چکیده

Marshal 200SC chứa carbosulfan 200g/L được sử dụng trong canh tác lúa ở Đồng bằng sông Cửu Long. Carbosulfan có cơ chế gây hại cho sinh vật qua ức cholinesterase (ChE). Cá mè vinh (Barbonymus gonionotus) sống nhiều thủy vực và nuôi xen mô hình - cá nên nguy tiếp xúc bị ảnh hưởng do thuốc này. Nghiên cứu này nhằm xác định nồng độ dưới ngưỡng chết của đến ChE tăng trưởng loài Ba Marshall (1, 10 20%LC50-96 giờ) triển khai điều kiện phòng thí nghiệm để đánh giá 96 giờ 60 ngày. Kết quả thấy độc cấp tính cao đối với cỡ giống, trị LC50-96 là 1,375 ppm (# 0,275 mg/L carbosulfan). Thông số não nhạy cảm hơn các thông trưởng. Ở 1%LC50-96 giờ, đã làm 18,4% hoạt ChE; khi FCR FI lần lượt 129,6% 116,7% chứng nhưng SGR giảm còn 74,5% chứng. ruộng cần khai.
