| 摘 要： | 为研究盆地环境条件下幼蟹养殖池塘浮游动物群落结构特征，探究浮游动物群落结构与水环境因子的关系，以促进盆地地区河蟹养殖事业的可持续发展。2021年5—9月，对四川开江民生渔业发展有限公司养殖基地的幼蟹养殖池塘及水源水体的浮游动物群落结构和水环境因子进行采样监测，对采集到的浮游动物进行鉴定和定量分析，并利用生物多样性指数进行水质评价。结果表明，幼蟹养殖期间共发现浮游动物65种（优势种16种），包括轮虫类36种（优势种9种），桡足类15种（优势种2种）和枝角类14种（优势种5种）。幼蟹池塘轮虫、枝角类和桡足类的平均密度分别为1 685.0～25 370.0，1.7～34.3和57.7～960.3 ind·L-1；平均生物量分别为1.087～10.261，0.022～0.434和1.234～13.738 mg·L-1。水源水体轮虫、枝角类和桡足类的平均密度分别为30～510，0～12和2～166 ind·L-1；平均生物量分别为0.001～0.132，0～0.316和0.006～1.081 mg·L-1。幼蟹池塘的Shannon-Weiner多样性指数、Pielou均匀度指数和Margalef丰富度指数变化范围分别为1.233～1.994，0.451～0.678和1.478～2.404；水源水体的变化范围分别为0.849～2.171，0.474～0.910和0.577～2.306。RDA排序结果显示水体T、DO、TP、TN和CODMn是影响浮游动物群落分布的主要因素。生物多样性指数综合评价结果表明，盆地环境条件下幼蟹养殖池塘和水源水体污染状况相同，均处于中污染状态。

| Abstract: | In order to study the characteristics of zooplankton community structure in juvenile crab culture ponds under basin environmental conditions, and to explore the relationship between zooplankton community structure and aquatic environmental factors, so as to promote the sustainable development of mitten crab culture business in the basin area, the zooplankton community structure and water environment factors of the juvenile crab breeding pond and water source body of the aquaculture base of Sichuan Kaijiang Minsheng Fishery Development Co., Ltd.. were sampled and monitored, from May to September 2021, the collected zooplankton were identified and quantitatively analyzed, and the biodiversity index was used for water quality evaluation. The results showed that a total of 65 zooplankton species (16 dominant species) were found during juvenile crab culture, including 36 Rotifera species (9 dominant species), 15 Copepoda species (2 dominant species) and 14 Cladocera species (5 dominant species). The average densities of Rotifera, Cladocera and Copepoda in juvenile crab ponds were 1 685.0-25 370.0, 1.7-34.3 and 57.7-960.3 ind·L-1, respectively; The average biomass was 1.087-10.261, |
