| 摘 要： | 对2005年-2010年采自渤海、黄海和东海海域的9个小黄鱼（Larimichthys polyactis）群体共208个个体进行了形态学比较研究，运用主成分分析、判别分析、聚类分析和单因子方差分析等多元统计分析方法对9个小黄鱼地理群体的20个量度特征和8个分节特征进行分析。结果显示，判别分析的综合判别率为73．6％。其中东海（宁波）群体判别率最高（86．4％）；黄海SY4群体判别率最低（54．3％）。主成分分析、聚类分析和单因子方差分析结果一致，均显示渤海群体与黄海、东海群体间存在一定程度的分化。

| Abstract: | To compare the morphological differences among 9 small yellow croaker （ Larimichthys polyactis） populations, we analyzed 20 morphological characteristics and 8 meristic counts of 208 individuals collected from Bohai Sea, Yellow Sea and East China Sea during 2005 -2010 by using multivariate statistical analysis （principal component analysis, discriminant analysis, cluster analysis and One-Way ANOVA）. The results show that the total accuracy of discrimination for the 9 populations is 73.6%, with the highest 86. 4% in Ningbo and the lowest 54. 3% in SY4. The results of principal component analysis, cluster analysis and One-Way ANOVA are consistent, which indicates that geographical variance exists between Bohai Sea population and other populations from Yellow Sea and East China Sea. |
