Hucho taiwanese is a cold-water and fresh-water carnivorous fish, mainly distributed in the Volga River basin in the north, Bojola River basin in the east, Heilongjiang River basin in the south and Lena River basin in the north of Asia.

Fierce, large in size, with a body length exceeding 1 m, individuals weighing 50 kg have been found, but individuals weighing up to 4 m and 90 kg have been found, preying on fish and frogs, snakes, rats and birds that live on water.

Fierce, large in size, with a body length of more than 1 m, but individuals with a body length of 4 meters and a weight of 90 kg have been found, preying on fish and frogs, snakes, rats and birds that live on water. Hucho is a precious fish because its meat is delicious. Long, slightly flat, cylindrical. The head is flat, the tip of the nose is cracked, and it is in the terminal position.

During spawning, both sexes are bronzed, and the lower leaves of ventral fin and caudal fin are orange-red, which is more obvious in males. Pyloric caecum 205-2 19.
The growth area and distribution range of Hucho taimen are mostly 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. 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.
The growth environment of Hucho taimen has a great influence on its body length and size. In the case of adequate food, its length can even reach more than 3 meters.
Although the hucho is very big, it is not the largest fish in the world. The largest freshwater fish in the world is a kind of fish in Cambodia.
