It generally has golden brown hues with yellow under parts. Because of their piscivorous nature, brown trout can often have a detrimental effect on populations of both native fishes and nonnative sport fishes.īrown trout are a hardy trout species that competes well with other fishes and endures marginal water qualities better than most trout. In addition to fishes, brown trout also consume amphibians, rodents, and invertebrates, including insects, snails, and crayfish. During the past 100 years, the species has been established in many of the cool and cold water areas of Utah, where it is now one of the most popular sport fish in the state.īrown Trout are more piscivorous (fish-eating) than many other trout species. The Brown Trout, Salmo trutta, is native to Europe and western Asia. They are now found across the state, in lakes and even in some rivers such as the Weber. In the last 2 years, Tiger Trout have been stocked in many more waters in Utah. This is most likely in part due to their brilliant, beautifully colored skin and hard fighting abilities. ![]() Tiger trout are rapidly becoming one of the most popular trout species in Utah. Tigers are also supposed to be more resistant to diseases such as whirling disease, which makes them a good choice for stocking in waters that are known to be infested with whirling disease. Fisheries managers hope that Tiger Trout will keep Utah chubs from out competing and over-running other game fish in many of Utah’s reservoirs, such as Joe’s Valley and now also in Scofield Reservoir, as well as many others. They seem to be more willing to hunt for prey in shallower waters than many other trout subspecies are. Tiger trout are quite piscivorous (fish eaters) from an early age. The belly is yellowish orange as are the pectoral, pelvic and anal fins. Tiger Trout, a hybrid cross between a male Brown Trout and a female Brook Trout, has a unique, dark, maze-like pattern all over a brownish, gray body. Rainbow Trout are heavily stocked in almost every coldwater drainage in Utah. Irregular black spots are usually present on the head, back and sides. The reddish horizontal band typifies the species. A mature rainbow is dark green to bluish on the back with silvery sides. Stream residents and migrant spawners are darker and have more intense colors than lake residents or nonspawners. Rainbows are raised in state fish hatcheries, and stocked as fingerlings, fry, and catchable sized fish in nearly all Utah waters.Ĭolors vary greatly with patterns depending on habitat, size, and maturity. Rainbow Trout have been the staple of the Utah DWR’s management program for many decades. Rainbow Trout are heavily stocked by the Utah Division of Wildlife Resources (DWR) in coldwater lakes and streams all over the state, as well as in the state’s “Community Fisheries”. It is present in more waters across the state than any other fish species. Rainbow Trout is perhaps the most popular species of fish in Utah. Today, the other native strains are becoming more extensively used in the sport-fisheries programs and are being re-introduced to many of their former habitats. It is lightly spotted with distinctly round spots concentrated toward the tail area. Yellowstone Cutthroat (not pictured) are native to Snake River drainages such as the Raft River Mountain area of northwest Utah and had been the predominant subspecies used in management programs throughout the state. Spotting is usually concentrated posteriorly. ![]() The males, in spawning condition, have bright crimson stripes along the sides and the stomach. The Colorado River Cutthroat evolved in the Colorado/Green River drainages and is noted for its brilliant coloration. The deep orange pelvic and anal fins readily distinguish Bear Lake Cutthroat from Rainbow Trout. They, particularly the Bear Lake cutthroat strain, often lack the bright crimson jaw slash that, at times, may be yellow or gray. They are clothed in subdued colors of silver-gray to charcoal upper body with bronze coloration and subtle hues of pink on flanks during spawning. The Bonneville Cutthroat inhabited the Bonneville Basin and has sparsely scattered, large, and very distinctly round spots over the upper body, with few spots on or near the head. State officials have been stocking this species in increasing numbers in recent years to make sure that our native species (and our official State Fish) continue to thrive for years to come. Although they are often mistaken for Rainbow Trout, they lack the iridescent pink stripe or the white tipped pelvic and anal fins of the rainbow trout. Except for the Bear Lake Cutthroat strain, cutthroats are best distinguished by their crimson slash along the lower jaw. Four sub-species have evolved from the only trout that is actually native to Utah.
