| Abstract: | From April to July 2007,a extensive sampling of qualitative and quantitive towards freshwater snails was carried out in Poyang Lake.By sorting,A total of 26 species belonging to 15 genera in 7 families of gastropoda were found.Dominant species are Bellamya aeruginosa,Parafossarulus striatulus and Semisulcospira cancellata.The average biomass and density were 69.60 g/m2 and 110.27ind./m2.Range of Shannon-Wiener index is 1.11~2.11;range of evenness index is 0.76~0.99. |
