为了深入认识半滑舌鳎形态性状与体质量之间的关系，本研究使用831尾12月龄左右半滑舌鳎个体的体质量[BM（g）]和形态性状，包括全长[TL（cm）]、体高[BH （cm）]、体厚[BW（cm）]，通过模型拟合筛选获得能够反映雌、雄性个体各个形态性状与体质量关系的最佳模型。建立了以形态性状为自变量、体质量作为因变量的回归方程，并计算了直接、间接通径系数和决定系数。模型拟合结果显示，雌、雄个体全长、体高和体厚与体质量的最优拟合模型都为幂函数曲线模型，雌性个体3个形态性状与体质量的最优模型分别为：y⌒＝0．004x3．090、y⌒＝0．382x2．983、y⌒＝61．912x2．461；雄性个体的3个最优模型公式依次为：y⌒＝0．005x3．003、y⌒＝0．300x3．147、y⌒＝57．681x2．156。通径分析结果显示，雌性个体中体高对体质量的直接影响最大，通径系数为0．535，而雄性个体全长对体质量的直接作用最大，通径系数为0．407。雌、雄个体的3 个形态性状对体质量都有极显著的直接作用，其最优多元回归方程：雌性为 BM＝－88．530＋1．297TL＋15．862BH ＋39．021BW；雄性为 BM＝－71．579＋2．587TL＋7．351BH ＋35．595BW。

In order to know the relationship between body mass and morphometric traits in the half smooth tongue sole (Cynoglossus semilaevis ),body mass [BM(g)]and three morphometric traits,e.g.,total length [TL(cm)], body height [BH(cm)]and body width [BW(cm)]of 831 individuals of 12 months old Cynoglossus semilaevis were measured in this study.The best models for female and male individuals reflecting the relationship between each morphometric trait and body mass were obtained through model fitting screening,respectively.We established the regression equation with morphological traits as variables and body mass as the dependent variable and calculat-ed the direct and indirect path coefficient and the coefficient of determination.The results showed that the best⌒model fitted for female individuals was y= 0.004x3.090 for TL-BM,y⌒ = 0.382x2.983 for BH-BM and y⌒ =61.912x2.461 for BW-BM.And for male animals,they were y⌒ = 0.005x3.003 for TL-BM,y⌒ = 0.300x3.147 for BH-⌒BM and y= 57.681x2.156 for BW-BM.Path analysis showed that BH was the most predominant variable to affect BM (0.535)in females,while TL was the largest effect to BM (0.407)in males.Three morphological traits of fe-male and male individuals were all extremely remarkable effects on the body mass.The multiple linear regression model equation were established as BM=-88.530+1.297TL+15.862BH +39.021BW for females,and BM=-71.579+2.587TL+7.351BH +35.595BW for males.
