all
treatment groups (p {$>$} 0.05). The contents of total
protein (TP) and albumin (ALB) declined slightly as the
proportion of FM substituted by CPC increased, yet this
decline did not reach statistical significance (p {$>$}
0.05). Serum alanine aminotransferase (ALT) activity
elevated with increasing dietary CPC, and the T45 group
exhibited significantly higher ALT activity compared to
the T0 group (p {$<$} 0.05). The hepatic activities of
superoxide dismutase (SOD) and catalase (CAT) were
significantly lower in the T45 group than in the T0 and
T15 groups (p {$<$} 0.05). Furthermore, there was a
decrease in intestinal villi length with an increasing
replacement ratio of FM by CPC, and the villi length in
the T45 group exhibited a significant reduction when
compared to that in the T0 group (p {$<$} 0.05). It is
concluded that replacing 15\% FM with CPC does not
exert obviously detrimental effects on growth
performance, serum biochemical indices, intestinal
morphology, muscle amino acid profile, or antioxidant
performance of juvenile hybrid culter.",

Yaquina Bay, Oregon, a well-studied estuary, has
undergone intense development, as well as deep-draft
dredging during the latter half of the 20th century,
resulting in the alteration of ~45\% of the lower
estuary's natural shoreline. In 1967, the United States
Environmental Protection Agency (USEPA) conducted a
21-month survey of Yaquina Bay to characterize the
demersal fishes and epibenthic crustaceans that occupy
the bay. From 2003 to 2005, we conducted a 25-month
survey to replicate that work and provide a comparative
snapshot of the demersal fish and epibenthic crustacean
community in the bay. A comparison of the trawl survey
datasets reveals a 91\% decline in total catch per unit
effort (CPUE) between surveys, as well as a decline in
multiple measures of biodiversity. Furthermore, the
fishes and crustaceans of Yaquina Bay have experienced
a shift in species dominance from demersal fishes in
the late 1960s to epibenthic crustaceans in the 2000s,
marked most notably by a nine-fold increase in the
Dungeness crab CPUE. While this work does not establish
a causal relationship between changes in the demersal
communities of this West Coast estuary and human or
natural events, it does document substantial changes in
both the diversity and total abundance of animals in
that community over a three-plus decade period of
development and environmental variability. Hence, this
forms a second baseline for continued long-term

in the growth and development of vertebrates. Blotched
snakehead (Channa maculata), an economically
significant fish, exhibits obvious sexual dimorphism
and achieves sexual maturity in one year. However, the
role of IGFs in C. maculata remains unknown. Three IGF
genes were identified in C. maculata, designated as
CmIGF1-1, CmIGF1-2, and CmIGF2. The cDNA sequences of
these genes are 1184, 655, and 695 bp, encoding
putative proteins of 168, 131, and 215 amino acids,
respectively, and all three proteins contain a
conserved IGF domain. Quantitative real-time PCR (qPCR)
revealed the predominant expression of CmIGFs in the
liver of adult fish, with higher expression levels
observed in males. Notably, CmIGF1-1, CmIGF1-2, and
CmIGF2 displayed analogous expression profiles in the
liver across various developmental stages, peaking at
365 days after hatching (dah). Subsequently, 600
individuals at 75 dah, at an early developmental stage,
were randomly divided equally into six groups and
reared in aerated 2 m $ \times $ 2 m $ \times $ 2 m
cement ponds at 26.0 {\pm} 1.0 {$^\circ $}C. Following
a one-week acclimatization period, fish without
observed abnormalities were intraperitoneally injected
with either 17{\alpha}-ethynylestradiol (EE 2) or
17{\alpha}-methyltestosterone (MT) at a dose of 10
{\mu}g/g body weight. Three groups underwent short-term
hormone treatment, and the remaining three groups
underwent long-term hormone treatment, which included
five injections at two-week intervals over ten weeks.
The analysis of CmIGFs expression levels in the liver
under different hormone treatments revealed that EE 2
suppressed the expression of CmIGF1-1 and CmIGF1-2
while promoting CmIGF2 expression. In females, MT
up-regulated the expression of CmIGF1-1 and CmIGF2 in a
time-dependent manner, but consistently inhibited
CmIGF2 expression. In males, MT promoted the expression
of CmIGFs in a time-dependent manner, reaching peak
levels for CmIGF1-1, CmIGF1-2, and CmIGF2 after 8, 10,
and 2 weeks of injection, respectively. Additionally,
CmIGF1 and CmIGF2 might exhibit a complementary
relationship, with a compensatory increase in CmIGF2
expression in response to low CmIGF1 concentration.
These findings highlight the potential key role of IGFs
upon growth and their regulation by sex steroid
hormones in C. maculata, providing a crucial foundation
for future research aimed at elucidating the molecular
mechanisms underlying the growth dimorphism between
female and male blotched snakeheads.",

abstract = "Snow crab replaced groundfish fisheries as the primary
focus of the Newfoundland and Labrador (NL) fishing
industry in the mid-1990s. Over the past three decades,
management philosophies in this male-only fishery have
shifted from promoting industry expansion to promoting
industry rationalization to implementing Precautionary
Approach (PA) management. Until the mid-2010s, there
were regionalized management strategies characterized
by higher exploitation rates in northern than southern
sub-stock units along the NL marine shelves. However,
in the late 2010s, exploitation rates were permitted to
elevate to high levels across the entire stock range in
association with a large resource decline, and evidence
of biological harm through fishing emerged in
chronically depleted areas. In 2019, when stock and
fishery productivity were near historical lows, a
multi-indicator PA system was informally introduced
into the management of the resource. This event
coincided with anticipated improvements in stock and
fishery performance. This paper examines the extent to
which the multi-indicator PA management system, focused
on the promotion of both biological protection and
maximization of fishing efficiency, may have
contributed to recent improvements in stock and fishery
status. A suite of indicators from areas implementing
PA guidance into management in 2019 prior to the formal
adoption of the PA system in 2023 suggest the system
has been highly beneficial in promoting rapid recovery
and improving stock and fishery performance metrics to
levels matching or exceeding historical levels under
similar conditions. We discuss the capacity of the
system to better safeguard biological aspects of
resource and fisheries productivity moving forward
under a scenario of an expectant resource decline.",

Findings reveal that the visibility of pot lights at

day) and time elapsed post-deployment. Additional
factors influencing the vision of the pots include
water column quality and benthic boundary layer
turbidity. This study is the first to model the visual

study, we identified the full-length cDNA of Calm
(termed MaCalm) in blunt snout bream M. amblycephala,
and analyzed MaCalm expression patterns in response to
cadmium and Aeromonas hydrophila challenges. MaCalm was
1603 bp long, including a 5{\prime}-terminal

3{\prime}-terminal UTR of 1056 bp and an open reading
frame (ORF) of 450 bp encoding a polypeptide of 149
amino acids with a calculated molecular weight (MW) of

Usually, MaCalm contains four conservative EF hand
motifs. The phylogenetic tree analysis indicated that
the nucleotide sequence of MaCalm specifically
clustered with Ctenopharyngodon idella with high
identity (98.33\%). Tissue distribution analysis
demonstrated that the ubiquitous expression of MaCalm
mRNA was found in all tested tissues, with the highest
expression in the brain and the lowest expression in
muscle. MaCalm showed significant upregulation at 14 d

cadmium in the liver; HSP70 transcripts in the liver
significantly upregulated at 14 d post exposure to
different concentrations of cadmium. Moreover, in
response to the A. hydrophila challenge in vivo, MaCalm
transcripts in the liver first increased and then
decreased, but MaCalm transcripts in the kidney
declined gradually with prolonged infection. After the
A. hydrophila challenge, the expression level of HSP70

the most commercially important crustacean species in
China. The aim of this study was to characterize the
toxic effects of butachlor (an herbicide of the
acetanilide class) on juvenile E. sinensis crabs. The
lethal effects and the acute toxicity of butachlor on
juvenile E. sinensis specimens were assessed through a
semi-static in vitro experiment. We determined the
activities of superoxide dismutase (SOD) and catalase
(CAT) as well as the levels of glutathione (GSH) and
malondialdehyde (MDA) in the gills and the
hepatopancreas of the juvenile crabs, at different time
points over a 14-day short-term exposure to butachlor.
Moreover, we measured the residual levels of butachlor
in three different tissues (gills, hepatopancreas, and
muscles) of the juvenile crabs over a longer period.
Our findings revealed that butachlor is highly toxic
for juvenile E. sinensis crabs. In fact, the median
lethal concentration (LC 50) values of butachlor at 24,
48, 72, and 96 h were found to be 4.22, 1.84, 0.34, and
0.14 mg/L, respectively, while the safe concentration
was 0.014 mg/L. The antioxidant defense ability of the
juvenile E. sinensis crabs against butachlor was
induced after exposure to the herbicide at a
concentration of 0.01 mg/L. After 14 days of exposure
to butachlor at 0.04 and 0.16 mg/L, both SOD and CAT
were found to be significantly inhibited (p {$<$}
0.05), the GSH levels were found to be significantly
decreased (p {$<$} 0.05) and the MDA levels were
identified as significantly increased (p {$<$} 0.05).
Moreover, after 14 days of exposure to butachlor at
0.16 mg/L, the activities of SOD and CAT as well as the
content of GSH in the hepatopancreas were found to be
significantly decreased (p {$<$} 0.05). Our results
revealed that a high concentration of butachlor was
capable of inducing oxidative stress and damage in
juvenile E. sinensis crabs. The maximal residual value
of butachlor was obtained in the gills, with a content
of 4.56 {\mu}g/kg. Butachlor was not detected after 24
days in the aforementioned three tissues of the

aquaculture model of P. vannamei and water spinach (
Ipomoea aquatica) was used to investigate the effect of
a water spinach floating raft on water quality,
antioxidants, non-specific immune response, growth
performance, and microbial diversity. The experimental
design of this study consisted of two groups with three
replicates for each, i.e., control group: aquatic
monoculture (AM) system with only P. vannamei;
treatment group: P. vannamei - I. aquatica raft
aquaponics (AP) system with a 50\% cover ratio with a
water spinach floating raft. The experiment lasted for
seven weeks. The results show that the concentrations
of total phosphorus (TP), total nitrogen (TN), nitrate
nitrogen (NO 3 {$-$} -N), ammonia nitrogen (NH 4 + -N),
nitrite nitrogen (NO 2 {$-$} -N), and active phosphorus
(AP) in the AM group were higher than those in the AP
group at different sampling times. The water quality
index of the AP group was better than that of the AM
group, indicating that water spinach can remove the
nutrients from aquaculture water bodies. The average
daily gain and survival rate of shrimp in the AP group
were higher than those in the AM group. The total
antioxidant capacity (T-AOC), catalase (CAT),
superoxide dismutase (SOD), malondialdehyde (MDA), and
acid phosphatase (ACP) in the AP group were better than
those in the AM group. The Shannon--Wiener and Simpson
indices of the gut, water, and sediment of the AP
system were significantly higher than those in the AM
system, which implied a higher abundance of
microorganisms in the AP system. These results
demonstrate that the application of a water spinach
floating raft in aquaponics can not only improve the
water quality, but also improve the growth performance,
antioxidant system, and non-specific immune responses
of Pacific white shrimp, while increasing the abundance
of microorganisms in the aquaculture system and
improving the ecological benefits in terms of the
expenditure.",

long-term feeding. Haematococcus pluvialis (HP), yeast
Phaffia rhodozyma (PR), and synthetic astaxanthin (SA)
were added to the basic feed (no astaxanthin, NA) to
prepare the isonitrogenous and isolipidic experimental
diets; the actual astaxanthin content values in the
diets were 31.25, 32.96, and 31.50 mg/kg, respectively.
Eighteen hundred O. mykiss, averaging 670 {\pm} 20 g,

with the experimental diet for four months. Dietary
supplementation of P. rhodozyma and synthetic
astaxanthin had no significant effects on the growth

the PR and SA was statistically lower than that in the
NA and HP; the redness and astaxanthin content of
fillet in the HP, PR, and SA groups were statistically
higher than those in the NA. The total antioxidant

acetyl-CoA-carboxylase (ACC) gene in response to the
cold stress of M. rosenbergii, we investigated the
effects of RNA interference (RNAi) with the ACC gene on
the expression of fatty acid metabolism-related genes

The results showed that different siRNA sequences and
different injection concentrations had different

siRNA-III with an injection concentration of 2.0
{\mu}g/g (siRNA/prawn body weight) had the best
interference effect. With the optimal siRNA and the
optimal concentration under cold stress, the
expressions of three fatty acid metabolism-related
genes, FabD, echA, and ACOT, were generally
significantly down-regulated. Compared to negative
(scrambled-siRNA) and blank (PBS) control groups, the
expression of FabD in the interference group was
extremely significantly down-regulated at 12 h in the
hepatopancreas and at 18 h in the muscles and gills;
EchA was highly significantly down-regulated at 6 and
12 h in the muscles and gills; and ACOT was extremely
significantly down-regulated and kept declining in the
gills. Within 6--18 h after injection under cold
stress, the mortality rate of the siRNA interference
group (75\%) was much lower than that of the negative
(95\%) or blank control group (97.5\%), and all prawns
died after 24 h. In conclusion, RNA interference with
the ACC gene inhibited the expression of some fatty

environmental stressors like temperature fluctuations
and exposure to heavy metals. Chromium (Cr 6+) is a
known environmental pollutant that poses a threat to
aquatic life. Various environmental factors, such as
water temperature, have been found to affect the
toxicity of dissolved chemicals in aquatic ecosystems.
We investigated the toxicity of combinations of
different concentrations of hexavalent chromium (Cr 6+
) with high temperatures in fish. Hematological indices
demonstrated changes in white blood cells (WBCs),
hematocrit (HCT), red blood cells (RBCs), and
hemoglobin (Hb) levels during the exposure. The
qualitative and semi-quantitative analyses of different
tissues confirmed that higher concentrations of Cr 6+
caused more significant damage than lower
concentrations, with evident alterations observed in
circulatory and regressive aspects. Furthermore, brain
acetylcholinesterase levels decreased in both single
heavy metal exposure and combined exposure at a high
temperature. The activity of antioxidant oxidase and
immunological parameters increased in all treatment
groups compared with the control group following
long-term exposure. A significant and increased effect
of Cr 6+ in the high-temperature groups was observed on
the evaluated biomarkers, suggesting a possible
synergistic effect between Cr 6+ and increased
temperature. The integrated biomarker response (IBR)
reported the highest level of stress at 10 mg/L Cr 6+
combined with high temperature. The IBR analysis
revealed that the highest activity of response enzymes,
such as acid phosphatase (ACP), superoxide dismutase
(SOD), and glutathione S-transferases (GST), was
observed in the liver, whereas the gills displayed
alkaline phosphatase (ALP), GST, and SOD activity, and
the kidneys demonstrated SOD, ACP, and aspartate

histopathology, antioxidant enzymes, and metabolism-

the efficiency indicators in terms of feed, water,
energy, and infrastructure materials used, were

four IMTA trials in three aquaculture facilities in
Ireland, Brazil, and South Africa. Salmon, white
shrimp, tilapia, abalone, and sea urchins were studied

variability of zebrafish lines. We compared
morphological variability (yolk--chorion ratio, body
mass, embryo mass, total length, condition factor, and
specific growth rate) in wild-type AB and NHGRI-1
zebrafish lines as a function of their responses to
altered temperature and oxygen availability during the
first 7 days post-fertilization. Overall, both lines
showed similar developmental trajectories for
yolk--chorion ratio, embryo mass, and total length.
Additionally, condition factor and specific growth rate
showed similar responses within each line, regardless
of temperature and hypoxia. Importantly, the
coefficient of variation for each variable was
significantly lower in NHGRI-1 than AB larvae for 151
of 187 assessed morphological endpoints. Thus, the
low-heterozygosity NHGRI-1 zebrafish line can be useful
for decreasing inter-individual variation in
morphological responses to environmental stressors,
thereby aiding in the interpretation of results and
enhancing experimental reproducibility.",

to this study, no comprehensive life history
information existed in the literature for queen

comprehensive documentation of age, growth, size/age at
sexual maturity, reproductive seasonality, and
reproductive output for a Balistes species in the
Caribbean. From 2013 to 2023, we collected 2190 fish
samples from fisheries-dependent and -independent
sources from the waters of Puerto Rico and the U.S.
Virgin Islands. Fish ranged from 67 to 477 mm fork
length (FL). We documented that queen triggerfish is
sexually dimorphic with males attaining larger mean
sizes-at-age compared to females and the species is
characterized by a moderately young age at median
sexual maturity (A 50 = 3.3 y). The maximum age for our
U.S. Caribbean samples was 23 y based on increment
counts from otoliths. Spawning season encompassed the
months of December to August in the region, and female
spawning frequency ranged from an estimated 2 to 84
times per year; female spawning frequency increased
with increasing size and age of fish. We documented
that commercial fishers in the U.S. Caribbean mainly
target ``plate-size'' individuals, defined in our study
as 235--405 mm FL, which appears to act as a
self-imposed slot size range limit and results in the
fishery not removing individuals in the smallest and
largest size groups at high rates. The percentage of
immature fish from fisheries-dependent sources was
close to 0 (0.8\%). Commercial fishing for queen
triggerfish in the region currently appears to be

two BMP genes, BMP2 and BMP4, were cloned and
characterized in the red crucian carp (Carassius

showing ubiquitous expression across all studied

fish to NP stress resulted in a downregulation of BMP2,
BMP4, and other genes associated with the BMP-Smad

allows farmers to take swift action to protect fish

an enhanced high-precision detection algorithm based on
YOLOv9, named DDEYOLOv9, to facilitate the detection
and counting of abnormal fish behavior in industrial
aquaculture environments. To address the lack of
publicly available datasets on abnormal behavior in
fish, we created the ``Abnormal Behavior Dataset of
Takifugu rubripes '', which includes five categories of
fish behaviors. The detection algorithm was further
enhanced in several key aspects. Firstly, the DRNELAN4
feature extraction module was introduced to replace the
original RepNCSPELAN4 module. This change improves the
model's detection accuracy for high-density and
occluded fish in complex water environments while
reducing the computational cost. Secondly, the proposed
DCNv4-Dyhead detection head enhances the model's
multi-scale feature learning capability, effectively
recognizes various abnormal fish behaviors, and
improves the computational speed. Lastly, to address
the issue of sample imbalance in the abnormal fish
behavior dataset, we propose EMA-SlideLoss, which
enhances the model's focus on hard samples, thereby
improving the model's robustness. The experimental
results demonstrate that the DDEYOLOv9 model achieves
high Precision , Recall , and mean~Average~Precision (
mAP) on the ``Abnormal Behavior Dataset of Takifugu
rubripes '', with values of 91.7\%, 90.4\%, and 94.1\%,
respectively. Compared to the YOLOv9 model, these
metrics are improved by 5.4\%, 5.5\%, and 5.4\%,
respectively. The model also achieves a running speed
of 119 frames per second (FPS), which is 45 FPS faster
than YOLOv9. Experimental results show that the
DDEYOLOv9 algorithm can accurately and efficiently
identify and quantify abnormal fish behaviors in

Sebastes schlegelii were subjected to varying durations

NovaSeq 6000 platform. The transcriptome data were
analyzed to identify DEGs through pairwise comparisons
across a control group and two experimental groups

The comparative DEG analysis revealed a significant

40 s exposure group (BS) compared to the control (BC),
6742 DEGs in the 2 min 30 s exposure group (BD)
compared to the control (BC), and 2653 DEGs when
comparing the BD to the BS group. Notably, Gene
Ontology (GO) analysis showed an enrichment of DEGs
associated with peptidase activity and extracellular
regions, suggesting a role in the organism's stress
response. Kyoto Encyclopedia of Genes and Genomes
(KEGG) pathway analysis pointed to the involvement of
metabolic pathways, which are crucial for energy
management under stress. The upregulation of protein
digestion and absorption pathways may indicate a
physiological adaptation to nutrient scarcity during
stress. Additionally, the identification of antibiotic
biosynthesis pathways implies a potential role in
combating stress-induced infections or damage. The
identified DEGs and enriched pathways provide insights
into the complex anti-stress response mechanisms in

peptidase activity and extracellular region-related
genes may reflect the initiation of tissue repair and
immune response following air exposure. The connection
between protein digestion and absorption pathways and

metabolic readjustment to prioritize energy-efficient
processes and nutrient assimilation during stress. The

sampling with gillnets, trammel nets, and longlines,
one individual of F. petimba was captured off the coast
of Katapola Bay. Morphological examination confirmed
its identity, with measurements on meristic
characteristics obtained and the stomach content
analysed. This finding represents a significant
addition to the documented distribution of F. petimba
in the Mediterranean Sea, particularly in the Aegean
Sea, underscoring the importance of ongoing research in
uncovering new occurrences and expanding our
understanding of marine biodiversity and ecosystem
changes. Further investigation into the ecological
preferences and population dynamics of F. petimba in
the Aegean Sea is crucial for informed conservation and

to adapt to varying iron levels. Iron
limitation-induced genes play crucial roles in energy
metabolism, transport, and catabolism pathways.
Moreover, 27 ortholog genes were associated with iron
transport and homeostasis, with 7 of them participating

extending into the pituitary gland. Cellular and
nuclear areas were greater in D compared to ND in the

crossings such as bridges and culverts can lead to
zones of high-velocity water flow that impede fish
passage. Such obstacles are likely to harm native fish
populations by impacting migrations critical to their
life history strategies, causing habitat fragmentation
and extirpation, thereby limiting population growth and
distribution. Due to the high rates of human population
growth and development occurring in Texas, this is an
issue of particular concern for fish designated as
species of greatest conservation need (SGCN). This
project focused on four SGCN fishes native to the
Edwards Plateau Ecoregion, namely the Guadalupe Bass,
Guadalupe Roundnose Minnow, Guadalupe Darter, and
Plateau Shiner, at both adult (all species) and
juvenile (Guadalupe Bass only) life stages. Our primary
aim was to aid in the design of future culverts
associated with stream crossings (or the modification
of existing culverts) so that the water velocities
through these structures do not exceed the swimming
capacities of our target SGCN fishes. To this end, we
assessed their maximum sustained swimming speeds (U
crit) under a typical range of Edwards Plateau stream
temperatures (15, 22.5, and 30 {$^\circ $}C) to be used
in site-specific calculations of the maximum allowable
culvert water velocities (Vf). A secondary objective
was to collect physiological endpoints of relevance to
the overall swimming performance including the maximum
burst swimming speeds (U max), metabolic rate
measurements (i.e., standard metabolic rate (SMR),
maximum metabolic rate (MMR), and aerobic scope (AS)),
cost of transport (COT), and optimal swimming speed (U
opt). Temperature-related effects were observed that
can be used to inform site-specific culvert designs. In

hundred and eighty Bulatmai barbel (Luciobarbus capito:

(C), Cd and Cd + Se-enriched L. plantarum groups
(S1L1-Cd) and fed for 28 days. The analysis methods
included histopathology, test kits, transcriptomics and
real-time quantitative PCR. The addition of
selenium-enriched L. plantarum significantly attenuated
cadmium-induced pathological changes such as glomerular
atrophy, detachment of renal tubular epithelial cells,
mild swelling, and interstitial inflammatory cell
infiltration. Cd stress can lead to significant
decreases in RBC, HCT, WBC, LZM, C3, and IgM levels,
and the addition of Se-enriched L. plantarum can
significantly reverse the changes in these indicators.
Transcriptomic analysis revealed 488 DEGs in the Cd
groups, 301 of which were upregulated and 187 of which
were downregulated. There were 1474 DEGs in the S1L1-Cd
group, of which 720 were upregulated and 754 were
downregulated. In addition, GO enrichment analysis
revealed that the biological regulation of the most
differentially expressed genes involved metal ion
binding, ATP binding and nucleotide inclusion. KEGG
enrichment analysis revealed six of the most enriched
pathways: oxidative phosphorylation, Huntington
disease, retrograde endocannabinoid signalling, natural
killer cell-mediated cyto-toxicity, the IL-17
signalling pathway, and leukocyte transient migration.
Moreover, we selected 12 DEGs for qRT-PCR, which showed
that the qRT-PCR results were consistent with our

abstract = "Groupers are valuable economic fish in the southern
sea area of China, but the threat of disease is
becoming more and more serious. Vibrio harveyi, V.
parahaemolyticus, and Singapore grouper iridovirus
(SGIV) are three important pathogens that cause disease
in groupers, and infection with either a single one or
a mix of these pathogens poses a serious threat to the
healthy development of grouper culture. To enhance the
rapid diagnosis and screening in the early stages, it
is necessary to develop rapid detection methods of
these pathogens. To simultaneously and rapidly detect
the three pathogens, in this study, we utilized the
TolC of V. harveyi, DNAJ of V. parahaemolyticus, and
RAD2 of SGIV as the target genes and established a
triple visual loop-mediated isothermal amplification
(LAMP) method. This LAMP method showed a detection time
as fast as 30 min and a high sensitivity of 100
fg/{\mu}L. Moreover, this method exhibited strong
specificity and no cross-reaction with seven types of
Vibrio and Staphylococcus aureus, as well as five
common viruses in aquatic animals. Then, the LAMP
products were enzymically cut, and three characteristic
strips were used to identify the pathogen species. The
results of the clinical trials demonstrated that the
method could accurately and specifically detect V.
harveyi, V. parahaemolyticus, and SGIV in grouper
tissues. In summary, this study successfully
established a triple visual LAMP rapid detection method
for V. harveyi, V. parahaemolyticus, and SGIV. The
method offers several advantages including simple
equipment, easy operation, rapid reaction, high
specificity, high sensitivity, and visual results. It
is suitable for the early and rapid diagnosis of
groupers infected with V. harveyi, V. parahaemolyticus,
and SGIV, thereby providing useful technical support
for further application in the large-scale disease

by a multitude of intrinsic (within-individual) and
extrinsic (environmental) factors that underpin
individual fitness and population dynamics. Interannual
variability in river hydrology regarding the intensity
and duration of floods and droughts can induce
interannual variations in the biotic and abiotic
variables that regulate fish growth. However, the
understanding of how interannual variability in river
hydrology affects fish growth remains limited for most
species and ecosystems. We evaluated how inter-annual
hydrological variations within the Amazon River basin
influence the growth of the catfish Pseudoplaystoma
fasciatum. Our research questions were as follows: Do
floods lead to the faster growth of P. fasciatum and
droughts lead to the slower growth? And do floods and
droughts affect all age classes in the same manner? We
sampled 364 specimens of P. fasciatum from five sites
in the Amazon basin, estimated their growth rates, and
related the growth rates to indices of the intensity of
floods and droughts. We fitted linear mixed-effects
models to test the relationship between growth
increments and hydrological indices (with F and D
quantifying the intensities of floods and droughts,
respectively), age as fixed effects, and basins and
Fish ID as random effects. We found an inverse
relationship between the increment width in the fish
hard parts and hydrological indices. That is, intense
floods and droughts negatively affected the growth
rates. We also found that the growth of P. fasciatum
was no different in years with intense and mild floods
across age classes 1--5, although was different for age
class 6. However, the growth of P. fasciatum was faster
in years of mild droughts for all age classes. Our
results showing that the growth of P. fasciatum was
slower in years of intense droughts are supported by
those of previous studies in the Amazon basin and
elsewhere. However, our results showing for the first
time that the growth of P. fasciatum is slower in years
of intense flooding is the opposite of patterns found
in other studies. These results thus suggest that the
growth of P. fasciatum is maximized within an optimum
range of hydrological conditions, where neither floods
nor droughts are intense.",

and Obdnd were specifically expressed in gonads. In the
testis, Obdazl and Obdnd RNAs have a similar expression
pattern: their transcripts were abundant in
spermatogonia, gradually decreased, and eventually
disappeared during spermatogenesis. Early oocytes in
the ovary exhibited strong expression of Obdazl and
Obdnd RNAs and reduced remarkably after peak expression
at III oocytes. Surprisingly, Obdazl RNA was
dynamically found in perinuclear spots that finally
aggregated into the Balbiani body (Bb) in the early
oocytes. Moreover, Obdazl 3{\prime} UTR enabled the
reporter gene to be expressed stably in medaka PGCs,
suggesting that dazl was identified as the germ cell
marker in O. bidens, which may provide perspectives for
further studies on the development of PGCs in the
future.",

abstract = "Coastal fisheries are vital for food supply,
employment, and social stability. However, overfishing
is a common problem, often attributed to open access.
Territorial Use Rights in Fisheries (TURFs) have gained
popularity as a tool to improve the sustainability of
coastal fisheries, but research on TURFs in China is
limited. This paper examines the island reef fishery
lease policy implemented in Shengsi County, Zhejiang
Province, within the Ma'an Islands National Marine
Special Reserve. The policy leases the use of island
reefs to a collective, aiming to address overfishing
and resource degradation by establishing fishing area
boundaries and limiting the number of users and usage
time. Technically, it is an application of TURFs, and
it represents a shift from traditional fishing licenses
to collective compliance. This experience has disrupted
the existing top--down fishery governance structure and
signifies a transition to a rights-based fishery
management system in China. Through a comprehensive
investigation and analysis of the policy's
implementation, this research identifies the factors
contributing to its flaws. These include the inadequate
provision of national and local government policies,
insufficient support for policy implementation from
fishery management authorities, and the limited
involvement of fishermen's organizations. To enhance
coastal fishery management, we propose that the Chinese
government should build upon existing foundations by
clarifying fishing rights through central and local
laws and policies. Additionally, there is a need to
strengthen data monitoring of coastal fisheries,
conduct multidisciplinary research to improve the
allocation mechanism of fishing rights, adopt diverse
fishery management approaches to enhance supervision
capabilities, establish a collaborative governance
mechanism, and foster coordination and cooperation
between grassroots fishermen's organizations and
government departments.",

removers in Norwegian salmon farming and are mostly

systematic documentation on the mortality causes of
lumpfish in hatcheries. In the current study, data from
12 selected fish groups from four hatcheries in Norway
were collected to understand the challenges and
opportunities related to the categorization of
mortality causes of lumpfish in hatcheries. This study
indicated that a high proportion of lumpfish mortality
was categorized by the hatcheries as unspecified. When
specified, mortality was primarily assessed as due to
fin damage. Our analyses showed that mortality
categorized as fin damage correlated with the detection
of infectious agents in dead fish, suggesting that
mortality was due to infections rather than fin damage.
It was not possible to conclude whether infection with
pathogens present in the environment caused fin damage
or if injuries from aggression were a gateway for
pathogens. Furthermore, due to the lack of information
regarding production conditions, it was not possible to
assess risk factors causing eventual aggression or the
presence of pathogens. This study revealed that
mortality causality --- the chain of events leading to
death --- is mainly unclear in lumpfish hatcheries
because (1) mortality categorization does not focus on
underlying causes and (2) there is little documentation
of production conditions, making it very difficult to
relate mortality rates to external factors. The present
findings highlight that there are gaps in the
registrations made by hatcheries and that there is an
urgent need to implement standardized monitoring
protocols for lumpfish hatcheries. This will help
identify the causes of mortality and, therefore, allow
for the implementation of proper measures that will

differences in the gonads were described. Nevertheless,
sex differences in gene expression in non-gonadal
tissues ostensibly affected by the sex-specific
hormonal balance, e.g., the brain, are unknown. To
assess such differences, we used bulk RNA-seq to
assemble and compare polyA+ transcriptomes between
whole brains of four adult male and five adult female
gourami, in addition to other tissues (three dorsal fin
and five ovary samples) from the same female group.
While all nine brain transcriptomes clustered together
relative to the other tissues, they showed separation
according to sex. A total of 3568 genes were
differentially expressed between male and female
brains; of these, 1962 and 1606 showed lower and higher
expression in males, respectively. Male brains showed
stronger down-regulation of specific genes, which
included hormone receptors, e.g., pituitary adenylate
cyclase-activating polypeptide receptor (pacap-r1).
Among the genes with lower expression in male brains,
multiple pathways essential to brain function were
over-represented, including GABA, acetylcholine and
glutamate receptor signaling, calcium and potassium
transmembrane transport, and neurogenesis. In contrast,
genes with higher expression in male brains showed no
significant over-representation of brain-specific
functions. To measure the mRNA levels of specific
hormone receptors known from prior studies to regulate
reproductive function and behavior in gourami and to
validate RNA-seq results for these specific genes, we
performed RT-qPCR for five receptors, pacap-r1,
gonadotropin-releasing hormone 2 receptor (gnrh2r),

insulin-like growth factor 1 receptor (igf1r), and

significant, three-fold down-regulation, while
gp{\alpha}r1/kiss1 showed a significant two-fold
down-regulation in male vs. female gourami brains. Our
results are novel in describing the suppression of
brain function-related gene expression in male, as
compared to female, gourami brains. Further research is

fisheries in West Africa. Many observers have blamed
climate change and the system of open access for the
decline. Open-access fishing encourages too many people
to take up fishing, and the result is overfishing of
the stocks. According to such critics, this is a
classic example of Hardin's tragedy of the commons,
whereby a continuous increase in the number of users of
a natural resource eventually leads to the collapse of
the resource. The present study, which analysed
stakeholders' perceptions about their open-access
fishing in Siera Leone's marine fisheries, conducted 32
key informant interviews. Our research found that while
they perceived that open-access fishing impacted fish
stocks, most Sierra Leone's marine capture fishers did
not see open access as a cause of fish decline;
instead, they blamed the lack of enforced regulations
on the methods and extent of fishing. Accordingly,
these fishers favoured the continuation of open access
--- not least because it helps to alleviate hunger and
is a readily available source of protein in Sierra
Leone's coastal communities --- but accompanied by
strict regulations on both the type of fishing gear
used and the quantity, size, and species of fish
caught. In other words, they preferred regulated open
access to unregulated open access. The central
government's resolve to regulate its fishery will
determine whether it will transition from unregulated
open access to regulated open access or other forms of
OA. This study recommends detailed research into how to

fishery resource surveys between 2020 and 2021. The
results showed that 93 fish species were identified,
belonging to 11 orders, 20 families, and 61 genera,
which was an increase of 4.5\% from before the fishing
ban. Of these, 52 Cyprinidae species were identified,
comprising the highest proportion (55.91\%). Four
invasive alien species (hybrid sturgeon, Cirrhina
mrigala, Piaractus brachypomus, and Mugil cephalus)
were identified, and the number of alien species in
Poyang Lake was higher than before the fishing ban.
Carnivorous and mid-lower-level fish showed a
significant increase, accounting for 47.31\% and
38.71\% of the total species, respectively. Compared
with the Yangtze River before the fishing ban, the body
length and body weight of the main economic fish in
Poyang Lake increased by 6.10--61.26\% and by
15.14--291.57\%, respectively. In terms of age
structure, the proportion of major economically
important fish aged 1 or 2 years decreased
significantly, while the proportion of older fish
increased substantially. There was little difference in
the diversity of fish communities at different stations
in Poyang Lake. In terms of biodiversity, the
Shannon--Wiener index ranged from 2.158 to 2.909, with
Poyang having the highest value and Nanjishan the
lowest. Margalef's index ranged from 4.265 to 6.459,
with Lushan having the highest value and Nanjishan the
lowest. Pielou's index ranged from 0.617 to 0.822, with
Duchang having the highest value and Nanjishan the
lowest. Hence, the Yangtze river fishing ban has played
an important and positive role in the restoration of
fishery resources in Poyang Lake. However, long-term
tracking and monitoring are needed to provide
information to comprehensively evaluate the ecological
impact of the Poyang Lake fishing ban.",

primarily during summer and late autumn. The latter
included a transition from the bottom to the surface
layer at dusk, continuous and high activity close to
the surface during the night, and then descent back to

in the Mediterranean Sea is far from thorough. The
present work attempts to assess the preying patterns

sternoptychid (Argyropelecus hemigymnus,~Maurolicus

Greece), sampled during pelagic trawl surveys in 2018

caught during daytime, a pattern which sternoptychids
did not follow. Estimated trophic indices revealed high
dietary diversity (Shannon's H ' index) for most
investigated species, but a narrow trophic niche
breadth (Levins' normalized B n index). Copepods and
various marine crustaceans were dominant in all diets,
classifying them under the zooplanktivorous trophic

stomachs and N. elongatus exhibited consumption of
fish. Diet overlap was significant among most studied

Ctenopharyngodon idellus) ranks among the most
extensively cultivated freshwater aquaculture species
in China. However, little is known about the function
of SRB1 in C. idellus. In this research study, a SRB1
gene was identified in C.~idellus, named CiSRB1. The
full-length cDNA of CiSRB1 is 2486 bp long, with an
open reading frame (ORF) of 2486 bp encoding a 497
amino acid (aa) protein containing a conserved CD36
domain. The identified genomic DNA length of CiSRB1 is
20,042 bp, including 12 exons and 11 introns. The
predictive analysis of protein interactions revealed
that Ci SRB1 could interact with the outer capsid
proteins of typical GCRV strains. The tissue
distribution of CiSRB1 exhibited age-dependent
characteristics. CiSRB1 displayed the highest
expression in the intestines and moderate levels in
muscle, spleen, liver, and brain of one-year-old grass
carp while maintaining relatively low levels in
three-year-old grass carp. Following grass carp
reovirus (GCRV) infection, notable upregulation of
CiSRB1 transcripts was observed in major immune tissues
(gills, intestines, spleen, and liver). Furthermore,
significant differences were found between one-year-old
and three-year-old grass carp, with lower CiSRB1
expression levels being detected in the older group.
Additionally, a distinct response to GCRV infection was
observed in one-year-old and three-year-old grass carp.
It was found that one-year-old individuals had a
mortality rate of up to 84\% 6 days post-infection
(dpi), whereas all three-year-old counterparts survived
after GCRV infection. The analysis of GCRV copy numbers
across tissues revealed substantially higher levels in
one-year-old grass carp compared with their older
counterparts, confirming the existence of age-dependent
susceptibility to GCRV infection in grass carp.
Combined with these results, it was speculated that the
decline in cell-surface CiSRB1 expression with age may
impede reovirus binding to host cells, potentially
explaining why older grass carp demonstrated enhanced
resistance to GCRV infection. This observation
accentuates the importance of CiSRB1 in the context of
GCRV infection and provides insights into age-dependent
susceptibility to reovirus.",

the possibility of enhancing the quality of earthen

wild environment. This study investigated how rewilding
time affects the physical properties, nutritional
composition, and volatile profile of grass carp muscle.
The results showed that compared to the 0M group, the
crude protein content in grass carp muscle did not
change significantly (p {$>$} 0.05) as the rewilding
time increased to 6 months. Meanwhile, the significant
increase in hardness and springiness (p {$<$} 0.05)
indicated that the textural characteristics of muscle,
which were key sensory and physical indices of muscle
quality, were improved. Although the 6M group showed a
58.93\% reduction in crude fat content compared to the
0M group, it retained the highest docosahexaenoic acid
(DHA) content. Sensory evaluation demonstrated that as
the rewilding time increased, the fishy and grassy
odors of the rewilding grass carp diminished.
Furthermore, cluster heatmaps and partial least squares
discriminant analysis (PLS-DA) revealed that cultured
grass carp and rewilding grass carp at three time
points exhibited differences in various indicators. The
variable importance in projection (VIP) showed that
volatile flavor compounds (acetone, propionaldehyde-D,
1-penten-3-ol) and hardness were key factors in
distinguishing between them. Therefore, extending the
rewilding time can potentially enhance the
acceptability of cultured grass carp by improving the

comprehensive project (BIOACID) addressing the
physiological resilience of Polar cod, Boreogadus

aimed to unravel underlying molecular mechanisms of the
observed physiological responses. Methods: Fish were
acclimated long-term to three CO 2 concentrations
comprising control conditions (390 ppm) and two
projected climate scenarios (780 ppm and 1170 ppm).
Each CO 2 treatment was combined with four
temperatures: 0, 3, 6, and 8 {$^\circ $}C. Here, we
focused on the hepatic transcriptomic profiles from
these previously physiologically characterized fish.
Results: Generally, we did not detect signs of a
classical stress response. Consistent with functional
observations, warming induced much stronger molecular
responses compared to elevated P CO 2, but an
interaction between both factors existed to some
extent. Gene ontology analysis revealed a strong
response in lipid, amino acid, and protein metabolism.
With increasing temperature, we observed a shift away
from lipid metabolism, while carbohydrate metabolic
pathways remained stable. Conclusions: Although we
found Polar cod to be quite resilient to ocean
acidification, temperature will remain a critical
parameter for this valuable Arctic keystone species,
and the question remains as to whether the observed
acclimation strategies can be implemented in its
natural habitat, especially when food supply is

season. Our dataset presented here spans from 2018 to
2023 and suggests that mature adults of S. squatina and
S. oculata still occur in Turkish waters, in Fethiye
Bay and {\c{C}}anakkale, respectively. Due to elevated
chances of fishers encountering Critically Endangered
angel sharks in T{\"u}rkiye, we suggest that fishers
are trained in handling and safe-release methods, to
ensure reduced incidents of capture-induced
parturition, and improved post-release survival. This
study demonstrates that bottom set nets set by
small-scale fishers pose less risk to mortality for
angel sharks as they are almost always encountered
alive after a usual 12 h soak time, suggesting that
bottom trawling in critical habitats should be better
regulated (or phased out) to help improve national
angel shark conservation initiatives.",

effects of salmon gonadotropin releasing hormone analog
(S-GnRH-A) and human chorionic gonadotropin (HCG) on
the serum levels of gonadotropins (GtHs) and sex
steroid hormones in Manchurian trout during sexual
maturity. Females in the treatment group were injected
with 20 {\SGMLmicro}g/kg S-GnRH-A and 400 IU/kg HCG,
whilst males were injected with half the amount. Blood
samples were collected at 0, 5, 10, and 20 days post
injection (dpi). The results showed an increase in
female follicle-stimulating hormone (FSH) levels in the
treatment group at 5 dpi, and from 5 dpi onwards, a
difference was observed between the groups, with higher
FSH levels in the treatment group compared to the
control group. In males, FSH levels showed group
differences at only 5 dpi (p {$<$} 0.05) and were
higher in the treatment group. In females, luteinizing
hormone (LH) peaked at 10 dpi in the treatment group,
and there were differences between the two groups at 10
dpi and 20 dpi. In males, LH was significantly higher
in the treatment group than in the control group at 5
dpi and 10 dpi (p {$<$} 0.05). In females, estradiol
(E2) was significantly higher in the treatment group
than in the control group at 5 dpi and 10 dpi (p {$<$}
0.05), whereas in males, the difference between the two
groups was only observed at 5 dpi (p {$<$} 0.05). The
female testosterone (T) level in the treatment group
was significantly higher than that of the control group
at 5 dpi and 10 dpi (p {$<$} 0.05), while T levels were
significantly higher in the male treatment group than
in the control group at 5 dpi (p {$<$} 0.05). The level
of 17{\alpha}--hydroxyprogesterone (17{\alpha}-OHP) in
the females of the treatment group was significantly
higher than that of the control group at 5 dpi and 10
dpi (p {$<$} 0.05), and 17{\alpha}-OHP levels were
significantly higher in the male treatment group than
in the control group at 10 and 20 dpi (p {$<$} 0.05).
The fish were successfully spawned after S-GnRH-A and
HCG injections, and brood amount, fertilization rate,
and hatching rate were significantly increased (p {$<$}
0.05). This study provides a framework for a better
understanding of the mechanisms of exogenous

embryos were exposed to these drugs from 5 hpf (hours
post-fertilisation) to 6 dpf (days post-fertilisation).
Dopamine levels were determined by ELISA, and the
expression of Fos proteins, Creb, its activated form
p-Creb and tyrosine hydroxylase (Th) were examined by
Western blot. Both drugs decreased Th levels at 72 hpf
and 6 dpf and modified the expression of Fos family
members, pCreb and Creb in a time-dependent manner.
Morphine and cocaine exposure differentially modified
dopamine levels in 72 hpf and 6 dpf zebrafish embryos.
Our results indicate that drugs of abuse modify the
expression of several proteins and molecules related to
the activation of the reward pathway.",

of the digital economy and marine fishery development
from 2011 to 2022, we firstly adopted the entropy

Secondly, we constructed a two-way fixed effect model

the mediating role of marine green science and
technology innovation, and further explored the
regional heterogeneity of the digital economy on the
marine fishery economy quality. Several findings
emerge. The digital economy and the marine fishery
economy quality level was relatively low and showed a
fluctuating increase. The development of the digital
economy can significantly improve the economy quality
of marine fishing, and the conclusion was still valid
after considering a series of robustness tests. The
digital economy can drive the development quality of
the marine fishery economy through marine green

androgen (T) on the gonadotropin-releasing hormone
(GnRH) and gonadotropin (GtH) within the
brain--pituitary--gonad (BPG) axis in eels with
undeveloped ovaries were investigated through in vivo
studies. However, the regulatory role of the BPG axis
only became apparent during ovary development in the

was explored through in vitro exposure. The mRNA
expression levels of GnRH (mGnRH), GtH (fshb and lhb ),
and steroid biosynthesis enzymes (cyp11a1, hsd3b,
cyp17a1, and cyp17a2) in the diencephalon, pituitary,
and ovary, respectively, were determined. The results
showed that the expression level of mGnRH in the
diencephalon was significantly downregulated by 0.1
IU/mL hCG but upregulated by both 1 nM E2 and higher
concentrations of T, suggesting a direct positive
feedback regulation of E2 on mGnRH. In the pituitary,
the expression levels of fshb and lhb were upregulated
by E2, while fshb was suppressed by T. In the ovaries,
the expression of cyp11a1 and hsd3b was upregulated by
1 nM E2, whereas T exposure resulted in an opposite
effect. Cyp17a1 mRNA levels did not differ
significantly with E2 treatment but were upregulated by
1 nM T. These findings suggest that low concentrations
of E2 exhibited positive feedback regulation on all
three levels (diencephalon, pituitary, and ovary) of

many pivotal roles, and contributing to the growth or
health performance of animal hosts. Thus, many studies
are currently looking for potential beneficial bacteria
``probiotics'' from diverse environments, including
wild species. The present study aimed to investigate
the diversity and potential metabolic functions of
bacterial communities in the gastrointestinal tract of
wild spiny lobsters. The gastrointestinal (GI) tracts
of two wild lobster species (Panulirus ornatus and
Panulirus homarus) were dissected aseptically and
analyzed through high-throughput sequencing, followed
by PICRUSt analysis. The results exposed that the most
dominant phyla inhabiting both lobster species at the
post-puerulus and juvenile stages were Proteobacteria,
Firmicutes, Bacteriodota, Patescibacteria, and
Verrucomicrobiota, while at the genus level, the GI
tracts were mostly dominated by Photobacterium,
Candidatus Bacillopora, Vibrio, and Catenococcus at the
post-peurulus stage, and Vibrio, Catenococcus,
Acanthopleuribacter, Acinetobacter, Pseudoalteromonas,
Grimontia, and Photobacterium at the juvenile stage.
Further metagenomic prediction analysis discovers many
potential probiont properties indicated by the
detection of marker genes corresponding to many
important metabolic activities, such as antimicrobial
compounds (streptomycin, vancomycin, carbapenem,
tetracycline, novobiocin, penicillin, cephalosporin,
ansamycines, butirosin, and neomycin), antioxidants
(e.g., flavonoids and carotenoids), and several
important digestive enzymes (e.g., lipase, protease,
and amylase). These results suggest that GI tracts of
wild spiny lobsters are potential sources to discover
novel probionts for aquaculture purposes. Further
studies, such as the isolation of the natural
product-producing bacteria, or cloning of the
beneficial compound-identified genes, are highly
recommended to develop novel probiotic strains for
aquaculture purposes.",
