摘　　要：为了解岱衢洋海域游泳动物资源及其群落稳定性特征,根据2023年10月(秋)和2024年4月(春)对岱衢洋海域两个航次的渔业资源调查资料,运用ABC曲线法和聚类分析对游泳动物群落结构进行分析,并构建了鱼类和甲壳类生物量粒径谱,比较分析了春、秋季节两个群落生物量粒径谱的特征参数差异性。结果显示,鱼类种类数减少,甲壳类种类增加;春季鱼类、甲壳类Sheldon型生物量粒径谱均呈现不规则锯齿状,秋季鱼类、甲壳类生物量粒径谱呈现“M”形;春季标准化生物量粒径谱鱼类曲率大于秋季,曲线较平缓,受干扰程度较小;春、秋季甲壳类群落结构较稳定。研究表明,岱衢洋海域鱼类群落、甲壳类群落均以小型个体为主,缺少大粒径游泳动物,能量传递效率较低,后期还需对岱衢洋海域加强养护管理。To understand the nektons resources and community stability characteristics in the Daiquyang sea area,based on the fishery resources survey data from two cruises in October(autumn)2023 and April(spring)2024 in the Daiquyang sea area,the ABC curve method and clustering analysis were used to analyze the community structure of nektons,and the fish biomass size spectrum and crustacean biomass size spectrum were constructed.The differences in the characteristic parameters of the spring and autumn community biomass size spectra were compared and analyzed.The results show that the number of fish species decreased,while the number of crustacean species increased;the Sheldon-type biomass size spectrum of fish and crustaceans in the spring showed irregular sawtooth shape,while the biomass size spectrum of fish and crustaceans in the autumn showed“M”shape;the curvature of the standardized biomass size spectrum of fish in the spring was greater than that in the autumn,and the curve was relatively flat,indicating less disturbance;the community structure of crustaceans in the spring and autumn was relatively stable.The study shows that the fish community and crustacean community in the Daiquyang sea area are mainly composed of small individuals,with a lack of large-sized nektons,and the energy transmission efficiency is low.Further management and protection of the Daiquyang sea area is needed in the future.
