The Yukon River is a major watercourse of northwestern North America. From its source in British Columbia, Canada, it flows through Canada's territory of Yukon. The lower half of the river continues westward through the U.S. state of Alaska. The river is 3,190 kilometres (1,980 mi) long and empties into the Bering Sea at the Yukon–Kuskokwim Delta. The average flow is 6,400–7,000 m3/s (230,000–250,000 cu ft/s). The total drainage area is 833,000 km2 (321,500 sq mi), of which 323,800 km2 (125,000 sq mi) lies in Canada. The total area is more than 25% larger than Texas or Alberta.
Salmon is the common name for several commercially important species of euryhaline ray-finned fish from the genera Salmo and Oncorhynchus of the family Salmonidae, native to tributaries of the North Atlantic (Salmo) and North Pacific (Oncorhynchus) basins. Other closely related fish in the same family include trout, char, grayling, whitefish, lenok and taimen, all coldwater fish of the subarctic and cooler temperate regions with some sporadic endorheic populations in Central Asia.
The Fraser River is the longest river within British Columbia, Canada, rising at Fraser Pass near Blackrock Mountain in the Rocky Mountains and flowing for 1,375 kilometres (854 mi), into the Strait of Georgia just south of the City of Vancouver. The river's annual discharge at its mouth is 112 cubic kilometres (27 cu mi) or 3,550 cubic metres per second (125,000 cu ft/s), and each year it discharges about 20 million tons of sediment into the ocean.
The Stikine River is a major river in northern British Columbia (BC), Canada and southeastern Alaska in the United States. It drains a large, remote upland area known as the Stikine Country east of the Coast Mountains. Flowing west and south for 610 kilometres (379 mi), it empties into various straits of the Inside Passage near Wrangell, Alaska. About 90 percent of the river's length and 95 percent of its drainage basin are in Canada. Considered one of the last truly wild large rivers in BC, the Stikine flows through a variety of landscapes including boreal forest, steep canyons and wide glacial valleys.
The Chinook salmon is the largest and most valuable species of Pacific salmon. Its common name is derived from the Chinookan peoples. Other vernacular names for the species include king salmon, Quinnat salmon, Tsumen, spring salmon, chrome hog, Blackmouth, and Tyee salmon. The scientific species name is based on the Russian common name chavycha (чавыча).
The sockeye salmon, also called red salmon, kokanee salmon, blueback salmon, or simply sockeye, is an anadromous species of salmon found in the Northern Pacific Ocean and rivers discharging into it. This species is a Pacific salmon that is primarily red in hue during spawning. They can grow up to 84 cm in length and weigh 2.3 to 7 kg (5–15 lb). Juveniles remain in freshwater until they are ready to migrate to the ocean, over distances of up to 1,600 km (1,000 mi). Their diet consists primarily of zooplankton. Sockeye salmon are semelparous, dying after they spawn. Some populations, referred to as kokanee, do not migrate to the ocean and live their entire lives in fresh water.
Hells Gate is an abrupt narrowing of British Columbia's Fraser River, located immediately downstream of Boston Bar in the southern Fraser Canyon. The towering rock walls of the Fraser River plunge toward each other forcing the waters through a passage only 35 metres (115 ft) wide. It is also the name of the rural locality at the same location.
The Halibut Treaty was a 1923 Canadian–American agreement concerning fishing rights in the northern Pacific Ocean. The treaty established the International Pacific Halibut Commission (IPHC) as a mechanism for the joint management of the Pacific halibut which, at that time, was in severe decline. The commission originally had four members but now has six, which are selected from industry and related government agencies. Half the members are Canadian and half are from the United States. The treaty also had a provision for a closed season, so halibut could not be fished during the more dangerous winter months. The treaty has been revised numerous times, often based on recommendations from the IPHC and its team of scientific researchers.
A fish wheel, also known as a salmon wheel, is a device situated in rivers to catch fish which looks and operates like a watermill. However, in addition to paddles, a fish wheel is outfitted with wire baskets designed to catch and carry fish from the water and into a nearby holding tank. The current of the river presses against the submerged paddles and rotates the wheel, passing the baskets through the water where they intercept fish that are swimming or drifting. Naturally, a strong current is most effective in spinning the wheel, so fish wheels are typically situated in shallow rivers with brisk currents, close to rapids, or waterfalls. The baskets are built at an outward-facing slant with an open end so the fish slide out of the opening and into the holding tank where they await collection. Yield is increased if fish swimming upstream are channeled toward the wheel by weirs.
The Alaska salmon fishery is a managed fishery that supports the annual harvest of five species of wild Pacific Salmon for commercial fishing, sport fishing, subsistence by Alaska Native communities, and personal use by local residents. The salmon harvest in Alaska is the largest in North America and represents about 80% of the total wild-caught catch, with harvests from Canada and the Pacific Northwest representing the remainder In 2017 over 200 million salmon were caught in Alaskan waters by commercial fishers, representing $750 million in exvessel value. Salmon fishing is a nearly ubiquitous activity across Alaska, however the most valuable salmon fisheries are in the Bristol Bay, Prince William Sound and Southeast regions.
The survival of wild salmon relies heavily on them having suitable habitat for spawning and rearing of their young. This habitat is the main concern for conservationists. Salmon habitat can be degraded by many different factors including land development, timber harvest, or resource extraction. These threats bring about the traditional methods of protecting the salmon, but a new movement aims to protect the habitats before they require intervention.
The Adams River is a tributary to the Thompson and Fraser Rivers in British Columbia, Canada. Beginning in the Monashee Mountains to the north, the Upper Adams River flows mainly southward and eventually reaches Adams Lake. The Lower Adams River begins at the southern end of the lake and flows into the extreme western end of Shuswap Lake. The river is one of the most important sockeye salmon breeding areas in North America. The run occurs in mid-October and can bring millions of fish to a concentrated area near the river mouth. Excavations of Secwepemc villages on the river have shown a long tradition of habitation and salmon fishing in the area. The river also served as an important transportation route for early logging operations in the watershed.
Moran Dam, also called High Moran Dam or Moran Canyon Dam, was a 1950s proposal to dam the Fraser River in the Canadian province of British Columbia (BC). The structure was planned in the wake of devastating floods in a time of rapidly growing power demand, and if built, would have powered the largest hydroelectric facility in North America. After a protracted environmental battle, Moran Dam was defeated in 1972, mainly over concerns of its adverse impact on salmon populations in the Fraser River basin. The shelving of the project also influenced cancellation of other hydro developments along the river, and today the Fraser remains one of the most productive salmon fisheries on the continent.
A salmon cannery is a factory that commercially cans salmon. It is a fish-processing industry that became established on the Pacific coast of North America during the 19th century, and subsequently expanded to other parts of the world that had easy access to salmon.
The North Pacific Anadromous Fish Commission (NPAFC) is an international, inter-governmental organization dedicated to the conservation of anadromous fish stocks in international waters of the North Pacific Ocean and its adjacent seas. It was established on 11 February 1992 by the Convention for the Conservation of Anadromous Stocks in the North Pacific Ocean and originally consisted of four member nations: Canada, Japan, Russian Federation, and United States of America. On 27 May 2003, the Republic of Korea acceded to the Convention bringing the current number of Commission members to five. The primary objective of the Commission is to provide a mechanism for international cooperation promoting the conservation of anadromous stocks in the NPAFC Convention Area of the North Pacific Ocean.
Salmon population levels are of concern in the Atlantic and in some parts of the Pacific. Salmon are typically anadromous - they rear and grow in freshwater, migrate to the ocean to reach sexual maturity, and then return to freshwater to spawn. Determining how environmental stressors and climate change will affect these fisheries is challenging due to their lives split between fresh and saltwater. Environmental variables like warming temperatures and habitat loss are detrimental to salmon abundance and survival. Other human influenced effects on salmon like overfishing and gillnets, sea lice from farm raised salmon, and competition from hatchery released salmon have negative effects as well.
The Coast Salish people of the Canadian Pacific coast depend on salmon as a staple food source, as they have done for thousands of years. Salmon has also served as a source of wealth and trade and is deeply embedded in their culture, identity, and existence as First Nations people of Canada. Traditional fishing is deeply tied to Coast Salish culture and salmon were seen "as gift-bearing relatives, and were treated with great respect" since all living things were once people according to traditional Coast Salish beliefs. Salmon are seen by the Coast Salish peoples are beings similar to people but spiritually superior.
William Francis Thompson was an American ichthyologist and fisheries scientist.
The Pacific Salmon War was a period of heightened tensions between Canada and the United States over the Pacific Salmon catch. It began in 1992 after the first Pacific Salmon Treaty, which had been ratified in 1985, expired, and lasted until a new agreement was signed in 1999. Disagreements were high in 1994, when a transit fee was set on American fishing vessels using the Inside Passage and a ferry was blockaded by fishing boats in Friday Harbor, Washington.
The Fisheries Act is legislation enacted by the Parliament of Canada, governing the powers of government to regulate fisheries and fishing vessels. The act has been undergoing major regulatory revisions in recent years, including those attached to treaty rights of Miꞌkmaq in Atlantic Canada. The Minister designated under the Act is the Ministers of Fisheries, Oceans and the Canadian Coast Guard.
