The United States Fish and Wildlife Service is a U.S. federal government agency within the U.S. Department of the Interior which oversees the management of fish, wildlife, and natural habitats in the United States. The mission of the agency is "working with others to conserve, protect, and enhance fish, wildlife, plants and their habitats for the continuing benefit of the American people."
The National Fish Hatchery System (NFHS) was established by the U.S. Congress in 1871 through the creation of a U.S. Commissioner for Fish and Fisheries. This system of fish hatcheries is now administered by the Fisheries Program of the U.S. Fish and Wildlife Service (Service), an agency within the United States Department of the Interior.
The Big Hole River is a tributary of the Jefferson River, approximately 153 miles (246 km) long, in Beaverhead County, in southwestern Montana, United States. It is the last habitat in the contiguous United States for native fluvial Arctic grayling and is a historically popular destination for fly fishing, especially for trout.
The rainbow trout is a species of trout native to cold-water tributaries of the Pacific Ocean in North America and Asia. 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.
Steelhead, or occasionally steelhead trout, is the anadromous form of the coastal rainbow trout (Oncorhynchus mykiss irideus) or Columbia River redband trout. Steelhead are native to cold-water tributaries of the Pacific basin in Northeast Asia and North America. Like other sea-run (anadromous) trout and salmon, steelhead spawn in freshwater, smolts migrate to the ocean to forage for several years and adults return to their natal streams to spawn. Steelhead are iteroparous, although survival is only approximately 10–20%.
The cutthroat trout is a group of four fish species of the family Salmonidae native to cold-water tributaries of the Pacific Ocean, Rocky Mountains, and Great Basin in North America. These four species are the Coastal, Westslope, Lahontan, and the Rocky Mountain. As a member of the genus Oncorhynchus, it is in the Pacific trout group, which 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 Arctic grayling is a species of freshwater fish in the salmon family Salmonidae. T. arcticus is widespread throughout the Arctic and Pacific drainages in Canada, Alaska, and Siberia, as well as the upper Missouri River drainage in Montana. In the U.S. state of Arizona, an introduced population is found in the Lee Valley and other lakes in the White Mountains. They were also stocked at Toppings Lake by the Teton Range and in lakes in the high Uinta Mountains in Utah, as well as alpine lakes of the Boulder Mountains (Idaho) in central Idaho.
The Coquitlam River is a tributary of the Fraser River in the Canadian province of British Columbia. The river's name comes from the word Kʷikʷəƛ̓əm which translates to "Red fish up the river". The name is a reference to a sockeye salmon species that once occupied the river's waters.
Lake Oroville is a reservoir formed by the Oroville Dam impounding the Feather River, located in Butte County, northern California. The lake is situated 5 miles (8 km) northeast of the city of Oroville, within the Lake Oroville State Recreation Area, in the western foothills of the Sierra Nevada. Known as the second-largest reservoir in California, Lake Oroville is treated as a keystone facility within the California State Water Project by storing water, providing flood control, recreation, freshwater releases to assist in controlling the salinity intrusion into the Sacramento-San Joaquin Delta and protecting fish and wildlife.
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.
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 Metolius River is a tributary of the Deschutes River in Central Oregon, United States. The river flows north from springs near Black Butte, then turns sharply east, descending through a series of gorges before ending in the western end of Lake Billy Chinook. The unincorporated community of Camp Sherman lies astride the southern end of the river. The name of the river comes from the Warm Springs or Sahaptin word mitula, meaning white salmon and referring to a light colored Chinook salmon and not a whitefish.
The Nimbus Dam is a base load hydroelectric dam on the American River near Folsom, California. Approximately 8,700 acre-feet (10,700 dam3) of water is retained by the dam. It is responsible for the impoundment of water from the American River to create the Lake Natoma reservoir. The dam stands 87 feet and spans 1,093 feet. The Nimbus powerplant consists of two generators. Each generator produces enough electrical power to power over 200,000 100-watt light bulbs, about 15,500 kilowatts of electrical power. Nimbus Dam consists of 18 radial gates, each with their own gate bays. These 18 gates today are the ones that were completed in 1955 along with the rest of the dam. Of the eighteen gates, four of them have had their coating system replaced. This protects the gates from a faster rate of corrosion. The other fourteen gates have the original coating.
Fish stocking is the practice of releasing fish that are artificially raised in a hatchery into a natural body of water, to supplement existing wild populations or to create a new population where previously none exists. Stocking may be done for the benefit of commercial, recreational or tribal heritage fishing, but may also be done for ecological conservation to restore or increase the population of threatened/endangered fish species that is pressured by prior overfishing, habitat destruction, and/or competition from invasive species.
Silvio O. Conte National Fish and Wildlife Refuge was established in 1997 to conserve, protect and enhance the abundance and diversity of native plant, fish and wildlife species and the ecosystems on which they depend throughout the 7,200,000-acre (29,000 km2) Connecticut River watershed. The watershed covers large areas of Vermont, New Hampshire, Massachusetts and Connecticut. It contains a great diversity of habitats, notably: northern forest valuable as nesting habitat for migrant thrushes, warblers and other birds; rivers and streams used by shad, salmon, herring, the endangered shortnose sturgeon and other migratory fishes; and an internationally significant complex of high-quality tidal fresh, brackish and salt marshes.
Whittlesey Creek National Wildlife Refuge is part of a large wetland complex on Lake Superior, near Ashland, Wisconsin. These coastal wetlands are a significant part of the wildlife habitat and aquatic resources of the south shore of Lake Superior.
White Sulphur Springs National Fish Hatchery is a U.S. Fish and Wildlife Service facility located along the historic Midland Trail in the Allegheny Highlands of southeast West Virginia. Established in 1900 or 1902 to produce fish for the American public, the fish hatchery became part of the National Broadstock Program in 1976. In 1995, a freshwater mussel conservation program was added.
The Little Kern golden trout is a brightly colored subspecies of rainbow trout native to the main stem and tributaries of the Little Kern River in Tulare County, California. Together with the California golden trout and the Kern River rainbow trout, the Little Kern golden trout forms what is sometimes referred to as the "golden trout complex" of the Kern River basin.
Saratoga National Fish Hatchery is part of the National Fish Hatchery System operated by the United States Fish and Wildlife Service. It is located northeast of Saratoga, Wyoming and, along with the Jackson National Fish Hatchery, is one of two National fish hatcheries operating in Wyoming. Saratoga NHF is primarily a broodstock hatchery; it maintains several healthy adults to produce sperm and eggs and distributes fertilized eggs to production hatcheries throughout the country to be hatched and grown to stockable sizes. It is also one of several organizations to establish a program for breeding Wyoming toads.
