Hucho
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.
