Cá bỗng là loại cá quý hiếm, phân bố tự nhiên ở vùng trung và thượng lưu các sông lớn ở các tỉnh phía Bắc như sông Lô, sông Gâm và sông Miện. Hiện nay, cá bỗng đã nằm trong sách đỏ thuộc diện cần bảo vệ khẩn cấp, cấp độ V. Đây là loài thành thục muộn, nuôi khoảng 10 năm cá bỗng mới bắt đầu sinh đẻ, nhưng tỷ lệ sống thấp, chỉ khoảng từ 30% đến 40%. Trước thực trạng đó, nhằm bảo vệ được nguồn gene quý, Trung tâm Thủy sản Hà Giang, được sự giúp đỡ của Viện Nghiên cứu nuôi trồng Thủy sản 1, đã thực hiện thành công kỹ thuật cho cá bỗng sinh sản nhân tạo và trung tâm trở thành đơn vị đầu tiên làm chủ kỹ thuật nhân giống, sinh sản nhân tạo cá bỗng, nhờ đó, Hà Giang chủ động nguồn giống để phát triển nghề nuôi cá bỗng, đồng thời bảo vệ được nguồn gene quý cá bỗng Hà Giang.

Danh tiếng của cá bỗng Hà Giang có được nhờ tổng hợp của các yếu tố tự nhiên, nguồn giống, quá trình chăm sóc. Cá bỗng Hà Giang được người Tày nuôi từ rất lâu đời nên thích nghi với nhiệt độ môi trường nước ở Hà Giang, cá khỏe mạnh, tỷ lệ sống cao.
