| 摘 要： | 运用3种多元分析方法，对黄唇鱼Bahaba flavolabiata、大黄鱼Pseudosciaena crocea、丁氏鱼或Wak tingi和棘头梅童鱼Collichthys lucidus 4种鱼的21个形态性状的种间形态差异进行了定量比较研究。结果表明：4种鱼的所有性状差异显著（P〈0．01），头部性状以及臀鳍条数、脊椎骨数、幽门盲囊数是区别4种鱼的主要性状，黄唇鱼与丁氏馘、大黄鱼、棘头梅童鱼的差异逐渐增大；大黄鱼与黄唇鱼、丁氏馘的差异相当，而大黄鱼和棘头梅童鱼形态差异较小。以逐步判别分析方法建立了4种石首鱼的判别函数，判别准确率分别为98．31％～100％（P1）和98．36％～100％（P2），综合判别率为99．46％。

| Abstract: | Three multivariate morphometrics were used to investigate the morphological variations in 4 fish species Chinese bahaba Bahaba flavolabiata,large yellow croaker Pseudosciaena crocea,Ting's wak Wak tingi and spiny head croaker Collichthys lucidus.ANOVA indicated that four species showed significant morphological variations(P< 0.01).The principal component analysis and cluster analysis revealed that the large yellow croaker and spinyhead croaker had similar morphological characters and much more differences f... |
