The combination of fish removal and macrophyte reestablishment is an important way to restore the eutrophic shallow lakes.In order to investigate the effect of this kind of restoration methodson water quality of the subtropical,eutrophic shallow Lake Wuli,Lake Taihu.The water quality of the restored and the un-restored area was monitored from July to December,2010.The results showed that the concentration of TN,TP,Chl a and TSS in the restored area were 43.4%,48.3%,65.5% and 78.9% lower than the un-restored area,respectively.The transparency in the restored area was about three times higher than that of the unrestored area(P<0.05).Based on these results,we conclude that the combination of fish removal and macrophyte reestablishment is an efficient method for restoring subtropical shallow eutrophic lakes,such as Lake Wuli.
