Among them, Limnodrilus claparedianus and Pelopia gr. punctipennis were dominant. The mean density of zoobcnthos in the lake was 2087 ind./m2, while the mean biomass 4.869g/m2. A comparison was made between the zoobcnthos of Caogang Lake and those in the shallow lakes along the middle rcachcs of the Changjiang River. |
