The huchen (Hucho hucho) (, from German), also known as Danube salmon or redfish (), is a large species of freshwater fish in the family Salmonidae native to the Danube basin in Central and Eastern Europe. It is the type species of genus Hucho (a.k.a. the taimens), being closely related (in the same subfamily) to salmon, trout, char and lenoks.
==Distribution == The huchen is endemic to the Danube basin in Europe where the remaining population is threatened primarily by river damming, resulting in habitat fragmentation and loss through river impoundment and disruption of the longitudinal continuity of rivers, cutting away fish from its spawning grounds, with overfishing and fisheries mismanagement as an additional issue in many areas. Damming and all these other problems are especially visible in the Balkans.
