Abstract
It is now officially recognized by the governments of Australia and Japan that the southern bluefin tuna fishery has been overexploited and that harvests must be controlled. A dynamic programming model applicable to multicohort fisheries is developed for finding approximately optimal time-dependent quotas. Results from applying the model to the southern bluefin tuna fishery indicate that restricting or eliminating the Australian catch of under 4-year-olds would benefit both countries.Environmental Economics and Policy, International Relations/Trade, Resource /Energy Economics and Policy,
