Cod
Cod is the common name for the genus "Gadus" of demersal fishes, belonging to the family Gadidae. Cod is also used as part of the common name for a number of other fish species, and some species suggested to belong to genus "Gadus" are not called cod (the Alaska pollock). The two most common species of cod are the Atlantic cod ("Gadus morhua"), which lives in the colder waters and deeper sea regions throughout the North Atlantic, and the Pacific cod ("Gadus macrocephalus"), found in both eastern and western regions of the northern Pacific. "Gadus morhua" was named by Linnaeus in 1758. (However, "G. morhua callarias", a low-salinity, nonmigratory race restricted to parts of the Baltic, was originally described as "Gadus callarias" by Linnaeus.)
Cod fisheries
Cod fisheries are fisheries for cod. Cod is the common name for fish of the genus "Gadus", belonging to the family Gadidae, and this article is confined to the three species that belong to this genus: the Atlantic cod, the Pacific cod and the Greenland cod. Cod are demersal fish found in huge schools confined to temperate waters in the northern hemisphere. Atlantic cod are found in the colder waters and deeper sea regions throughout the Northern Atlantic. The Pacific cod is found in both eastern and western regions of the Pacific. Atlantic cod can grow to in length. Its average weight is , but specimens weighing up to have been recorded.
Murray cod
The Murray cod ("Maccullochella peelii") is a large Australian predatory freshwater fish of the "Maccullochella" genus and the Percichthyidae family. Although the species is called a cod in the vernacular, it is not related to the Northern Hemisphere marine cod ("Gadus") species. The Murray cod is an important part of Australia's vertebrate wildlife—as an apex predator in the Murray-Darling River system—and also significant in Australia's human culture. The Murray cod is the largest exclusively freshwater fish in Australia, and one of the largest in the world. Other common names for Murray cod include cod, greenfish, goodoo, Mary River cod, Murray perch, ponde, pondi and Queensland freshwater cod.
Atlantic cod
The Atlantic cod ("Gadus morhua") is a benthopelagic fish of the family Gadidae, widely consumed by humans. It is also commercially known as cod or codling. Dry cod may be prepared as unsalted stockfish, as cured salt cod or clipfish. In the western Atlantic Ocean, cod has a distribution north of Cape Hatteras, North Carolina, and around both coasts of Greenland and the Labrador Sea; in the eastern Atlantic, it is found from the Bay of Biscay north to the Arctic Ocean, including the Baltic Sea, the North Sea, Sea of the Hebrides, areas around Iceland and the Barents Sea. The largest individual on record was 6 feet (1.8 m) long and weighed 211 lb (96 kg), however usually the cod is between 24 inches (61 cm) and 4 feet (1.2 m) long, and weighs 88 lb (40 kg).
Demersal fish
Demersal fish live and feed on or near the bottom of seas or lakes (the demersal zone). 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.
Canadian Atlantic Cod
Canadian Atlantic Cod or "Gadus morhua", are cold water fish, which weigh 2 to 3 kg in the wild . Atlantic Cod were originally found in the Atlantic Ocean, along the borders of both Canada and England and all the way down to the southern United States. Heavy fishing in these areas, in the late 1800s and early 1900s led to a massive decline in Cod population. Today, they are grown in onshore temperature controlled, seawater tanks as eggs and eventually taken to sea cages when more developed. The majority of these artificial environments found in Canada, are located in British Columbia, New Brunswick and as well as Newfoundland and Labrador.
Greenland cod
The Greenland cod ("Gadus ogac"), commonly known also as ogac, is a species of ray-finned fish in the cod family, Gadidae. Genetic analysis has shown that it may be the same species as the Pacific cod ("Gadus macrocephalus"). It is a bottom-dwelling fish and is found on the continental shelf in the Arctic Ocean and northwestern Atlantic Ocean, its range extending from Alaska to West Greenland, then southwards along the Canadian coast to the Gulf of St. Lawrence and Cape Breton Island. It is a commercially harvested food fish, but landings have been greatly reduced in recent years. Molecular genetic analyses strongly suggest that Greenland cod is not different from Pacific cod, "Gadus macrocephalus" - "Gadus ogac" is then a junior synonym of "G. macrocephalus".
