The resource management of bluefin tuna has been strengthened worldwide; in Japan, bluefin tuna aquaculture production has increased as a result of this change. In particular, several large companies have entered the domestic bluefin tuna farming industry, and the impact of this shift on the market has been considerable. In this study, we examine the criteria by which these companies determine the locations of their respective production areas; we also analyze how they evaluate various production areas. The data used in our analysis are derived from hearing investigations for persons working in the bluefin tuna farming sectors.
