ABSTRACT
But fishery resources (including marine mammals) create their own incentive for management: if enough members of a given species remain in the ocean, they will reproduce and thereby create the next generation, and at least some of them do so on a reasonably short time frame for natural resources. If those who harvest them can successfully cooperate to ensure that sufficient numbers remain, they will be able to continue harvesting these resources indefinitely. Yet even with this incentive structure it has been difficult to manage international fisheries or marine mammal populations successfully.
