调查河段发现有鱼类49种(亚种),没有海河间洄游的鱼类。董箐电站建设将导致长薄鳅、叶结鱼、乌原鲤、长臀鮠、卷口鱼等濒危保护鱼类和珠江水系特有鱼类以及部分经济鱼类减少,甚至绝迹,应予以保护。通过对比分析,建立鱼类增殖保护站,结合资源、环境和渔政的保护管理,合理调度电站的生产运行,可以将电站建设对鱼类资源的影响降到最低的程度。同时,需要进行长期的调查、分析,针对性地采取措施,才能使资源得到长期、有效的利用和保护。
49 species of fish (subspecies) were found in the surveyed river sections, and there was no fish that migrated between the rivers. The construction of Dongtao Hydropower Station will result in the reduction and even extinction of endangered fish species such as long loach, leaf knot fish, wuyuan carp, long-tailed gizzard, and colar fish as well as peculiar fishes of Pearl River water system and some economic fishes and should be protected. Through comparative analysis, the establishment of fish proliferation protection station, combined with the protection of resources, environment and fishery management, and reasonable scheduling of plant production and operation, power plant construction can minimize the impact of fish resources to a certain extent. In the meantime, long-term investigation, analysis and pertinent measures are required to make long-term and effective use and protection of resources.
