Fishermen in Binh Dinh province, Vietnam, are facing difficulties due to a regulation that requires skipjack tuna to be a minimum size of 500mm before being exploited. This regulation has led to a decrease in catch size and a drop in the price of skipjack tuna, making fishing more difficult and less profitable. As a result, many fishing boats, including the BD.98207-TS of To Van Thong, are stuck on shore. The situation has affected aquatic production activities and the lives of many fishermen. The Department of Agriculture and Rural Development of Binh Dinh province has proposed a review of the regulations on the minimum size allowed to exploit skipjack tuna and other aquatic species living in natural waters. The review is expected to contribute to the conservation and sustainable development of aquatic resources while not significantly affecting fishing activities.
