The tiger trout is a hatchery-produced hybrid. It is a cross between a male Brown Trout and a female Brook Trout. They have a yellowish orange belly and have the stripes of a tiger, and hence, the name. They have a vigorous appetite and like to prey on smaller fish found in shallow waters; and this has made them a favorite among anglers.
Since the chromosomes are somewhat different between these two species, and since these two species do not naturally habitate the same waters in significant quantities, they seldom occur naturally. Also, the hatcheries have difficulty producing large numbers of fish and it takes many fertilized eggs to produce a few tigers. Some states like New York and Utah have programs to raise and release these beautiful fish.
