摘  要：
鲐鱼是我国近海重要经济鱼类,如何综合考虑生物、经济和社会效益来科学制定渔业管理目标是确保该资源可持续利用的重要研究内容。根据中、日、韩三国鲐鱼围网生产作业数据及相关经济数据,构建基于Schaefer剩余产量的生物经济模型,探讨不同管理目标下的产量及其对应捕捞努力量,以及1年(短期)、5年(中期)和10年(长期)的经济效益和资源状况。结果表明,最大持续产量(MSY)、最大经济产量(MEY)和生物经济平衡点(BE)对应的捕捞努力量(以我国大型灯光围网的单位网次产量为准)分别为23964网次,13816网次和27631网次,其对应的第1年产量和利润分别为39.29万t和5.56亿元,22.65万t和3.20亿元,及45.30万t和6.41亿元;前5年累计的产量和利润分别为181.88万t和19.78亿元,131.04万t和25.81亿元,及192.10万t和13.12亿元;前10年累计的产量和利润分别为354.62万t和34.53亿元,272.32万t和57.24亿元,及362.08万t和14.07亿元。研究表明,以BE为管理目标则其短期经济效益为最大,而以MEY为管理目标则其长期经济效益为最大。探讨了不同管理方法对鲐鱼渔业所产生的影响。

摘  要：
Chub mackerel is an important commercial fish in the coast waters of our country.How to determine the goal of fisheries management by considering the biology,economic and society is one of the important contents in the sustainable utilization of fishery.According to the yield data of light purse seine fisheries of China,Japan and South Korea and the relative economic data,the Schaefer Bio-economic model is used to estimate the yield and corresponding CPUE on the basis of different management goal and the economic benefit and resource conditions under the short-term aim(1 year),mid-term(5 years) and long-term aim(10 years).The result shows that on the basis of Maximum Sustainable Yield(MSY),Maximum Economic Yield(MEY) and Bionomic Equilibrium(BE),the fishing effort should be limited to 23.96 thousand nets,13.82 thousand nets and 27.63 thousand nets respectively,and the corresponding yield and benefit in the first year are 392.9 kiloton and 0.56 billion yuan,226.5 kiloton and 0.32 billion yuan and 450.3 kiloton and 0.64 billion yuan;the accumulative yield and benefit in 5 years are 1.82 megaton and 1.98 billion yuan,1.31 megaton and 2.58 billion yuan and 1.92 megaton and 1.31 billion yuan,the accumulative yield and benefit in 10 years are 3.55 megaton and 3.45 billion yuan,2.72 megaton and 5.72 billion yuan and 3.62 megaton and 1.41 billion yuan.The results have shown that the short-term economic benefits are the largest when the BE is considered as the management goal,while the long-term economic benefits are largest when the MEY is recognized as the management goal.This article also discussed the impact of fisheries under some management methods.
