闽浙近海金色小沙丁鱼种群的初步研究

A PRELIMINARY STUDY ON POPULATION OF GOLDEN SARDINE SARDINELLA AURITA FROM FUJIAN AND ZHEJIANG OFFSHORE WATERS

  • 摘要: 通过对闽南—台湾浅滩渔场,浙江近海渔场金色小沙丁鱼形态计数性状,量度性状特征差异的比较,并结合生物学、产卵场、洄游以及海洋环境条件等综合分析,研究结果表明闽浙近海的金色小沙丁鱼群体分别属于闽南—台湾浅滩地方种群和东海地方种群。本章还讨论了两个海域金色小沙丁鱼的分布。

     

    Abstract: The meristic and morphometric character of Sardinella aurita iscompared between the stocks of Minnan-Taiwan Bank and Zhejiang offshorewaters, combining comprehensive analysis in biology character, spawning ground,migration and marine environment. The results indicated that the stocks of goldensardine in Fujian and Zhejiang offshore waters belong to Minnan-Taiwan Bankpopulation and East China Sea population respectively. The coefficient of variabi-lity (C. V.) of the former is greater than that of the latter. The distribution of twopopulations is discussed as well.
