温州光唇鱼形态学研究

摘要

项目组将形态度量学和框架结构度量学结合起来，从多维空间去观察温州光唇鱼的外部形态，进行多变量分析。对楠溪江鲤溪段、渠口段、小楠溪段的3个江段的温州光唇鱼形态特征进行了比较研究，发现小楠溪段鱼体体长和体重都明显小于其他2个江段的鱼体，存在显著差异，且鱼体呈异速增长。鲤溪段鱼类尾部更为细长，更适应流水方向迅速的变化，渠口段鱼类最为肥硕。%　　We have a multivariate analysis by combining the methods of framework and morphological measurement to obse-rve the external features of fish with the multi-dimensional space.Aster comparing the specimens which come from Lixi, Qukou and Xiaonanxi, we find that the weight and length of Xiaonanxi's are smaller than of the other two. Furthermore, they grow extremely unusual and rapidly. The tail of fish in Lixi is longer and thinner and can adapt to fast changes of water, while the fish of Qukou are the fattest.
