| 摘 要： | 通过鄱阳湖对南矶山自然保护区鱼类的采样和调查，记录鱼类58种，分别隶属于6目14科43属。其中鲤科鱼类37种，占总数的63.79%，其余各科共21种，占总数的36.21%。与以往记录相比，保护区鱼类群落结构以及鱼类个体均小型化。此外，统计了主要鱼类的平均体重、生物量和K值,并探讨了鱼类资源衰竭和个体小型化的原因和保护对策。 较准确地反映了现阶段鄱阳湖西南水域渔业资源的特点和现状。

| Abstract: | Fish resources in Nanjishan natural reserve were investigated from 2003 to 2004. A total of 58 species belonging to 6 orders, 14 families and 43 genus were found. Within the fishes, there are 37 cyprinoid fish, accounting for 63.79% of the total, and 21 species of other families 36.21% of total. The community structure and the fish individuals become smaller in the natural reserve. The average weight, growth index K and biomass of the main fishes were measured and the reasons for the smaller size and the measures for protection and propagation were analyzed. The purpose of the investigation is to understand the present status of the fish resources in Poyang lake watershed. |
