APPLICATION OF OPTIMAL HARVESTING STRATEGIES TO FISHERIES MANAGEMENTS
The concept of the maximum sustainable yield has been important to the development of fishery science. A variety of growth curves have been developed to model both unpredated, intraspecific population dynamics and more general biological growth. The analysis is based on a bio-economic model which is examined as a dynamic control system in continuous time. A target point is obtained that maximizes yield while minimizing the impact of fishing on population biomass and that reduces the risk. Given these objectives and the various constraints determined by the state of the model at each point of time, their maximization problem of sustainable yield is solved. The corresponding values of their control variables then constitute their behaviors. Feasible development paths arc discussed in detail. A greater focus on the economic matters will take resource managers further in the direction of sustainable management of increasingly scarce marine resources.
