%X 采用体长频率法和瞬时生长率法对后湖湖球蚬(Sphaerium lacustre)的周年生产量进行了测算.结果表明,两种方法得到的生产量较为吻合.生产量的带壳湿重和去壳干重分别是:体长频率法,1.048 g/(m2·a), 0.0599 g/(m2·a);瞬时生长率法,1.178 g/(m2·a), 0.0673 g/(m2·a).对应的P/B系数为3.2.,3.4.
%X The production of Sphaerium. lacustre in Lake Houhu was estimated by two methods. The results were:1.048 g/(m2·a) of fresh weight with shell or 0.0599g/(m2·a) of dry weight shell-free by size-frequency method; 1.178 g/(m2·a) of fresh weight with shell or 0.0673 g/(m2·a) of dry weight shell-free by instantaneous growth method. The corresponding P/B ratio were 3.2 3.4, respectively. Thus, the results by the two methods are coincided each other.
