Danube salmon huchen (Hucho hucho) is of European origin. The population of Danube salmon can be seen in England, Canada, the USA, Finland, Sweden, Switzerland, France, Spain, and Belgium. A huchen fish, also known as a Danube salmon, is a freshwater fish found in marshy water bodies like lakes, ponds, and river basins. These fishes are monogamous by nature and mostly live in isolation. The mating period is the only time when huchens are seen socializing. After the hatching of eggs, the females are most likely to leave and the male fish takes care of the offspring. Until the offspring grow, they feed on larvae and insects and leave the nests once they are large enough.

Huchens mostly feed on smaller fishes, insects, worms, and larvae of other fishes. In most cases, they are treated as a source of food by Europeans. Due to excessive practicing of fishing, the population of huchens has decreased over the years and it is now considered a threatened species.
