摘 要:青海省是长江、黄河和澜沧江的发源地,地域辽阔,河流密布,湖泊沼泽众多,形成了水生浮游动植物—水生昆虫—鱼类—鸟类—湿地的复合生态共生体系,其中土著鱼类在该生态系统中具有举足轻重的地位。介绍了青海省50种土著鱼类的种类、分布水域、濒危状况,并提出了一些保护建议:设立青海省重要渔业资源禁渔区(包括玛柯河水域常年禁渔区及种质资源保护区;长江通天河段、澜沧江上游常年禁渔区;青海湖、扎陵湖、鄂陵湖、星宿海禁渔区等);利用现有增殖放流设施加大土著鱼类的增殖放流;进一步加强青海省黄河段水利水电工程渔业环境影响评价工作及补偿机制的研究;开展渔业环境监测工作;加强多方合作筹措保护资金。Qinghai province is headstream of Yellow River, Yangtze River and Lancang River. The area of Qinghai province is very wide, and distribute a lot of rivers and lakes. Complex ecosystem is constituted by aquatic plankton, aquatic insects, fish, birds and wet land. And indigenous fish have more important role in the local ecosystem. This article introduced species, distribution and endangered extent of indigenous fish in Qinghai province. Also it provided some measures to protect the indigenous fish. The protection measures included: to set up closed fishing areas of important fishery resources in some areas of Qinghai Province such as Makehe River, Tongtianhe River and Upper Lancang River of Yangtze River, Qinghai Lake, Zhaling Lake, Eling Lake and Xingxiuhai Lake ; to promote the proliferation discharge of indigenous fish with existing facilities ; to further researchon fishery environmental impact assessment and compensation mechanisms of hydropower project in the Yellow River of Qinghai Province; to carry out environmental monitoring of fisheries; to strengthen the protection funds with co-financing.
