The Broughton Archipelago is a group of islands on the northeastern flank of the Queen Charlotte Strait on the coast of British Columbia, Canada. The largest islands in the group, which includes numerous smaller islets, are Broughton Island, North Broughton Island, Eden Island, Bonwick Island and Baker Island. The islands are all located within the Regional District of Mount Waddington; however, nearly all lands in the area are owned by the Provincial Crown and most settlements in the area, with the exclusion of floating settlements, are either Indian Reserves of bands of the Musgamagw Tsawataineuk Tribal Council or fish farms under the jurisdiction of the federal Department of Fisheries and Oceans.
Queen Charlotte Strait is a strait between Vancouver Island and the Mainland of British Columbia, Canada. It connects Queen Charlotte Sound with Johnstone Strait and Discovery Passage and via them to the Strait of Georgia and Puget Sound. It forms part of the Inside Passage from Washington to Alaska. The term Queen Charlotte Strait is also used to refer to the general region and its many communities, notably of the Kwakwaka'wakw peoples. Despite its name, Queen Charlotte Strait does not lie between Haida Gwaii and the mainland; that body of water is named Hecate Strait.
The British Columbia Coast or BC Coast is Canada's western continental coastline on the North Pacific Ocean. The usage is synonymous with the term West Coast of Canada.
Broughton Island is an island in the Broughton Archipelago of the Queen Charlotte Strait area of the Central Coast of British Columbia, located northwest of Gilford Island. \
The archipelago is the traditional territory of the Kwicksutaineuk-ah-kwa-mish and Tsawataineuk subgroups of the Kwakwaka'wakw peoples and is the focus of controversy over commercial fish-farming by Norwegian aquaculture companies. One of the most prominent studies carried out to assess the relationship between fish farms and sea lice infestations on wild species was carried out in this archipelago in the spring of 2002.
Aquaculture, also known as aquafarming, is the farming of fish, crustaceans, molluscs, aquatic plants, algae, and other organisms. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. Mariculture refers to aquaculture practiced in marine environments and in underwater habitats.
A sea louse, not to be confused with sea fleas, is a member of a family of copepods within the order Siphonostomatoida, family Caligidae. There are roughly 559 species in 37 genera include around 162 Lepeophtheirus and 268 Caligus species. Sea lice are marine ectoparasites that feed on the mucus, epidermal tissue, and blood of host marine fish.
Broughton Archipelago was named in 1792 by George Vancouver in honor of William Robert Broughton, the captain of the expedition's second ship, HMS Chatham.
Captain George Vancouver was a British officer of the Royal Navy, best known for his 1791–95 expedition, which explored and charted North America's northwestern Pacific Coast regions, including the coasts of contemporary British Columbia, Canada and Alaska, Washington, and Oregon, United States. He also explored the Hawaiian Islands and the southwest coast of Australia.
William Robert Broughton was a British naval officer in the late 18th century. As a lieutenant in the Royal Navy, he commanded HMS Chatham as part of the Vancouver Expedition, a voyage of exploration through the Pacific Ocean led by Captain George Vancouver in the early 1790s.
HMS Chatham was a Royal Navy survey brig that accompanied HMS Discovery on George Vancouver's exploration of the west coast of North America in his 1791–1795 expedition. Chatham was built by King, of Dover and launched in early 1788. She was purchased for navy service on 12 February 1788.
Salmon is the common name for several species of ray-finned fish in the family Salmonidae. Other fish in the same family include trout, char, grayling and whitefish. Salmon are native to tributaries of the North Atlantic and Pacific Ocean. Many species of salmon have been introduced into non-native environments such as the Great Lakes of North America and Patagonia in South America. Salmon are intensively farmed in many parts of the world.
Fish farming or pisciculture involves raising fish commercially in tanks or enclosures such as fish ponds, usually for food. It is the principal form of aquaculture, while other methods may fall under mariculture. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species produced in fish farming are carp, tilapia, salmon, and catfish.
The Galápagos Islands, part of the Republic of Ecuador, are an archipelago of volcanic islands distributed on either side of the equator in the Pacific Ocean surrounding the centre of the Western Hemisphere, 906 km (563 mi) west of continental Ecuador. The islands are known for their large number of endemic species and were studied by Charles Darwin during the second voyage of HMS Beagle. His observations and collections contributed to the inception of Darwin's theory of evolution by means of natural selection.
The Kornati archipelago of Croatia, also known as the Stomorski islands, is located in the northern part of Dalmatia, south from Zadar and west from Šibenik, in the Šibenik-Knin county. With 35 kilometres length and 89 islands, some large, some small, in a sea area of about 320 square kilometres (124 sq mi), the Kornati are the densest archipelago in the Mediterranean Sea. From northwest to southeast, and from northeast to southwest they stretch for 13 km. The name of the archipelago is the plural form of the name of the largest island, called Kornat.
Franz Josef Land, Franz Joseph Land or Francis Joseph's Land is a Russian archipelago, inhabited only by military personnel, located in the Arctic Ocean and constituting the northernmost part of Arkhangelsk Oblast. It consists of 191 islands, which cover an area of 16,134 square kilometers (6,229 sq mi), stretching 375 kilometers (233 mi) from east to west and 234 kilometers (145 mi) from north to south. The islands are categorized in three groups, a western, central and eastern, separated by the British Channel and the Austrian Strait. The central group is further divided into a northern and southern section by the Markham Strait. The largest island is Prince George Land, which measures 2,741 square kilometers (1,058 sq mi), followed by Wilczek Land, Graham Bell Island and Alexandra Land.
The Archipelago Sea is a part of the Baltic Sea between the Gulf of Bothnia, the Gulf of Finland and the Sea of Åland, within Finnish territorial waters. By some definitions it contains the largest archipelago in the world by the number of islands, although many of the islands are very small and tightly clustered.
Archipelago National Park is a national park in Southwest Finland. It was established in 1983 and covers 500 square kilometres (193 sq mi) of land areas, a huge land area considering that the area mostly is outer archipelago with few islands even 1 km2 - and the big ones are inhabited and mostly privately owned and thus not part of the national park. The park's web pages give that number as non-qualified "area". It is part of the UNESCO biosphere reserves and received a PAN Parks certificate in 2007.
Žirje is an island and a settlement in the Croatian part of the Adriatic Sea. It is situated in the Šibenik archipelago, about 22 kilometres southwest of Šibenik, which makes it the most remote permanently inhabited island in the Šibenik archipelago. Its area is 15.08 km2, and it has a population of 103. Its population is steadily decreasing.
The Musgamagw Tsawataineuk is a First Nations tribal council based in the Queen Charlotte Strait region around northern Vancouver Island in British Columbia, Canada.
The Tsawataineuk First Nation is a First Nations band government in the Queen Charlotte Strait region north of northern Vancouver Island in the Canadian province of British Columbia. It is a member of the Musgamagw Tsawataineuk Tribal Council, along with the ‘Namgis First Nation and the Kwicksutaineuk-ah-kwa-mish First Nation.
The salmon louse, Lepeophtheirus salmonis, is a species of copepod in the genus Lepeophtheirus. It is a sea louse, a parasite living mostly on salmon, particularly on Pacific and Atlantic salmon and sea trout, but is also sometimes found on the three-spined stickleback. It lives off the mucus, skin and blood of the fish. They are natural marine parasites of fish such as adult salmon. Once detached they can be blown by wind across the surface of the sea, like plankton. When they encounter a suitable marine fish host they may adhere themselves to the skin, fins, the gills of the fish, and feeding off the mucus or skin. Sea lice only affect fish and are not harmful towards humans.
The aquaculture of salmonids is the farming and harvesting of salmonids under controlled conditions for both commercial and recreational purposes. Salmonids, along with carp, and tilapia are the three most important fish species in aquaculture. The most commonly commercially farmed salmonid is the Atlantic salmon. In the U.S. Chinook salmon and rainbow trout are the most commonly farmed salmonids for recreational and subsistence fishing through the National Fish Hatchery System. In Europe, brown trout are the most commonly reared fish for recreational restocking. Commonly farmed nonsalmonid fish groups include tilapia, catfish, sea bass, and bream.
The Gwawaenuk Tribe, or Gwawaʼenux̱w is a First Nations band government of the Kwakwaka'wakw people located in the Queen Charlotte Strait region of the Central Coast region of British Columbia, Canada. The Gwawaenuk Tribe has no year-round road access to a service centre and being about 160 km to 240 km from the nearest service centre.
Like humans and other animals, fish suffer from diseases and parasites. Fish defences against disease are specific and non-specific. Non-specific defences include skin and scales, as well as the mucus layer secreted by the epidermis that traps microorganisms and inhibits their growth. If pathogens breach these defences, fish can develop inflammatory responses that increase the flow of blood to infected areas and deliver white blood cells that attempt to destroy the pathogens.
Alexandra Bryant Hubbard Morton is a Canadian American marine biologist best known for her 30-year study of wild killer whales in the Broughton Archipelago in British Columbia. Since the 1990s, her work has shifted toward the study of the impact of salmon farming on Canadian wild salmon.
Salmon population levels are of concern in the Atlantic and in some parts of the Pacific. Salmon fishery stocks are still abundant, and catches have been on the rise in recent decades, after the state initiated limitations in 1972. Some of the most important Alaskan salmon sustainable wild fisheries are located near the Kenai River, Copper River, and in Bristol Bay. Fish farming of Pacific salmon is outlawed in the United States Exclusive Economic Zone, however, there is a substantial network of publicly funded hatcheries, and the State of Alaska's fisheries management system is viewed as a leader in the management of wild fish stocks. In Canada, returning Skeena River wild salmon support commercial, subsistence and recreational fisheries, as well as the area's diverse wildlife on the coast and around communities hundreds of miles inland in the watershed. The status of wild salmon in Washington is mixed. Out of 435 wild stocks of salmon and steelhead, only 187 of them were classified as healthy; 113 had an unknown status, 1 was extinct, 12 were in critical condition and 122 were experiencing depressed populations.
