| Abstract: | By investigationg the benthon inhabited in the eastern Taihu lake and its pen fishfarming area, we analysed prelimilarily their composition, abundance, biomass and diversity as well as their distribution. Selecting the three bio-quantity indexes, i. e., the Goodnight Index, the King and Ball Index and the Density of Tubificidae, we give a primary assessment and division of the environment quality in the pen fishfarming area. The necessity has been expounded that we should carry out properly and control pen fishfarming. The first advice has been put forward that is how to control the pollution caused by pen fishfarming. |
