摘要
论述了二滩库区及相邻江段的鱼类区系组成及其特点 .二滩水库建成蓄水后 ,绝大部分干流和鱼河库区原有江河鱼类区系将发生很大变化 :流水、急流水、浅滩等江河底层和一些下层鱼类将基本消失或消失 ,或呈残存状态 ;静水、缓流水等江河中、上层和一些中、下层鱼类将得到不同程度的发展 .
The faunal composition,characteristics,evolution and development of the Fishes in Ertan Reservois and nearby river area are discussed.It is inferred that the original fish fauna in most main hranches and Ganyu river of the reservoir will greatly change after the reservoir is built and water is reserved.
