Asia: Siberia, Korea and North China. A subspecies, Brachymystax lenok tsinlingensis is endemic to parts of the Taibaishan Mountain in the Qinling Mountains, particularly in the Heihe River at the eastern foot, the Shitouhe River at the northern foot and the Xushui and Taibaihe rivers at the southern foot of the mountain. Status of threat: Vulnerable (Ref. 45563).
A slow-growing fish which inhabits rivers. A cold water fish and never goes to the ocean; finds deep cold waters during summer; can be found under the ice in late fall and winter (Ref. 12218).
