Giant Hucho is a rare cold-water carnivorous fish in the north, with a body length of several meters and a weight of hundreds of kilograms. It is fierce and alert, hiding in deep water for many years. During the breeding season, the fish body is reddish brown, which is called Dahongyu. It has been extinct in most parts of the world, and only a small amount remains in Kanas Lake, Xinjiang.

Hucho is a family of salmoniformes, salmonidae, salmoninae and hucho. Commonly known as Hucho taimen, Hucho taimen, Hucho taimen (northeast) and Dahong taimen (Xinjiang), it is an extremely endangered fish. Long, slightly flat, cylindrical. The head is flat, the tip of the nose is cracked, and it is in the terminal position. The maxilla is obvious and free, extending backward to the posterior edge of the eye.

Extended data:

Hucho is mainly distributed in Heilongjiang, Tumen and Irtysh rivers in China. Foreign countries are distributed in rivers such as Lena River to Bochaola River in Siberia, Volga River in Eastern Europe and the upper reaches of ural river.

Hucho taimen grows faster and at the same speed, which belongs to large economic fish. Generally, an individual weighs more than 3 kg, the largest can reach 50 kg, and the length exceeds 1 m. The meat is delicious and tender, and it is a kind of nutritious fish. It is also a specialty in alpine areas and a precious food in producing areas.

There is no detailed report on the resources of Hucho taimen, but according to the fishery resources in Heilongjiang Province (1985), the number of Hucho taimen in Heilongjiang Province is obviously lower than in the past, and the catch in the whole province is almost negligible. Mainly due to overfishing during the breeding period, the supplementary population is greatly reduced, and environmental pollution destroys the living environment, resulting in a significant decline in resources. At present, no effective protection measures have been formulated.
