To evaluate the seasonal variation of zooplankton community and potential aquaculture impacts, surveys on zooplankton community in mussel farms near Gouqi Island were carried out in October 2022 (autumn), May 2023 (spring), and August 2023 (summer). The results indicated that copepods were the dominant group across three seasons. The zooplankton community structure showed significant seasonal variation (permutational multivariate analysis of variance [PERMANOVA], <i>p</i> = 0.001), with water temperature (WT) and salinity (SAL) identified as the primary environmental drivers by redundancy analysis (RDA). Zooplankton abundance peaked in summer, driven by the dominance of small-sized copepod <i>Paracalanus parvus</i>, while autumn exhibited the highest species diversity. Meanwhile, abundance–biomass comparison (ABC) curves indicated a <i>K</i>-strategist-dominated zooplankton community in spring (<i>W</i> > 0) and a structural shift toward opportunistic <i>r</i>-strategists in summer and autumn (<i>W</i> < 0). Crucially, rather than strictly reflecting anthropogenic disturbance, this zooplankton community miniaturization primarily indicates natural seasonal succession driven by environmental fluctuations. However, we hypothesize that this natural shift may be compounded by top-down grazing pressures from mussels. These findings emphasize the dominance of natural seasonal drivers, with aquaculture activities acting as plausible interacting mechanisms, providing a crucial baseline for future monitoring.</p>","PeriodicalId":8104,"journal":{"name":"Aquaculture Research","volume":"2026 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/are/7401811","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four experimental groups of fish were established: a control group (CK, basal diet), LP37 group (basal diet + 10<sup>9</sup> CFU/g LP37), FF group (basal diet + 20 mg/kg FF), and FF-LP37 group (FF-supplemented diet for 15 days, followed by LP37-supplemented diet for 15 days). Serum, liver, and kidney samples were collected for biochemical and molecular analyses. The FF-LP37 group exhibited the highest weight gain and specific growth rates (SGRs) than those in the CK group (<i>p</i> < 0.05). Antioxidant indices showed that superoxide dismutase (SOD) activity was evaluated in LP37 and FF-LP37 groups; catalase (CAT) activity increased in FF group serum and FF-LP37 group liver (<i>p</i> < 0.05); total antioxidant capacity (T-AOC) was higher in all supplemented groups than in CK (<i>p</i> < 0.05); malondialdehyde (MDA) levels were elevated in the FF group (<i>p</i> < 0.05). Nutritional metabolism-related enzymes (hexokinase [HK], pyruvate kinase [PK], phosphoenolpyruvate carboxykinase [PEPCK], glutamine synthetase (GS), glucokinase, phosphoglucomutase, lipoprotein lipase [LPS], and fatty acid synthase [FAS]) were significantly altered, particularly in LP37 and FF-LP37 groups (<i>p</i> < 0.05). Molecular analysis revealed that expression of interleukin-1 receptor-associated kinase 4 (<i>IRAK-4</i>) and myeloid differentiation primary response 88 (<i>MYD88</i>) in the liver and kidney was upregulated in the FF group (<i>p</i> < 0.05), but downregulated in the LP37 and FF-LP37 groups compared with CK. In conclusion, dietary supplementation with LP37, FF, or the FF-LP37 sequence improved <i>S. schlegelii</i> growth, AOC, immunity, and nutritional metabolism, providing valuable insights for aquaculture dietary strategies.</p>","PeriodicalId":8104,"journal":{"name":"Aquaculture Research","volume":"2026 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/are/5102620","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147667963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
