| 摘 要： | 采用形态度量与框架度量相结合方法测量了13个地理区域的宽鳍鳃标本,并进行了主成分分析。结果表明:宽鳍鳃的形态变异主要表现在躯体纵轴及头部特征上。头部的形态变异大于躯体的形态变异。宽鳍鳃的分布没有明显的地理位置方面的南北和东西变化特点,各地理区域的宽鳍鳃应视为一个种。

| Abstract: | In the present paper, specimens of Zacco platypus (Temminck et Schlegel) collected from 13 areas were researched by the methed of the frame and morphomentric and principle component analysis was conducted. The result showed that main morphological differences for the Zacco platypus were expressed on the longitudinal axial and the head. The morphological variations on the head were stronger than that on the the longitudinal axial. No significant difference was observed in the localities to north-south or east-west for the fishes. The Zacco platypus from the localities was regarded as one species. |
