As a euryhaline species, <em>Penaeus vannamei</em> is temperature-sensitive, with its temperature adaptation mechanisms under varying salinities and temperature-salinity effects in complex environments remaining unclear. This study investigated the adaptability of <em>P. vannamei</em> to thermal stress under two salinity conditions (30 ‰ and 2 ‰). Results showed low salinity was less conducive to high-temperature adaptation, with heat stress decreasing low-salinity shrimp survival by 15.83 %. It also induced fluctuations in oxidative stress markers (SOD, MDA, ROMO1, and HSP90), osmotic regulation indicators (NKA-α, NKA-β, CLC, and CA), and digestive enzymes (AMS and chymotrypsin) under both salinity conditions. Moreover, due to temperature-salinity interaction, heat stress more readily induces physiological dysfunction and tissue damage in low-salinity shrimp, with 47 % reduced intestinal villus height. Furthermore, temperature and salinity interacted, with thermal stress more likely to cause physiological dysfunction and tissue damage in shrimp maintained at low salinity. Metabolomic analysis revealed that thermal stress induced changes in hepatopancreatic metabolic phenotypes at different salinities, with enriched differential pathways primarily related to amino acid and lipid metabolism. A total of 18 biomarker metabolites were identified. Additionally, thermal stress altered the richness, diversity, and composition of the intestinal microbiota, leading to the identification of 19 genus-level microbial markers. A correlation was observed between hepatopancreatic metabolites and intestinal microbiota composition. The study further identified a correlation between hepatopancreatic metabolites and intestinal flora composition. Our results indicate that low salinity may exacerbate high-temperature adverse effects on shrimp by impacting digestion, energy metabolism, oxidative stress, and intestinal physical-biological barriers.</div></div>","PeriodicalId":8375,"journal":{"name":"Aquaculture","volume":"612 ","pages":"Article 743188"},"PeriodicalIF":3.9,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145154379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As domestication modifies these traits, aquaculture potential is expected to evolve over generations, influenced by breeding strategies. However, little is known about how different management approaches may shape this evolution during early domestication. In this study, we tracked changes in aquaculture potential over four captive generations of wild-caught zebrafish (<em>Danio rerio</em>), subjected to three breeding strategies: no selection (NS), single-function selective breeding program (S-SBP; growth-related traits), and multi-function selective breeding program (M-SBP: growth, reproduction, welfare). S-SBP and M-SBP employed within-family selection based on a phenotypic index. We developed a standardized Aquaculture Potential Score (APS) integrating growth (standard length, height/length ratio, specific growth rate), reproductive (fecundity, sperm motility), and welfare traits (stress-induced cortisol, Fulton's condition factor). Trait evolution was assessed using linear model predictions and genetic trends based on estimated breeding values and heritability derived from pedigrees. Selective breeding (S-SBP and M-SBP) rapidly improved growth and morphometric traits, whereas NS lines showed minimal change. Reproductive and welfare traits, however, remained largely static due to both low heritability (h² &lt; 0.20) and environmental modulation. Consequently, APS remained stable across generations, with growth gains offset by stagnation in other domains. These findings underscore that (i) early selection may effectively improve high-heritability traits; (ii) composite metrics like APS may obscure divergent trait responses.</div></div>","PeriodicalId":8375,"journal":{"name":"Aquaculture","volume":"612 ","pages":"Article 743194"},"PeriodicalIF":3.9,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145154946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Crabs were fed isonitrogenous and isolipidic diets containing 0 (control), 300 or 600 mg/kg salidroside (S300 or S600), 300 or 600 mg/kg astragalus polysaccharides (A300 or A600) for 8 weeks. After feeding trial, each group underwent a 24-h hypoxia stress with dissolved oxygen maintained at 2.0 ± 0.2 mg/L. The weight gain of A600 group has significantly increased. Hypoxia significantly reduced the oxygen consumption rate and hemocyanin content. In contrast, S300 group exhibited a significant increase in hemocyanin content, whereas A600 group showed a significant decrease in oxygen consumption rate. S300 group showed significant increases in glycogen content and <em>cpt1</em> expression, whereas lactic acid and triglyceride contents significantly decreased. Supplementation with 600 mg/kg astragalus polysaccharides reduced glycogen and triglyceride contents at different oxygen levels. Salidroside significantly reduced malondialdehyde content, it also increased glutathione peroxidase and superoxide dismutase activities. Under hypoxia, only A600 group increased alkaline and acid phosphatase activities compared to the control group. Thus, salidroside and astragalus polysaccharides effectively increased hypoxia tolerance by reducing the oxygen consumption rate, improving energy metabolism, strengthening antioxidant capacity and regulating immune responses. Based on these findings, dietary supplementation with 300 mg/kg salidroside or 600 mg/kg astragalus polysaccharides is recommended to improve crab growth performance and hypoxia tolerance.</div></div>","PeriodicalId":8375,"journal":{"name":"Aquaculture","volume":"612 ","pages":"Article 743216"},"PeriodicalIF":3.9,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145109390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 addresses this gap by examining the relationship between knowledge management and innovation capability in shrimp farms in the province of El Oro, Ecuador, a relevant industry to the local economy and global exports. The methodology involved a partial least squares analysis of data collected from 186 shrimp producers. Data collection was conducted using convenience sampling, given the sensitivity of sharing business information. The results show a positive and statistically significant relationship between knowledge management practices and innovation capability, with a path coefficient of 0.423 and 32 % of the variance explained in the innovation capability by the knowledge management variable. The study provides valuable insights for industry stakeholders, including policymakers, researchers and entrepreneurs in the shrimp sector, seeking to drive sustainable growth in the aquaculture sector. The findings highlight the need to continue investing in knowledge management practices to maintain and enhance shrimp companies' innovation capability, thus ensuring their long-term viability in the global market.
