%X In May-June and September-October 2010, an investigation of commercial fishing was carried out in the Chishui River. Based on the fishery statistic data, total fish catch was estimated. The length-structure VPA method was applied to evaluate the stock size of Acrossocheilus yunanensis, Mystus macropterus and Hemiculter tchangi. The results showed that the biomass of the above three species was 1.23 tones, 2.61 tones and 2.35 tones, respectively. The total fish biomass for reaches of Chishui Town, Chishui City and Hejiang County was 10.76 tones, 51.05 tones and 71.37 tones, respectively.
