Background and objectives of activities
The Pacific oyster (Tobin-nya) has long been a resource used in the Amami Islands, and it is a familiar food that regularly appears on dinner tables. However, in recent years, the catch has decreased significantly, and there are concerns that the resource is deteriorating. Not only will the income of the fishermen involved in the catch decrease, but there is also the possibility that the food culture that has used it as a daily food will disappear. In order to achieve the sustainable use of the Pacific oyster, we will clarify its ecology and the appropriate way to manage the resource.
Summary of Activities
① We will clarify the ecological characteristics of the Pacific oyster through sampling of Pacific oysters caught in various locations in the Amami Islands.
② Based on this, we will clarify the issues facing the Pacific oyster fishery.
③ We will consider, together with fishermen, the appropriate resource management that will contribute to the sustainable use of Pacific oysters.
Expected Benefits
Promotion of sustainable use of marine resources and sustainable consumption, conservation of marine resources through appropriate resource management, maintenance of local food culture
