摘要
本文根据１９９１—１９９３年《浙江渔场鲐鲹鱼资源利用研究》课题要求，综合分析了夏秋季渔场的水文特征，浮游动物的种类组成及数量分布，鲐鲹鱼不同群体的分布及生物学特征，幼鱼发生量的历年变化，围、拖网捕捞鲐鲹鱼的现状。讨论了海况环境对鲐鲹鱼渔场形成的制约作用，阐明鲐鲹鱼中心渔场的形成与水文环境和浮游动物量的关系，分析了鲐鲹鱼的资源状况及利用潜力，提出进一步开发利用的建议。
To fulfill the project of 'The Stock Utilization Survey of Mackerel and Scad in Zhejiang Fishing Area' during 1991 1993, the paper synthesized the hydrologic characteristics, the apecies composition and the quantitative distribution of zooplankton in fishing areas in summer and autumn,the distribution and biological characteristics of different mackerel and scad colonies, the yearly variation of the emergence size of juvenile fishes and the current fishing state of mackerel and scad caught by purse seine and trawi, discussed the effects on fishing area forming of environment, elucidated the relationship among the central fishing area forming of mackerel and scad,hydrologic environment and zooplankton's biomass, analysised the stock situation and exploiting potentiality of mackerel and scad, and made some proposals for expioitation andutilization .
