全球渔业活动消耗自然资源的速度远高于资源自身的补充速度[1-4],由此造成的过度捕捞和资源衰退已成为世界各国面临的共同难题。东海大陆架独特的海流系统和丰富的陆源输入物孕育了丰富的生物资源和良好的陆架渔场,是我国沿近海捕捞的高产区。但随着长期的高强度捕捞和海域环境 Global fisheries consume natural resources at a much higher rate than those of natural resources [1-4]. Overfishing and resource depletion caused by this have become a common challenge for all countries in the world. The unique current system and rich terrestrial inputs of the East China Sea continental shelf have given birth to abundant biological resources and good shelf fisheries. It is a high-yielding catchment area along the coast of China. However, with the long-term high-intensity fishing and marine environment
