洮儿河是内蒙古最重要的淡水渔业基地之一，也是一个具有特色的复合生态系统，近年来该流域的渔业产量锐减，野生鱼类逐渐减少。为保护该流域的生物多样性及全面了解鱼类资源的自然和经济特性，于2011年-2012年利用渔获物、刺网和地笼采捕的方法并结合市场调查，对洮儿河流域进行了鱼类资源调查，共采集到洮儿河鱼类的种和亚种共74种，分属于8目16科，其中鲤科46种，占62．2％。区系组成分归6个区系类群，其中属于江河平原区系复合体鱼类26种，占35．1％；该河具有北方山地区系复合体和北极淡水区系复合体鱼类，显示了该河鱼类的特殊性。提出相应的保护措施，为该河流域保护生物多样性的宏观决策及进行合理渔业提供科学依据。

In recent years,the decreasing of wild fishes causes the dropping of fishery production in Tao er river which is one of important freshwater fishery bases and has a special compound ecosystem. To protect the biodiversity and clearly know the natural and economical characteristic of fish resources in Tao er river, the fish resources were investigated by analyzing the fish catches (use a gill net and ground cage) and investigating the fish market from 2011 to 2012. The 74 species and subspecies fish samples were collected and classtified into 8 orders and families, including 46 species of the family Cyprinidae, accounting for 62.2% ; The fish faunal was divided into six groups with two special faunals : north mountain and Arctic freshwater, including 26 complex fishes of the river plain faunal, accounting for 35.1%. At the same time the relative protection measures were put forward to provide scientific basis for macro policy management of biodiversity protection and reasonable fishery.
