摘  要：
2009年9月和2010年5月,对北盘江光照水电站影响河段鱼类资源进行现场调查,采集鱼类45种,其中18种为新记录种,各河段鱼类组成特点与生态类型相符。结合相关文献资料,确定调查河段鱼类共71种,其中珍稀濒危鱼类4种,珠江水系特有鱼类3种。光照电站的建设对库区河段的鱼类资源影响显著,喜静缓流生境鱼类占76.5%,喜急流或流水生境鱼类占23.5%;流水生境河段受影响较小,约90%鱼类喜流水生境。调查水域没有典型产漂流性卵鱼类的产卵生境,原记录的产粘性卵鱼类产卵场受影响较小。

摘  要：
A situ investigation was conducted to find out the influence of Guangzhao hydropower station on fish resources in each river section.Forty five fishes were collected and 18 turned out to be newly recorded.It also showed that the fish composition features were in accordance with its ecological type in each river section.Combined with relevant documents,71 different species,were confirmed in those investigated sections,including four rare and endangered fishes,three pearl river special fishes.The impact of Guangzhao hydropower station on the river fish resource was remarkable.Fishes enjoying Slow-flowing environment which was condutive to breeding gradually became dominant species,while fishes preferring fast-flowing water decreased considerably or retreated from the dam river area.In the investigated area,there was no typical breeding environment which was suitable to domestic fishes and other fishes.Little effect was found on the breeding sites for recorded fishes which spawn adhesiveness eggs.A further studu on the effect of fisheries resource proliferation and releasing needs further study.
