Newly hatched larvae had few osteological elements. Some cranial elements were formed in 4.8 mm notochord length (NL) larvae, including the trabecula cartilage and cartilaginous ethmoid plate. Most osteological elements of the upper and lower jaws, suspensorium and pectoral supports developed in 4.8 mm NL or smaller samples, followed by the opercular, hyoid arch, branchial arch (5.2 mm NL), vertebral column elements and caudal supports (6.4 mm NL) and finally by most of the cranial elements and pelvic supports (9.5 mm NL). Notochord flexion started in 9.5 mm NL larvae. The upper and lower jaws, opercular and pectoral supports were completely ossified first. <em>Siniperca chuatsi</em> larvae possessed a large mouth and sharp teeth, vomer teeth, palatine teeth, and pharyngeal teeth. Active feeding behavior was attributed to the early ossification of the feeding apparatus and the majority of teeth. Ossification of the centrum proceeded in a posterior direction.

In three distinct East Java, Indonesian locations Banyuwangi, Surabaya, and Sampang, primary data was collected via surveys and in-depth interviews. Ordinary Least Square (OLS) regression was employed as estimation technique. The findings indicated that although most fishermen used ice to store their caught fish, not enough ice was used. Fishermen used either very little or no ice at all because they were only fishing for a few hours. Fish buyers also do not want the condition of the fish to be cold because they think that the fish is no longer fresh or was caught yesterday or a few days ago. Regression analysis indicates that the fish quality index (FQI) is positively correlated with environment condition, working hours, work experience, and selling time. Good environmental conditions provide a cleaner fish's storage, reducing contamination and damage. The more time spent fishing and experience involve better handling practices during longer fishing trips, which has a positive impact on fish quality. In contrast, age, gender, fishing group, and temperature have negatively significant on FQI, while there is not enough evidence to support ice usage, storage, and internet access to have impact on FQI. Based on the results, the policy recommendation is to enhancing the awareness and knowledge of fish quality among fish purchasers and fishermen is vital to attain higher-quality fish. The national strategy's current efforts for accelerating stunting prevention could be incorporated with the behavioral change communication approach on fish quality.</div></div>","PeriodicalId":36894,"journal":{"name":"Aquaculture and Fisheries","volume":"10 6","pages":"Pages 1088-1095"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145290103","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}

Understanding the population genetic background is a prerequisite for conservation of black carp genetic resources. Complete mitogenome was analyzed for the first time to study the population genetic diversity and structure of black carp across China. The complete mitochondrial genomes obtained from six wild and three farmed populations ranged from 16,598 to 16,614 base pairs. Black carp populations across China are characterized by moderate to high genetic differentiation (0.08 ≤ <em>F</em>_ST ≤ 0.55, <em>P</em> ＜ 0.05), with a low overall degree of gene flow (0.34 ≤ <em>N</em>_m ≤ 2.61) individuals per generation. The nucleotide diversity (Pi) ranged from 0.0010 to 0.0024 and the average number of pairwise nucleotide differences (<em>K</em>) ranged from 17.4 to 40.2, with the minimum Pi and <em>K</em> values (0.0010 and 17.4) observed in the Foshan population. Compared to farmed populations, wild populations exhibited high average genetic diversity. Neighbor-joining phylogenetic reconstructions revealed two main genetic lineages, one represented by wild populations from the middle reaches of the Yangtze River and the other by populations from the lower reaches of the Yangtze River and farmed populations. The results of Tajima's <em>D</em> and Fu's <em>F</em> neutrality tests and the nucleotide mismatch distribution indicated that wild populations expanded rapidly after undergoing a historic genetic bottleneck. Demographic decline over recent generations has resulted in a bottleneck effect upon black carp populations and genetic connectivity across its distribution has become limited. Poorly designed artificial propagation, long-term inbreeding and random genetic drift probably were the main causes of low genetic diversity in cultured populations.

Sardinella maderensis, predominantly caught by motorized canoes using gill nets and seine nets, is the primary species in these fisheries. To establish management target reference points for the S. maderensis fishery, this study applied the Schaefer production model to aggregated and disaggregated catch and effort data collected by Liberia's National Fisheries and Aquaculture Authority (NaFAA) from 2018 to 2022. The findings indicate that, in both the aggregated and disaggregated models, the current (2022) fishing effort exceeds the MEY level, leading to diminishing economic returns and approaching economic overfishing thresholds. The economic reference points, MEY and E_MEY, were estimated to be 3% and 19% lower in the aggregated model, and 30% and 44% lower in the disaggregated model, compared to the current (2022) catch and relative fishing effort. This situation arises when the cost of fishing exceeds the price of fish, driven by inefficient and ineffective fishing boats, which leads to high unit costs of effort compared to unit revenue. To fully realize the potential of the S. maderensis fishery, this study recommends a combination of input and output control management strategies, the adoption of more efficient fishing technologies, and the provision of alternative livelihoods for coastal communities.</div></div>","PeriodicalId":36894,"journal":{"name":"Aquaculture and Fisheries","volume":"10 6","pages":"Pages 1079-1087"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145290102","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}
