| 摘 要： | 利用9个耳石形状指标对我国鱚属鱼类少鳞鱚、多鳞鱚及斑鱚共78个个体的矢耳石形态进行了多元统计分析,同时对3个群体的74个少鳞鱚矢耳石形态进行了判别分析。单因子方差分析结果显示,少鳞鱚与多鳞鱚矢耳石的9个形状指标均存在显著差异(P<0.05);反映耳石长、短轴差异程度的第1主成分与反映耳石三维特征的第2主成分解释了85.943%的形态差异;9个指标在种间判别分析中的综合判别正确率为93.6%,种内判别分析中的综合判别正确率为93.2%。研究表明形状指标法可以作为中国鱚属鱼类鉴别的有效手段。

| Abstract: | Multivariate statistical analysis was conducted for 9 sagittae's shape indices of 78 individuals of Chinese Sillago fishes,namely,Sillago japonica,S.maculate,and S.sihama,discriminant analysis was also conducted for 74 individuals of S.japonica from 3 different stocks.Significant differences were found between S.japonica and S.sihama in their 9 otolith shape indices by one-way analysis of variance (P<0.05).The first two principal components which reflect the difference between major axis and minor axis alon... |
