Abstract：The shell length (SL) ,shell height (SH) ,shell width (SW) ,hinge length (HL) ,body weight (BW) ,fresh weight (FW) and adductor muscle weight (AMW) were measured and compared in male and female scallop Chlamys f arreri .Multivariates such as correlation analysis ,and path analysis were used to calculate correlation coefficients , path coefficients and determinant coefficient . Regression equation between weight traits and shell traits were established by stepwise regression analysis .The results showed that there were no significant difference between genders in economic important traits ( P> 0 .05 ) . Correlation coefficients between these traits were significant both in male and female populations ( P<0 .01) ,generally higher in females than those in the males .For males ,SL was shown to have the maximal direct effect on BW ,followed by SH .In the females ,SH was shown to have the maximal direct effect while SL gave very slight effect .SH gave the maximal direct effect on FW in female ,followed by SL and SW .For the males ,only SH gave the maximal direct effect .There were different regression equations between weight traits and shell traits between the males and females .
