| Abstract: | Using the method of principal components analysis,a new coeffcient is summed up from the six variables which are body length,body weight,ovary weight,maturation coeffcient,absolute breed amount and relative breed amount,and these variables are closely related to Acipenser sinensis cray fecundity.According to the new coefficient,19 samples Acipenser sinensis cray fecundity are putted in order,and these samples can be devided into 5 types. |
