- An ecosystem-based approach is introduced to manage fisheries resources in marine ranching areas by considering ecological interactions of organisms in the ecosystem. The ecosystem structure model (ESM) analyses ecotrophic levels among functional groups in the ecosystem and the ecosystem dynamic model (EDM) conducts dynamic simulation of the ecosystem according to the fishing mortality intensity or environmental changes. Here, we developed two models : the fishery stock enhancent model which estinates parameters to enhance required fishery stocks by artificial releasing and the ABC (acceptable biological catch) estimation model for an effective fishery resource management. In addition, methods for estimating parameters required for the ecosystem models and population models were also investigated. Finally, a necessity for studying the ecosystem-based approach for the management of fisheries resources was stressed.
