Primary water types where this species is found.
Tiger trout are a sterile cross between brown trout and brook trout, so Idaho fish are present through stocking rather than natural reproduction. Built from two coldwater trout lineages, they often show the aggressive, opportunistic feeding habits anglers expect from a prowling predator.
Young fish eat insect larvae; larger tiger trout key on crustaceans and fish.
