摘　　要：2008年1-12月对滆湖鱼类进行了调查,对鱼类群落优势种、群落生物多样性相关指数进行了分析,对其繁保区鲢、鳙、鲫的年龄结构进行了调查。共采集鱼类30种,隶属于7目、9科。结果表明,群落优势种为似鳊[Pseudobrama simoni（Bleeker）]、鲫[Carassius auratus（Linnaeus）]、鳙[Aristichthys nobilis（Richardson）]等;多样性特征值平均指标分别为：Margalef指数2.68,Shannon-Wiener指数H′和H″分别为2.02和2.08,Pielou均匀度指数J′和J″分别为0.64和0.66;繁保区鲢、鳙、鲫的年龄结构合理,保护效果良好,但滆湖鱼类在总体上呈现小型化特点;并对渔业管理提出了相关建议。Ichthyological survey in Lake Gehu was carried out from January to December 2008, The analysis of species composition and diversity were also done. Age-structure of Hypophthalmichthys molitrix （ Cuvier et Valenciennes）, Aristichthys nobilis （Richardson） and Carassius auratus （Linnaeus） were investigated in the protected areas. 30 species of fishes belonging to 7 orders, 9 families were collected and identified. The results indicated that the dominant species were Pseudobrama sirnoni （Bleeker）, Carassius auratus （Linnaeus）, Aristichthys nobilis （Richardson） , et al. Average characters of biodiversity indicated that Margalef＇s index was 2.68, Shannon-Weiner diversity index H＇ and H＂were 2.02 and 2.08, Pielou＇s index J＇and J＂ were 2.02 and 2.08. The fishery community in Lake Gehu took on character of miniaturization. Age-structure of Hypophthalmichthys molitrix （ Cuvier et Valenciennes） , Aristichthys nobilis （Richardson） and Carassius auratus （Linnaeus） were reasonable. The protection effect was good. Finally, the fishery strategy for the lake has been put forward in view of the above results.
