大通湖是湖南省最大的养殖湖泊.随着河蚬经济价值的提升,大通湖河蚬Corbicula fluminea（Müller,1774）的开发强度逐年增加.为实现河蚬资源的合理开发,本研究在对大通湖河蚬形态特征、现存量及其时空分布调查分析基础上,重点探讨了养殖和软体动物捕捞对其资源的影响.结果显示,壳长大于6 mm河蚬的平均湿重（BW）、壳长（SL）、壳高（SH）和壳宽（SW）分别为1.41±0.03 g、14.82±0.09 mm、13.73±0.09 mm和9.72±0.06 mm,平均相对高度、圆度和凸度分别为0.930±0.001、0.660±0.001和0.710±0.001.河蚬壳长、壳高、壳宽与湿重的关系分别为:lg BW=-3.45+3.00 lg SL、lg BW=-3.23+2.89 lg SH、lg ...

Lake Datong is the largest lake for aquaculture in Hunan Province, and also one of the typical shallow water lakes in the middle and lower reaches of the Yangtze River. Intensive aquaculture in Lake Datong has been enhanced gradually from 1990s on- ward when fertilization technology in piscieuhure was used. At the same time, the fishing of Corbiculafluminea （ MUller, 1774） in Lake Datong has been increased gradually for these years due to the higher economic benefits. In order to achieve effective conser- vation and proper usage of C. flumine...
