    Abstract:

    Based on the catch data of purse seine fishery of China from 1998 to 2015 and Japanese Resource Assessment of Chub mackerel and economic data, the Pella-Tomlinson model was used to calculate the Maximum Sustainable Yield (MSY), Bio-economic Equilibrium (BE),Maximum Economic Yield (MEY) and their corresponding fishing efforts. Taking into account different factors of biology, economy and society, 10 different fishing schemes was designed to compare the biological, economic and social benefits for 5 years,10 years and 20 years. The results show that the resource abundance of the Chub mackerel in East China Sea and the Yellow Sea decreased year by year; Increaseing investment in fishing effort will have a serious impact on economic,output and resources. The study determined that considering the biological, economic and social factors, Option 10 is the optimal fishing strategy, i.e. the weights of fMSY,fBE and fMEY are 0.25, 0.25 and 0.50. The accumulated profit and output of 5 years under this strategy will be 3.019 billion yuan and 1 320 200 tons, and the resources will be 867 300 tons 5 years later.
