Trout is a generic common name for numerous species of carnivorous freshwater ray-finned fishes belonging to the genera Oncorhynchus, Salmo and Salvelinus, all of which are members of the subfamily Salmoninae in the family Salmonidae. The word trout is also used for some similar-shaped but non-salmonid fish, such as the spotted seatrout/speckled trout.
The rainbow trout is a species of trout native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead is an anadromous (sea-run) form of the coastal rainbow trout(O. m. irideus) or Columbia River redband trout (O. m. gairdneri) that usually returns to freshwater to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead.
The cutthroat trout(Oncorhynchus clarkii) is a fish species of the family Salmonidae native to cold-water tributaries of the Pacific Ocean, Rocky Mountains, and Great Basin in North America. As a member of the genus Oncorhynchus, it is one of the Pacific trout, a group that includes the widely distributed rainbow trout. Cutthroat trout are popular gamefish, especially among anglers who enjoy fly fishing. The common name "cutthroat" refers to the distinctive red coloration on the underside of the lower jaw. The specific name clarkii was given to honor explorer William Clark, coleader of the Lewis and Clark Expedition.
The Californiagolden trout (Oncorhynchus aguabonita or Oncorhynchus mykiss aguabonita), is a species of trout native to California. The golden trout is normally found in the Golden Trout Creek, Volcano Creek, and the South Fork Kern River. The Golden trout is the official freshwater state fish of California since 1947.
Oncorhynchus is a genus of ray-finned fish in the subfamily Salmoninae of the family Salmonidae, native to coldwater tributaries of the North Pacific basin. The genus contains twelve extant species, namely six species of Pacific salmon and six species of Pacific trout, all of which are migratory mid-level predatory fish that display natal homing and semelparity.
The Alvord cutthroat trout, Oncorhynchus clarkii alvordensis, was a subspecies of cutthroat trout. It was known only from Trout Creek in Oregon and Virgin Creek in Nevada, although it may have lived in several of the larger Alvord Basin streams during recent times. It was native to spring-fed creeks that ran down to Alvord Dry Lake in southeast Oregon, which was a large lake during the ice ages and an isolated drainage, part of the Great Basin today. This is one of the two cutthroat trout taxa considered extinct because all known populations are hybridized with rainbow trout which were introduced into streams in the Alvord basin in the 1920s, resulting in cutbows.
Lahontan cutthroat trout is the largest subspecies of cutthroat trout, and the state fish of Nevada. It is one of three subspecies of cutthroat trout that are listed as federally threatened.
The Yellowstone cutthroat trout is a subspecies of the cutthroat trout. It is a freshwater fish in the salmon family. Native only to a few U.S. states, their original range was upstream of Shoshone Falls on the Snake River and tributaries in Wyoming, also across the Continental Divide in Yellowstone Lake and in the Yellowstone River as well as its tributaries downstream to the Tongue River in Montana. The species is also found in Idaho, Utah and Nevada.
Strawberry Reservoir is a large reservoir in the U.S. state of Utah. It is Utah's most popular fishery, receiving over 1.5 million angling hours annually and is part of the Blue Ribbon Fisheries program. Game fish in the reservoir include sterilized rainbow trout, bear lake cutthroat trout, kokanee salmon and crayfish. It is located 23 miles (37 km) southeast of Heber, Utah on U.S. Route 40. The reservoir is situated in Strawberry Valley. This valley is normally part of the Colorado River drainage. The dam was constructed to divert water into Utah Valley.
The Colorado River cutthroat trout is a subspecies of cutthroat trout native only to the Green and Colorado River basins, which are west of the Continental Divide. Cutthroat trout found in other river basins belong to other subspecies.
The Snake River fine-spotted cutthroat trout is a form of the cutthroat trout that is considered either as a separate subspecies O. c. behnkei, or as a variety of the Yellowstone cutthroat trout. The fish takes its common name from its original habitat, the Snake River of southern Idaho and western Wyoming, and from its unusual pattern of hundreds of small spots that cover most of its body, differing from the larger-spotted Yellowstone cutthroat pattern. Genetically, it cannot be distinguished from the Yellowstone cutthroat trout, and before the construction of dams, no physical barriers were between the ranges of the two subspecies in the Snake River drainage.
The westslope cutthroat trout, also known as the black-spotted trout, common cutthroat trout and red-throated trout is a subspecies of the cutthroat trout and is a freshwater fish in the salmon family of order Salmoniformes. The cutthroat is the Montana state fish. This subspecies is a species of concern in its Montana and British Columbia ranges and is considered threatened in its native range in Alberta.
The coastal cutthroat trout, also known as the sea-run cutthroat trout, blue-back trout or harvest trout, is one of the several subspecies of cutthroat trout found in Western North America. The coastal cutthroat trout occurs in four distinct forms. A semi-anadromous or sea-run form is the most well known. Freshwater forms occur in both large and small rivers and streams and lake environments. The native range of the coastal cutthroat trout extends south from the southern coastline of the Kenai Peninsula in Alaska to the Eel River in Northern California. Coastal cutthroat trout are resident in tributary streams and rivers of the Pacific basin and are rarely found more than 100 miles (160 km) from the ocean.
The Crescenti cutthroat trout or the Lake Crescent cutthroat trout is a North American freshwater fish, a local form of the coastal cutthroat trout isolated in Lake Crescent in Washington. While previously attributed to a distinct subspecies Oncorhynchus clarkii crescenti, it is not currently recognized at the subspecies rank. However the cutthroat trout of Lake Crescent do remain distinct. They have the highest known gill raker and vertebrae counts of any coastal cutthroat population. The cutthroat are believed to have been isolated in Lake Crescent after a landslide blocked the eastern outflow of the lake.
Paiute cutthroat trout is one of fourteen subspecies of cutthroat trout. Paiute Cutthroat are native only to Silver King Creek, a headwater tributary of the Carson River in the Sierra Nevada, in California. This subspecies is named after the indigenous Northern Paiute peoples.
A cutbow is an interspecific fertile hybrid between a rainbow trout and a cutthroat trout. Cutbow hybrids may occur naturally where the native ranges of both species overlap, such as between coastal rainbow trout and coastal cutthroat trout and between Columbia River redband trout and westslope cutthroat trout. While natural separation of spawning habitat limited hybridization in most native populations of rainbows and cutthroats, introduction of non-native hatchery-raised rainbow trout into the native ranges of cutthroat subspecies increased the rate of hybridization. Some native cutthroat populations are, as a result, at risk due to genetic pollution.
Birch Creek is a 6.1-mile-long (9.8 km) northeastward-flowing stream originating on the western slope of the Bear River Range in Franklin County, Idaho, United States. Its mouth is at the confluence with Mink Creek about 12 miles (19 km) northwest of Preston, Idaho. In turn, Mink Creek flows southwest to its confluence with the Bear River and, from there, its flows terminate in the Great Salt Lake.
Birch Creek is a northwesterly-flowing 8.4 miles (13.5 km) stream in Beaver County, Utah. It originates on the western slope of Birch Creek Mountain in the Tushar Mountains in Fishlake National Forest, and its waters flow west into South Creek, then under Interstate 15 south of the town of Beaver, and thence to the Beaver River, and ultimately to the Sevier River and Lake.
