The results showed that a total of 75 fish species were collected, belonging to 5 orders, 16 families, 54 genera. Cypriniformes constitutes the dominant component of species composition, and is consist of 4 families, 39 genera and 51 species, accounting for 68% of the total species, Siluriformes rank is the second including 4 families, 6 genera and 11 species, accounting for 14. 7% of the to-tal species. According to the family of statistics, Cyprinidae consists of 40 species and is the most common species, accounting for 53. 3% of the total species, Bagridae is the second common species, consisting of 7 species, accounted for 9. 3% of the total species. The species composition collected from 4 sections is almost the same, but the main species composition that the ratio of single species of fish to the total catch in weight in this river is greater than 5% are different obviously. The average daily catch of fish for single ship or bamboo rafts in 4 sections is different, the highest is Huiyao section, and the lowest is Lushang section.
