| 摘 要： | 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.
