Abstract：Ommastrephes bartramii is an important economic species of the pelagic fishery of China,and the sustainable use of fish resources is an important part of the research.In this study,basing on the Gordon-Schaefer bioeconomy model,the bio-economic social synthesis was established by consider-ing the impact of biology,economy and society.We used the production and related economic data of the north Pacific Ocean from 1995 to 2019 to analyze the impact of the change in fuel cost on the sus-tainable use of fish resources.Up to 9 fishing scenarios were drawn to simulate the accumulative stock biomass variation,accumulative catch and accumulative profit changes under different scenarios of fuel cost for short-term(1-5 years),medium-term(10 years)and long-term(20 years)resources.The re-sults showed that both scenarios 6(2.5％reduction in fuel cost)and scenarios 7(5％reduction in fuel cost)obtained not only considerable fishery profits but also protected soft fish resources from overfis-hing.Considering the influence of biological,economic,social and ecological factors,they can be used as the optimal scenarios to realize the optimal allocation of resources.
