Author: (Linnaeus, 1758)
FBname: Huchen
Comments: Usually solitary, inhabits deeper regions of swift flowing streams with oxygen rich waters.  Adults are territorial but not solitary (Ref. 26170).  Carnivore.  Juveniles feed mainly on invertebrates and adults mostly on fishes, but also prey on amphibians, reptiles, small mammals and waterfowl (Ref. 26170).  Important sport fish with minimum size of catch from 50-55 cm.  Transplantations of young artificially incubated and reared fish have not been successful.  Depletion of stocks due to overexploitation, industrial pollution, waterway redirection and badly designed or non-existent fish ladders in dams and reservoirs.  Territorial, but migrates short distances upstream for spawning (Ref. 556).  Reported to be one of the biggest freshwater fishes of the world, reaching  a length of over 2 m and weight of over 100 kg (Ref. 26170); which is probably erroneous (A. Mangold, pers. comm.).
