Abstract: Some economic traits of 100 wild mussel Modiolus modiolus samples was individually measured, the samples were random collected from the coast of Dalian. Correlation analysis, collinearity analysis, multiple regression and path analysis were used to investigate the relationship between shell size and body weight in this study. Results showed that all measured traits were significantly correlated with each other (P<0.01). There are no or low levels collinearity among all independent variables. Path analysis shows that, shell length, shell height and shell width had dominant direct effects on body wet weight, body volume and soft-tissue wet weight, in addition, length from front to shell edge also had direct effects on body weight, shell length and shell width had more remarkable direct effects. Shell height and length from umbo to back end had dominant direct effects on dry sofy-tissue weight, adductor wet weight and dry adductor weight, and the length from umbo to back end had more obvious direct effect between them. Optimal regression equations were established by stepwise regression method with shell size traits as independent variables, body volume and body weight as dependant variables. The findings provide theoretical basis for culture and enhancement and selective breeding of M.modiolus.
