The tiger trout, Salmo trutta X Salvelinus fontinalis, is a hybrid sport fish created by crossing a brown trout with a brook trout. The Utah Division of Wildlife Resources has been exploring the fisheries value of the tiger trout for some time now, and the fish has been introduced to Mill Meadow Reservoir and Barney Lake. Because the tiger trout is a hatchery-produced hybrid, it does not occur naturally anywhere in Utah. It does rarely occur "naturally" in some other states, however, where reproducing populations of brown trout and brook trout are found in the same waters.

Like other trout, the tiger trout eats invertebrates and fishes. One problem with the tiger trout is the difficulty hatcheries have producing large numbers of fish. It takes many fertilized eggs to produce a few tiger trout large enough to be stocked into Utah waters.
