摘　　要：根据《云南鱼类志》记载，云南共有土著淡水鱼类３８２种，居全国各省区之首。在《云南鱼类志》出版后的近１０年间，云南又记载鱼类新种新纪录５０种，相当于国内其它省区自１９８５～１９９７年间发现新种的总和，迄今共记载云南土著鱼类４３２种，占全国淡水鱼类总种数１０２３种的４２．２％，显示云南是我国淡水鱼类多样性最为丰富的省区之一。与此同时，全省大约有１／３的种类日趋减少或濒临绝灭，湖泊鱼类尤为突出，濒危种几乎达到２／３，表明云南鱼类多样性面临严重危机的事实。Yunnan is among the Provinces with the highest species diversity, genetic diversity and ecosystem diversity of freshwater fishes.
