中文摘要:
      鲐鱼是我国近海重要经济鱼类,其资源的可持续利用和科学管理一直受到人们的关注和重视。以Gordon Schaefer生物经济模型为理论依据,采用中、日、韩3国1998-2008年灯光围网渔业的生产作业数据以及相关的经济数据,估算东、黄海鲐鱼的最大可持续产量(MSY)、最大经济产量(MEY)和生物经济平衡点(BE)及其对应的捕捞努力量。在此基础上,设计出多种基于不同权重的生物、经济和社会目标的捕捞方案,建立东、黄海鲐鱼生物经济社会综合模型,比较其在不同捕捞方案下的短期(1~5年)、中期(10年)、长期(20年)的经济效益和社会效益以及渔业资源状况。结果表明,东、黄海鲐鱼资源量正处于或已经处于过度捕捞状态;以MEY为管理目标的长期经济效益为最大,且资源状况保持最好,但社会就业率较低;以BE为管理目标的当前以及短期效益较大,且可以解决大量就业问题,但长期经济效益为最低,且资源状况最差;而捕捞方案9的经济和社会综合效益为最好,且资源状况也较佳。研究认为,综合各方面因素,最佳的捕捞方案为方案9,即适宜捕捞努力量应控制在19 889网次。
英文摘要:
      Chub mackerel (Scomber japonicus) is an important economic species in the coastal waters of China, and its sustainable utilization and scientific management has been attractive and attentions by peoples. In this paper, based on Gordon Schaefer bio economic model, we use the catch data of purse seine fishery and economic data from China, Japan and Korea from 1998 to 2008 to calculate the Maximum Sustainable Yield (MSY), Maximum Economic Yield (MEY), Bio economic balance point (BE) and their corresponding fishing efforts. Combined with the above results, the bio economic social synthesize model based on different weight is established by considering the impact of biology, economy and society, to compare the economic benefit and resources status of different management objectives at short term (1-5 years), middle term(10 years) and long term(20 years). The results showed that the resources of chub mackerel is overfishing now. If the MEY is considered as the management objective for maximum long term economic benefit, the resources status keeps well but with low social employment rate. If the BE is considered as management objective for maximum short term economic benefit, it will provide a plenty of employment, but long term economic benefit is the lowest and the resources status will be worst. It is found the comprehensive benefit of fishing program 9 in all aspects is the best. The results showed that the most suitable fishing efforts is 19 889 fishing nets by considering the impact of all factors, and the suitable CPUE should keep between the corresponding fishing effort of MEY and MSY, and slightly close to MSY.
