| 摘 要： | 本文研究了台湾海峡南部和北部的金色小沙丁鱼当年生幼鱼计数性状和量度性状特征差异,并结合其生物学特性、产卵场、洄游及海区环境特征进行综合分析。结果表明,台湾海峡南部和北部的索饵幼鱼仍属于同一地方种群:闽南-台湾浅滩语地方种群。根据其索饵洄游特点,可分为台湾海峡南部和北部两个索饵群体.

| Abstract: | The meristic and morphometric characters of Sardinella aurita are compared by counting and mearsured between the stocks in the south and the north of the Taiwan Strait, respectively, by taking into account of the comprehensive analysis in biology characters, spawing ground,migration and environmental conditions. These are no difference in meristic characters. They belong to the same local population, the Minnan-Taiwan Shoal local population. Basing upon the feeding migration, they belong to feeding stock (or ecological groups) of Southern Taiwan Strait and that of Northern Taiwan Strait. The Southern Taiwan Strait feeding stock is influenced by much complicated environmental conditions. Thus its coefficient of variability (C. V.) is greater than that of Northern Taiwan Strait feeding stock in the mean values of various meristic characters. |
