Abstract: The characteristics and evolution of Taihu Lake aquatic biota were discussed and compared with those of the North American Great Lakes.The results showed that there are 442 species in 146 families in the Taihu aquatic biota as follows: 107 species of fishes in 25 families,accounting for 24.2%;66 species of zoobenthos in 21 families,accounting for 14.9%;103 species of zooplankton in 37 families,accounting for 23.3%;81 species of phytoplankton in 29 families,accounting for 18.3%;and,85 species of aquatic macrophytes in 34 families,accounting for 19.2%.The number of species and families of fishes and zooplankton are slightly higher than those of the other three aquatic organisms.The North America Great Lakes contain 134 species of fishes,165 species of zoobenthos,132 species of zooplankton and 1456 species of phytoplankton.The number of phytoplankton species is higher in the Great Lakes than in Taihu Lake,but otherwise the number of species of the other three types of aquatic organisms in the Great Lakes are roughly equal to Taihu Lake.The dominant species in the Great Lakes are cyprinid and salmonidae,accounting for 18.7% and 20.1%,respectively.The dominant species is cyprinid in four of the five Great Lakes except Lake Erie.The dominant species in Taihu Lake is cyprinid,accounting for 56.1% of the total number of fishes.It is the principle characteristic of Taihu Lake fish fauna and the principle characteristic for Chinese freshwater fish fauna.Therefore,cyprinid is the priority species used in the procedure of water quality criteria derivation.For fishes,zoobenthos and zooplankton,the species numbers are basically equivalent in Taihu Lake and the Great Lakes.
