黄海南部和东海的日本鲐鱼和蓝圆鲹以浮游动物为主食,并兼食鯷鱼等小型鱼类。因此浮游动物的分布及其季节变化同鲐、鲹渔场的关系密切。本文报导了1972—1975年间,对黄海南部和东海浮游生物组成和数量分布的调查结果,并据此对鲐、鲹渔场的位置、渔期、渔获量以及洄游路线等进行了分析研究。不同季节,鲐鲹鱼类的产卵群、索饵群和越冬群形成的渔场位置及其变迁,都和浮动动物的分布、数量变化有密切的关系。
The Japanese anchovies and blue fishes in the southern Yellow Sea and the East China Sea are dominated by zooplankton and eat small fish such as anchovy. Therefore, the distribution of zooplankton and its seasonal changes are the same, the fisheries are closely related. This paper reports the results of the survey of the distribution and distribution of plankton in southern and eastern Yellow Sea during 1972-1975. Based on the results, the location, fishing season, catch and migratory route of 鲐 and 鲹 fisheries were analyzed. In different seasons, the locations and changes of the fisheries formed by the spawning, feeding and overwintering groups of the catfish are closely related to the distribution and quantity of the floating animals.
