摘要
洋圻湖现有鱼类３３种，隶属于５目１２科。其中鲤科鱼类为该湖的主要鱼类，种数占该湖鱼类总数的５７５７％。该湖中白鲢体长与鳞径呈直线关系，体长与体重呈幂函数关系，可用ＶｏｎＢｅｒｔａｌａｎｆｙ生长方程描述其生长规律。
There were 33 fish species survived in Yangqi Lake, which belong to 12 families of 5 orders. Most fish in the lake are Cyprinidae, which account for 57.57%. The body length and the scale diameter of silver carp were lineary correlated, while the fish body length and the body weight were exponentialy correlated. The growth of the fish could be expressed by Von Bertalanffy's growth equation.
