The current situation of fish in Sanhuanpao Wetland was investigated for the first time in this paper. In May( Spring),July( summer),September( autumn) 2016,it was sampled three times for investigation,and based on the investigation data about the fish caught by net45 times in 9 sampling points,the species composition of fish community in the water was analyzed. The results showed that a total of 12 fish species were caught in this investigation,belonging to 4 orders,6 families and 12 genera. There were five fish species for Cyprinidae,accounting for 41. 7% of total species,followed by Cobitidae with three species,accounting for 25% of total species; Siluridae,Esocidae,Eleotridae and Channidae each had 1 species,accounting for 8. 3% of total species. The fish with index of relative importance( IRI) greater than 1000 is the dominant species,and it was calculated that the dominant species were Carassius auratus gibelio,Rhynchocypris percnurus,Misgurnus mohoity,Cobitis taenia Linnaeus,and Perccottus glenii. In this paper,based on the number of individuals,by calculating Margalcf abundance index( D),Shannon-Wiener diversity index( H’) and Pielou evenness index( J’) for the fish in the water,the current situation of fish resources in Sanhuanpao Wetland was analyzed and the corresponding protection recommendations were put forward.
