125-719: Clayoquot Sound / ˈ k l ɑː k w ɒ t / is located on the west coast of Vancouver Island in the Canadian province of British Columbia . It is bordered by the Esowista Peninsula to the south, and the Hesquiaht Peninsula to the North. It is a body of water with many inlets and islands. Major inlets include Sydney Inlet, Shelter Inlet, Herbert Inlet, Bedwell Inlet, Lemmens Inlet, and Tofino Inlet. Major islands include Flores Island , Vargas Island, and Meares Island . The name
250-501: A common ancestor . The Eocene salmon's fossil from British Columbia provides evidence that the divergence between Pacific and Atlantic salmon had not yet occurred 40 million years ago. Both the fossil record and analysis of mitochondrial DNA suggest the divergence occurred 10 to 20 million years ago during the Miocene . This independent evidence from DNA analysis and the fossil record indicate that salmon divergence occurred long before
375-758: A $ 12M monetary fund to "support research, education and training in the Biosphere region". At the end of July 2006, a new set of Watershed Plans was approved for Clayoquot Sound. This enabled logging in some 10,000 hectares (25,000 acres) of the forest, including pristine old-growth valleys. As of 2007, both logging tenures within Clayoquot Sound are controlled by aboriginal-owned logging companies Iisaak Forest Resources controls Timber Forest License (TFL) 57 in Clayoquot Sound, and MaMook Natural Resources Ltd, in conjunction with Coulson Forest Products, manages TFL54 in Clayoquot Sound.

500-442: A few species of salmon remain in fresh water throughout their life cycle, the majority are anadromous and migrate to the ocean for maturation: in these species, smolts spend a portion of their out-migration time in brackish water, where their body chemistry becomes accustomed to osmoregulation in the ocean. This body chemistry change is hormone-driven, causing physiological adjustments in the function of osmoregulatory organs such as
625-473: A fish returns after just one year's sea feeding, it is called a grilse in Canada, Britain, and Ireland. Grilse may be present at spawning, and go unnoticed by large males, releasing their own sperm on the eggs. Prior to spawning, depending on the species , salmon undergo changes. They may grow a hump, develop canine-like teeth, or develop a kype (a pronounced curvature of the jaws in male salmon). All change from
750-569: A high demand for wild forage fish . As a predator, salmon require large nutritional intakes of protein , and farmed salmon consume more fish than they generate as a final product. On a dry weight basis, 2–4 kg of wild-caught fish are needed to produce one kilogram of salmon. As the salmon farming industry expands, it requires more forage fish for feed, at a time when 75% of the world's monitored fisheries are already near to or have exceeded their maximum sustainable yield . The industrial-scale extraction of wild forage fish for salmon farming affects
875-556: A homestead in Sooke . Following the brief governorship of Richard Blanshard , James Douglas , Chief Factor of the Hudson's Bay post, assumed the role in 1851. The island's first legislative assembly was formed in 1856. Government buildings were built and were occupied in 1859; the replacement, today's Parliament Buildings , were opened in 1898. Fort Victoria had become an important base when prospectors, miners and merchants began arriving for
1000-532: A lot of work on Henneguya salminicola was done by scientists at the Pacific Biological Station in Nanaimo in the mid-1980s, in particular, an overview report which states, "the fish that have the longest fresh water residence time as juveniles have the most noticeable infections. Hence in order of prevalence , coho are most infected followed by sockeye, chinook, chum and pink. As well, the report says, at
1125-457: A major area for recreation. The northern, western, and most of the central portions of the island are home to the coniferous "big trees" associated with British Columbia's coast – western hemlock , western red cedar , Pacific silver fir , yellow cedar , Douglas fir , grand fir , Sitka spruce , and western white pine . It is also characterised by bigleaf maple , red alder , sword fern , and red huckleberry . The fauna of Vancouver Island
1250-412: A technically demanding kind of sport fishing , not necessarily intuitive for beginning fishermen. A conflict exists between commercial fishermen and recreational fishermen for the right to salmon stock resources . Commercial fishing in estuaries and coastal areas is often restricted so enough salmon can return to their natal rivers where they can spawn and be available for sport fishing. On parts of

Other commonly cultured fish species include tilapia , catfish , sea bass , carp and bream . Salmon farming is significant in Chile , Norway , Scotland , Canada and the Faroe Islands ; it is the source for most salmon consumed in the United States and Europe. Atlantic salmon are also, in very small volumes, farmed in Russia and Tasmania , Australia. Salmon are carnivorous , and need to be fed meals produced from catching other wild forage fish and other marine organisms. Salmon farming leads to
1625-510: Is also used for the larger region of land around the waterbody (essentially its watershed). The name Clayoquot is derived from the name of a subgroup of the Nuu-chah-nulth, who lived at Clayoqua . In the late 20th century, this group merged into the multi-group band government known as the Tla-o-qui-aht , meaning "different" or "changing" in their language. First Nations have inhabited

The island is 456 km (283 mi) in length, 100 km (62 mi) in width at its widest point, and 32,100 km (12,400 sq mi) in total area, while 31,285 km (12,079 sq mi) are of land. The island is the largest by area and the most populous along the west coasts of
1875-527: Is considered invasive for its voracious appetite and scaring away of the Douglas squirrels. The island has the most concentrated population of cougars in North America. The Vancouver Island wolf , a subspecies of grey wolf , is found only on the north part of the island. Harbour seals and river otters are common. Resident orcas live in two major groups, one in the waters of the south island and one in
2000-474: Is now spoken by less than 5% of the population—about 250 people. Today, 17 separate tribes make up the Kwakwakaʼwakw. Some Kwakwakaʼwakw groups are now extinct. Kwakʼwala is a Northern Wakashan language , a grouping shared with Haisla, Heiltsuk and Wuikyala. Kwakwakaʼwakw centres of population on Vancouver Island include communities such as Fort Rupert , Alert Bay and Quatsino , the Kwakwakaʼwakw tradition of
2125-480: Is part of a group of peaks that include the only glaciers on the island, the largest of which is the Comox Glacier . The west coast shoreline is rugged and in many places mountainous, characterized by its many fjords , bays, and inlets. The interior of the island has many lakes ( Kennedy Lake , north of Ucluelet , is the largest) and rivers. The 49th parallel north crosses the island just north of Ladysmith on
2250-772: Is phasing out salmon farms by 2022 in the Discovery Islands on Vancouver Island's east side. The members of three major First Nations band governments of the Nuu-chah-nulth peoples inhabit the Clayoquot Sound: the Hesquiaht in the North, the Ahousaht in the middle, and the Tla-o-qui-aht in the south. The latter group is based in the village of Opitsaht on Meares Island . The village of Tofino lies opposite Opitsaht on
2375-441: Is quite high (perhaps as high as 40 to 50%). To lay her roe , the female salmon uses her tail (caudal fin), to create a low-pressure zone, lifting gravel to be swept downstream, excavating a shallow depression, called a redd. The redd may sometimes contain 5,000 eggs covering 2.8 m (30 sq ft). The eggs usually range from orange to red. One or more males approach the female in her redd, depositing sperm, or milt, over
2500-494: Is separated from the mainland of British Columbia by Johnstone Strait and Queen Charlotte Strait on the north and northeast, and by the Strait of Georgia on the southeast, which along with the Strait of Juan de Fuca along its southwest separate it from the United States. West of the island is the open Pacific Ocean, while to its north is Queen Charlotte Sound . The Straits of Georgia and Juan de Fuca are now officially part of
2625-447: Is similar to that found on the mainland coast, with some notable exceptions and additions. For example, mountain goats , moose , coyotes , porcupines , skunks , chipmunks , and numerous species of small mammals, while plentiful on the mainland, are absent from Vancouver Island. Grizzly bears are absent from the island, where black bears are prevalent, but in 2016, a pair of grizzlies were sighted swimming between smaller islands off

#17328372509972750-946: Is strictly a fish parasite that cannot live in or affect warm blooded animals, including man". According to Klaus Schallie, Molluscan Shellfish Program Specialist with the Canadian Food Inspection Agency , " Henneguya salminicola is found in southern B.C. also and in all species of salmon. I have previously examined smoked chum salmon sides that were riddled with cysts and some sockeye runs in Barkley Sound (southern B.C., west coast of Vancouver Island ) are noted for their high incidence of infestation." Sea lice , particularly Lepeophtheirus salmonis and various Caligus species, including C. clemensi and C. rogercresseyi , can cause deadly infestations of both farm-grown and wild salmon. Sea lice are ectoparasites which feed on mucus, blood, and skin, and migrate and latch onto
2875-474: Is the extension of summer dryness to latitudes as high as 50 °N . Only in the extreme north of the island near Port Hardy is the rainfall of the driest summer month as much as one fifth that of the wettest months from November to March. West coasts of other continents at similar latitudes have a practically even distribution of rainfall throughout the year. Vancouver Island is mostly made up of volcanic and sedimentary rock which were formed offshore on
3000-476: Is under development in Alaska . There, the young salmon are released into the ocean far from any wild salmon streams. When it is time for them to spawn, they return to where they were released, where fishermen can catch them. An alternative method to hatcheries is to use spawning channels. These are artificial streams , usually parallel to an existing stream, with concrete or rip-rap sides and gravel bottoms. Water from
3125-474: The Americas . The southern part of Vancouver Island and some of the nearby Gulf Islands are the only parts of British Columbia or Western Canada to lie south of the 49th parallel . The southeast part of the island has one of the warmest climates in Canada, and since the mid-1990s has been mild enough in a few areas to grow Mediterranean crops such as olives and lemons . The population of Vancouver Island

The genus Oncorhynchus contains 12 recognised species which occur naturally only in the North Pacific, six of which are known as Pacific salmon while the remainder are considered trout. Outside their native habitats, Chinook salmon have been successfully introduced in New Zealand and Patagonia , while coho , sockeye and Atlantic salmon have been established in Patagonia, as well. Both

Negative consequences to this sort of population manipulation include genetic "dilution" of the wild stocks. Many jurisdictions are now beginning to discourage supplemental fish planting in favour of harvest controls, and habitat improvement and protection. A variant method of fish stocking , called ocean ranching,
3500-618: The Farallon Plate , the Juan de Fuca Plate , are now subducting below the island. This process has led to Vancouver Island being one of the most seismically active regions in Canada. The subduction zone off the coast of the island forms a section of the Ring of Fire . The area has been known to host megathrust earthquakes in the past, the last being the Cascadia earthquake of 1700 . The Forbidden Plateau , in
3625-475: The Fraser Canyon Gold Rush in 1858. The Hudson's Bay lease expired in 1859 and the island reverted to Great Britain. The burgeoning town was incorporated as Victoria in 1862. Victoria became the capital of the colony of Vancouver Island, retaining this status when the island was amalgamated with the mainland in 1866. A British naval base, including Esquimalt Royal Navy Dockyard and a naval hospital,
3750-553: The Great Lakes of North America , Patagonia in South America and South Island of New Zealand . The Modern English term salmon is derived from Middle English : samoun , samon and saumon , which in turn are from Anglo-Norman : saumon , from Old French : saumon , and from Latin : salmō (which in turn might have originated from salire , meaning "to leap". ). The unpronounced "l" absent from Middle English

The migration of salmon represent a massive retrograde nutrient transfer, rich in nitrogen , sulfur , carbon and phosphorus , from the ocean to the inland freshwater ecosystems . Predation by piscivorous land animals (such as ospreys , bears and otters ) along the journey serve to transfer the nutrients from the water to land, and decomposition of salmon carcass benefits
4625-456: The Pacific coast of Canada , the louse-induced mortality of pink salmon in some regions is commonly over 80%. The risk of injury caused by underwater pile driving has been studied by Dr. Halvorsen and her co-workers. The study concluded that the fish are at risk of injury if the cumulative sound exposure level exceeds 210 dB relative to 1 μPa s. As can be seen from the production chart at

5250-497: The forest ecosystem . In the case of Pacific salmon , most (if not all) of the salmon that survive to reach the headwater spawning grounds will die after laying eggs and their dead bodies sink to cover the gravel beds, with the nutrients released from the biodegradation of their corpses providing a significant boost to these otherwise biomass -poor shallow streams. Grizzly bears function as ecosystem engineers , capturing salmon and carrying them into adjacent dry land to eat

In 1791, the complex inner waters were explored and mapped by José María Narváez and Juan Carrasco ; their commander, Francisco de Eliza , met and befriended Wickaninnish , the chief of the Tla-o-qui-aht peoples. These explorers recognized the region's wealth of natural resources. These resources attracted growing numbers of non-First Nations peoples, who limited First Nation access to land, and generated resentment among

A highly contagious virus variant found in Norwegian salmon farms has been found in Clayoquot Sound farmed salmon. Environmental advocacy organizations have stated such events are evidence of the environmental damage associated with this type of fish farming. The British Columbia provincial government has closed other salmon farming sites on Vancouver Island. For instance, it
5625-524: The myrtle zone . These dams can be overtopped at high tide and hold water at low tide. This provides refuges for juvenile salmon so they do not have to swim into large channels where they are subject to predation by larger fish. It has been discovered that rivers which have seen a decline or disappearance of anadromous lampreys , loss of the lampreys also affects the salmon in a negative way. Like salmon, anadromous lampreys stop feeding and die after spawning, and their decomposing bodies release nutrients into

However, populations of several species are restricted to fresh waters (i.e. landlocked) throughout their lives. Folklore has it that the fish return to the exact stream where they themselves hatched to spawn , and tracking studies have shown this to be mostly true. A portion of a returning salmon run may stray and spawn in different freshwater systems;
5875-590: The otolith (annuli), analogous to the growth rings visible in a tree trunk. Freshwater growth shows as densely crowded rings, sea growth as widely spaced rings; spawning is marked by significant erosion as body mass is converted into eggs and milt. Freshwater streams and estuaries provide important habitat for many salmon species. They feed on terrestrial and aquatic insects , amphipods , and other crustaceans while young, and primarily on other fish when older. Eggs are laid in deeper water with larger gravel and need cool water and good water flow (to supply oxygen) to

#17328372509977750-608: The common name "salmon" simply due to similar shapes, behaviors and niches occupied: Salmon eggs are laid in freshwater streams typically at high latitudes. The eggs hatch into alevin or sac fry. The fry quickly develop into parr with camouflaging vertical stripes. The parr stay for six months to three years in their natal stream before becoming smolts, which are distinguished by their bright, silvery colour with scales that are easily rubbed off. Only 10% of all salmon eggs are estimated to survive to this stage. The smolt body chemistry changes, allowing them to live in salt water. While

Salmon are mid- level carnivores whose diet change according to their life stage. Salmon fry predominantly feed upon zooplanktons until they reach fingerling sizes, when they start to consume more aquatic invertebrates such as insect larvae , micro crustaceans and worms . As juveniles (parrs), they become more predatory and actively prey upon aquatic insects , small crustaceans, tadpoles and small bait fishes . They are also known to breach

Bears preparing for hibernation tend to preferentially consume the more nutrient- and energy -rich salmon roes and brain over the actual flesh , and are estimated to discard up to half the salmon they've harvested uneaten on the forest floor, in densities that can reach 4,000 kg (8,800 lb) per hectare, providing as much as 24% of
9250-566: The gills, which leads to large increases in their ability to secrete salt. Hormones involved in increasing salinity tolerance include insulin-like growth factor I , cortisol , and thyroid hormones , which permits the fish to endure the transition from a freshwater environment to the ocean. The salmon spend about one to five years (depending on the species) in the open ocean, where they gradually become sexually mature. The adult salmon then return primarily to their natal streams to spawn. Atlantic salmon spend between one and four years at sea. When
9375-672: The island in 1774 when rumours of Russian fur traders caused Spain to send a number of expeditions to assert its long-held claims to the Pacific Northwest . The first expedition was that of the Santiago , under the command of Juan José Pérez Hernández . In 1775, a second Spanish expedition under the Spanish Peruvian captain Juan Francisco de la Bodega y Quadra was sent. By 1776, Spanish exploration had reached Bucareli Bay including
9500-505: The island remained in dispute between the Kingdom of Great Britain and the Spanish Empire in the early 1790s. The two countries nearly began a war over the issue; the confrontation became known as the Nootka Crisis . That was averted when both agreed to recognize the other's rights to the area in the first Nootka Convention in 1790, a first step to peace. Finally, the two countries signed
9625-519: The island's west coast expanded from Cape Scott in the north to Barkley Sound to the south. The majority of Vancouver Island's population lives in the Capital Regional District , more specifically in the primate city and the provincial capital of Victoria . With a population of 397,237 (2021), Greater Victoria is the island's largest population centre and one of its two census metropolitan areas . The island's other metropolitan area
9750-452: The island, this is characterized by Douglas fir , western red cedar , arbutus (or madrone), Garry oak , salal , Oregon grape , and manzanita ; moreover, Vancouver Island is the location where the Douglas fir was first recorded by Archibald Menzies . Vancouver Island is also the location where some of the tallest Douglas fir were recorded. This southeastern portion of the island is the most heavily populated region of Vancouver Island and
9875-520: The largest area of intact (unlogged) temperate rainforest left on Vancouver Island. Clayoquot Sound is home to wolves , black bears , cougars , grey whales , orcas , porpoises , seals , sea lions , river otters , bald eagles , osprey , marbled murrelets , Pacific loons , Roosevelt elk , martens , and raccoons . In 2000, Clayoquot Sound Biosphere Reserve was designated as a Biosphere Reserve by UNESCO . The designation created world recognition of Clayoquot Sound's biological diversity, and
10000-555: The late 1980s, the situation escalated when the government approved MacMillan Bloedel Corporation's permit to log Meares Island. The First Nations peoples expressed their opposition to the MacMillan Bloedel Corporation logging in the Clayoquot Sound by several peaceful protests and blockades of logging roads from 1980 to 1994. In the summer of 1993, over 800 protestors were arrested, and many were tried for interfering with approved industry. Protestors included members of
10125-681: The left, the global capture reported by different countries to the FAO of commercial wild salmon has remained fairly steady since 1990 at about one million tonnes per year. This is in contrast to farmed salmon (below) which has increased in the same period from about 0.6 million tonnes to well over two million tonnes. Nearly all captured wild salmon are Pacific salmon . The capture of wild Atlantic salmon has always been relatively small, and has declined steadily since 1990. In 2011 only 2,500 tonnes were reported. In contrast, about half of all farmed salmon are Atlantic salmon. Recreational salmon fishing can be
10250-462: The local Tla-o-qui-aht First Nation and Ahousaht First Nation bands, as well as NDP MP Svend Robinson , and environmental groups such as Greenpeace and Friends of Clayoquot Sound . International mass media covered the protests and blockades, helping to create national support for environmental movements in British Columbia and foster strong advocacy for anti-logging campaigns. Media reported
10375-473: The locals. Government support of private company resource extraction allowed for the growth of such industry over time. Logging companies were active in harvesting timber in the Clayoquot Sound area as late as the 1980s and 1990s. In the late 20th century, First Nations became more active in trying to defend their rights and resources. They developed Native lobbying organizations and insisted on negotiations regarding governmental policies about such resources. In
10500-458: The longer the fish remain in fresh water, and they then deteriorate further after they spawn, when they are known as kelts. In all species of Pacific salmon, the mature individuals die within a few days or weeks of spawning, a trait known as semelparity . Between 2 and 4% of Atlantic salmon kelts survive to spawn again, all females. However, even in those species of salmon that may survive to spawn more than once ( iteroparity ), postspawning mortality
10625-944: The more notable rivers are the Somass River in the Alberni Valley , the Nimpkish River in the North Island region, the Englishman River up island from Nanaimo near Parksville , and the Cowichan River whose basin forms the Cowichan Valley region in the South Island region. The climate of Vancouver Island is the mildest in Canada, with temperatures on the coast even in January being usually above 0 °C (32 °F). In summer,
10750-515: The mouth of the Columbia River between Oregon and Washington , and Sitka Sound . Vancouver Island came to the attention of Britain after the third voyage of Captain James Cook , who spent a month during 1778 at Nootka Sound , on the island's western coast. Cook claimed it for Great Britain. Maritime fur trader , John Meares arrived in 1786 and set up a single-building trading post near
10875-530: The naming of the city of Vancouver in 1885. By March 1843, James Douglas of the Hudson's Bay Company and a missionary had arrived and selected an area for settlement. Construction of the fort began in June of that year. This settlement was a fur trading post originally named Fort Albert (afterward Fort Victoria ). The fort was located at the Songhees settlement of Camosack (Camosun), 200 m (660 ft) northwest of
11000-427: The native village of Yuquot (Friendly Cove), at the entrance to Nootka Sound in 1788. The fur trade began expanding into the island, eventually leading to permanent settlement. The island was further explored by Spain in 1789 with Esteban José Martínez , who established the settlement of Yuquot and the artillery battery of Fort San Miguel at Friendly Cove , which Spain called Puerto de San Lorenzo de Nuca. This
11125-527: The natural resources abundant in the area. The Kwakwakaʼwakw today number about 5,500, who live in British Columbia on northern Vancouver Island and the mainland. They are also known as Kwakiutl in English, from one of their tribes, but they prefer their autonym Kwakwakaʼwakw . Their indigenous language, part of the Wakashan family, is Kwakʼwala . The name Kwakwakaʼwakw means "speakers of Kwakʼwala". The language
11250-581: The north , while a third group of transient orcas roam much farther and avoid the resident orcas. Residents are watched from a distance and are numbered, with many being named as well. Humpback whales and gray whales are often seen on their migration between Alaskan waters where they feed in the summer and southern waters such as around California and Mexico where they give birth in the winter. The island's rivers, lakes, and coastal regions are renowned for their fisheries of trout , salmon , and steelhead . After near-total extirpation by fur traders in
11375-533: The now disappeared Kula oceanic plate . Around 55 million years ago during the Paleogene Period , a microplate of the Kula Plate subducted below the North American continental margin with great strain. A volcanic arc on the surface of the Kula Plate was thus accreted and fused onto the western edge of North America. These terranes were subjected to extreme warping from continued subduction of
11500-446: The parasitic infection into a number of cysts that contain milky fluid. This fluid is an accumulation of a large number of parasites. Henneguya and other parasites in the myxosporean group have complex life cycles, where the salmon is one of two hosts. The fish releases the spores after spawning. In the Henneguya case, the spores enter a second host, most likely an invertebrate, in the spawning stream. When juvenile salmon migrate to
11625-431: The perceived injustice of numerous individuals being arrested for joining peaceful protests and blockades. In some cases, law enforcement responded aggressively, which eventually helped strengthen public support for non-violent protests. After the 1990 protests, the provincial government made its first significant change in policy. It commissioned a scientific panel to examine issues related to Clayoquot Sound. In July 1995,
11750-525: The percent of straying depends on the species of salmon. Homing behavior has been shown to depend on olfactory memory . Salmon are important food fish and are intensively farmed in many parts of the world, with Norway being the world's largest producer of farmed salmon, followed by Chile . They are also highly prized game fish for recreational fishing , by both freshwater and saltwater anglers . Many species of salmon have since been introduced and naturalized into non-native environments such as
11875-584: The period. But as Spanish interests in the region dwindled, so did the use of Bodega y Quadra's name. The Hudson's Bay Company played a major part in the transition; by 1824 'Vancouver's Island' had become the usual designation in its correspondence for the island. A quarter of a century later, Vancouver Island had become such a well-known geographical feature that the founding of the Colony of Vancouver Island in 1849 gave this name full official status. Period references to "Vancouver" referred to Vancouver Island until
12000-517: The preferred prey of seals and sea lions, which can eat 30 lampreys to every salmon, allowing more adult salmon to enter the rivers to spawn without being eaten by the marine mammals. According to Canadian biologist Dorothy Kieser, the myxozoan parasite Henneguya salminicola is commonly found in the flesh of salmonids. It has been recorded in the field samples of salmon returning to the Haida Gwaii Islands . The fish responds by walling off
12125-565: The present-day Empress Hotel on Victoria's Inner Harbour . In 1846, the Oregon Treaty , which ended the Oregon boundary dispute , was signed by the British and the United States to settle the question of the U.S. Oregon Country borders. The Treaty made the 49th parallel latitude north the official border between the two countries. In order to ensure that Britain retained all of Vancouver Island and
12250-408: The problems of rising costs for buying hatchery fish feed . Yet another attractive alternative is the increased use of seaweed . Seaweed provides essential minerals and vitamins for growing organisms. It offers the advantage of providing natural amounts of dietary fiber and having a lower glycemic load than grain-based fish meal . In the best-case scenario, widespread use of seaweed could yield
12375-598: The provincial government and Nuu-chah-nulth first nations signing the Interim Measures Act (IMA) on March 19, 1994. (This followed protests in 1993 that gained international coverage on this issue, increasing the pressure.) Since the IMA was signed, the First Nations and government have negotiated to co-manage local land and resources, including economic development strategies. With the reduction in logging in this area, in
12500-466: The regular streams. Spawning channels preserve the natural selection of natural streams, as there is no benefit, as in hatcheries, to use prophylactic chemicals to control diseases. Farm-raised salmon are fed the carotenoids astaxanthin and canthaxanthin to match their flesh colour to wild salmon to improve their marketability. Wild salmon get these carotenoids , primarily astaxanthin, from eating shellfish and krill . One proposed alternative to
12625-407: The roe. The female then covers the eggs by disturbing the gravel at the upstream edge of the depression before moving on to make another redd. The female may make as many as seven redds before her supply of eggs is exhausted. Each year, the fish experiences a period of rapid growth, often in summer, and one of slower growth, normally in winter. This results in ring formation around an earbone called
12750-503: The salmon population. This system is referred to as ranching . It was very common in countries such as Sweden, before the Norwegians developed salmon farming, but is seldom done by private companies. As anyone may catch the salmon when they return to spawn, a company is limited in benefiting financially from their investment. Because of this, the ranching method has mainly been used by various public authorities and non-profit groups, such as
12875-484: The second Nootka Convention in 1793 and the third Convention in 1794. As per that final agreement, the Spanish dismantled their fort at Nootka and left the area, giving the British sovereignty over Vancouver Island and the adjoining islands (including the Gulf Islands ). For decades, Quadra's and Vancouver's Island was the most prominent name on maps of the coast, and appeared on most British, French and Spanish maps of
13000-421: The silvery blue of a fresh-run fish from the sea to a darker colour. Salmon can make amazing journeys, sometimes moving hundreds of miles upstream against strong currents and rapids to reproduce. Chinook and sockeye salmon from central Idaho, for example, travel over 1,400 km (900 mi) and climb nearly 2,100 m (7,000 ft) from the Pacific Ocean as they return to spawn. Condition tends to deteriorate
13125-546: The skin of wild salmon during free-swimming, planktonic nauplii and copepodid larval stages, which can persist for several days. Large numbers of highly populated, open-net salmon farms can create exceptionally large concentrations of sea lice; when exposed in river estuaries containing large numbers of open-net farms, many young wild salmon are infected, and do not survive as a result. Adult salmon may survive otherwise critical numbers of sea lice, but small, thin-skinned juvenile salmon migrating to sea are highly vulnerable. On
13250-487: The southern Gulf Islands, however, it was agreed that the border would swing south around that area. In 1849, the Colony of Vancouver Island was established. The Colony was leased to the Hudson's Bay Company (HBC) for an annual fee of seven shillings; the company's responsibility in return was to increase the population by promoting colonization. The first independent settler arrived that year: Captain Walter Grant started
13375-483: The southern promontory of the entrance to the sound. In 1985, for the first time in British Columbia history, the courts froze resource development on crown land because of a related Aboriginal title claim. Chiefs of the Ahousaht and Tla-o-qui-aht first nations obtained an injunction halting logging on Meares Island in Clayoquot Sound pending treaty negotiations with the provincial government. These negotiations resulted in
13500-491: The southernmost harbours frequented by American fur traders at 51 degrees north and 128 degrees west . He relates that since Captain Robert Gray of Tiverton, Rhode Island , had sailed the Columbia River in 1792, the trade of the northwest coast had been almost entirely in the hands of Boston merchants, so much so that the natives called all traders "Boston Men". A settlement was not successfully negotiated and ownership of
13625-458: The stream. Also, along with species like rainbow trout and Sacramento sucker , lampreys clean the gravel in the rivers during spawning. Their larvae, called ammocoetes, are filter feeders which contribute to the health of the waters. They are also a food source for the young salmon, and being fattier and oilier, it is assumed predators prefer them over salmon offspring, taking off some of the predation pressure on smolts. Adult lampreys are also
13750-534: The survivability of other wild predatory fish which rely on them for food. Research is ongoing into sustainable and plant-based salmon feeds. Intensive salmon farming uses open-net cages, which have low production costs. It has the drawback of allowing disease and sea lice to spread to local wild salmon stocks. Another form of salmon production, which is safer but less controllable, is to raise salmon in hatcheries until they are old enough to become independent. They are released into rivers in an attempt to increase
13875-429: The time the studies were conducted, stocks from the middle and upper reaches of large river systems in British Columbia such as Fraser , Skeena , Nass and from mainland coastal streams in the southern half of B.C., "are more likely to have a low prevalence of infection." The report also states, "It should be stressed that Henneguya , economically deleterious though it is, is harmless from the view of public health . It
14000-467: The total nitrogen available to the riparian woodlands . The foliage of spruce trees up to 500 m (1,600 ft) from a stream where grizzlies fish salmon have been found to contain nitrogen originating from the fished salmon. Beavers also function as ecosystem engineers; in the process of tree-cutting and damming , beavers alter the local ecosystems extensively. Beaver ponds can provide critical habitat for juvenile salmon . An example of this
14125-597: The use of wild-caught fish as feed for the salmon, is the use of soy -based products. This should be better for the local environment of the fish farm, but producing soy beans has a high environmental cost for the producing region. The fish omega-3 fatty acid content would be reduced compared to fish-fed salmon. Another possible alternative is a yeast-based coproduct of bioethanol production, proteinaceous fermentation biomass. Substituting such products for engineered feed can result in equal (sometimes enhanced) growth in fish. With its increasing availability, this would address
14250-502: The warmest days usually have a maximum of 28–33 °C (82–91 °F). The southeastern part of the island notably has a warm summer (Csb) Mediterranean climate with numerous vineyards . The rain shadow effect of the island's mountains, as well as the mountains of Washington's Olympic Peninsula , creates wide variation in precipitation. The west coast is considerably wetter than the east coast. Average annual precipitation ranges from 6,650 mm (262 in) at Hucuktlis Lake on
14375-417: The water to attack terrestrial insects such as grasshoppers and dragonflies , as well as consuming fish eggs (even those of other salmon). As adults, salmon behave like other mid-sized pelagic fish , eating a variety of sea creatures including smaller forage fish such as lanternfish , herrings , sand lances , mackerels and barracudina . They also eat krill , squid and polychaete worms . In
14500-531: The west coast (making it the wettest place in North America) to only 608 mm (23.9 in) at Victoria Gonzales, the driest recording station in the provincial capital of Victoria . Precipitation is heaviest in the autumn and winter. Snow is rare at low altitudes, but is common on the island's mountaintops in winter. Skiing is popular at Mount Washington in the mid-island, with an elevation of 1,588 m (5,210 ft). A notable feature of Vancouver Island
14625-471: Was 864,864 as of 2021. Nearly half of that population (~400,000) live in the metropolitan area of Greater Victoria on the southern tip of the island, which includes Victoria , the capital of British Columbia. Other notable cities and towns on Vancouver Island include Nanaimo , Campbell River , Courtenay , Port Alberni and Parksville , all on or near the east coast. Indigenous peoples have inhabited Vancouver Island for thousands of years, long before
14750-549: Was Vancouver who made the suggestion of combining their names to designate some geographical feature. In 1792, the Spanish explorer Dionisio Alcalá Galiano and his crew were the first Europeans to circumnavigate Vancouver Island. On April 8, 1806, Captain John D'Wolf of Bristol, Rhode Island , sailed the Juno to Nahwitti (Newettee), a small inlet in the northwestern promontory of Vancouver's Island. The captain described Newettee as one of
14875-419: Was commandant of Santa Cruz de Nuca in 1792. Vancouver had sailed as a midshipman with Cook. The negotiations between Vancouver and Bodega y Quadra ended in a deadlock with nothing resolved. Vancouver insisted the entire Spanish establishment be turned over, but Bodega y Quadra held that there were no buildings seized in 1789, and the only possible land was a tiny and useless cove nearby. The two decided to refer
15000-678: Was completed, Greenpeace lifted the boycott. After the inventory, the government reduced the Annual Allowable Cut, and clear-cuts in the area were limited to a maximum of four hectares. In addition, once biological and cultural inventories were completed, the government required Eco-Based Planning. The sound's ecological features have made it a major site for the farming of salmon , a fish traditional to this area. Floating feedlots have been installed, consisting of giant fenced pens. There are roughly twenty such farms in operation. A massive die-off of fish, possibly linked to an algal bloom caused by
15125-634: Was established at Esquimalt in 1865 and eventually taken over by the Canadian military . Today, as CFB Esquimalt , it is the home port of the Maritime Forces Pacific and parts are designated as National Historic Sites of Canada . The economic situation of the colony declined following the Cariboo Gold Rush of 1861–1862, and pressure grew for amalgamation of the colony with the mainland colony of British Columbia (which had been established in 1858). The two colonies were merged in 1866 into
15250-501: Was eventually dropped.) It is one of several North American locations named after George Vancouver, who between 1791 and 1794 explored the Pacific Northwest . Vancouver Island is the world's 43rd largest island , Canada's 11th largest island , and Canada's second most populous island after the Island of Montreal . Vancouver Island has been the homeland of many indigenous peoples for thousands of years. The groupings, by language, are
15375-435: Was later added as a Latinisation to make the word closer to its Latin root. The term salmon has mostly displaced its now dialectal synonym lax , in turn from Middle English : lax , from Old English : leax , from Proto-Germanic : * lahsaz from Proto-Indo-European : *lakso- . The seven commercially important species of salmon occur in two genera of the subfamily Salmoninae . The genus Salmo contains
15500-571: Was seen in the years following 1818 in the Columbia River Basin. In 1818, the British government made an agreement with the U.S. government to allow U.S. citizens access to the Columbia catchment (see Treaty of 1818 ). At the time, the Hudson's Bay Company sent word to trappers to extirpate all furbearers from the area in an effort to make the area less attractive to U.S. fur traders. In response to
15625-474: Was to be the only Spanish settlement in what would later be Canada. Asserting their claim of exclusive sovereignty and navigation rights, the Spanish force seized the Portuguese-flagged British ships. British naval captain George Vancouver was sent to Nootka Sound in 1792 in order to negotiate a settlement. His Spanish counterpart in the negotiations was Juan Francisco de la Bodega y Quadra, who
