摘　　要：【目的】全面了解云龙水库鱼类资源及净水鱼类群体状况,加强水环境管理。【方法】在库区设置10个采样点,同期分别开展4次采样,对渔获物进行分类鉴定并对样本进行生物学测量和统计分析,利用FiSAT II-VPA进行鲢的资源量估算。【结果】云龙水库库区分布有鱼类16种,隶属3目7科16属。鲢、鳙、鲫、草鱼、麦穗鱼、?、高体鳑鲏、罗非鱼、子陵吻鰕虎鱼、太湖新银鱼、池沼公鱼和棒花鱼为常见种;鲤、泥鳅、大鳞副泥鳅和小黄?鱼为偶见种。麦穗鱼、?、子陵吻鰕虎鱼和太湖新银鱼为优势种;鲤、鲫、鲢、鳙、草鱼、棒花鱼、高体鳑鲏、泥鳅、大鳞副泥鳅、罗非鱼、小黄?鱼和池沼公鱼为非优势种。鲢体质量—体长幂函数关系为:W=1.562 22×10-5L3.024 78 (n=193,R2=0.921 32),资源量估算为5.99×105尾。【结论】云龙水库鱼类资源分布与静水环境条件基本一致,水环境管理中应加大对小型鱼类的捕捞强度及适当投放净水鱼类。[Purpose]To fully understand the fish resources of Yunlong Reservoir and the status of clean water fish groups, strengthen water environment management.[ Method] We set up 10 sampling points in the reservoir area, carried out four samplings at the same time to classify and identify the catches, carried out biology on the samples measurement and statistical analysis, and used FiSAT II-VPA to estimate the resource of Hypophthalmichthys molitrix.[Result]There were 16 species of fish distributed in the Yunlong Reservoir area, belonging to 3 orders, 7 families and 16 genera. H. molitrix, Aristichthys nobilis, Carassius auratus, Ctenopharyngodon idella, Pseudorasbora parva, Hemiculter leucisculus, Rhodeus ocellatus, Oreochromis sp., Rhinogobius giurinus, Neosalanx taihuensis, Hypomesus olidus and Abbotina rivularis were common species;Cyprinus carpio,Misgurnus anguillicaudatus, Paramisgurnus dabryanus and Micropercops swinhonis were rare species. P. parva, H. leucisculus, R. giurinus and N. taihuensis were the dominant species;C. carpio, C.auratus, H. molitrix, A. nobilis, C. idella, A. rivularis, R. ocellatus, M. anguillicaudatus, P. dabryanus, Oreochromis sp., M. swinhonis and H. olidus were non-dominant species. H. molitrix weightbody length power function relationship: W=1.562 22×10-5 L3.024 78(n=193, R2=0.921 32). The resource amount was estimated to be 5.99 × 105 tails.[Conclusions]The distribution of fish resources is basically the same as that of hydrostatic environmental conditions in Yunlong Reservoir. Increase the intensity of fishing for small fish and the proper placement of water-purification fish in water environmental management.
