They offer the advantage of eliminating confounding factors that might appear in whole-organism studies (e.g., history of prior exposure, sex, age), allowing for tight control over conditions during an experiment, and reducing the number of animals used, thereby suppressing ethical concerns. Cell lines offer the potential for examination of targeted cellular and molecular processes of stress reactions, e.g., gene expression, protein biosynthesis, and signal transduction pathways. They are reproducible and efficient and thus can be used in high-throughput screening and comparison analysis. The value of cell lines in the assessment of impacts of different environmental stressors on aquatic animals is addressed in this review. We outline the methodology used, key findings relevant to ESR genes and function, and implications of the research on adaptation, identification of biomarkers of stress, conservation, and environmental protection strategy development.

The adoption of sustainable practices, such as Aquamimicry Shrimp Farming (ASF), is crucial for mitigating environmental impacts while enhancing food security. Aquamimicry applies biomimicry principles to replicate natural aquatic ecosystems within closed farming environments, thereby promoting effective waste management and optimizing shrimp production. This study assessed the carbon footprint (CF) of ASF operations in Prachuap Khiri Khan Province, Thailand, using a Life Cycle Assessment (LCA) framework combined with statistical techniques, including descriptive statistics, multivariate analysis, and stepwise regression, to evaluate different production levels. Data were collected from 40 shrimp farms practicing ASF under Good Agricultural Practices (GAP) certification scheme. Farms were classified into three groups based on yield: Group H (high production, over 10 tons/ha), Group M (medium production, 5–10 tons/ha), and Group L (low production, ≤ 5 tons/ha), to investigate the association between farming practices and carbon emissions. Results indicated that improved management practices were positively associated with increased productivity and lower carbon footprints, with Group H exhibiting the most favourable sustainability indicators. Electricity consumption emerged as the primary contributor to total carbon emissions (51.35%), while the rearing phase accounted for the majority of emissions (88.05%). A negative correlation was observed between carbon footprint and shrimp survival rates (r = -0.357), underscoring the importance of efficient farming strategies. Stepwise regression identified average harvest size and stocking density as significant factors influencing production outcomes. Well-managed farms in Group H achieved better feed conversion ratios, higher survival rates, and lower emissions per unit of shrimp produced. In conclusion, the findings highlight that effective management within Aquamimicry systems enhances both production efficiency and environmental sustainability, reinforcing the potential of ASF as a promising strategy for sustainable shrimp farming.</p></div>","PeriodicalId":8122,"journal":{"name":"Aquaculture International","volume":"33 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During chronic cold exposure, WD demonstrated: 1. Superior survival duration and CDD relative to all groups (<i>P</i> &lt; 0.05). 2. 11.5% MPH with 12.9%/10.0% SPH over WW/DL. The cold tolerance of the four populations ranked as: WD &gt; DW ≥ DD ≥ WW. Notably, DW hybrids displayed negative heat heterosis (-2.3% MPH) but marginal cold heterosis (3.8% MPH). These findings identify WD hybrids as promising germplasm for breeding temperature-resilient sea urchin strains, with specific heterosis patterns suggesting maternal effects in thermal adaptation.</p></div>","PeriodicalId":8122,"journal":{"name":"Aquaculture International","volume":"33 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
