【摘要】 2011-2017年对陕西大荔县黄河滩中华鳖国家级水产种质资源保护区鱼类资源开展调查，根据调查区水域分布特点，分别采用三层流刺网、定制流刺网和地笼对保护区进行鱼类资源调查，并结合当地渔民的渔获物收集鱼类样品。本次调查共收集鱼类标本17种，隶属4目7科16属，包括鲤形目11种，鲈形目3种，鲇形目2种以及合鳃鱼目1种。调查结果显示：保护区鱼类物种资源丰富，群落较复杂，鱼类在摄食、繁殖及栖息习性等方面呈现多样化特征。根据鱼类区系复合体学说，保护区鱼类资源主要分为中国江河平原复合体、晚第三纪早期区系复合体以及南方平原区系复合体。更多还原

【Abstract】 An investigation on fish resources in Pelodiscus sinensis National Aquatic Germplasm Reserve of Yellow River Beach was carried out from 2011 to 2017. We used three layers of gill net, custom gill net and ground bamboo cage to collected specimens, and recorded the specimens from local fishermen. The results showed that there were 17 species, belonging to 4 orders, 7 families and 16 genera. There were 11 species of Cypriniforms,3 species of Perciformes, 2 species of Siluriformes and 1 species of Synbranchiformes. Abundant fish species and complex community were found in this reserve, and their habits and lifestyles were highly diverse, including the feeding habits, breeding habits and inhabiting behaviors. These fish fauna of the Pelodiscus sinensis National Aquatic Germplasm Reserve of Yellow River Beach mostly belonged to the following 3 fish-fauna complex: China Plain fish Fauna Complex, Neogene Early Flora fish fauna Complex, and Plan-South fish fauna Complex.更多还原
