The inherent drawbacks of morphology-based identification systems have made it imperative to develop trustworthy genetic techniques that permit the unambiguous identification of fish species. In the present study, seven specimens of the goatfish Upeneus pori Ben-Tuvia and Golani, 1989, were recorded (February 2021) for the first time from the Odisha coast, Bay of Bengal, India. Their DNA was isolated, and mtCOI barcode regions of four specimens were amplified and sequenced successfully. The generated barcode sequences were analyzed using different molecular approaches. U. pori exhibited low genetic variation within populations (average K2P distance = 0.0046). The median joining network of U. pori was simple, with only five haplotypes, including one haplotype present in this region. The analysis of the variation of the amino acids in the mtCOI barcode sequences suggested that there were no significant variations found among U. pori of different geographical locations. The species U. pori was diverged from its common ancestor during the late Miocene sub-epoch, which was around 6.38 Mya. These findings provide insights into the population genetics and evolutionary history of U. pori in this region.","PeriodicalId":36569,"journal":{"name":"Genetics of Aquatic Organisms","volume":"121 31","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141820902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The highest nucleotide sequence divergence occurred between sequenced H. nobilis N3 and reference H. molitrix from India which was 1.208 and the lowest nucleotide divergence occurred in sequenced H. nobilis N1 and sequenced H. molitrix M3 with their reference counterparts from Bangladesh, India and China (0.002). The phylogenetic tree analysis showed that one of the H. nobilis (H. nobilis N3) formed a sister group with H. molitrix M2 with 100% sequence similarities. Otherwise, all sequenced and reference H. molitrix and H. nobilis showed separate clade in the tree. Therefore, we can conclude that the exotic H. molitrix and H. nobilis maintain distinct population status with lower genetic variation.

This species is an important economic and cultural resource for the region since it lives in Lake Van, one of the world's largest sodic lakes. It is often not possible to determine the sex of fish based on morphological characteristics. In this study, landmark-based geometric and morphometric method was preferred to identify the shape difference between male and female sexes of pearl mullet fishes species in Lake Van. A total of 100 pearl mullet fish (50 females and 50 males) were used as material. Significant morphological differences were found between the male and female sexes (P<0.001 in canonical analysis of variance). These differences were found that the male fishes were longer than the female fishes on the lateral side and the head of the male fishes were larger than the female fishes. In addition, female fishes formed a deeper abdominal line towards the ventral side in the wireframe graph. The presence of a large gill positioned cranially is another important feature that distinguishes female fishes from male fishes. Lateral and ventral body differences between the sexes were statistically determined by ANOVA test results.","PeriodicalId":36569,"journal":{"name":"Genetics of Aquatic Organisms","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135785714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this research gap, in the current study dark mahseer collected from Himalayan stream in India (29°21`99.5` N and 79°33`23.9` E) were examined for their morphometric, meristic, osteological, and molecular characteristics. This study discovered unique features of dark mahseer, including its thin non-hypertrophied lower lip without median lobe, complete post-labial groove, 33 to 34 central perforated lateral line scales, a dark elliptical blotch at the angle of the operculum, and numerous fine black dots on a crescent pattern on scales.

Median-Joining analysis indicate presence of two main groups of haplotypes, representing P. proximus and P. brachiomastus + P. simulans, respectively. These data support that P. brachiomastus and P. simulans are conspecific. Mismatch distribution analysis showed population growth for P. brachiomastus at the south of Russian Far East.

Haplotype clustering and the presence of unique haplotypes were identified by phylogenetic and network analysis. Six haplotypes were identified for D. filamentosa and ten for P. maculatus. The neutrality estimations of the upstream and midstream populations of the species revealed the presence of an excess of common alleles with neutral mutations indicating a population expansion after bottleneck and stabilizing selection. The downstream population revealed the presence of an excess of rare alleles with non-neutral mutations indicating a positive directional selection and population sub-division. Population expansion demonstrated star-like phylogenies with rare haplotypes separated by mutational steps from the ancestral haplotypes.

The main objective of the study was to the characterization of the HP33 protein and predict the homo-oligomer models to understand the physical effect of the protein for further research. At first, multiple sequence alignment and sub-cellular localization of the HP33 were predicted by the in-silico approach. The result suggests that this putative protein clustered with another hypothetical protein, Vibrio harveyi, and is an unstable, nonpolar, and outer membrane protein. Functional analysis of the protein by Pfam, InterProScan, and SMART tools predicts that the HP has a single functional domain that may signify a cluster of biosynthetic genes. The prediction of the active site, as well as the protein-protein interaction, were also predicted in this study. Furthermore, a protein-ligand docking investigation revealed two potential therapeutic compounds (Ferroheme C, Valine) that can be effective against HP33 pathogenesis. In conclusion, the homo-oligomers model's predictions and the ab-initio docking findings will offer important information for an additional immunological investigation, which may be beneficial in a future study on SDMND prophylaxis.","PeriodicalId":36569,"journal":{"name":"Genetics of Aquatic Organisms","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48108546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
