摘　　要：运用主成分分析、多变量分析和单因子方差分析方法,对蓬莱、朝鲜近海和日本釜石3个钝吻黄盖鲽Pleuronectes yokohamae群体(78尾)10个分节特征和7个量度特征进行了比较分析。多重比较和单因子方差结果显示,3个群体在2～5个形态特征上均存在显著差异(P=0.05)。采用逐步判别法对形态特征综合分析,利用贡献率大的参数对3个地理群体进行判别分析表明,判别准确率P1为83.3%～100.0%,综合判别率为92.31%。以上分析结果表明,3个群体间存在一定程度的分化,中、日群体间有明显的差异,研究结果可为钝吻黄盖鲽群体遗传学研究提供形态学依据。Ten meristic traits and seven morphological characteristics of marbled sole,Pleuronectes yokohamae （78 individuals）,collected from Penglai,North Korea and Kamaishi populations,were measured and compared by the principal component analysis method,multivariate analysis method and one-way ANOVA. The multivariate analysis and one-way ANOVA results show that there are significant differences （P=0.05） among the three populations in two to five morphological characteristics. Discriminant analysis on the high contributing morphological parameters show that there are extremely significant differences among the three populations of P. yokohamae,with 83.3%～100.0% identification accuracy and 92.31% synthetic identification accuracy. There are significant differences between Chinese population and Japanese population,and a certain extent of geographical variances existed in the three populations.
