Abstract: Abstract:The total allowable catch of Sakura shrimp on a basis of stopping biological overfishing was estimated at TAC = 590,751 kg/season. According to this TAC, three scenarios with varied management strengths were proposed to recover this renewable resource and to prevent the economic overfishing at different paces. As a result, the economic efficiencies as compared to that of the current management will be increased to 132%, 133%, and 134% for scenarios 1, 2 and 3, respectively.
All the bioeconomic parameters estimated from the dynamic equilibrium ecosystem will be definitely traced and reevaluated yearly in future to manage the resource efficiently. Additionally, the cost-return structure of Sakura shrimp fishery is absolutely dynamic within a socioeconomic environment. For instance, the government policies (such as importing foreign labor, fuel subsidy, intensity of resource conservation, etc) and the demand and supply of market will no doubt affect the cost-return structure, in turn, which will force the total allowable catch and the number of allowable vessels to be adjusted.
The fishery as an integrated mixture has a tremendous potential for application to human affairs, since real-world situations almost always involve a biological component and a socioeconomic and political component. The three cannot be dealt with separately if one expects to find lasting solutions to critical problems.
摘要:正櫻蝦最大可捕量(TAC),估計是每年590,751公斤。據此,在保護自然資源和預防經濟性過漁的基礎上,三種不同力度的管理策略,應運而生。與目前之經營狀況比較,這三種管理策略的經濟效益將分別提高至132%、133%和134%。
針對本研究所估算生物經濟之各類參數,未來應持續追蹤,並重覆修正,提升該資源經濟之管理效率。此外,正櫻蝦漁業之成本利潤結構,必會隨社會經濟之時空變遷而改變。例如:政府政策(外勞引進、燃油津貼、資源保育力度…等)和市場供需,都會影響該漁業之成本和利潤,進而調整最大可捕量和作業漁船數。
漁業本質,具多重性;即是生物議題,亦是經濟議題,更是政治議題。漁業的經營管理,若不能針對這些議題三管齊下,將事倍功半。
