1991年4—10月对湖北涨渡湖的底栖动物进行4次定量采样(其中8月进行断面采集),共获底栖动物(寡毛类和水生昆虫)15种,多毛管水蚓、苏氏尾鳃蚓和一种隐摇蚊为优势种。用Iδ指数测定其优势种的分布型式为聚集型。通过分析认为,涨渡湖属于中营养湖。对鱼类的供饵潜力作了初步分析。
From April to October in 1991, four species of zoobenthos were collected from Zhangdu Lake in Hubei Province, of which 15 species were collected from benthos (oligochaeters and aquatic insects) Suillus end gill worms and a species of Cryptocarychus for the dominant species. The distribution type of dominant species was determined by Iδ index. According to the analysis, Zhangdu Lake belongs to Zhongyou Lake. The bait potential of fish was analyzed.
