福建近海渔业资源结构及其主要种群生态的变化

Change in Structure of the Fisheries Resourcesand Ecology of the Major Population in Fujian Offshore Waters

本文通过对福建近海主要渔获种类组成与结构的变化和大头狗母鱼、多齿蛇鲻、蓝圆鲹、鲐鱼和竹荚鱼的种群结构及其生态学参数、捕捞死亡系数、开发比率的变化的研究,揭示了近海渔业开发力度的加大对资源衰退及其生态学的影响,旨在为渔业决策部门制定21世纪初期福建近海捕捞渔业持续发展规划提供重要的决策依据。

This paper studies the change of composition and structure of the major eatch species and the population structure and the ecoloical parameters and the fishing mortality coefficient and exploitation rate of Trachinocephalus myops, Saurida tumdil, Decapterus maruadsi, Pneumatophor-us japonicus and Trachueus japonicus in Fujian offshore waters. The results indicated that the ecology and the resource decline are influenced by the intensity of fisheries exploitation in the offshore waters. This study provided the important scientific basis for the fisheries management department to make the Fujian fisheries sustained developing plan of early in the 21th century.
