摘    要:随机选取1176尾浅色黄姑鱼其中有600尾雌性和576尾雄性研究其形态性状对其体重的影响,测定性状包括其体长(X1)、躯干长(X2)、尾长(X3)、头长(X4)、体高(X5)、最大体周(X6)、体重(Y)。利用相关分析方法计算各性状间的相关系数,并通过通径分析方法计算其以体重为依变量各形态性状为自变量的通经系数和决定系数。结果表明:雌雄性浅色黄姑鱼各形态性状与体重之间相关性均达到极显著水平(P<0.01);雌性浅色黄姑鱼中各形态性状中体长、最大体周、体高、尾长、躯干长的通径系数达到极显著水平(P<0.01),而雄性浅色黄姑鱼各形态性状中体长、最大体周、头长、尾长、躯干长的通径系数达到极显著水平(P<0.01);决定系数分析结果表明雌性浅色黄姑鱼的体长和最大体周对其体重的决定程度最大;而雄性浅色黄姑鱼最大体周和躯干长对其体重的决定程度最大。经多元回归分析去除偏回归系数不显著的性状,建立多元回归方程。

关 键 词:浅色黄姑鱼  形态性状  体重  相关分析  通经分析  多元回归方程

Abstract:In order to study the effects of morphometric characters on the body weight in Nibea coibor,1176 individuals were randomly sampled including 600 female and 576 male.The attributes measured in this study include body length(X1),trunk length(X2),caudal(X3),head length(X4),body high(X5),maximum body circumference(X6),and body weight(Y).The correlation coefficients between every two metric traits were constructed by correlation analysis.The paths and determination coefficients in which the body lengths were used as the dependent variable and other attributes were used as independent variables were calculated by path analysis.The results showed that the correlation coefficients of each morphological trait to body weight were all at extremely significant level(P<0.01) in female and male Nibea coibor.The path coefficients of body length,maximum body circumference,body high,caudal length and trunk lengths to body weight all reach at extremely significant level(P<0.01) in female Nibea coibor and the path coefficients of body lengths,maximum body circumference,head length,caudal length and trunk length to body weight all reach at extremely significant level(P<0.01) in male Nibea coibor.The analysis results of determination coefficients show that the body length and maximum body circumference are the most important determination morphological traits to body weight in female Nibea coibor,the maximum body circumference and trunk length are the most important determination morphological traits to body weight in male Nibea coibor.The multiple regression equation was established by multiple analyses after eliminated the morphological traits on body weight which are not significant.
Keywords:Nibea coibor  morphological trait  body weight  correlation analysis  path analysis  multiple regression equation
