Bio-economic Model forDosidicus gigasin the southeast Pacific Ocean
摘要
Abstract
The jumbo flying squid (Dosidicus gigas) is one of important economic cephalopod species. In order to ensure the sustainable utilization of fishery, reasonable management strategies should be made by considering ecological, economic and social benefits which based on Gordon-Schaefer bio-economic model. The catch data from China between 2003 and 2012,and 10 scenarios with different fishing effort was designed, which combined with biology, economy and society, accumulated benefit in 1 year, 5 years, 10 years, 20 years. The result shows that the scenarios 6 and the scenarios 7 bring great economic benefit in the medium in the long run and also keep the resource in the maximum sustainable yield. Although higher fishing effort (like scenarios 1 with 1,110,000 times of fishing) can bring better social benefits in the short run, it will badly destroy the resource and the long-term benefits. In conclusion, the most suitable fishing effort should be controlled between 810 000 to 860 000 times.关键词
