We used the Gulf Coast of Florida, where there has been industry and government interest in development, as a case study to explore offshore aquaculture potential and methods for integrating stakeholder concerns into offshore aquaculture development. We assessed (1) social acceptance of offshore aquaculture in the Florida Gulf Coast using public comments; (2) site suitability for offshore development using social, biological, and technical data; and (3) potential impacts of offshore aquaculture on communities using socioeconomic vulnerability indices. We found that many stakeholders distrust policymakers and industry and have concerns about potential environmental impacts. We created species-specific suitability maps for red drum (Sciaenops ocellatus) and almaco jack (Seriola rivoliana), demonstrating that large areas of the Gulf are suitable for offshore aquaculture development. We show that many coastal and fishing-reliant communities have existing vulnerabilities that aquaculture development could affect, but the public comments did not reflect these. To gain social acceptance, industry and government agencies will need to better incorporate public feedback into planning processes in a meaningful way. Consulting local communities and adapting projects in response to their concerns can help to secure social license for offshore aquaculture.","PeriodicalId":17284,"journal":{"name":"Journal of The World Aquaculture Society","volume":"55 1","pages":"40-61"},"PeriodicalIF":2.8,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jwas.13031","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138536864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Growth assessment is particularly important at moderate to high temperatures because of the direct influence of temperature on ectothermic organisms and the increasing trend of warm to extreme environmental temperatures. Therefore, growth, condition factor, and survival of channel (I. punctatus), blue (I. furcatus), and hybrid catfish were compared following a 10-week growth experiment at moderate (23°C) and high (33°C) temperatures in tanks. It was hypothesized that hybrid catfish would outperform channel and blue catfish in overall growth due of heterosis, and growth of all three fish types would be greater at moderate than high temperatures, which are above the range for optimal channel and blue catfish growth. Channel catfish had the greatest growth and were in better condition compared to blue and hybrid catfish over moderate and high temperatures. All treatments had an average survival over 89% other than blue catfish at 33°C, which had an average survival of 63%. Therefore, these results indicate growth and condition factor in channel, blue, and hybrid catfish diminish at high temperatures, and channel catfish may outgrow blue and hybrid catfish at moderate to high temperatures.","PeriodicalId":17284,"journal":{"name":"Journal of The World Aquaculture Society","volume":"55 1","pages":"302-311"},"PeriodicalIF":2.8,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jwas.13038","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135141274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tomato grouper (Cephalopholis sonnerati) is an emerging aquaculture species with a generation cycle of at least 5 to 10 years. Mixed culture of broodstocks and natural mating are commonly employed in hatcheries. To expedite the selection process for tomato grouper, we utilized ISSRseq technology for assisted future growth selection. After 6 months of rearing, we selected 48 individuals, including 24 fast-growing and 24 slow-growing individuals (representing the top and bottom 10% of samples). These samples produced 932 SNPs. Although specific broodstock pairing information is unavailable, our results suggest that these fry likely originated from multiple broodstock exhibiting considerable diversity. Further analysis of genetic relationships among individuals revealed three main clades. One clade contained a higher proportion of faster-growing individuals (80%), while another featured a lower proportion of rapidly growing individuals (28.6%). Through the relatedness network and further exclusion of individuals, the faster-growth clade comprised 92.3% of fast-growing individuals. The faster-growth clade is appropriate for further development into a high-growth strain. Our findings demonstrate that molecular markers can advance population selective breeding to family selection in aquaculture breeding research.","PeriodicalId":17284,"journal":{"name":"Journal of The World Aquaculture Society","volume":"55 2","pages":""},"PeriodicalIF":2.8,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jwas.13035","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135341331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, there were significant increases in dry matter and crude lipid contents in all CAO groups compared with the controls. The mean abundances (%) of the prevalent bacteria at the genus level in the intestinal trout samples presented no significant changes among the test groups. Dietary CAO significantly changed the intestinal histological structure, and was manifested by an increased number of goblet cells in the CAO-supplied groups. However, there were intestinal villus epithelial deformations associated with increasing dietary CAO, and were most prominent in the C28 group. The sensory attributes of cooked trout fillets showed that capsicum's pungent odor and taste was evident in the C14 group and subsequently increased with increasing dietary CAO levels. Accordingly, the results showed, for the first time, that dietary CAO at levels (7–14 g kg−1) can enhance the growth of rainbow trout without negative effects on the sensory characters and gut health.","PeriodicalId":17284,"journal":{"name":"Journal of The World Aquaculture Society","volume":"55 1","pages":"149-168"},"PeriodicalIF":2.8,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jwas.13039","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135678999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In terms of the overall additive-genetic determination, body weight had the greatest impact on abdominal meat weight in both sexes. In contrast, abdominal meat weight, abdominal length, and body weight were most influential on abdominal meat percentage in both sexes. The genetic relationships of growth and morphometrics to meat yield traits were elucidated in M. nipponense for the first time, contributing to formulation of sound improvement plan for the meat yield traits in this commercially important prawn species.","PeriodicalId":17284,"journal":{"name":"Journal of The World Aquaculture Society","volume":"55 2","pages":""},"PeriodicalIF":2.8,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jwas.13036","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135821679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
