Summary:Aim: Fisheries stock rebuilding plans (FSRP) and seasonal area closures have not yet reached the desired stock level as they were implemented separately. Therefore, these two policies were integrated in this study to determine the nature of stock enhancement. Methodology: FSRP and seasonal closures were integrated in this study to determine the nature of stock enhancement of targeted marine species (sandfish, blue crab, octopus, skate ray, and yellow croaker). In contrast, tokobushi abalone, cod, filefish, Korean flounder, and purplish Washington clam were managed only by FSRP. The catch per unit effort (CPUE) was examined to evaluate the improvement of depleted stocks. Results: Overall, stocks showed expected recovery during FSRP with seasonal closure. CPUEs of blue crab, octopus, skate ray, and yellow croaker significantly increased during the period of integrated policy implementation. Stock reclamation was found higher within the first five years than ten years of FSRP regime. Blue crab, yellow croaker and skate ray showed similar fluctuations in the abundance. Only the abundance of cod increased significantly by FSRP with the year-round open fishery. Interpretation: Integrated management seemed a suitable means for marine stock management. Planning for every five-year investigation to ensure sound ecological interaction of all components will contribute more to combined management practices.
