198-501: 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

297-514: A Norman development while chase is the French equivalent imported with a different meaning. Distinctions in meaning between Anglo-Norman and French have led to many faux amis (words having similar form but different meanings) in Modern English and Modern French. Although it is a Romance language, Norman contains a significant amount of lexical material from Old Norse . Because of this, some of

396-442: 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

495-473: 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

594-749: 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. Anglo-Norman language Anglo-Norman ( Norman : Anglo-Normaund ; French : Anglo-normand ), also known as Anglo-Norman French ,

693-569: 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

792-524: A hush sibilant not recorded in French mousseron , as does cushion for coussin . Conversely, the pronunciation of the word sugar resembles Norman chucre even if the spelling is closer to French sucre . It is possible that the original sound was an apical sibilant, like the Basque s , which is halfway between a hissing sibilant and a hushing sibilant. The doublets catch and chase are both derived from Low Latin *captiare . Catch demonstrates

891-681: A language did exist, and that it was the language descended from the Norman French originally established in England after the Conquest. When William the Conqueror led the Norman conquest of England in 1066, he, his nobles, and many of his followers from Normandy , but also those from northern and western France, spoke a range of langues d'oïl (northern varieties of Old French ). This amalgam developed into

990-571: A language of business communication, especially when it traded with the continent, and several churches used French to communicate with lay people. A small but important number of documents survive associated with the Jews of medieval England, some featuring Anglo-French written in Hebrew script, typically in the form of glosses to the Hebrew scriptures. As a langue d'oïl , Anglo-Norman developed collaterally to

1089-532: 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

1188-481: A second language among the upper classes. Moreover, with the Hundred Years' War and the growing spirit of English and French nationalism, the status of French diminished. French (specifically Old French ) was the mother tongue of every English king from William the Conqueror (1066–1087) until Henry IV (1399–1413). Henry IV was the first to take the oath in ( Middle ) English, and his son, Henry V (1413–1422),

1287-412: 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

1386-562: A velar plosive where French has a fricative : Some loans were palatalised later in English, as in the case of challenge (< Old Norman calonge , Middle English kalange, kalenge , later chalange ; Old French challenge, chalonge ). There were also vowel differences: Compare Anglo-Norman profound with Parisian French profond , soun sound with son , round with rond . The former words were originally pronounced something like 'profoond', 'soon', 'roond' respectively (compare

1485-717: A very high level of development. The important Benedictine monasteries both wrote chronicles and guarded other works in Old English . However, with the arrival of the Normans, Anglo-Saxon literature came to an end and literature written in Britain was in Latin or Anglo-Norman. The Plantagenet kings encouraged this Anglo-Norman literature . Nevertheless, from the beginning of the 14th century, some authors chose to write in English, such as Geoffrey Chaucer . The authors of that period were influenced by

1584-605: A written and literary language probably owes something to this history of bilingualism in writing. Around the same time, as a shift took place in France towards using French as a language of record in the mid-13th century, Anglo-Norman also became a language of record in England, although Latin retained its pre-eminence for matters of permanent record (as in written chronicles ). From around this point onwards, considerable variation begins to be apparent in Anglo-Norman, which ranges from

1683-617: Is Buttevant (from the motto of the Barry family: Boutez en avant , "Push to the Fore"), the village of Brittas (from the Norman bretesche , "boarding, planking") and the element Pallas (Irish pailís , from Norman paleis , "boundary fence": compare palisade , The Pale ). Others exist with English or Irish roots, such as Castletownroche , which combines the English Castletown and

1782-836: 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

1881-680: 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 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

1980-459: Is evidence, too, that foreign words ( Latin , Greek , Italian , Arabic , Spanish ) often entered English via Anglo-Norman. The language of later documents adopted some of the changes ongoing in continental French and lost many of its original dialectal characteristics, so Anglo-French remained (in at least some respects and at least at some social levels) part of the dialect continuum of modern French, often with distinctive spellings. Over time,

2079-441: 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

2178-521: Is still evident in official and legal terms where the ordinary sequence of noun and adjective is reversed , as seen in phrases such as Blood Royal, attorney general, heir apparent, court martial, envoy extraordinary and body politic. The royal coat of arms of the United Kingdom still features in French the mottos of both the British Monarch , Dieu et mon droit ("God and my right"), and

2277-946: 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

2376-481: Is the common name for several commercially important species of euryhaline ray-finned fish from the genera Salmo and Oncorhynchus of the family Salmonidae , native to tributaries of the North Atlantic ( Salmo ) and North Pacific ( Oncorhynchus ) basins. Other closely related fish in the same family include trout , char , grayling , whitefish , lenok and taimen , all coldwater fish of

2475-476: 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

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,

2673-484: 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

2772-575: The Order of the Garter , Honi soit qui mal y pense ("Shamed be he who thinks evil of it"). Dieu et mon droit was first used by Richard I (who spoke Anglo-Norman, but cannot be proved to have been able to speak English) in 1198 and adopted as the royal motto of England in the time of Henry VI . The motto appears below the shield of the Royal Coat of Arms. Though in regular use at the royal court, Anglo-French

2871-518: 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

2970-456: 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

3069-504: 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

3168-654: 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

3267-497: 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

3366-524: 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

3465-590: 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

3564-610: 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 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

3663-826: The subfamily Salmoninae . The genus Salmo contains 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

3762-514: The 19th century, but these words are probably linguistic traces of Saxon or Anglo-Scandinavian settlements between the 4th and the 10th centuries in Normandy. Otherwise the direct influence of English in mainland Norman (such as smogler "to smuggle") is from direct contact with English in later centuries, rather than Anglo-Norman. When the Normans conquered England, Anglo-Saxon literature had reached

3861-659: The Anglo-Norman of medieval England. Many of the earliest documents in Old French are found in England. In medieval France , it was not usual to write in the vernacular : Because Latin was the language of the Church , education , and historiography , it was also used for records. In medieval England, Latin also remained in use by the Church, the royal government, and much local administration in parallel with Middle English , as it had been before 1066. The early adoption of Anglo-Norman as

3960-419: The French language used in England changed from the end of the 15th century into Law French , that was used since the 13th century. This variety of French was a technical language, with a specific vocabulary, where English words were used to describe everyday experience, and French grammatical rules and morphology gradually declined, with confusion of genders and the adding of -s to form all plurals. Law French

4059-619: The House of Commons to endorse them during their progress to becoming law, or spoken aloud by the Clerk of the Parliaments during a gathering of the Lords Commissioners , to indicate the granting of Royal Assent to legislation. The exact spelling of these phrases has varied over the years; for example, s'avisera has been spelled as s'uvisera and s'advisera , and Reyne as Raine . Though

4158-453: The Norman or French word supplanted the original English term, or both words would co-exist but with slightly different nuances. In other cases, the Norman or French word was adopted to signify a new reality, such as judge , castle , warranty . In general, the Norman and French borrowings concerned the fields of culture, aristocratic life, politics and religion, and war whereas the English words were used to describe everyday experience. When

4257-596: The Normans (Norsemen) and was then brought over after the Conquest and established firstly in southern English dialects. It is, therefore, argued that the word mug in English shows some of the complicated Germanic heritage of Anglo-Norman. Many expressions used in English today have their origin in Anglo-Norman (such as the expression before-hand , which derives from Anglo-Norman avaunt-main ), as do many modern words with interesting etymologies. Mortgage , for example, literally meant death-wage in Anglo-Norman. Curfew (fr. couvre-feu ) meant cover-fire , referring to

4356-407: The Normans arrived in England, their copyists wrote English as they heard it, without realising the peculiarities of the relationship between Anglo-Saxon pronunciation and spelling and so the spelling changed. There appeared different regional Modern-English written dialects, the one that the king chose in the 15th century becoming the standard variety. In some remote areas, agricultural terms used by

4455-468: 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

4554-558: 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,

4653-432: 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

4752-549: The central Old French dialects which would eventually become Parisian French in terms of grammar , pronunciation and vocabulary . Before the signature of the Ordinance of Villers-Cotterêts in 1539, French was not standardised as an administrative language throughout the kingdom of France. Middle English was heavily influenced by Anglo-Norman and, later, Anglo-French. W. Rothwell has called Anglo-French 'the missing link ' because many etymological dictionaries seem to ignore

4851-479: The central langue d'oïl dialects that developed into French. English therefore, for example, has fashion from Norman féchoun as opposed to Modern French façon (both developing from Latin factio, factiōnem ). In contrast, the palatalization of velar consonants before /a/ that affected the development of French did not occur in Norman dialects north of the Joret line . English has therefore inherited words that retain

4950-608: 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

5049-556: The continent, English sometimes preserves earlier pronunciations. For example, ch used to be /tʃ/ in Medieval French, where Modern French has /ʃ/ , but English has preserved the older sound (in words like chamber, chain, chase and exchequer ). Similarly, j had an older /dʒ/ sound, which it still has in English and some dialects of modern Norman, but it has developed into /ʒ/ in Modern French. The word mushroom preserves

5148-542: The contribution of that language in English and because Anglo-Norman and Anglo-French can explain the transmission of words from French into English and fill the void left by the absence of documentary records of English (in the main) between 1066 and c.  1380 . Anglo-Norman continued to evolve significantly during the Middle Ages by reflecting some of the changes undergone by the northern dialects of mainland French. For example, early Anglo-Norman legal documents used

5247-430: 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

5346-472: 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

5445-821: 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

5544-432: 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; 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

5643-443: The fish. There they deposit nutrient-rich urine and feces and partially eaten carcasses. 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

5742-566: 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

5841-417: The great mass of ordinary people spoke forms of English, French spread as a second language due to its prestige, encouraged by its long-standing use in the school system as a medium of instruction through which Latin was taught. In the courts, the members of the jury , who represented the population, had to know French in order to understand the plea of the lawyer. French was used by the merchant middle class as

5940-426: The judge, the lawyer, the complainant or the witnesses. The judge gave his sentence orally in Norman, which was then written in Latin. Only in the lowest level of the manorial courts were trials entirely in English.

Nevertheless,

6039-461: The king in 1275. With effect from the 13th century, Anglo-Norman therefore became used in official documents, such as those that were marked by the private seal of the king whereas the documents sealed by the Lord Chancellor were written in Latin until the end of the Middle Ages. English became the language of Parliament and of legislation in the 15th century, half a century after it had become

6138-468: The language of the king and most of the English nobility. During the 11th century, development of the administrative and judicial institutions took place. Because the king and the lawyers at the time normally used French, it also became the language of these institutions. From the 11th century until the 14th century, the courts used three languages: Latin for writing, French as the main oral language during trials, and English in less formal exchanges between

6237-568: The late 14th century onwards. Although Anglo-Norman and Anglo-French were eventually eclipsed by modern English , they had been used widely enough to influence English vocabulary permanently. This means that many original Germanic words, cognates of which can still be found in Nordic , German , and Dutch , have been lost or, as is more often the case, exist alongside synonyms of Anglo-Norman French origin. Anglo-Norman had little lasting influence on English grammar, as opposed to vocabulary, although it

6336-681: 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

6435-458: 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

6534-446: 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

6633-442: The phrase "del roy" (of the king), whereas by about 1330 it had become "du roi" as in modern French. Anglo-Norman morphology and phonology can be deduced from its heritage in English. Mostly, it is done in comparison with continental Central French. English has many doublets as a result of this contrast: Compare also: The palatalization of velar consonants before the front vowel produced different results in Norman to

6732-517: 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

6831-408: 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

6930-466: 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

7029-407: 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

7128-943: The rural workers may have been derived from Norman French. An example is the Cumbrian term sturdy for diseased sheep that walk in circles, derived from étourdi meaning dizzy. The Norman invasion of Ireland began in 1169, on the first of May in Bannow Bay , and led to Anglo-Norman control of much of the island. Norman-speaking administrators arrived to rule over the Angevin Empire 's new territory. Several Norman words became Gaelic words, including household terms: garsún (from Norman garçun , "boy"); cóta ( cote , "cloak"); hata ( hatte , "hat"); gairdín ( gardin , "garden"); and terms relating to justice (Irish giúistís , bardas (corporation), cúirt (court)). Place-names in Norman are few, but there

7227-503: 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

7326-457: The settlers who came with William the Conqueror, but also the continued influence of continental French during the Plantagenet period . Though it is difficult to know much about what was actually spoken, as what is known about the dialect is restricted to what was written, it is clear that Anglo-Norman was, to a large extent, the spoken language of the higher social strata in medieval England. It

7425-421: 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

7524-423: The similarly denasalised vowels of modern Norman), but later developed their modern pronunciation in English. The word veil retains the /ei/ (as does modern Norman in vaile and laîsi ) that in French has been replaced by /wa/ voile , loisir . Since many words established in Anglo-Norman from French via the intermediary of Norman were not subject to the processes of sound change that continued in parts of

7623-546: 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

7722-458: 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

7821-534: 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

7920-453: The time in the evening when all fires had to be covered to prevent the spread of fire within communities with timber buildings. The word glamour is derived from Anglo-Norman grammeire , the same word which gives us modern grammar ; glamour meant first "book learning" and then the most glamorous form of book learning, "magic" or "magic spell" in Medieval times. The influence of Anglo-Norman

8019-488: 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

8118-467: 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

8217-414: The unique insular dialect now known as Anglo-Norman French, which was commonly used for literary and eventually administrative purposes from the 11th until the 14th century. The term "Anglo-Norman" harks back to the time when the language was regarded as being primarily the regional dialect of the Norman settlers. Today the generic term "Anglo-French" is used instead to reflect not only the broader origin of

8316-437: The use of Anglo-French expanded into the fields of law, administration, commerce, and science, in all of which a rich documentary legacy survives, indicative of the vitality and importance of the language. By the late 15th century, however, what remained of insular French had become heavily anglicised: see Law French . It continued to be known as "Norman French" until the end of the 19th century even though, philologically, there

8415-597: 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

8514-477: The very local (and most anglicised ) to a level of language which approximates to and is sometimes indistinguishable from varieties of continental French. Typically, therefore, local records are rather different from continental French, with diplomatic and international trade documents closest to the emerging continental norm. English remained the vernacular of the common people throughout this period. The resulting virtual trilingualism in spoken and written language

8613-417: 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

8712-665: The words introduced to England as part of Anglo-Norman were of Germanic origin. Indeed, sometimes one can identify cognates such as flock (Germanic in English existing prior to the Conquest) and floquet (Germanic in Norman). The case of the word mug demonstrates that in instances, Anglo-Norman may have reinforced certain Scandinavian elements already present in English. Mug had been introduced into northern English dialects by Viking settlement. The same word had been established in Normandy by

8811-471: The works of contemporary French writers whose language was prestigious. Chaucer - himself of Norman origin - is considered to be the father of the English language and the creator of English as a literary language. The major Norman-French influence on English can still be seen in today's vocabulary. An enormous number of Norman-French and other medieval French loanwords came into the language, and about three-quarters of them are still used today. Very often,

8910-568: 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 the Great Lakes of North America , Patagonia in South America and South Island of New Zealand . The Modern English term salmon

9009-615: Was a dialect of Old Norman that was used in England and, to a lesser extent, other places in Great Britain and Ireland during the Anglo-Norman period. According to some linguists, the name Insular French might be more suitable, because "Anglo-Norman" is constantly associated with the notion of a mixed language based on English and Norman. According to some, such a mixed language never existed. Other sources, however, indicate that such

9108-628: Was banished from the courts of the common law in 1731, almost three centuries after the king ceased speaking primarily French. French was used on moots in the Inner Temple until 1779. Anglo-Norman has survived in the political system in the use of certain Anglo-French set phrases in the Parliament of the United Kingdom , where they are written by hand on bills by the Clerk of the Parliaments or Clerk of

9207-457: Was not the main administrative language of England: Latin was the major language of record in legal and other official documents for most of the medieval period. However, from the late 12th century to the early 15th century, Anglo-French was much used in law reports, charters, ordinances, official correspondence, and trade at all levels; it was the language of the King, his court and the upper class. There

9306-473: Was nothing Norman about it. Among important writers of the Anglo-Norman cultural commonwealth is Marie de France . The languages and literature of the Channel Islands are sometimes referred to as Anglo-Norman, but that usage is derived from the French name for the islands: les îles anglo-normandes . The variety of French spoken in the islands is related to the modern Norman language , and distinct from

9405-485: Was one of medieval Latin, Anglo-Norman and Middle English. From the time of the Norman Conquest (1066) until the end of the 14th century, French was the language of the king and his court. During this period, marriages with French princesses reinforced the royal family's ties to French culture. Nevertheless, during the 13th century, intermarriages with English nobility became more frequent. French became progressively

9504-621: 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

9603-513: Was spoken in the law courts, schools, and universities and, in due course, in at least some sections of the gentry and the growing bourgeoisie. Private and commercial correspondence was carried out in Anglo-Norman or Anglo-French from the 13th to the 15th century though its spelling forms were often displaced by continental French spellings. Social classes other than the nobility became keen to learn French: manuscripts containing materials for instructing non-native speakers still exist, dating mostly from

9702-411: Was the first to write in English. By the end of the 15th century, French became the second language of a cultivated elite. Until the end of the 13th century, Latin was the language of all official written documents. Nevertheless, some important documents had their official Norman translation, such as Magna Carta of 1215. The first official document written in Anglo-Norman was a statute promulgated by

9801-483: Was very asymmetrical: very little influence from English was carried over into the continental possessions of the Anglo-Norman kings. Some administrative terms survived in some parts of mainland Normandy: forlenc (from furrow , compare furlong ) in the Cotentin Peninsula and Bessin , and a general use of the word acre (instead of French arpent ) for land measurement in Normandy until metrication in
