Abstract:The stock biomass in the open water zone of Taihu lake are dominated by lake anchovy (Coilta ectenes), icefishes, and smaller cyprinids. The stock of structures in community showed a characteristic of small-sized individual, early ripening at low age for longevous species.However the spawning time of Neosalanx taihuensis (a shortlif fish) has been tending to prolong. The fish community of open water zons is belong to a global stability type. Based on the analysis of the past decade catehes in Taihu lake, the stocked exotic species have not disintegration community structure, but the abundace of icefishes is greatly decreased and it's for away from the balance point of stock, because of overfishing in 1994. Therefore the authors suggnsted not to transplant exoticpeies until to the stock returns to mormal condrtron.
Keywords:Taihu lake  Open water zone  Fish community
