Hucho is a genus of large piscivorous salmonid fish known as taimens (from Finnish taimen, 'trout', through Russian тайме́нь), and is closely related to Pacific trout and lenoks (all belonging to the same tribe in the subfamily Salmoninae). Native to the cold rivers and other freshwater habitats in Eurasia, they are threatened by overfishing and habitat loss.

Species

The currently recognized species in this genus are:[1]

Image Scientific name Common name Distribution
Hucho bleekeri Sh. Kimura, 1934 Sichuan taimen Yangtze basin in China
Hucho hucho (Linnaeus, 1758) huchen, Danube salmon endemic to the Danube basin in Europe
Hucho ishikawae T. Mori, 1928 Korean taimen North Korea and China
Hucho taimen (Pallas, 1773) Siberian taimen, Siberian giant trout, and Siberian salmon Siberia

In addition, the Sakhalin taimen was formerly placed in this genus, but genetics and other evidence has shown that it belongs in its own monotypic genus as Parahucho perryi.[2][3][4]
