Saithe
''Pollachius virens'' is a species of marine fish in the genus '' Pollachius''. Together with '' P. pollachius'', it is generally referred to in the United States as pollock. It is commonly known in Britain as the coalfish, coley, or saithe ( or ), and the young fish may also be called podleys or cuddies in Scotland and northern England. Description This species can be separated from ''P. pollachius'' by looking at the relative lengths of the upper and lower jaws. ''P. pollachius'' has a longer underslung lower jaw while ''P. virens'' has approximately equal upper and lower jaw lengths. This gives a very different profile to the head. In general, ''P. pollachius'' is a brown or golden colour with a dark back while ''P. virens'' is bright silver with a very dark green back. ''P. virens'' generally appears to have relatively smaller eyes. The lateral line of ''P. pollachius'' has a noticeable kink over the pectoral fins while that of ''P. virens'' is straighter. The flesh of coalf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northern Atlantic
The Atlantic Ocean is the second largest of the world's five oceanic divisions, with an area of about . It covers approximately 17% of Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an age of exploration and colonization of the Americas by European powers, most notably Portugal, Spain, France, and the United Kingdom. From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saltstraumen
or is a small strait with one of the strongest Tide, tidal currents in the world. It is located in Bodø Municipality in Nordland county, Norway. It is located about southeast of the Bodø (town), town of Bodø. The narrow channel connects the outer Saltfjorden to the large Skjerstad Fjord between the islands of Straumøya and Knaplundsøya. The Saltstraumen Bridge on Norwegian County Road 17 crosses Saltstraumen. Current Saltstraumen has one of the strongest tidal currents in the world. Up to of seawater forces its way through a long and wide strait every six hours. Vortex, Vortices known as whirlpools or Maelstrom (whirlpool), maelstroms up to in diameter and in depth are formed when the current is at its strongest. At this point, one source claims that the tidal current can reach . Saltstraumen has existed for about two to three thousand years. Before that, the area was different due to post-glacial rebound. The current is created when the tide tries to fill Skjers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollachius
Pollock or pollack (pronounced ) is the common name used for either of the two species of North Atlantic ocean, marine fish in the genus ''Pollachius''. ''Pollachius pollachius'' is referred to as "pollock" in North America, Ireland and the United Kingdom, while ''Pollachius virens'' is usually known as saithe or coley in Great Britain and Ireland (derived from the older name coalfish). Other names for ''P. pollachius'' include the Atlantic pollock, European pollock, ''lieu jaune'', and lythe or lithe; while ''P. virens'' is also known as Boston blue (distinct from bluefish) and silver bill. Species The recognized species in this genus are: * ''Pollachius pollachius'' (Carl Linnaeus, Linnaeus, 1758) (pollack) * ''Pollachius virens'' (Linnaeus, 1758) (coalfish) Description Both species can grow to . ''P. virens'' can weigh up to and ''P. pollachius'' can weigh up to . ''P. virens'' has a strongly defined, silvery lateral line running down the sides. ...

Pollachius Pollachius
''Pollachius pollachius'' is a species of marine fish in the family Gadidae. FAO uses the English name pollack for this species, whereas in American English it is known as European pollock. Other vernacular names include ''lythe'', and in the Isle of Man, '' callig''. It is common in the north-eastern parts of the Northern Atlantic, including the Bay of Biscay and North Sea. Adults can grow up to and weigh up to , although more commonly their maximum length is . Ecology and life history Pollack are fast-growing and relatively short-lived. The maximum reported age is 15 years. They are said to spawn offshore, although their spawning grounds are poorly known; a study of a fjord population in Norway suggested local spawning. Pollack are benthopelagic, that is, they live near the sea floor. They seem to be relatively sedentary. Fisheries Pollack is of value to fisheries, although it mainly represents bycatch.

North Sea
The North Sea lies between Great Britain, Denmark, Norway, Germany, the Netherlands, Belgium, and France. A sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind energy, wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Viking Age, Vikings' rise. The Hanseatic League, the Dutch Golden Age, Dutch Republic, and Kingdom of Great Britain, Brita ...

Groundfish
Demersal fish, also known as groundfish, live and feed on or near the bottom of seas or lakes (the demersal zone).Walrond Carl . "Coastal fish - Fish of the open sea floor"Te Ara - the Encyclopedia of New Zealand. Updated 2 March 2009 They occupy the sea floors and lake beds, which usually consist of mud, sand, gravel or rocks. In coastal waters, they are found on or near the continental shelf, and in deep waters, they are found on or near the continental slope or along the continental rise. They are not generally found in the deepest waters, such as abyssal depths or on the abyssal plain, but they can be found around seamounts and islands. The word ''demersal'' comes from the Latin ''demergere'', which means ''to sink''. Demersal fish are bottom feeders. They can be contrasted with pelagic fish, which live and feed away from the bottom in the open water column. Demersal fish fillets contain little fish oil (one to four per cent), whereas pelagic fish can contain up to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barents Sea
The Barents Sea ( , also ; , ; ) is a marginal sea of the Arctic Ocean, located off the northern coasts of Norway and Russia and divided between Norwegian and Russian territorial waters.World Wildlife Fund, 2008. It was known earlier among Russians as the Northern Sea, Pomorsky Sea or Murman Sea ("Norse Sea"); the current name of the sea is after the historical Netherlands, Dutch navigator Willem Barentsz.

It is bordered by the Kola Peninsula to the south, the shelf edge towards the Norwegian Sea to the west, the archipelagos of Svalbard to the northwest, Franz Josef Land to the northeast and Novaya Zemlya to the east. The islands of Novaya Zemlya, an extension of the northern end of the Ural Mountains, separate the Barents Sea from the Kara Sea. Although part of the Arctic Ocean, the Barents Sea ...

Longline Fishing
Longline fishing, or longlining, is a commercial fishing angling technique that uses a long ''main line'' with baited hooks attached at intervals via short branch lines called ''snoods'' or ''gangions''.Method and Apparatus for Long Line and Recreational Bait Fishing Patent application 20080202013. 28 August 2008. A snood is attached to the main line using a clip or swivel, with the hook at the other end. Longlines are classified mainly by where they are placed in the water column. This can be at the surface or at the bottom. Lines can also be set by means of an anchor, or left to drift. Hundreds or even thousands of baited hooks can hang from a single line. This can lead to the death of many differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
