摘要
本文用浙江省海洋水产研究所收集测定的带鱼渔捞统计及生物学资料,研究带鱼亲体与补充量关系,得出关系式为R=9.7542 Ae-0.1477A。从而求得最大持续产量所需的亲体量为5.3亿尾。而1986年的亲体量仅为4.6亿尾。确认带鱼产卵亲体已严重不足,亟需加强管理。
This paper deals with the relation between adult stock and fecruitment of hairtails population in the East China Sea as determined through biological information and computation of the catches. The relation can be expressed by the formula R=9.7542Ae^(0.1477A). The number of adult stock of hairtails needs to be 530 million for the maximu continuous catch; in 1986 it was only 460 million. The winter copcludes that there is a serious deficiency in the number of spawners of hairtails population in the East China Sea, and improved management in resources is urgently needed.
