In past articles, researchers divided the sea into two areas: One of areas for fishing; the other as a marine protected area which protects the fishery resources. With the MPAs established, short-term economic profit will be negatively impacted. However, MPAs bolster fisheries renewability, and thus could increase the fish stock via movement of fishes in the ocean. With by time, the sustainable harvest of MPAs could not only obtain the maximize profit and keep the marine stocks stable, but also have the utility effect to face uncertain situations. This study is the combination of different design concepts which protect fishery resources through MPAs. One area is open tfor the fishing, the other is the marine protected areas intended for regeneration of fishery resources. This concept is different from the past literatures, which only keep the marine stock stable and rely on fish movement and inhenent renewable capacity in a single area. The intent of this paper is to establish two areas that atternate roles for when the catch rates reaches a certain time or level. The original fishing area is converted into a marine protected area, while the original MPA is opened for fishing. This study will explore a managing method which exchanges the state of these two areas, for the fishery’s economic profit and the benefit of restoring the fishery resources. The optimal time for transitioning two areas, is controlled by human efforts. In addition achieving the sustainable development of biological diversity and making the development sustainable, this strategy ensures stability and long-term fishery economic benefit. According to the simulation analysis, this study shows that exchanging MPAs and fishing areas, in addition to economic advantage, has the long-term benefit of ensuring the quantity of resources, biodiversity and the ecological balance of the areas. Alternating conversion of these states of the two areas also provides ecological environment restoration spaces which maintain a stable ecosystem. Even with negative external stimuli, the ecosystem can still remain functional.
