Atlantic Cod North East Atlantic Cod North West Atlantic Cod

In the western Atlantic Ocean cod has a distribution north of Cape Hatteras, North Carolina, and round both coasts of Greenland; in the eastern Atlantic it is found from the Bay of BiscayNot to be confused with the North American Biscayne Bay. The Bay of Biscay (French: Golfe de Gascogne Spanish: Mar Cantabrico is an arm of the North Atlantic Ocean. It lies along the western coast of France from Brest south to the Spanish border, and the north to the Arctic OceanThe Arctic Ocean located entirely in the north polar region, is the smallest of the world's five oceans (after the Pacific Ocean, Atlantic Ocean, Indian Ocean, and Southern Ocean), and the shallowest. It occupies a roughly circular basin and covers an are, including the North SeaThe North Sea is a sea of the Atlantic Ocean, located between the coasts of Norway and Denmark in the east, the coast of the British Isles in the west, and the German, Dutch, Belgian and French coasts in the south.

Icelandic de facto''. and the Barents SeaThe Barents Sea is part of the Arctic Ocean located north of Norway and Russia. It is a rather deep shelf sea (average depth 230 m), bordered by the shelf edge towards the Norwegian Sea in the west, the island of Svalbard (Norway) in the north-west, and t, which is the most important feeding area.

Cod populations or stocks can differ significantly both in appearance and biology. For instance, the cod stocks of the Baltic Sea are adapted to low-salinity water. Organizations such as the Northwest Atlantic Fishery Organization (NAFO) and ICESThe International Council for the Exploration of the Sea (ICES was established in 1902 by eight northern European nations. ICES today has nineteen member nations from both Europe and North America. In the early years the aim of ICES as a scientific organi divide the cod into management units or stocks; however these units are not always biologically distuigishable stocks. Some major stocks/management units on the the Canadian/US shelf are (see map of NAFO areas) are the Southern Labrador-Eastern Newfoundland stock (NAFO divisions 2J3KL), the Northern Gulf of St. Lawrence stock (NAFO divisions 3Pn4RS), the Northern Scotian Shelf stock (NAFO divisions 4VsW), which all lie in Canadian waters, and the Georges Bank and Gulf of Maine stocks in USA waters. In the European Atlantic, there are separate stocks on the shelves of Iceland, the Faeroes, and Western Scotland, in the North Sea, Irish Sea and Celtic Sea, and two stocks in the Baltic Sea (the western and the eastern stock).

1 North-East Atlantic Cod

The North-East Arctic stock (also known as the Arcto-Norwegian stock), is at present the world's largest stock of Atlantic cod. It is also recognised as skrei (a Norwegian name meaning something like "the wanderer", distinguishing it from the non-migrating coastal cod). This stock spawn in March-April on the Norwegian coast, traditionally in the region of LofotenThe Lofoten Islands (or simply Lofoten are an archipelago of islands at the 67th and 68th degree parrallels in the Arctic circle, off the Northwest coast of Norway. The principal islands, running from north to south, are Austvagoy (526. 7 km²), Gimsoya (4, but also both further north and south. Newly hatched larvae drift northwards with the coastal current while feeding on larval copepodCalanoida Cyclopoida Gelyelloida Harpacticoida Misophrioida Monstrilloida Mormonilloida Platycopioida Poecilostomatoida Siphonostomatoida Copepods are small, aquatic animals living in the sea and nearly every freshwater habitat, a form of plankton, specifs. In the summer, they have reached the Barents Sea, where they stay for the rest of their life except for their spawning migrations towards Lofoten. As they grow, they turn to krill and other crustaceans, and then to small fish. Adult cod feed mainly on fish such as capelin and herring. The North-East Arctic Cod also shows cannibalistic behaviour, especially when there is little capelin available. The spawning stock was more than 1,000,000 tons just after World War II but then declined to a historic mimimum of just 118,000 tons in 1987. The catch reached an historic maximum in 1956 (1,343,000 tons) and a minimum in 1990 (212,000 tons). Since 2000, the spawning stock has increased quite fast (both due to a low fishing pressure). However, there are worries about a decreased age at first spawning (often an early sign of stock collapse) and the level of discards and unreported catches. The total catch in 2003 it was 521,949 tons, Norway (191,976 tons) and Russia (182,160 tons) being the major exploiters (Source: ICES).

The North Sea cod stock is subject to an important cod fishery, mainly performed by European Union states (in 1999: Denmark: 31%; Scotland: 25%; the UK (England, Wales and Northern Ireland): 12%; the Netherlands: 10%; Belgium, Germany and Norway: 17%). In the 1970s, the annual catch was 200-300 000 tonnes, but catch quotas has repeatedly been reduced in the 1980s and 1990s. In spite of this, the spawning stock biomass is estimated to have been well below the precautionary level since 1984 and is at present at an historically low level. In 2003, ICES stated the there is a high risk of stock collapse if current exploitation levels continues, and recommended a recovery plan which included a total moratorium on cod fishing in the North Sea in 2004. At the December 2003 meeting in Brussels, the EU Council of Ministers decided that the international Total Allowable Catch for North Sea cod should be 27,300 tonnes in 2004.

2 North-West Atlantic Cod

The North-West Atlantic Cod has been regarded as heavily overfished throughout its range, resulting in a crash in the fishery in the United States and Canada during the early nineties. The fishery has yet to recover, and may not recover at all because of a possibly stable change in the food web. The North-west Atlantic populations spawn in the winter and spring in the Cape Cod region in a location called Georges Bank .

The IUCN lists the species as vulnerable.
