摘　　要：通过对乌江中游右岸支流石阡河上游、下游鱼类的实地调查,研究了石阡河鱼类物种的多样性。结果表明,石阡河共分布有鱼类32种和亚种,分属3目9科28属。其中以鲤形目鱼类最多,有23种和亚种,占总种数的71.9 %。厚唇光唇鱼为乌江水系鱼类新记录。宽鳍、马口鱼、泸溪直口鲮、宽口光唇鱼、大鳍鳠、切尾拟鲿、福建纹胸等鱼类为目前石阡河中的优势种。石阡河与乌江中游干流之间存在着鱼类物种组成上的差异。石阡河与邻近的沅江上游支流锦江和阳河之间可能存在着鱼类物种分布上的交流。The species diversity of fish in the Shiqian River is surveyed and studied. The result shows that a total of 32 species or subspecies of fish in 28 genera in 9 families, 3 orders are distributed in the river. The species Acrossocheilus labiatus is found in the Wu River system for the first time. The species Zacco platypus, Opsariichthys bidens, Rectoris luxiensis, (Acrossocheilus) (monticolus), Mystus macropterus, Pseudobagrus truncates and Glyptothorax fukiensis are the current dominant (species) in the Shiqian River. The species diversity of fish in the Shiqian River is different from that in the middle Wu River. Some tributaries of the Shiqian River probably are connected with those of the Jin River and (or) the Wuyang River both of which belong to the Yuan River system.
