摘要
东海海区的蓝点马鲛是否为同一种群，通过广泛采集样品——东海北部（３０°３０～３２°３０Ｎ）、东海中部（２８°３０～３０°３０Ｎ）和东海南部（２６°００～２８°３０Ｎ），共１０批，计３９０尾，按三组作形态学测量；经差异系数（Ｃ．Ｄ）、均数差异显著检验和聚类分析等处理，结果表明，分布在东海海区北、中、南部的蓝点马鲛为同一种群。
This paper deals with the population indentification of the spanish mackerel. Samples were collected from northern part ( 30°30～32°30 N ), central part ( 28°30～30°30 N ) and southern part of East China Sea ( 26°00～28°30 N ). 14 morphometrical and meristical characters were observed and measured for being used in the cofficient of difference, comparative analysis of Mdiff and cluster analysis. The results showed that the spanish mackerel above described were all from the same population.
