碩士 === 國立中山大學 === 經濟學研究所 === 99 === Tong-Kong sakura shrimp is one of important fisheries in southwest coast. Tong-Kong sakura shrimp, blue fin tuna and mullet roe are called Three Treasures of Tong-Kong . It brings significant economic benefits for local residents. This research is based on Gordon-Schaefer Model theory that combines with fishery catch statistics and operational cost data. Also, we use these data to discuss open-access fishing ground and dynamically optimal fishing ground of balance status under equilibrium level. Next step is to do stimulation analysis that based on annual fishery catch statistics of sakura shrimp. After stimulation, we can make comparisons of equilibrium values of these two fishing grounds. From analysing fishery catch statistics and fishing resource we may know that it can shows that the management of sakura shrimp tends to dynamically optimal fishing ground, and also can state that the management mechanism of sakura shrimp is an ideal of sustainable management. Then, through the example, we can understand how each variation influences fishing resources and fishing effort of these two fishing grounds. Finally, we simulate fishing resources model of two fishing grounds to show the result. If we don’t manage fishery of sakura shrimp well and keep uncontrolled fishing, not only the fishing ground will become an open-access fishery, but also fishing resources will become extinct. However, once we can manage fishing ground efficiently, it will become a dynamically optimal fishing ground and the fishery of sakura shrimp will develop sustainably.
