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.
Today, three species in the genus are recognized:
| Image | Common name | Scientific name | Maximum length | Common length | Maximum weight | Maximum age | Trophic level | Fish Base | FAO | ITIS | IUCN status |
|---|---|---|---|---|---|---|---|---|---|---|---|
 | Atlantic cod | Gadus morhua Linnaeus, 1758 | 200 cm | 100 cm | 96.0 kg | 25 years | 4.4 | [4] | [5] | [6] |  Vulnerable [7] |
 | Pacific cod | Gadus macrocephalus Tilesius, 1810 | 119 cm | cm | 22.7 kg | 18 years | 4.0 | [8] | [9] | [10] | Not assessed |
 | Alaska pollock | Gadus chalcogrammusPallas, 1811 | 91.0 cm | cm | 3.85 kg | 15 years | 3.5 | [11] | [12] | [13] | Not assessed [14] |
Modern taxonomy included Alaska pollock (Gadus chalcogrammus), which is genetically not separate from Norway pollock. [15] [16] Greenland cod (G. ogac) that was considered an own species, is considered the same species as Pacific cod (G. macrocephalus). [16] [2] [3]
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.
The Atlantic cod 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, and as cured salt cod or clipfish.
Mackerel is a common name applied to a number of different species of pelagic fish, mostly from the family Scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment.
Pollock or pollack is the common name used for either of the two species of North Atlantic 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. Other names for P. pollachius include the Atlantic pollock, European pollock, lieu jaune, and lythe; while P. virens is also known as Boston blue, silver bill, or saithe.
Herring are forage fish, mostly belonging to the family of Clupeidae.
Sardine and pilchard are common names for various species of small, oily forage fish in the herring family Clupeidae. The term sardine was first used in English during the early 15th century; a somewhat dubious folk etymology says it comes from the Italian island of Sardinia, around which sardines were once supposedly abundant.
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 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. Fossils have been found in Canada near a Steller Sea lion fossil dating to the Pleistocene.
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.
The saffron cod(Eleginus gracilis) is a commercially harvested fish closely related to true cods. It is dark grey-green to brown, with spots on its sides and pale towards the belly. It may grow to 55 cm and weigh up to 1.3 kg.
The rock cod is a temperate fish found off the coasts of southeastern Australia, Tasmania, the Great Australian Bight and northwards up the southwestern Australia coasts. They are also found around the coasts of New Zealand and California. They belong to the family Moridae and are not related to the true cods. They are also known as beardie in Australia.
Sprat is the common name applied to a group of forage fish belonging to the genus Sprattus in the family Clupeidae. The term also is applied to a number of other small sprat-like forage fish. Like most forage fishes, sprats are highly active, small, oily fish. They travel in large schools with other fish and swim continuously throughout the day.
Shrimpfish, also called razorfish, are five small species of marine fishes in the subfamily Centriscinae of the family Centriscidae. The species in the genera Aeoliscus and Centriscus are found in relatively shallow tropical parts of the Indo-Pacific, while the banded bellowsfish, which often is placed in the subfamily Macroramphosinae instead, is restricted to deeper southern oceans.
The Alaska pollock or walleye pollock is a marine fish species of the cod genus Gadus and family Gadidae.
An anchovy is a small, common forage fish of the family Engraulidae. Most species are found in marine waters, but several will enter brackish water, and some in South America are restricted to fresh water.
Plaice is a common name for a group of flatfish that comprises four species: the European, American, Alaskan and scale-eye plaice.
Ilisha is a genus of ray-finned fishes in the family Pristigasteridae. The genus contains 16 species. It is similar to Pellona but lacks a toothed hypo-maxilla. The genus has a worldwide distribution in tropical and subtropical coastal waters and estuaries. Some species also enter rivers, and I. amazonica and I. novacula are largely–if not entirely–restricted to tropical rivers.
Clupea is genus of planktivorous bony fish belonging to the family Clupeidae, commonly known as herrings. They are found in the shallow, temperate waters of the North Pacific and the North Atlantic oceans, including the Baltic Sea. Two main species of Clupea are currently recognized: the Atlantic herring and the Pacific herring, which have each been divided into subspecies. Herrings are forage fish moving in vast schools, coming in spring to the shores of Europe and America, where they form important commercial fisheries.
