Abstract

Assessing the current status of gill net and trawl fisheries in the offshore area of Ca Mau province was conducted from September 2023 to October 2024. The study interviewed 113 fishermen about the technical and financial aspects of these two fishing methods. Results show that both fisheries can operate year-round. The average annual yield of the trawl fishery (395 tons/ship/year) was significantly higher than that of the gill net fishery (72.6 tons/ship/year). The ratio of trash fish of the gill net fishery (2.66%) was much lower than that of the trawl fishery (53.1%). Trawl vessels had an average annual revenue of 13,384 million VND/ship/year and an average profit of 4,363 million VND/ship/year. For gill net vessels, the average annual revenue was 3,257 million VND/ship/year, with a profit of 1,130 million VND/ship/year. The profit ratio of the gill net fishery was 0.53 times compared to 0.48 times for the trawl fishery. The gill net fishery has a lower trash fish ratio and impact on the decline of aquatic resources than that of trawl net, so it should be promoted to enhance sustainability.

Tóm tắt

Việc đánh giá hiện trạng khai thác của nghề lưới rê và lưới kéo ở vùng khơi tỉnh Cà Mau được thực hiện từ tháng 9/2023 đến tháng 10/2024. Trong nghiên cứu, 113 ngư dân đã được phỏng vấn về khía cạnh kỹ thuật và tài chính của hai nghề này. Kết quả cho thấy cả hai nghề có thể khai thác quanh năm. Sản lượng trung bình của nghề lưới kéo là 395 tấn/tàu/năm, cao hơn so với nghề lưới rê (72,6 tấn/tàu/năm). Tỉ lệ cá tạp của nghề lưới rê (2,66%) thấp hơn nhiều so với nghề lưới kéo (53,1%). Tàu lưới kéo có doanh thu trung bình 13.384 triệu đồng/tàu/năm và lợi nhuận trung bình 4.363 triệu đồng/tàu/năm. Đối với tàu lưới rê, doanh thu trung bình là 3.257 triệu đồng/tàu/năm và lợi nhuận thu được là 1.130 triệu đồng/năm. Tỉ suất lợi nhuận của lưới rê là 0,53 lần và nghề lưới kéo là 0,48 lần. Nghề lưới rê có tỉ lệ cá tạp thấp và ít tác động làm suy giảm nguồn lợi thủy sản so với lưới kéo nên cần được khuyến khích để cải thiện tính bền vững.
