Natural fish is a rare and precious fish that is distributed naturally in the middle and upper reaches of major rivers in the northern provinces, such as Lo, Gam and Mien rivers. The fish is famous as one of the five "advanced king" fish species because of its delicious meat quality. Currently, the fish has been listed in the Red Book of Urgent Protection, Level V. This is a late maturing species, after about 10 years, the fish start spawning, but the survival rate is low, only about 30% to 40%. Faced with that situation, in order to protect precious genetic resources, Ha Giang Fisheries Center, with the help of Aquaculture Research Institute 1, has successfully implemented techniques for artificial spawning of fish and the Center has become the first unit to master the technique of breeding and artificial reproduction of wild fish. Thanks to that, Ha Giang proactively source seed to develop fish farming, and at the same time protect Ha Giang's precious genetic resources.
In Ha Giang, fish is associated with the cultural life of the Tay ethnic group. The Tay people cherish the fish as valuable wealth, they offer it to the heavens and the earth, their ancestors to pay their respects. With the traditional breeding method, Ha Giang fish is famous for its delicious taste and high nutritional value, so the price of fish in Ha Giang is also higher than in some other areas.
