一、前言当前我国近海主要经济鱼类的利用已呈现过发现象,传统性捕捞的底层经济鱼类遭到了严重的破坏。根据FAO的报告,在东黄海区域,有经济价值的底鱼资源是过去最高水平的1/5～1/10,并且没有任何恢复的迹象。渔场矛盾十分突出,生产安排困难。然而就整个世界范围来说,特别是分布在日本沿海及东黄海的中上层鱼类资源却呈现出不断上升的趋势。据统计,1983年世界渔获量
I. Introduction At present, the utilization of the major economic fish on the coast of our country has shown the phenomenon of over-exploitation, and the bottom-level economic fishes traditionally caught have been severely damaged. According to the FAO report, in the East Yellow Sea, bottom fish resources of economic value were 1/5 to 1/10 of their highest levels in the past and showed no signs of recovery.
