摘  要:
阿根廷滑柔鱼是重要的经济头足类之一,主要分布在西南大西洋海域,是中国大陆及台湾地区等鱿鱼钓船重要的捕捞种类之一。本研究综合考虑生物、经济、社会3个目标着手探讨西南大西洋阿根廷滑柔鱼资源可持续利用的最适方案。以2001-2010年中国大陆、中国台湾省及福克兰群岛鱿钓生产统计数据为基础,利用Gordon-Schaefer生物经济模型对西南大西洋阿根廷滑柔鱼南部巴塔哥尼亚种群资源进行分析,模拟了13种捕捞策略下短期(1-5年)、中期(10年)、长期(20年)的资源开发结果。研究认为,方案8、方案11时的捕捞策略,捕捞努力量分别为30.14万船次、30.75万船次,既不会对阿根廷滑柔鱼资源构成较大威胁,同时又兼顾到社会效益和经济效益,可作为西南大西洋阿根廷滑柔鱼南部巴塔哥尼亚种群资源管理的最适方案。

摘  要:
Illex argentinus mainly distributed in the southwest Atlantic Ocean is one of the important economic cephalopod in the world,and also is one of the important fishing targets by China's mainland and Taiwan squid jigging vessels. Its development and resource utilization have attracted us. Therefore,this study focused on considering biological,economic,social goals,aiming to point out the optimum exploitation strategy of I.argentinus resources in the southwest Atlantic. Based on the catch data from Chinese mainland,Taiwan province of China and the Falkland Islands during 2001- 2010,the biological economic model of Gordon-Schaefer is used to analyze the exploitation strategy of I. argentinus in the southwest Atlantic and the 13 kinds of fishing strategy in the short( 1- 5 years),medium( 10 years) and long-term( 20 years) periods are simulated. The results suggest that plans 8 and 11 with fishing efforts of 301 400 times and 307 500 times,respectively,will not pose a threat to the squid resources,but will produce the best social benefits and economic benefits. Therefore,plans 8 and 11 can be used as the optimal fishing strategy for managing I.argentinus population in the southwest Atlantic.
