98-456: The Lake, approached from the park area, offers one of the best red salmon fishing locations in Southeast Alaska. Salmon fishing in the lake during the spawning period is done in four runs starting with mid-June and ending in mid-October when it is also the time for Bears to frequent the lake precincts to hunt for its favorite salmons. The Chilkoot Lake's commercial fishing of Sockeye salmon

196-501: 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

294-577: A costumed person on fire during a celebration in Minsk in 1979 and sentenced to five years of imprisonment. Mathias Rust was convicted of hooliganism, among other things, for his 1987 Cessna landing on Bolshoy Moskvoretsky Bridge next to Red Square . Since the fall of the Soviet Union, nowadays, hooliganism is defined generally in the Criminal Code of Russia as an average gravity crime. More recently,

392-414: A dynamic process occurring at different levels. Macro-sociological accounts suggest that structural strains, experiences of deprivation or a low socio-economic background can at times be instrumental to the acceptance and reproduction of norms that tolerate great levels of violence and territoriality, which is a common feature of football hooliganism. Furthermore, social cleavages within societies facilitate

490-442: 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

588-473: 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

686-639: A future in aquaculture that eliminates the need for land, freshwater, or fertilizer to raise fish. Salmon population levels are of concern in the Atlantic and in some parts of the Pacific. The population of wild salmon declined markedly in recent decades, especially North Atlantic populations, which spawn in the waters of western Europe and eastern Canada, and wild salmon in the Snake and Columbia River systems in northwestern United States. Hooligan Hooliganism

784-600: A good location for spawning of red salmons. The clear water from the springs was found to be colder than the lake water but these did not provide good conditions for locating a hatchery. According to the studies carried out by the Alaska Department of Fish and Game, 25% spawn of sockeye is from the sensitive habitat of the upper watershed above the Chilkoot Lake. These studies also indicated that anadromous fish, coho, Dolly Varden, and an occasional chum salmon were found above

882-569: 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

980-532: 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

1078-408: A national hero, not by making trouble, which Mr. Malik understands is the function of a hooligan, but by getting himself help." Later, as the meaning of the word shifted slightly, none of the possible alternatives had precisely the same undertones of a person, usually young, who belongs to an informal group and commits acts of vandalism or criminal damage, starts fights, and who causes disturbances but

1176-469: A quiet gliding experience of about 1 mile (2 km), and this experience is said to be totally unlike the skating at a rink. Apart from the lake road to the lake is also used for skiing. Chilkoot Lake is considered a good water body for safe and peaceful kayaking , particularly for beginners in paddle kayaking (for learning the basic skills). The kayak launching post is the State Park at the southern end of

1274-412: 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

1372-836: Is a major contributor to the world production of farmed finfish, representing about US$ 10 billion annually. 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

1470-401: Is a popular sport in the peak of winter in the Chilkoot Lake when it gets completely frozen. During winter the lake appears bowl-shaped and is surrounded by white, snow-covered mountains, tucked in a valley and is free from icy winds. The hardness of the ice in the lake is said to be "hard and shiny as a marble floor" and reflects the dark spruce trees and mountains. The ice skating in the lake is

1568-408: Is disruptive or unlawful behavior such as rioting , bullying and vandalism , often in connection with crowds at sporting events. A hooligan is a person that engages in illicit reckless behaviors and is a public nuisance . There are several theories regarding the origin of the word hooliganism, which is a derivative of the word hooligan . The Compact Oxford English Dictionary states that

1666-489: Is not a thief. Hooliganism is now predominately related to sport. The words hooliganism and hooligan began to be associated with violence in sports , in particular from the 1970s in the UK with football hooliganism . The phenomenon, however, long preceded the modern term; for example, one of the earliest known instances of crowd violence at a sporting event took place in ancient Constantinople . Two chariot racing factions,

1764-402: Is not disturb the bears, which may be seen hunting for fish on the shore line. Salmon all other members of Salmoninae Salmon ( / ˈ s æ m ən / ; pl. : 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

1862-441: 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

1960-946: 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

2058-476: 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

2156-654: Is worth about $ 1 million annually. The Chilkoot Lake is marked on the quadrant map of the Skagway B 2 USGS in the Heines County at an altitude of 30 feet (9 m). The lake is about 3.6 miles (6 km) long, and about 1 mile (2 km) in width and maximum depth of water in the lake is about 300 feet (90 m). It is located at the foot of the Takshanuk Mountains to the west and the Freebee glacier and unnamed mountains to

2254-823: The Atlantic salmon , found in both sides of the North Atlantic , as well as more than 40 other species commonly named as trout . 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

2352-610: The Cook Inlet Aquaculture Association , as a way to increase salmon populations in situations where they have declined due to overharvesting , construction of dams and habitat destruction or fragmentation . 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,

2450-553: 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

2548-484: The Japanese word for trout. On the other hand, the steelhead and sea trout , the anadromous forms of rainbow trout and brown trout respectively, are from the same genera as salmon and live identical migratory lives, but neither is termed "salmon" . The extinct Eosalmo driftwoodensis , the oldest known Salmoninae fish in the fossil record , helps scientists figure how the different species of salmon diverged from

2646-581: 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 . Salmon are typically anadromous : they hatch in the shallow gravel beds of freshwater headstreams and spend their juvenile years in rivers , lakes and freshwater wetlands , migrate to

2744-518: The Pacific Northwest and Alaska , salmon are keystone species . 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

2842-456: 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

2940-504: The Quaternary glaciation began the cycle of glacial advance and retreat. There are several other species of fish which are colloquially called "salmon" but are not true salmon. Of those listed below, the Danube salmon or huchen is a large freshwater salmonid closely related (from the same subfamily) to the seven species of salmon above, but others are fishes of unrelated orders , given

3038-654: The Salmo and Oncorhynchus genera also contain a number of trout species informally referred to as salmon. Within Salmo , the Adriatic salmon ( Salmo obtusirostris ) and Black Sea salmon ( Salmo labrax ) have both been named as salmon in English , although they fall outside the generally recognized seven salmon species. The masu salmon ( Oncorhynchus masou ) is actually considered a trout ("cherry trout") in Japan , with masu actually being

Hooliganism (Russian: хулиганство , khuliganstvo ) was listed as a criminal offense, similar to disorderly conduct in some other jurisdictions, and used as a catch-all charge for prosecuting unapproved behavior. Olympic medalist Vasiliy Khmelevskiy was convicted of hooliganism for setting

3234-497: 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

3332-524: 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

3430-473: The ocean as adults and live like sea fish , then return to their freshwater birthplace to reproduce . 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;

3528-590: 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

3626-401: The 1990s the UK government has led a widescale crackdown on football related violence. While football hooliganism has been a growing concern in some continental European countries in recent years, British football fans now tend to have a better reputation abroad. Although reports of British football hooliganism still surface, the instances now tend to occur at pre-arranged locations rather than at

The fauna found in abundance in the lake area, as one approaches along the Luktak Channel and the outlet stream from the lake, are Bald eagles , harbor seals , bears feeding on salmon and mountain goats on the hill slopes. The Chilkoot Lake State Recreation Site is set amidst Sitka trees at the head of the Chilkoot River on the southern shores of

3920-486: The Chilkoot Lake is considered essential to propagate sockeye, coho, hooligan, bears, moose and many other species of wild life. L’uknax Adi clan of Tlingit Indians, whose principal symbol is red salmon or sockeye, traditionally owned Chilkoot Lake and Chilkoot river, also called by the English names after their crest animal as Sockeye Clan, Coho Clan and Salmon Clan. Tlingit clans "historically owned areas of economic production that were most often also places of importance in

4018-529: The Chilkoot Lake. It was established by the State Parks and Outdoor Recreation Division of the Alaska Department of Natural Resources. It is about 10 miles (20 km) northeast of Haines on the Lutak and Chilkoot River roads, or 5 miles (8 km) past the ferry terminal. The site is spread over an area of 80 acres (32 ha) and has camping grounds, picnic shelters and also a boat launching facility. The precincts of

Home-made rafts are plied during the race due its light weight and ease of transportation across the fish weir on the river to continue with the race. The aqua fauna found in the Chilkoot Lake moves down the Chilkoot River. These are mostly Sockeye Salmon or red salmon found in profusion. The lake proliferates in red fish in large numbers and are easily caught. In 1896,

4312-531: The Lower Chilkoot River in 1976 to enumerate the movement of Sockeye fishes from the Chilkoot lake downstream. The road from the Lutak Inlet to the outlet of the lake was extended and improved over a period from 1953 to 1956 by the Alaska Road Commission; the intended purpose was to have access to the recreation area, for quality fishing and access to small boats to the river shores for extracting timber from

4410-468: The North American West Coast salmon sport fishing has completely replaced inshore commercial salmon fishing. In most cases, the commercial value of a salmon sold as seafood can be several times less than the value attributed to the same fish caught by a sport fisherman. This is "a powerful economic argument for allocating stock resources preferentially to sport fishing". Salmon aquaculture

4508-531: The Oakley-street tragedy intimidation had reached an unexampled case. Witnesses had been warned that it would be as much as their life was worth to give evidence against John Darcy. On Wednesday plain-clothes men escorted the witnesses from the court singly. He himself had been warned — not by anonymous letter but through a mysterious personal medium — that if seen in a certain neighbourhood he would be done for. A magistrate had also told him that he had been

4606-558: The Pacific Ocean, the second host releases a stage infective to salmon. The parasite is then carried in the salmon until the next spawning cycle. The myxosporean parasite that causes whirling disease in trout has a similar life cycle. However, as opposed to whirling disease, the Henneguya infestation does not appear to cause disease in the host salmon—even heavily infected fish tend to return to spawn successfully. According to Dr. Kieser,

4704-584: The Spiritual geography of the region". The history of the lake is directly linked to the Chilkoot village, where the Tlingits lived, after which the lake has been named. This village existed near the outlet of the Chilkoot Lake and was divided into two parts by the river; the western part was inhabited by Raven clan Tlingits while the Eagle Clan Tlingits lived on the eastern part. It was an important location for

4802-413: The activity of the gang he referred to was not confined to Lambeth, but extended to numerous other districts. It was composed of young fellows who scorned to do a stroke of work, and obtained a living by blackmailing. It was a common practice for three or four of these men to walk into a shop and offer the shopman the alternative of giving them a dollar for drink or having his shop wrecked. In connection with

4900-432: The adjacent stream is piped into the top of the channel, sometimes via a header pond, to settle out sediment. Spawning success is often much better in channels than in adjacent streams due to the control of floods, which in some years can wash out the natural redds. Because of the lack of floods, spawning channels must sometimes be cleaned out to remove accumulated sediment. The same floods that destroy natural redds also clean

4998-483: The area for commercial purposes. The road on the upstream side of the lake called as 'Cox Road' (named after a homestead owner in upper reach of the river) on the west side of the lake was built in later years in 1968. Use of boats on the Chilkoot Lake and the river from the Tilgit village was in the form of canoes rowed to the "Glory Hole", at the upper end of the lake for harvesting salmons and also for hunting wild life in

5096-633: The comic strip artist and political cartoonist Frederick Burr Opper introduced a character called Happy Hooligan in 1900; "hapless Happy appeared regularly in U.S. newspapers for more than 30 years", a "naive, skinny, baboon-faced tramp who invariably wore a tomato can for a hat." Life brought this up by way of criticizing the Soviet U.N. delegate Yakov A. Malik for misusing the word. Malik had indignantly referred to anti-Soviet demonstrators in New York as "hooligans". Happy Hooligan, Life reminded its readers, "became

5194-608: 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

5292-430: The developing embryos. Mortality of salmon in the early life stages is usually high due to natural predation and human-induced changes in habitat, such as siltation, high water temperatures, low oxygen concentration, loss of stream cover, and reductions in river flow. Estuaries and their associated wetlands provide vital nursery areas for the salmon prior to their departure to the open ocean. Wetlands not only help buffer

5390-520: The development of strong in-groups bonds and intense feelings of antagonism towards outsiders which in turn can facilitate group identification and affect the likelihood of fan violence. Beginning in at least the 1960s, the United Kingdom gained a reputation worldwide for football hooliganism ; the phenomenon was often dubbed the British or English Disease . However, since the 1980s and well into

5488-502: The east. It has been declared as navigable. The lake is in the upper part of the Chilkoot Watershed that spans 100 square miles (260 km) of land 20 miles (32 km) in length and 5 miles (8.0 km) in width. The waters of the lake display turquoise color. The lake is surrounded by mountains and is glacial fed. The lake is deep water body with maximum depth of 300 feet (91 m). The 1,600 acres (6.5 km) of land around

5586-472: The elimination of beavers from large parts of the river system, salmon runs plummeted, even in the absence of many of the factors usually associated with the demise of salmon runs. Salmon recruitment can be affected by beavers' dams because dams can: Beaver dams are able to nurture salmon juveniles in estuarine tidal marshes where the salinity is less than 10 ppm. Beavers build small dams of generally less than 60 cm (2 ft) high in channels in

5684-821: The estuary from silt and pollutants, but also provide important feeding and hiding areas. Salmon not killed by other means show greatly accelerated deterioration ( phenoptosis , or "programmed aging") at the end of their lives. Their bodies rapidly deteriorate right after they spawn as a result of the release of massive amounts of corticosteroids . 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

5782-452: The fish run was so large that the cannery, which processed this fish variety had to put a ceiling on the number of fishes that they would accept from Indian fishermen at 100 per day. It has been reported that the Indians fish in the lake indiscriminately even in the spawning areas of the streams flowing into the lake and place traps (gill-net) under expert guidance for the purpose without observing

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

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

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

Football (soccer) and other sports hooliganism overall is rare in the United States in part because of stricter legal penalties for vandalism and physical violence, club markets having their own territory of fans, venues banning weapons, stricter security during games, and a stronger taboo on politics, class, race, and religion into the American sporting culture. Although isolated drunken fights at games do occur, they rarely escalate to major brawling comparable to Europe and Latin America . In

7252-504: The murder of Henry Mappin in Lambeth committed by a member of the gang drew further attention to the word which was immediately popularised by the press. The London newspaper The Daily Graphic wrote in an article on 22 August 1898, "The avalanche of brutality which, under the name of 'Hooliganism' ... has cast such a dire slur on the social records of South London ." The inquest was carried out by Mr Braxton Hicks who "remarked that

7350-446: 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

7448-525: 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

7546-517: 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

7644-408: 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

7742-619: The recipient of a like indignity." Arthur Conan Doyle wrote in his 1904 short story " The Adventure of the Six Napoleons ", "It seemed to be one of those senseless acts of Hooliganism which occur from time to time, and it was reported to the constable on the beat as such." H. G. Wells wrote in his 1909 semi-autobiographical novel Tono-Bungay , "Three energetic young men of the hooligan type, in neck-wraps and caps, were packing wooden cases with papered-up bottles, amidst much straw and confusion." According to Life magazine (30 July 1951),

7840-466: 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

7938-407: 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

8036-503: 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

8134-568: The same charge has been leveled against members of the feminist punk group Pussy Riot for which three members each received a two-year sentence on 17 August 2012. Hooliganism charges were also levelled against the Greenpeace protesters in October 2013. In March 2022, Marina Ovsyannikova , a Russian journalist who held up a banner protesting the Russian invasion of Ukraine during a national news broadcast,

8232-421: 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

8330-546: 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

8428-468: The southeast Alaskan Tlingits who reportedly settled here during pre-historic days when they subsisted on salmon and hooligan fishing; they used Hooligan fish to make fish oil, their cooking medium, by cooking the fishes in a canoe lined with hot rocks. Chilkoot is a Tlingit phrase which means without a storehouse . The Chilkoot band at one time stored fish packed in snow between alder or willow branches, instead of in storehouses. The population of

8526-408: The specified weekly norm for closing. While scouting the lake area for locating hatcheries, it was observed that spawning beds were located at the head of the lake. Some were sighted on the shores and two streams, where gravity flow could be created and could be used for locating hatcheries. At the head of the lake, there were springs which formed a pool of about 125 feet (40 m) diameter, considered

8624-458: 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

8722-534: 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

8820-488: 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

8918-467: 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

9016-468: The town of Heines. However, building of any new or additional structures and/or road above the Chilkoot Lake has been banned to prevent any harmful effects that may be caused due to the road access, garbage and sewage disposal as that would jeopardize the sensitive salmon spawning grounds in the lake watershed. The Chilkoot Watershed Coalition monitors this closely to prevent any such development. A healthy upper watershed 5 by 1.5 miles (8 by 2 km) covers

9114-597: 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

9212-450: The village dwindled over the years from a figure of 127 people (1880 census), just to 2 houses with 7 people in June 1990 and was finally abandoned. Another factor for desertion of the village is attributed to the cannery industries that got established in the area for processing salmons that were fished from the lake and the river, in Haines and other places in the late 19th and early 20th century;

9310-417: 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

9408-606: The word may have originated from the surname of a rowdy Irish family in a music hall song of the 1890s. Clarence Rook , in his 1899 book Hooligan Nights , wrote that the word came from Patrick Hoolihan (or Hooligan), an Irish bouncer and thief who lived in London . In 2015, the BBC Scotland TV programme The Secret Life of Midges noted that the English commander-in-chief during the Jacobite rising of 1745 , General Wade , misheard

9506-435: 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

9604-621: 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
