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> &gt; 0) and a structural shift toward opportunistic <i>r</i>-strategists in summer and autumn (<i>W</i> &lt; 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}

But further, the paper introduces the potential of commercial aquaculture in supporting the cultivation of species of conservation interest alongside traditional commercial species (aquaculture-assisted ecological restoration).

Molecular detection depends on reliable and cost-effective sample collection. Recent studies have demonstrated the potential for utilising naturally occurring filter-feeding animals as a mechanism for collecting DNA from the environment (i.e., ‘natural samplers’) for use in downstream molecular assays. This opens the possibility of sampling with minimal training or expertise, offering the potential to easily integrate this sampling within normal farm operations.
