The Chishui River is an important part of the Rare and Endemic Fishes Nature Reserve in the upper reaches of the Yangtze River. We surveyed the Chishui River between April and October of 2007 to assess the current status of fish assemblages it contains. We sampled 51 sites in the river basin and identified a total of 119 species belonging to 5 orders, 16 families and 75 genera. Among them, 25 species were new records for the Chishui River basin and 34 species were endemic to the upper reaches of the Yangtze River. Sinocrossocheilus labiatus was present only in the Chishui River. There were 36, 61 and 100 fish species found in the upper, middle and lower reaches of the river, respectively. Zacco platypus, Spinibarbus sinensis, Pelteobagrus nitidus, Hemiculter tchangi and Saurogobio dabryi were the main commercially-important species captured of the Chishui River, but the components of fishery catches varied significantly among reaches. We offer recommendations for the protection of the diminishing fish resources of the Chishui River.
