Abstract
: The purpose of this paper is to estimate the optimal CO 2 emission in the maximum economic yield (MEY), maximum sustainable yield (MSY), and open access (OA) using a bioeconomic model. The results are as follows; in the case of E MEY , E MSY , and E OA levels, CO 2 emissions are estimated at 150,704,746CO 2 /kg, 352,211,193CO 2 /kg, and 301,409,492CO 2 /kg respectively. We show that the E MEY is more efficient than the other levels. That is, the level of E MEY signifies the optimal economic fishing usage as the most economically efficient usage for large purse seine fishery catching mackerel species. The emission of CO 2 in E MEY is the lowest level. Also, the impacts of climate changes such as ocean temperature increase, ocean acidification, and the combined impact thereof show that the biomass of mackerel decreases.
