Tóm tắt
Cua biển (Scylla paramamosain) là một trong những đối tượng quan trọng trong nuôi trồng thủy sản. Thí nghiệm được thực hiện tại Trường Cao đẳng Cộng đồng Cà Mau nhằm xây dựng quy trình nuôi cua gạch trên hệ thống bể tuần hoàn và đa dạng hóa mô hình nuôi thủy sản ở Đồng bằng Sông Cửu Long. Trong thí nghiệm này, cua được nuôi với các độ mặn khác nhau: 5, 15, 25 và 35‰ được thử nghiệm với ba lần lặp lại cho mỗi nghiệm thức (NT). Cua cái có gạch non được nuôi với mật độ 20 con/m2 trong các bể 200 L kết nối với hệ thống lọc sinh học và cho ăn bằng cá tạp (3% trọng lượng cơ thể, 3 lần mỗi ngày). Sau 33 ngày nuôi, kết quả cho thấy tỷ lệ sống của cua đạt gạch ở các NT 5, 15, 25 và 35‰ lần lượt là 54,3%, 64,8%, 95,8% và 91,5%. Tốc độ tăng trưởng theo ngày và tăng trưởng đặc biệt giữa các NT lần lượt là 0,51 - 0,60 g/ngày và 0,17 - 0,20 %/ngày. Tuy nhiên, khác biệt không có ý nghĩa giữa các NT (P > 0,05). Khối lượng gạch (dao động từ 19,33 đến 28,67 g) và tỷ lệ khối lượng gạch trên gan tụy (từ 147,22 đến 220,24%) của cua trong các NT cao hơn so với ban đầu, nhưng khác biệt không ý nghĩa (P > 0,05) giữa các NT. Nhìn chung, nghiên cứu này cho thấy nuôi cua gạch ở độ mặn 25‰ cho lợi nhuận tốt nhất. Kết quả này góp phần cải tiến kỹ thuật và có thể ứng dụng vào thực tiễn nuôi cua gạch.
