Cod is the common name for the demersal fish genus Gadus, belonging to the family Gadidae. Cod is also used as part of the common name for a number of other fish species, and one species that belongs to genus Gadus is commonly not called cod.
Ophidiiformes is an order of ray-finned fish that includes the cusk-eels, pearlfishes, viviparous brotulas, and others. Members of this order have small heads and long slender bodies. They have either smooth scales or no scales, a long dorsal fin and an anal fin that typically runs into the caudal fin. They mostly come from the tropics and subtropics, and live in both freshwater and marine habitats, including abyssal depths. They have adopted a range of feeding methods and lifestyles, including parasitism. The majority are egg-laying, but some are viviparous.
The haddock is a saltwater ray-finned fish from the family Gadidae, the true cods. It is the only species in the monotypic genus Melanogrammus. It is found in the North Atlantic Ocean and associated seas where it is an important species for fisheries, especially in northern Europe where it is marketed fresh, frozen and smoked; smoked varieties include the Finnan haddie and the Arbroath smokie.
Boreogadus saida, known as the polar cod or as the Arctic cod, is a fish of the cod family Gadidae, related to the true cod. Another fish species for which both the common names Arctic cod and polar cod are used is Arctogadus glacialis.
The Greenland cod, 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. 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.
The Pacific cod, Gadus macrocephalus, is a species of ray-finned fish in the family Gadidae. It is a bottom-dwelling fish found in the northern Pacific Ocean, mainly on the continental shelf and upper slopes, to depths of about 900 m (3,000 ft). It can grow to a length of a meter or so and is found in large schools. It is an important commercial food species and is also known as gray cod or grey cod, and grayfish or greyfish. Fishing for this species is regulated with quotas being allotted for hook and line fishing, pots, and bottom trawls.
Gadus is a genus of demersal fish in the family Gadidae, commonly known as cod, although there are additional cod species in other genera. The best known member of the genus is the Atlantic cod.
Guttigadus globosus, the tadpole cod, is a deepwater fish found in the oceanic islands off New Zealand and in the mid South Atlantic at depths ranging from 1200 to 1600 m.
Arctogadus glacialis, known also with ambiguous common names Arctic cod and polar cod, is an Arctic species of fish in the cod family Gadidae, related to the true cod. Arctogadus glacialis is found in icy water. They grow to about 30 cm long, and are favorite food of narwhals and other arctic whales.
Nototheniidae, the notothens or cod icefishes, is a family of ray-finned fishes, part of the suborder Notothenioidei which is traditionally placed within the order Perciformes. They are largely found in the Southern Ocean.
The poor cod, Trisopterus minutus, is a temperate marine fish belonging to the cod family (Gadidae). It is red brown in colour and has a pronounced chin barbel. It may grow up to a length of 40 cm. It is usually found in small shoals at depths between 10 and 300 metres on muddy or sandy bottoms. Its distribution spans the eastern Atlantic, from Norwegian coasts to Portugal and along the Atlantic coast of Morocco; also in the Mediterranean. Spawning takes place towards the end of winter. They are often regarded as a mini species and are commonly confused with pouting as they have a similar appearance. They are often seen as a menace for anglers and have little commercial value and so are not currently at any risk of extinction.
Merlangius merlangus, commonly known as Whiting or merling, is an important food fish in the eastern North Atlantic Ocean and the northern Mediterranean, western Baltic, and Black Sea. In Anglophonic countries outside the Whiting's natural range, the name "whiting" has been applied to various other species of fish.
The skilfish, Erilepis zonifer, is one of two members of the fish family Anoplopomatidae and the only species in the genus Erilepis. It is also known as black cod, though they have no relation to cod, family Gadidae, and sable fish or sablefish, which is a name commonly used for other species in the family Anoplopomatidae. Found on deep rocky bottoms in the North Pacific at depths of up to 440 metres, they can reach up to 1.83 metres in length and weigh up to 91 kilograms. Young fish display striking white blotches on their body, however their colour changes to dark grey with maturity, and the bright markings become duller and less visible as they grow, similar to the Tiger shark's stripes.
Pleuronectidae, also known as righteye flounders, are a family of flounders. They are called "righteye flounders" because most species lie on the sea bottom on their left sides, with both eyes on their right sides. The Paralichthyidae are the opposite, with their eyes on the left side. A small number of species in Pleuronectidae can also have their eyes on the left side, notably the members of the genus Platichthys.
The common ling, also known as the white ling or simply the ling, is a large member of the family Lotidae, a group of cod-like fishes. It resembles the related rocklings, but it is much larger and has a single barbel. This species is unrelated to the pink ling, Genypterus blacodes, from the Southern Hemisphere. The common ling is found in the northern Atlantic, mainly off Europe, and into the Mediterranean Basin. It is an important quarry species for fisheries, especially in the northeastern Atlantic, although some doubts exist as the sustainability of the fisheries. As an edible species, it is eaten fresh, frozen, or dried, but also preserved in lye, while the roe is a delicacy in Spain.
The southern blue whiting is a codfish of the genus Micromesistius, found in the southern oceans with temperatures between 3 and 7 °C, at depths of 50 to 900 m. Its length is commonly between 30 and 60 cm, with a maximum length of 90 cm. Maximum weight is at least 1350 g.
Trisopterus luscus is a seafish belonging to the cod family (Gadidae).
The blue whiting, Micromesistius poutassou, one of the two species in the genus Micromesistius in the family Gadidae, which also contains cod, haddock, whiting, and pollock. It is common in the northeast Atlantic Ocean from Morocco to Iceland and Spitsbergen. It also occurs in the northern parts of the Mediterranean, where it may be locally abundant. Blue whiting also occur in the northwest Atlantic Ocean between Canada and Greenland, but is considered rare. It has a long, narrow body and a silvery underbody. The fish can attain a length of more than 40 cm. The average length of blue whiting caught off the west shores of the UK is 31 cm.
Paranotothenia magellanica), also known as Magellanic rockcod, Maori cod, blue notothenia or orange throat notothen, is a species of marine ray-finned fish, belonging to the family Nototheniidae, the notothens or cod icefishes. It is native to the Southern Ocean. "Maori chief" and "black cod", sometimes used for this species, usually refer to fishes from the related genus Notothenia. Being a perciform fish, it is unrelated to the true cods of the order Gadiformes. This species is commercially important as a food fish.
Gadella maraldi, the gadella or morid cod, is a species of fish in the family Moridae from the warmer waters of the north eastern Atlantic Ocean and the Mediterranean Sea.
