The purpose of this research was to determine the most selective mesh size of gillnet fishing gear for Pampus argenteus in coastal waters of Pangandaran Regency, West Java. Research on the selectivity of gillnet fishing gear was carried out in the coastal waters of Pangandaran, West Java Province, from August 2018 to January 2019. The method used in this research is experimental fishing, namely operating gillnet fishing gear directly in the fishing area with fishermen. The primary data collected was the measurement of the catch (fish weight, number, fork length, how the fish was caught, circumference (girth opercullum, maximum body girth). Meanwhile, the secondary data collected were supporting data from the Pangandaran District Fisheries and Marine Service, and literature study. In determining the sampling, the method used is the purposive sampling method. The operation of gillnets using 4.5 inches obtained a higher proportion of main catch (75%) than gillnets with a mesh size of 5 inches (44%). Gillnet with a mesh size of 4.5 inches, the silver pomfret caught was distributed between 17-22 cm in size with the highest mode in the 19 cm fork length. Unlike the gillnet fishing gear with a mesh size of 5 inches, the silver pomfret caught was distributed in the fork length range of 17-25 cm with the highest mode in the length class 19 cm fork length. mesh size 4.5 inches has a hanging ratio value of 0.51. Meanwhile, the 5 inch mesh size has a hanging ratio value of 0.54. Based on the length distribution, gillnets with a mesh size of 5 inches were more dominant in catching silver pomfret in a larger size class interval than gillnets with a mesh size of 4,5 inches. Based on the L50 value, both selective gillnets caught more fish at 50% second chance. The selectivity curve shows that gillnet fishing gear with a mesh size of 5 inches has more selective results than gillnets with a mesh size of 4.5 inches.

- Abstract
Insulin-like growth factor 1 (Igf1) is known to promote ovarian maturation by interacting with other hormones. However, the limited research on the role of Igf1 in the energy metabolism supply of gonads has hindered further exploration. To explore the role of Igf1 in gonadal development of silver pomfret, we analyzed the expression levels and the localization of igf1 mRNA and protein during testicular and ovarian development of silver pomfret. The results of the study showed upregulation of Igf1 in the critical period of vitellogenesis and sperm meiosis, which was found to be mainly expressed in the somatic cells of the gonads. Upon adding E2 and Igf1 to cultured gonadal tissues, the expression of energy-related genes was significantly increased, along with the E2-enhanced effect of Igf1 in the testis. Importantly, stimulation of both ovaries and testes with E2 and Igf1 led to a remarkable increase in the expression of vitellogenesis and meiosis-related genes. Therefore, we conclude that Igf1 promotes vitellogenesis and sperm meiosis by regulating gonadal energy production. Moreover, the expression of Igf1 in gonads is significantly regulated by E2. These findings provide new insights for the research of Igf1 in fish breeding, thus allowing the regulation of energy metabolism between growth and reproduction for successful reproductive outcomes., (© Crown copyright 2023.)

Abstract: The growth hormone (GH) is a pluripotent hormone produced by the pituitary in vertebrates. It plays important roles in the growth, development, and metabolism of vertebrates.We cloned GH cDNA sequence of Pampus argenteus (GenBank: KT257176). Multi‐sequence analysis revealed P. argenteus GH cDNA contained four conservative cysteine residues positions (Cys69, Cys177, Cys194, and Cys202) and shared more than 51.5% identity with homologues from other reported bony fish GHs, except that of Lepisosteus osseus. We used semi‐quantitative RT‐PCR and quantitative real‐time PCR to detect GH expression in 10 tissues and GH expression levels in the pituitary at six different growth stages, and also detected GH content in serum at different growth stages. qPCR showed that GH mRNA was detected in the liver, muscle, kidney, intestine, pituitary, olfactory bulb, stomach, heart, gill, and ovary. The highest level of P. argenteus GH mRNA was observed in the pituitary (P < 0.01, n = 3). At different growth stages, P. argenteus GH expression first increased, decreased, and increased again. GH gene expression levels and the variations of serum GH levels of P. argenteus were consistent with the growth rate and associated with the sexual maturity. In addition, in situ hybridization was used to locate the GH expression in pituitary. In situ hybridization showed that the GH‐positive cells were round, oval, or irregular and often gathered into groups or presented branches along the nerve fibers. [ABSTRACT FROM AUTHOR]

The Sparidentex hasta and Pampus argenteus species of fish consumed in the south of Iran are abundant in a particular season, so they should be frozen for consumption throughout the year. That is why this research was carried out to investigate the effects of freezing on some of the physicochemical properties of the fillets of the fishes. Such parameters were determined as fat (by the chloroform-methanol method), the amount of TBA (thiobarbituric acid) in fish muscle (by Pearson's method), pH (with a pH meter), and FFA (Free fatty acids) - by the titration method, in the presence of phenolphthalein. They were determined basing on the percentage of oleic acid. The peroxide value, according to AOAC (Association of Official Analytical Chemists), was tested in fresh samples at time zero and after different periods of freezing. The results showed that the TBA content in fish fillet for Pampus argenteus and Sparidentex hasta was 0.65 and 0.53, respectively. The highest percentage of fat was found for Pampus argenteus after 95 days (24.22%), and for Sparidentex hasta after 35 days (25.19%). The highest free fatty acids contents (0.9% and 0.97%) was found for Sparidentex hasta and Pampus argenteus after 95 days. It can be concluded that the TBA and FFA contents and pH of both fish species increased during storage in a freezer. The peroxide value in Pampus argenteus was reduced, but in Sparidentex hasta showed no significant differentce. The best time of storage of Pampus argenteus and Sparidentex hasta at -18°C was 35 days of freezing, but the nutritional value of the fillets and the fatty acids reduced greatly.

Matrix metalloproteinase (MMP)-9 belongs to the zinc-dependent endopeptidase family, which is associated with important inflammatory processes and plays an important role in cell metabolism, embryonic development, and wound repair. The present study was performed using Pampus argenteus individuals fed with different feeds. The full-length cDNA of the MMP-9 gene was 2783 bp and encoded 681 amino acids. The amino acid sequence analysis of Pampus argenteus MMP-9 showed that it contained a highly conserved fibronectin type II domain and heme domain, and it was evolutionarily closely related to the MMP-9 of Seriola dumerili. Real-time PCR, western blotting, and enzyme activity assay were used to analyze the expression of MMP-9 in P. argenteus under different feeding conditions, in various tissues, and on different feeding days. The results showed that the expression of MMP-9 in group A (fed with jellyfish for the first 20 days) and B’ group (fed with jellyfish for subsequent 15 days) was significantly higher than that in other groups (P < 0.05) and the expression in the kidney was significantly higher than that in other tissues (P < 0.05). The expression increased gradually with the increase in feeding time. The results suggest that MMP-9 expression is induced in P. argenteus fed with jellyfish and plays a very important role in the immune response of the body.

The contamination of fish type products such as silver pomfret fish fillets by potentially toxic elements (PTEs) has raised global health concerns. Related studies regarding the concentration of PTEs in fillets of silver pomfret fish were retrieved among some international databases such as Scopus, PubMed and Embase between 1 January 1983 and 10 March 2020. The pooled (mean) concentration of PTEs in fillets of silver pomfret fish was meta-analyzed with the aid of a random-effect model (REM). Also, the non-carcinogenic risk was estimated via calculating the 95th percentile of the total target hazard quotient (TTHQ). The meta-analysis of 21 articles (containing 25 studies or data reports) indicated that the ranking of PTEs in fillets of silver pomfret fish was Fe (11,414.81 µg/kg wet weight, ww) > Zn (6055.72 µg/kg ww) > Cr (1825.79 µg/kg ww) > Pb (1486.44 µg/kg ww) > Se (1053.47 µg/kg ww) > Cd (992.50 µg/kg ww) > Ni (745.23 µg/kg ww) > Cu (669.71 µg/kg ww) > total As (408.24 µg/kg ww) > Co (87.03 µg/kg ww) > methyl Hg (46.58 µg/kg ww). The rank order of health risk assessment by country based on the TTHQ for adult consumers was Malaysia (2.500) > Bangladesh (0.886) > Iran (0.144) > China (0.045) > Pakistan (0.020) > India (0.015), while the corresponding values for child consumers was Malaysia (11.790) > Bangladesh (4.146) > Iran (0.675) > China (0.206) > Pakistan (0.096) > India (0.077). The adult consumers in Malaysia and children in Malaysia and Bangladesh were at considerable non-carcinogenic risk. Therefore, following the recommended control plans in order to reduce the health risk associated with the ingestion of PTEs via consumption of silver pomfret fish fillets is crucial.

Salinity has been demonstrated to influence the biosynthesis of long-chain (C20–24) polyunsaturated fatty acids (LC-PUFAs) in teleost fish. Since LC-PUFAs are essential nutrients for vertebrates, it is central to understand how fish cope with an acute change in salinity associated with natural events. We herein report on the cloning and functional characterization of two elongation of very-long-chain fatty acid (Elovl)4 proteins, namely, Elovl4a and Elovl4b, and study the roles that these enzymes play in the biosynthesis of LC-PUFAs and very-long-chain (>C24) polyunsaturated fatty acids (VLC-PUFAs) in marine teleost Pampus argenteus. The P. argenteus Elovl4 displayed all of the typical features of Elovl-like enzymes and have eyes and brain as major sites through which they exert their functions. Moreover, functional studies showed that the P. argenteus Elovl4 can effectively elongate C18–22 substrates to C36 VLC-PUFA. Because both P. argenteus Elovl4 are able to produce 24:5n – 3 from shorter precursors, we tested whether the previously reported Δ6 Fads2 from P. argenteus was able to desaturate 24:5n – 3 to 24:6n – 3, a key step for docosahexaenoic acid (DHA) synthesis. Our results showed that P. argenteus can indeed bioconvert 24:5n – 3 into 24:6n – 3, suggesting that P. argenteus has the enzymatic capacity required for DHA biosynthesis through the coordinated action of both Elovl4 and Fads2. Furthermore, an acute salinity test indicated that low-salinity stress (12 ppt) upregulated genes involved in LC-PUFA biosynthesis, with 12 ppt salinity treatment showing the highest hepatic LC-PUFA content. Overall, our results unveiled that the newly characterized Elovl4 enzymes have indispensable functions in LC- and VLC-PUFA biosynthesis. Moreover, acute salinity change influenced the biosynthesis of LC-PUFA in P. argenteus. This study provided new insight into the biosynthesis of LC- and VLC-PUFAs in vertebrates and the physiological responses that teleosts have under acute salinity stress., This study was supported by the National Key R&D Program of China (2018YFD0900400), the Nature Science Foundation of Zhejiang Province (LY17C190002 and Y21C190016), the National Natural Science Foundation of China (31802303 and 32072987), Key Research Program of Zhejiang Province of China (2018C02037), Ningbo Agricultural Major Project (2015C110003), Zhejiang Major Science Project (2019C02059), Natural Science Foundation of Zhejiang Province (LQ20C190005), Natural Science Foundation of Ningbo (2019A610427), and the Industrial Chain Collaborative Innovation Project of the Demonstration Work on Innovative Development of the Marine Economy of the State Oceanic Administration (NBHY-2017-S2).

The silver pomfret (Pampus argenteus) is one of the most commercially important marine fish species in the Bay of Bengal, Indian Ocean. However, detailed information on the reproductive biology of silver pomfret is limited for the Bay of Bengal, Bangladesh. To understand their reproductive biology, especially the gonadal developmental cycle and spawning season, a total of 373 individuals were collected monthly from February 2016 to January 2018 and examined. The total length (TL) and weight (TW) of P. argenteus ranged from 18.82–35.73 cm and 89.26–617.60 g, respectively. The highest gonadosomatic index (GSI) values were observed from April–June with a second (smaller) peak in October. The highest oocyte diameter was observed in May (630.50 ± 96.70 μm), when the fish reached full maturity, and the lowest was observed in July (35.10 ± 7.12 μm), when new eggs began their development for the next spawning season. The maximum number of eggs in the ovary were found in the yolk granule stage in May with a number of post-ovulatory follicles, which indicated that the ovaries developed to a peak leading up to the spawning season. A number of spermatids were also seen in males in April–June along with females. From these detailed observations, it may be concluded that P. argenteus shows two spawning peaks, in May–June and October. This observation will be helpful for the artificial breeding, sustainable management and conservation of this species in the study area.

- Abstract
Freezing fish to prevent fish spoilage. Because microorganisms at temperatures below 18 ° C do not grow and speed of chemical reactions fish at this temperature reaches a minimum. In this project, the effect of freezing on fat oxidation of fish fillets Sparidentex hasta and Pampus argenteus were studied and results were compared together. 10 kg of Sparidentex hasta and Pampus argenteus randomly were purchased from Behbahan city market, respectively, with an average weight (350±2/20g, 750 ±38/15g), after wasing them, the fillets were prepared separately in closed packages in freezer with a temperature of -18 °C for 35, 65 and 95 days were maintained. Men tioned factors such as, TBA, PH, FFA, and peroxide of fresh and frozen samples were tested after each period freezing. The TBA, FFA and pH levels of both species increased in all during storage. Peroxide index in Pampus argenteus reduced but no significant change in Sparidentex hasta in the period. [ABSTRACT FROM AUTHOR]

We studied the effects of dietary n-3 LC- PUFAs on the activities and mRNA expression levels of tissue lipoprotein lipase ( LPL) and fatty acid synthase ( FAS) during vitellogenesis and ovarian fatty acid composition in female silver pomfret broodstock. Broodstock were fed one of four experimental diets for 185 days: FO (100% fish oil), FSO (70% fish oil + 30% soybean oil), SFO (30% fish oil + 70% soybean oil) or SO (100% soybean oil). The results revealed that hepatic LPL and FAS and ovarian FAS activities and mRNA expression levels significantly increased at vitellogenesis and postvitellogenesis relative to previtellogenesis, with no significant differences between these two stages, except for hepatic LPL mRNA expression. Dietary n-3 LC- PUFAs decreased tissue FAS and increased LPL activities and mRNA expression levels. The ovarian concentrations of 20:4n-6 ( ARA), 20:5n-3 ( EPA), 22:6n-3 ( DHA) and n-3 LC- PUFAs were directly influenced by n-3 LC- PUFA levels. Total n-3 LC- PUFA concentrations in SO were 57% lower than those in FO, while 18:2n-6 concentrations in SO were 4.7 × higher than those in FO. These results revealed that high dietary n-3 LC- PUFAs levels significantly affected tissue lipid metabolism in female silver pomfret broodstock during vitellogenesis by upregulating LPL and downregulating FAS.

In this study changes in fatty acids profile during frozen storage at -18°C for (Pampus argenteus) and (Sparidentex hasta), caught from the Persian Gulf (Bandar Deylam) were studied. Changes in saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), polyunsaturated fatty acids (PUFAs), EPA+DHA/C16, n-3/n-6 and high unsaturated fatty acids (HUFA) were investigated during 95 days storage at -18°C. Twenty fatty acids were found in (Pampus argenteus) with high percentage of saturated fatty acids (44.06%), polyunsaturated fatty acids (32.17%), high unsaturated fatty acids (27.8%) and monounsaturated fatty acids (22.62%) and for (Sparidentex hasta) found high percentage of PUFA(41.39%), HUFA (37.35%), SFA (36.42%) and MUFA (21.76%). The percentage of Fatty acids of SFA and PUFA in fish Sparidentex Hasta during this study did not show a significant difference. The percentage of MUFA fatty acids and HUFA during the freezing period were varied so that the maximum amounts of MUFA and HUFA were found on 65 and 0 day respectively. The fish Pampus Argenteus were found also the highest percentage of fatty acids of SFA, PUFA and HUFA during freezing on the days 65 and 35, but for MUFA no significant difference during freezing. Percentage of palmitic acid were found (28.06% and 23.72%), stearic acid (7.84% and 10.21%) in Silver pomfret and Progies respectively. The major unsaturated fatty acids of Silver pomfret and Progies were determined as DHA (19.87% and 22.57%), oleic acid (15.02% and 14.55%) respectively. As a result of the frozen storage (up to 95 days), fatty acid groups such as polyunsaturated, high unsaturated and n-3 polyunsaturated, as well as in the n-3/n-6 ratio were decreased and it means that the nutritional value of Silver pomfret and Progies has decreased.

Pomfrets (Genus Pampus ) are commercially important fishes in the Indo Pacific region. The systematics of this genus is complicated due to morphological similarities between species. The silver pomfret from Indian waters has long been considered to be Pampus argenteus . The objective of the study was to utilize the mitochondrial COI gene to establish the molecular identity of the silver pomfret distributed in Indian waters and to resolve the phylogenetic relationships among Pampus species in the world based on sequence data in the NCBI database. Seven valid Pampus species are identified in this study. The mean genetic divergence value calculated between clades representing these species was 7.9%. The mean genetic distance between the so-called Pampus argenteus from Indian waters and sequences attributed to P. argenteus from the South China Sea, where the neotype of this species was collected, was found to be greater than 12%, strongly supporting the likelihood of the Indian species being distinct. The Indian Pampus species show very close affinity to P. cinereus , with inter species differences less than 2%. The taxonomic identity of the silver pomfret in India is also discussed here, in light of molecular and morphological evidence. [ABSTRACT FROM AUTHOR]

Toll-like receptors (TLRs) play important roles in the innate system by recognizing pathogen-associated molecular patterns derived from various microbes. In this study, we reported the cloning and identification of paTLR3 and paTLR4 interactor with leucine rich repeats (TRIL) cDNA from silvery pomfret (Pampus argenteus). The full-length paTLR3 and paTRIL cDNA were 2996 and 3163 bp long, respectively. Both of the two proteins contained many LRR domains, one LRR-C terminal domain and one transmembrane region, which fits with the characteristic TLR and its analogue domain architecture. Phylogenetic analyses revealed that paTLR3 and paTRIL shared the closest relationship with Lateolabrax japonicas and Notothenia coriiceps, respectively. The expression levels of paTLR3 and paTRIL varied greatly among the examined tissues with the highest expression both in liver. Following exposure to V. anguillarum flagellin, A. hydrophila lipopolysaccharide (LPS) and L. plantarum lipoteichoic acid (LTA), paTLR3 and paTRIL were all up-regulated. V. anguillarum flagellin induced the highest expression levels of paTLR3 and paTRIL. A. hydrophila flagellin and A. hydrophila LPS induced the highest expression levels of IL-1β and IL-8, respectively. The present results will provide the valuable information for understanding the structure, function and the immune defense process of paTLR3 and paTRIL in silvery pomfret.

Pampus argenteus (Perciformes: Stromateidae) is an economically important benthopelagic fish, which is widely distributed along the coast of China, Indian Ocean, Arabian Gulf and North Sea. To benefit population genetics studies and resource management, 26 pairs of novel microsatellite loci of P. argenteus were isolated using combined biotin capture method. These loci all included di-nucleotide repeat motifs. All markers showed polymorphism when assessed in 30 individuals from Xiapu population. The number of alleles per locus (NA) ranged from 4 to 22, and polymorphism information content (PICs) were from 0.565 to 0.924. Mean values of observed (HO) and expected (HE) heterozygosities ranged from 0.267 to 1.000 and from 0.633 to 0.929, respectively. Cross-species amplification showed that 22 microsatellite markers were successfully amplified in 30 individuals of P. minor, a closely related species of P. argenteus, and indicated clearly polymorphisms. The markers developed in this study will provide a useful tool for investigating the genetic structure, gene flow, and mating system of P. argenteus and the closely related species. They will also facilitate study on their evolutionary responses to the ongoing coastal systems change.

For many fish stocks, such as Pampus argenteus and Setipinna taty in China, size composition data are more accessible than catch data. Varied results can arise when different length-based stock assessment models are applied to these data, and fishery managers often need to reconcile conflicting estimates of population status. Superensemble modeling, a relatively recent innovation in fish stock assessments commonly used in other fields, may provide an effective solution to resolving uncertainties among the results from multiple length-based models. To verify potential for this approach to improve estimates of population status, we applied ensemble modeling to fit simulated data of P. argenteus and S. taty in the Bohai and Yellow Seas using predictions from a length-based integrated mixed effects (LIME) and length-based spawning potential ratio (LB-SPR) models as covariables in a superensemble model developed in this study. All simulation modeling of P. argenteus and S. taty in the Bohai and Yellow Seas was conducted using the operating model in the R package LIME. Initially, the LIME and LB-SPR performances were tested separately under three scenarios of fishing mortality and recruitment variability (“equilibrium scenario,” “endogenous scenario,” and “one-way base scenario”). Then, estimates of spawning potential ratio (SPR) were combined with the superensemble models (a linear model, a support vector machines, a random forest and a boosted regression tree). We trained our superensemble models with 80% of the simulated data and tested them with the remaining 20%. Our results showed that superensemble modeling substantially improved the estimates of SPR, with support vector machines performing the best at estimating population status: precision improved by 12.7% for S. taty and 8% for P. argenteus on average (namely, median absolute proportional error decreased by 0.127 and 0.08 on average) compared to the individual models. This finding has important implications for fisheries management in the context of species for which catch data are unavailable. Applying the size composition survey data, the results from support vector machines superensemble model suggested that neither S. taty nor P. argenteus in the Bohai Sea in 2019 are overfished, but the stock status of P. argenteus warrants vigilant monitoring.

A total of 162 specimens of Silver Pomfret (Pampus argenteus) including 38 samples from Kuwait and 124 samples from Iran (24 from Khouzestan, 24 from Chabahar and 38 from Bushehr) were examined for their DNA structure. DNA from all specimens was extracted using the Phenol-chloroform and amplified using PCR method with a pair of primers with ND2 gene sequence. The PCR products were abowt 1300 (bp) for all samples. For RFLP analysis 16 restriction enzymes Bel I, Pst I, Acc II. BseN I, Tru I, Dra I, Alw26 I, Hin6 I, Tas I, Alu I, EeoR I ,Hae III, Hine II. Hind III. Hinf I and Hpa II were used. DNA bands were visualized by Gel electrophoresis (polyacrylamid) and staining with silver nitrate. Out of 16 enzymes, four showed polymorphism that includedg Hinf I, Alu I, Ace II, and Hpa II. Of the total 162 samples, 13 showed polymorphic patterns. Six haplotypes were rare occurring only once, but others which were only four different kinds occurred more than once. The REAP test gave no significant result for the examined regions (P>0.05). Therefore, our results revealed that the Pampus argenteus stocks in the Persian Gulf and Oman Sea of Iranian and Kuwaiti waters constitute a unique population.

Silver pomfert (Pampus argenteus) belongs to Stromatidae family and is considered an important commercial fish found in some major fishing grounds of the Hormozgan province waters. The stomach contents of 853 collected specimens were investigated from June 2001 to November 2002. The change in stomach content relative to the length classes and gonad stages, vacuity index, gastro-somatic index and frequency percentage of different food items were also studied. The diet consisted of a broad spectrum of food types, but crustaceans (especiallycopepods) were dominant. The next major food group was Bacillarlphyceae (16 genera), followed by Cyanophyceae (6 genera) and mollusks. Other major groups were Nematodeworms, Foraminifera and Dinophyceae (6 genera). Copepods were the primary and main food items with the Bacillarlophyceae being the second most important prey. Therelationship between stomach contents and maturity stages in females showed that the food take up increased during adult stages and then decreased during spawning periods. The vacuityindex (CV) was calculated as 14.49, indicating the voracity of Pampus argenteus. The gastro-somaticindex was estimated to be 4.5 based on monthly and maximum values during February.

Amyloodinium ocellatum (AO) infection in silver pomfret (Pampus argenteus) causes extensive mortality. Insufficient information exists on the molecular immune response of silver pomfret to AO infestation, so herein we simulated the process of silver pomfret being infected by AO. Translucent trophosomes were observed on the gills of AO-infected fish. Transcriptome profiling was performed to investigate the effects of AO infection on the gill, kidney complex and spleen. Overall, 404,412,298 clean reads were obtained, assembling into 96,341 unigenes, which were annotated against public databases. In total, 2730 differentially expressed genes were detected, and few energy- and immune-related genes were further assessed using RT-qPCR. Moreover, activities of three immune-related (SOD, AKP and ACP) and three energy-related (PKM, LDH and GCK) enzymes were determined. AO infection activated the immune system and increased interleukin-1 beta and immunoglobulin M heavy chain levels. Besides, the PPAR signalling pathway was highly enriched, which played a role in improving immunity and maintaining homeostasis. AO infection also caused dyspnoea, leading to extensive lactic acid accumulation, potentially contributing towards a strong immune response in the host. Our data improved our understanding regarding the immune response mechanisms through which fish coped with parasitic infections and may help prevent high fish mortality in aquaculture.

Due to their high-water content and low nutritional value, jellyfish have long been considered 'dead ends' in marine food webs. However, it was revealed that silver pomfret (Pampus argenteus) preferentially hunts jellyfish, and consuming jellyfish alters intestine histology. To better understand the physiological responses of midgut tissues after consuming jellyfish, we compared the transcriptomes and proteomes of jellyfish-fed and jellyfish-unfed groups, and identified 1167 differentially expressed genes (DEGs) and 471 differentially expressed proteins (DEPs). Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis showed that unsaturated fatty acid metabolism pathways, especially cholesterol metabolism, were the most enriched biological pathways. Apolipoprotein E was downregulated at both transcriptome and proteome levels, and it was found to negatively regulate jellyfish consumption. These results provide deep insight into the molecular mechanisms regulating jellyfish consumption in Pampus argenteus. • Eating jellyfish has a dramatic impact on the gut histology of silver pomfret. • Only 29 DEGs and DEPs overlapped. • Cholesterol metabolism plays a central role after consuming jellyfish. • ApoE negatively regulates jellyfish consumption.

• Pampus argenteus samples are collected from three locations in China. • Trachinotus ovatus samples are collected from four locations in China. • Multi-element and stable isotope analysis are used to trace sample origins. • The farmed Trachinotus ovatus in different regions have well distinguished. This study aimed to determine whether Trachinotus ovatus and Pampus argenteus could be differentiated by multi-element composition or stable isotope ratio analysis of δ13C and δ15N. The multi-element analysis values of a total of 60 Pampus argenteus samples from three sites and 60 Trachinotus ovatus samples from four sites around China were determined, and the other 60 samples of Pampus argenteus and 51 samples of Trachinotus ovatus were tested by principal component analysis (PCA) to estimate the accuracy of origin identification. The results showed that the cross-validation accuracy rate is 92.2% for the Pampus argenteus and 98.3% for the Trachinotus ovatus. Stable isotope analysis of δ13C and δ15N also can distinguish Trachinotus ovatus from different geographical origins. These results showed that the usefulness of multi-element and stable isotope analysis as indicators for authenticating the geographical origin of two pomfrets in China. [ABSTRACT FROM AUTHOR]

Two essential metal contaminations were studied in a total of sixty silver pomfret Pampus argenteus samples. The purpose of the current study was to evaluate the levels of Zn and Cu in the muscle tissues of the commercial species P. argenteus in the fishing harbour of Karachi, the most important in Pakistan, and to correlate the concentration of metals with respect to fish size. Moreover, this study sought to establish the potential risk to humans from consumption of fish samples contaminated with these heavy metals. Zn concentrations in the silver pomfret were higher than Cu. The ranges of Zn and Cu concentrations were found to be from 2 to 12 and 1 to 6 mg/kg dry wt., respectively. The differences in both Zn and Cu concentrations between seasons were statistically significant. These results can be used to provide baseline information for risk assessment associated with their consumption, as the Estimated Daily Intake (EDI) for the fish tissues and Zn and Cu levels were below the daily dietary allowance recommended by international standards. Therefore, it may be concluded that these metals should not pose any health threat to the consumers resulting from the consumption of the fish. The relationship between Zn and Cu levels and fish size (both length and weight) of the fish were minimal, indicating that metal concentration in fish tissues was independent of lengths and weights.

Silver pomfret, Pampus argenteus, is a fish species from coastal waters. Despite its high commercial value, this edible fish has not been sequenced. Hence, its genetic and genomic studies have been limited. We report the first draft genome sequence of the silver pomfret obtained using a Next Generation Sequencing (NGS) technology. We assembled 38.7 Gb of nucleotides into scaffolds of 350 Mb with N50 of about 1.5 kb, using high quality paired end reads. These scaffolds represent 63.7% of the estimated silver pomfret genome length. The newly sequenced and assembled genome has 11.06% repetitive DNA regions, and this percentage is comparable to that of the tilapia genome. The genome analysis predicted 16 322 genes. About 91% of these genes showed homology with known proteins. Many gene clusters were annotated to protein and fatty-acid metabolism pathways that may be important in the context of the meat texture and immune system developmental processes. The reference genome can pave the way for the identification of many other genomic features that could improve breeding and population-management strategies, and it can also help characterize the genetic diversity of P. argenteus.

Silver pomfret fish (Stromateidae) is a family of Perciformes order. One species of this family is Pampus argenteus known as silver pomfret and lives in different parts of the Persian Gulf and Gulf of Oman. Therefore, the genetic relationship between its populations is so important. In this study, eight samples of Pampus argenteus were collected from four locations involved: Emam Khomeyni, Bushehr and Bandar Abbas in Persian Gulf and Chabahar in Gulf of Oman. Cytochrome b gene and D-loop region of mitochondrial DNA on these samples are analyzed. These genes are carried out using PCR with specific mtDNA primers and sequenced. Then, the evolutionary history was inferred by using the maximum-likelihood method. Evolutionary analyses were conducted in MEGA7. According to the phylogenetic trees, with translocations in Persian Gulf to Gulf of Oman, similarity decreases slowly. Chabahar1 sample in phylogenetic tree of cytochrome b is phylogenetically near China Sea samples. The reason may be migration from ocean to gulf throughout the centuries and Chabahar is in Gulf of Oman and locationally near the Arabian Sea and Indian Ocean. In D-loop region, results are similar to cytochrome b excepting one sample (Emam Khomeyni1). D-Loop in samples shows modification more than cytochrome b for the reason absence of protein product.

A cell line (PaF) derived from the fin tissue of silver pomfret (Pampus argenteus) was established and characterized in this study. The cell line has been subcultured for more than 50 times in Dulbecco's modified Eagle's medium (DMEM) containing 15% foetal bovine serum (FBS) since the initial primary culture. PaF cells grew well at temperatures from 24°C to 28°C in DMEM supplemented with 15% FBS. Partial amplification and sequence analysis of the cytochrome B gene indicated that PaF originated from silver pomfret. Cytogenetic analysis demonstrated that the modal chromosome number was 48. A significant cytopathic effect was observed in PaF cells during viral haemorrhagic septicaemia virus (VHSV) infection, and the VHSV replication was confirmed by qRT-PCR and viral titre assays. In contrast, PaF cells were resistant to red-spotted grouper nervous necrosis virus infection. Moreover, PaF cells could respond to VHSV and lipopolysaccharide treatments, as indicated by the expression of immune-related genes, TLR5 and TLR9. In conclusion, the establishment of PaF cell line will provide an appropriate in vitro tool for the study of mechanisms of pathogen-silver pomfret interaction.

Pomfret, which are widely distributed throughout the western Pacific and Indian Oceans, are economically important fish species. As their similar external morphological characteristics can inhibit proper species identification, numerous errors exist in the morphological characterization and DNA barcoding data of pomfret. In this study, we extensively sampled pomfret from the Indian and Pacific Oceans. Using the sampled specimens, in combination with morphological assessments, DNA barcoding, and corrected sequences of the mitochondrial cytochrome c oxidase I (COI) gene in GenBank, we attempted to resolve the classification issues surrounding this group. We identified seven valid species in the genus Pampus, of which all seven are distributed in the western Pacific and three are distributed in the Indian Ocean. Pampus argenteus, Pampus cinereus, and Pampus sp. were identified as three valid species with relatively close genetic distances and sharing a common ancestor. Significant variation between Pampus chinensis specimens from the Arabian Sea and the northwestern Pacific suggest a possible species complex. Finally, we provide an identification key to facilitate the identification of pomfret based on the major diagnostic morphological characteristics of six Pampus species collected along the western Pacific coast. On the basis of the reports on the new record of “Pampus argenteus,” we found that the Lessepsian migration of pomfret was likely, with species from the Indian and Pacific Oceans spreading through the Mediterranean Sea into the waters of the eastern Atlantic. Further study is required to clarify the validity of the newly recorded “Pampus argenteus.”

PFAAs have emerged as persistent organic pollutants (POPs) in a variety of environmental matrixes and biota, posing potential hazards for wildlife and humans. Diet has been considered as an important source for human exposure to PFAAs and seafood accounts for a relatively large proportion in human diets, especially for coastal residents. In an effort to clarify the impact of PFAAs in seafood on human health, 17 PFAAs were determined in 42 pooled seafood samples (14 species) from the Yellow Sea areas, China. The concentrations of total PFAAs (sum of 17 PFAAs, ∑PFAAs) were in the range of 1.10–1067 ng/g dry weight (dw), with the highest concentration found in swimming crab (Portunus trituberculatus) and the lowest in silvery pomfret (Pampus argenteus). Concentrations and composition profiles of PFAAs varied significantly among different species, suggesting that bioaccumulation potential of PFAAs differed from species to species. The distinct spatial distribution of PFAAs in four categories of seafood could be mainly attributed to the contamination patterns of PFAAs in three nearby cities. PFBA was presented as the most abundant PFAA in this study, which was different from the findings in many other studies where PFOS was the predominant compound. Furthermore, the human health risk assessment suggested that a comprehensive action plan is needed to protect people from high exposure to PFAAs through seafood consumption.

Formaldehyde can effectively control ectoparasites in silver pomfret (Pampus argenteus). However, there is limited information on the effects of formaldehyde treatment at a molecular level in fishes. In the present study, transcriptome profiling was conducted to investigate the effects of formaldehyde treatment (80 mg/L, bath for 1 h every day for three consecutive days) on the liver and kidney tissues of silver pomfret. A total of 617959982 clean reads were obtained and assembled into 265760 unigenes with an N50 length of 1507 bp, and the assembled unigenes were all annotated by alignment with public databases. A total of 2204 differentially expressed genes (DEGs) were detected in the liver and kidney tissues, and they included 7 detoxification- related genes and 9 immune-related genes, such as CYP450, GST, MHC I & II, and CCR. In addition, 1440 DEGs were mapped to terms in the GO database, and 1064 DEGs were mapped to the KEGG database. The expression of 4 detoxification-related genes and 6 immune-related genes in three days formaldehyde treatment were analyzed using RT-qPCR, and the antioxidant enzyme levels were also determined. The results indicate differential expression of detoxification- and immune-related genes during the three days formaldehyde treatment. Our data could provide a reference for the treatment of parasites to avoid high mortality and help in understanding the molecular activity in fishes after formaldehyde exposure.

Effects of high hydrostatic pressure‐assisted thawing (HPAT, 100, 150, and 200 MPa) on the physicochemical characteristics of silver pomfret were evaluated in comparison with conventional (water immersion thawing, WIT) thawed samples. HPAT significantly decreased the thawing time, as well as the cooking and total losses. The maximum water holding capacity was observed at 100 MPa. Color changed obviously at ≥150 MPa, resulting in a cooked appearance. Samples thawed with HPAT showed better texture quality and lower lipid oxidation. The levels of myofibrillar protein oxidation and surface hydrophobicity increased, while Ca2+‐ATPase activities decreased as the pressure increased. The oxidation of myofibrillar protein was significantly decreased at 100 MPa; total sulfhydryl content was 30.85% higher than that of WIT. Overall, 100 MPa is the optimum treatment condition for silver pomfret thawing without negative effects on quality of the product. HPAT can be a potential alternative to produce high‐quality thawed fish.

Many fish species are known to feed on jellyfish. Herein, we observed the effects of jellyfish feeding on silver pomfret using gas chromatography tandem time-of-flight mass spectrometry (GC-TOF–MS) based on metabolomics. We studied the effects of feeding on jellyfish on skin and serum immune of silver pomfret. Healthy silver pomfret (initial weight, 13.40 ± 1.565 g) was divided into two groups: control and feeding. The pomfrets were fed jellyfish at 2, 6, 12, 24, and 72 h, and samples were obtained. Statistical analysis revealed that after jellyfish feeding, most serum immune indicators did not show a significant change; however, skin immune indicators indicated that silver pomfret elicit a stress response on encountering jellyfish, gradually adapting to their presence. We therefore conducted further experiments involving two groups: group A, which was not fed any extra jellyfish, and group B, which was fed extra jellyfish (approximately 10% weight of silver pomfret) every day for 60 days. Orthogonal partial least squares discriminant analysis led to the identification of stronger biomarkers, with the liver metabolome showing obvious variations between the groups (group B vs. A). After feeding jellyfish by silver pomfret, some amino acids, amines, and unsaturated fatty acids in the liver tissue showed a significant increase. Our results, thus, not only reveal changes in physiological indices of silver pomfret after feeding on jellyfish but also provide a new idea for further optimizing the feed formula for silver pomfret culture.

Jellyfish are sometimes considered as valueless because of their supposed low nutritive content. Here, we conducted feeding experiments on silver pomfret juveniles to evaluate the dietary value of jellyfish. Six treatments, including a starvation treatment (S) and five feeding treatments, with Aurelia aurita ( AA), Rhopilema esculentum ( RE), artificial diet (AD), both A. aurita and artificial diet ( A&A), and both R. esculentum and artificial diet ( R&A), were carried out to compare fish survival rates and growth performance. Fish with S treatment showed a 48% mortality rate and reduced body weight, whereas fish with AA and RE treatments showed no death and much increased body weight. Fish with A&A and R&A treatments exhibited a much faster growth than that with AD treatment. Further, the effects of diet on biochemical composition of silver pomfrets were explored. Monounsaturated fatty acid (MUFA), seven different fatty acids, and six different essential amino acids (EAAs) were showed to be good indicators to assess silver pomfrets' response to their prey. Our experiment indicated that the jellyfish, A. aurita and R. esculentum, can provide energy for silver pomfrets' metabolism and growth, and as supplemental food are suitable for rearing silver pomfret juveniles.

Silver pomfret, Pampus argenteus is an economically important seafood species. The fishery resource of pomfret in Indian waters shows a dwindling catch since the last few years and the pomfrets caught were mostly undersized which calls for immediate attempts for management of resources. An accurate definition of population structure is important for management of this species. The genetic stock structure of P. argenteus distributed along Indian coast was identified using analysis of 842 bp of complete ATPase 6/8 genes of mitochondrial DNA. Altogether, 83 silver pomfret ( P. argenteus) collected from 4 locations along Indian coast (Gujarat, Kerala, Tamil Nadu and West Bengal) were sequenced. Twenty four haplotypes were identified among 83 individuals with haplotype diversity (0.87) and nucleotide diversity (0.0025). The significant pair-wise FST and AMOVA values, between samples from West Bengal (east coast) and other locations along the west coast (Gujarat and Kerala) indicated the occurrence of distinct population structure in silver pomfret along the coast.

The study was conducted to provide baseline information on nine trace elements in three commercially significant fish species (Pampus argenteus, Sardinella longiceps, and Tenualosa ilisha) collected from four stations of coastal areas and five rivers of Bangladesh. The concentrations of Pb and Cd in most of the stations exceeded the maximum recommended limits proposed by different recognized organizations. High trace element contamination was observed in coastal areas, mainly in Kuakata, more than in rivers. The estimated daily intake (EDI), target hazard quotient (THQ), and hazard index (HI) indicated potential human health risk due to elevated concentrations of Pb exposure. The target cancer risk (TR) values of Cd suggested cancer risk to the inhabitants of coastal areas (especially Kuakata), thus becoming an issue of concern on public health of Bangladesh.

Salim G, Handayani KR, Indarjo A, Ransangan J, Atieqah N. 2020. Growth, mortality and exploitation rate of Pampus argenteus, Parastromateus niger and Scomberomorus commerson in Sebatik Waters, Indonesia. Biodiversitas 21: 5363-5372. The economic revenue of the local government of the Indonesian Sebatik Island relies much on the exploitation of its rich marine biodiversity. One of the important economic activities is the capture fisheries of commercially important fishes such as the white pomfret (Pampus argenteus) and black pomfret (Parastromateus niger), and mackerel fish (Scomberomorus commerson). The current study aims to estimate the growth, condition factor, and exploitation rate of the fish species for developing sustainable fishery management. Fish samplings were conducted in the Sebatik Waters, Nunukan District, North Kalimantan Province, Indonesia from June to July 2020. The fish were caught using gillnet at daytime (pomfrets) and nighttime (mackerel), respectively. Then, 82, 73, and 83 specimens of white pomfret, black pomfret, and mackerel were randomly selected for the length-weight relationship, condition factor, and exploitation rate analysis, respectively. The results revealed that the size distribution of the white pomfret population in the coastal waters of Sebatik Island ranged from 220.0 to 351.0 mm, black pomfret ranged from 231.0 to 362.0 mm and mackerel, ranged from 242.0 to 432.0 mm. All the fish species exhibited negative allometric (b50%) and fishing mortality (>60%) of all the fish species analyzed in this study indicate that there is a sign of overfishing to these fish resources in the coastal waters of Sebatik island. Hence, sustainable fishing management is timely needed to prevent depletion of these important fishery resources. Such management can include fishing restrictions for small-sized and first mature fish, close fishing season, and strict requirement for fishing permits.

The current study explored Aurelia aurita and Rhopilema esculentum consumption by silver pomfret juveniles, as well as their prey selection between the two jellyfish species. Silver pomfret juveniles weighing 1±0.1 g actively preyed on both the species. Their daily A. aurita consumption was 11.6 times their own body weights regardless of the size of A. aurita medusae. Their daily R. esculentum consumption was 13, 9.1, 5, and 4.1 times their own body weights when the R. esculentum medusae were 10, 20, 30, and 40 mm in bell diameter, respectively. The survival rates of the R. esculentum were higher than those of the A. aurita. When the R. esculentum medusae were more than 30 mm in bell diameter, their survival rate exceeded 92%. Silver pomfrets serve as a type of potential predators on A. aurita in coastal waters, and they have little influence on R. esculent um with a size exceeding 30 mm. Besides, A. aurita may be able to be used as fish prey in silver pomfret artificial breeding. [ABSTRACT FROM AUTHOR]

Fish is a food that is consumed by many people because fish contain high nutrition. Fillet products are diversification of fishery products that are quite popular with the community. That is because fillet products are easy to consume and have good nutritional content. However, fish fillet products are easily degraded during transportation. So that triggers traders to use hazardous materials in the form of formalin to increase the shelf life of fillet products. The shelf life of fish fillet products needs to be improved in order to obtain good quality and not be easily damaged by storing fillets at low temperatures and the addition of active ingredients in the form of honey. Honey also has antimicrobial properties so that it can be used as a food preservative. Honey can inhibit the growth of bacteria that cause decay. The purpose of this study was to determine the effect of adding honey with different concentrations on the shelf life of white pomfret (Pampus argenteus) fillets at cold temperatures. This research was experimental by making honey solutions with different concentrations (0%: 10%; 11%). This research uses a completely randomized design (CRD). The shelf life test is done by calculating the value of TPC, Protein, pH, Tvbn, and organoleptic. TPC, Protein, pH, TVBN, and organoleptic test results showed that the addition of honey with different concentrations had a significant effect on the shelf life of white pomfret fish fillets. The best concentration of adding honey is at a concentration of 5%. While the shelf life that can be accepted by consumers can reach 6 days shelf life. The results showed that honey can be used as an alternative preservative in fish fillet meat that functions as an antimicrobial and fat oxidation prevention.

Hoxc6 gene can be described as having roles in axial patterning in early embryogenesis, and in at least some species, having a contribution to limb positioning. In this study, we cloned and characterised Pampus argenteus Hoxc6. The highly conserved HOXC6 protein sequence contains a homeodomain and a low-complexity region. Expression of Hoxc6 mRNA was measured at different developmental stages and in different tissues by real-time PCR (p 0.05), and was high during eye capsule and brain differentiation stages, but low in 7 and 13-day-old larvae. Hoxc6 mRNA was more abundant in fin tissue than brain and eye tissues. Western blotting showed that HOXC6 protein levels were high at embryonic stages, but decreased significantly in 7, 13, 16 and 19-day-old larvae, and levels were essentially consistent with those of mRNA measured by real-time PCR in different tissues. In situ hybridisation showed that the Hoxc6 transcript was strongly expressed in the whole brain and anterior part of the body axis in 1-day-old larvae, but in the hindbrain, pectoral fin, mandible and hypothetical pelvic fin region in 7, 13, 16 and 19-day-old organisms. These results clarify the expression and localisation characteristics of Hoxc6 gene in P. argenteus, and provide a theoretical basis for the molecular mechanism of pelvic fin loss in silver pomfret.

Abstract: Sequence variation of the mitochondrial control region in silver pomfret (Pampus argenteus) among six populations from the Indo-West Pacific region was analyzed. A total of 309 polymorphic sites were detected in the 464–466 bp segment of the control region among 165 individuals which defined 72 haplotypes. Haplotype diversity was ranged from 0.800 to 0.943 and nucleotide diversity ranged from 0.333% to 1.886%. Genetic distance and the fixation index indicated significant differences among populations in different geographical groups (P < 0.05). Median-joining network analysis data showed distinct patterns of phylogeographic structure. The present results suggested that P. argenteus populations have developed significant genetic structure, especially among geographically isolated groups. [Copyright &y& Elsevier]

- Abstract
Background: Silver pomfret ( Pampus argenteus ) is one of the most widely distributed and economically important pelagic fish species. However, an unique morphological feature of P. argenteus is the loss of pelvic fins, which can increase the energy requirement during food capture to some extent and is therefore not conducive to artificial culture. Tbx4/5 genes are highly conserved regulatory factors that regulate limb development in vertebrates and are in turn regulated by microRNAs (miRNAs). However, the miRNAs that directly regulate the Tbx4/5 genes in P. argenteus remain to be elucidated., Methods: The Tbx4/5 genes of P. argenteus were first cloned, and the small RNA transcriptomes were sequenced by high-throughput sequencing during the critical period of the fin development at days 1, 7, and 13 of hatching. The miRNAs regulating the Tbx4/5 genes of P. argenteus were subsequently predicted by bioinformatics analysis, and the related miRNAs were verified in vitro using a dual fluorescence reporter system., Results: A total of 662 miRNAs were identified, of which 257 were known miRNAs and 405 were novel miRNAs were identified. Compared to day 1, 182 miRNAs were differentially expressed (DE) on day 7, of which 77 and 105 miRNAs were downregulated and upregulated, respectively, while 278 miRNAs were DE on day 13, of which 136 and 142 miRNAs were downregulated and upregulated, respectively. Compared to day 13, four miRNAs were DE on day 7, of which three miRNAs were downregulated and one miRNA was upregulated. The results of hierarchical clustering of the miRNAs revealed that the DE genes were inversely expressed between days 1 and 7, and between days 1 and 13 of larval development, indicating that the larvae were in the peak stage of differentiation. However, the number of DE genes between days 7 and 13 of larval development was relatively small, suggesting the initiation of development. The potential target genes of the DE miRNAs were subsequently predicted, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses of target genes were performed. The results suggested that the DE miRNAs were involved in growth, development, and signal transduction pathways, of which the Wnt and Fgfs signaling pathways are known to play important roles in the growth and development of fins. The results of dual fluorescence reporter assays demonstrated that miR-102, miR-301c, and miR-589 had a significant negative regulatory effect on the 3'-UTR of the Tbx4 gene, while miR-187, miR-201, miR-219, and miR-460 had a significant negative regulatory effect on the 3'-UTR of the Tbx5 gene. Altogether, the findings indicated that miRNAs play an important role in regulating the growth and development of pelvic fins in P. argenteus . This study provides a reference for elucidating the interactions between the miRNAs and target genes of P. argenteus in future studies., Competing Interests: The authors declare that they have no competing interests., (© 2022 Zhang et al.)
