| Abstract: | A 19-cohort bioeconomic model is developed for the southern bluefin tuna fishery. The fish are long-lived and highly migratory. They are harvested as juveniles by Australia and Japan in Australian waters, and as adults by Japan on the high seas. The potential for conflict between Australian and Japanese fleets therefore exists in the exploitation of the fishery. The model is used to compare Japanese and Australian social rents and harvest levels through time under joint maximization, and under duopoly. |
