To ensure the sustainability of the lobster stock, fisheries should be managed properly based on the best available science. In data-limited fisheries, length composition data are most common form information available for researchers and managers since its relatively cheap and simple to collect. In this study, we evaluate the stock status of P. versicolor in Aru Islands waters using three length-based methods: 1) length-converted catch curve (LCCC), 2) length-based spawning potential ratio (LB-SPR) and 3) length-based Bayesian biomass (LBB). The result showed that the mean length at catch of P. versicolor was 80.9 mm in carapace length. Furthermore, the three methods agree that the current status of painted spiny lobster stock seems to be fully exploited where the exploitation rate, the spawning potential ratio, and relative stock size (B/BMSY) were 54%, 35%, and 85%, respectively. Thus, for sustainability of this stock, it is highly recommended to catch P. versicolor at size greater than 80 mm in carapace length.","PeriodicalId":23978,"journal":{"name":"Turkish Journal of Fisheries and Aquatic Sciences","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45483045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The LBB model results indicated that the biomass ratio was above safe biological limits (B<0.5 BMSY) but fishing mortality was slightly higher than natural mortality. Likewise, LBSPR results showed that SL50 for red mullet was higher than its Lm50, while the estimated median SPR was above the limit of 20% set as the biological reference point.

This study focused on the histopathological, oxidative and hematological effects of long-term BPA exposure on wild vimba bream (Vimba vimba) for the first time. Twenty-five fish stocked in each aquarium and exposed to 1000 μg/L BPA for four weeks. Hematological parameters of fish did not differ significantly compared to control group. The antioxidant activity of liver and gill tissues created a significant partial difference between the groups. According to the histopathological studies, intense hyperplasia and necrosis were detected in the gill tissues of the fish exposed BPA. In addition, hypertrophy and epithelial lifting symptom were partly observed. Vocalization and hypertrophic cells was determined in the liver tissues. In conclusions, this study revealed that BPA had an oxidative and especially histopathologically adverse effects on V. vimba, even though it did not have a hematological effect on the treated fish. Although BPA has adverse effects on the health of aquatic organisms, future studies should focus on the residue in fish meat and risk assessment on human health.","PeriodicalId":23978,"journal":{"name":"Turkish Journal of Fisheries and Aquatic Sciences","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45100046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the eco-toxicological effects of waterborne copper oxide nanoparticles (CuO-NPs) having a 32.84nm size and rod shape on a freshwater fish, Labeo rohita. 96-h LC50 of CuO-NPs was 353.98mg/L. Two sub-lethal concentrations equivalent to 1/3rd and 1/5th LC50/96h (70.79 and 117.99 mg/L) of CuO-NPs were selected for 15, 30, and 45-day exposure tests. Bioaccumulation for the 1/3rd 96h LC50 was significantly higher compared to 1/5th of 96-h LC50 of CuO-NPs. There was a sharp decrease in the CAT activity and this decline ultimately increased the TBARS contents. The highest percentage of damaged nuclei and genetic damage index in fish erythrocytes was recorded at the highest concentration and after 45 days of treatment. The adverse effects of CuO-NPs were examined to be dose and duration dependent with increasing extent during all studied time intervals. Summarizing, exposure to sublethal concentrations of CuO-NPs is sufficient to cause alterations in ecotoxicological endpoints such as metal overload, oxidative stress and genotoxicity after chronic exposure.","PeriodicalId":23978,"journal":{"name":"Turkish Journal of Fisheries and Aquatic Sciences","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47304971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite many years of cytogenetic studies, the chromosome complements of many species of gobies remain unknown, and the trends of karyotypic evolution are poorly understood. Here I describe a previously unstudied karyotype of a widespread species from the group of sand gobies (Pomatoschistus marmoratus) and analyze the trends of karyotypic evolution of this group in comparison with other taxonomic groups of gobies from the Atlantic-Mediterranean and Ponto-Caspian regions. For P. marmoratus, the diploid number is 2n=46; it consists of 11 pairs of submetacentric chromosomes, 12 pairs of subtelocentric and telocentric chromosomes (NF=68). A comparative karyological analysis showed that the main trend in the karyotypic evolution of sand gobies differs from that of other groups of gobies and is associated with an increase in the number of chromosomal arms as a result of chromosomal rearrangements leading to a change in the centromere position. The results obtained contribute to understanding the role of chromosomal rearrangements in the evolution of Gobiidae and are of interest for further cytogenetic studies of this large family of fish.","PeriodicalId":23978,"journal":{"name":"Turkish Journal of Fisheries and Aquatic Sciences","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42318865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A high-growth-rate mutant, NyEMS, was recently developed using ethyl methanesulfonate to meet this demand. However, the high-growth-rate mechanisms of NyEMS have not yet been identified because of the poor understanding of N. yezoensis biomolecules. In this study, NyEMS was subjected to comparative transcriptome analysis using RNA-seq. As a result, total of 7,933 differentially expressed unigenes were identified. From the transcriptome analysis, it was demonstrated that increased proteasome expression and repressed 1- aminocyclopropane-l-carboxylate (ACC) production could be responsible for the enhanced growth rate of the mutant. Additionally, genes involved in vitamin B6 biosynthesis were up-regulated, while those related to phycobilisomes were downregulated in the mutant, which could be responsible for its characteristic features. Moreover, 1,281 SNPs and 12,963 cSSRs were identified from assembled data. To determine possible biomarkers, primer pairs were designed from the identified cDNAderived simple sequence repeats.
