带鱼(Trichiurrs haumela)在东海的渔获量占全国带鱼渔获量的90%,因而搞清东海区带鱼年渔获量的变化规律,对合理利用东海区的带鱼资源和指导当前该海区近海捕捞生产具有重要的意义。作者根据近几年来的生产实践和有关资料,试对东海区近海带鱼年渔获量的变化与该海区的水文关系,提出一些粗浅的看法。
The catch of Trichiurrs haumela in the East China Sea accounts for 90% of the total catch of the octopus in the country so as to find out the variation of the catch of the octopus in the East China Sea. It is of great significance to make rational use of the octopus resources in the East China Sea and guide the current offshore fishing Production is of great importance. Based on the production practices and relevant data in recent years, the author tries to find some superficial opinions on the change of the annual catch of the offshore sea-borne fish in the East China Sea and the hydrological relationship in the sea area.
