Cod is the common name for the demersal fish genus Gadus, belonging to the family Gadidae.[1] 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 is popular as a food with a mild flavour and a dense, flaky, white flesh. Cod livers are processed to make cod liver oil, an important source of vitamin A, vitamin D, vitamin E, and omega-3 fatty acids (EPA and DHA). Young Atlantic cod or haddock prepared in strips for cooking is called scrod. In the United Kingdom, Atlantic cod is one of the most common ingredients in fish and chips, along with haddock and plaice.


At various times in the past, taxonomists included many species in the genus Gadus. Most of these are now either classified in other genera, or have been recognized as simply forms of one of three species. All these species have a number of common names, most of them ending with the word "cod", whereas other species, as closely related, have other common names (such as pollock and haddock). However, many other, unrelated species also have common names ending with cod. The usage often changes with different localities and at different times.

Related species

Cod forms part of the common name of many other fish no longer classified in the genus Gadus. Many are members of the family Gadidae; others are members of three related families within the order Gadiformes whose names include the word "cod": the morid cods, Moridae (100 or so species); the eel cods, Muraenolepididae (four species); and the Eucla cod, Euclichthyidae (one species). The tadpole cod family (Ranicipitidae) has now been placed in Gadidae.

Gadiformes include:

Some fish have common names derived from "cod", such as codling, codlet or tomcod. ("Codling" is also used as a name for a young cod.)

Other species

Some fish commonly known as cod are unrelated to Gadus. Part of this name confusion is market-driven. Severely shrunken Atlantic cod stocks have led to the marketing of cod replacements using culinary names of the form "x cod", according to culinary rather than phyletic similarity. The common names for the following species have become well established; note that all inhabit the Southern Hemisphere.


Fish of the order Perciformes that are commonly called "cod" include:

Rock cod, reef cod, and coral cod

Almost all coral cod, reef cod or rock cod are also in order Perciformes. Most are better known as groupers, and belong to the family Serranidae. Others belong to the Nototheniidiae. Two exceptions are the Australasian red rock cod, which belongs to a different order (see below), and the fish known simply as the rock cod and as soft cod in New Zealand, Lotella rhacina, which as noted above actually is related to the true cod (it is a morid cod).


From the order Scorpaeniformes:


The tadpole cod family, Ranicipitidae, and the Eucla cod family, Euclichthyidae, were formerly classified in the order Ophidiiformes, but are now grouped with the Gadiformes.

Marketed as cod

Some fish that do not have "cod" in their names are sometimes sold as cod. Haddock and whiting belong to the same family, the Gadidae, as cod.


Atlantic cod
The Atlantic cod, Gadus morhua

Cods of the genus Gadus have three rounded dorsal and two anal fins. The pelvic fins are small, with the first ray extended, and are set under the gill cover (i.e. the throat region), in front of the pectoral fins. The upper jaw extends over the lower jaw, which has a well-developed chin barbel. The eyes are medium-sized, approximately the same as the length of the chin barbel. Cod have a distinct white lateral line running from the gill slit above the pectoral fin, to the base of the caudal or tail fin. The back tends to be a greenish to sandy brown, and shows extensive mottling, especially towards the lighter sides and white belly. Dark brown colouration of the back and sides is not uncommon, especially for individuals that have resided in rocky inshore regions.

The Atlantic cod can change colour at certain water depths. It has two distinct colour phases: gray-green and reddish brown. Its average weight is 5–12 kilograms (11–26 lb), but specimens weighing up to 100 kilograms (220 lb) have been recorded. Pacific cod are smaller than Atlantic cod[2][6] and are darker in colour.


Atlantic cod (Gadus morhua) live in the colder waters and deeper sea regions throughout the North Atlantic. Pacific cod (Gadus macrocephalus) is found in both eastern and western regions of the Pacific.[37]

Atlantic cod divide into several stocks, including the Arcto-Norwegian, North Sea, Faroe, Iceland, East Greenland, West Greenland, Newfoundland, and Labrador stocks. There seems to be little interchange between the stocks, although migrations to their individual breeding grounds may involve distances of 200 miles (320 km) or more.

Atlantic cod occupy varied habitat, favouring rough ground, especially inshore, and are demersal in depths between 20 and 200 feet (6.1 and 61.0 m), 80 metres (260 ft) on average, although not uncommonly to depths of 600 metres (2,000 ft). Off the Norwegian and New England coasts and on the Grand Banks of Newfoundland, cod congregate at certain seasons in water of 30–70 metres (98–230 ft) depth. Cod are gregarious and form schools, although shoaling tends to be a feature of the spawning season.

Life cycle

Spawning of northeastern Atlantic cod occurs between January and April (March and April are the peak months), at a depth of 200 metres (660 ft) in specific spawning grounds at water temperatures between 4 and 6 °C (39 and 43 °F). Around the UK, the major spawning grounds are in the middle to southern North Sea, the start of the Bristol Channel (north of Newquay), the Irish Channel (both east and west of the Isle of Man), around Stornoway, and east of Helmsdale.

Prespawning courtship involves fin displays and male grunting, which leads to pairing.[38] The male inverts himself beneath the female, and the pair swim in circles while spawning. The eggs are planktonic and hatch between eight and 23 days, with larva reaching 4 millimetres (0.16 in) in length. This planktonic phase lasts some ten weeks, enabling the young cod to increase its body weight by 40-fold, and growing to about 2 centimetres (0.79 in). The young cod then move to the seabed and change their diet to small benthic crustaceans, such as isopods and small crabs. They increase in size to 8 centimetres (3.1 in) in the first six months, 14–18 centimetres (5.5–7.1 in) by the end of their first year, and to 25–35 centimetres (9.8–13.8 in) by the end of the second. Growth tends to be less at higher latitudes. Cod reach maturity at about 50 centimetres (20 in) at about 3 to 4 years of age.


Adult cod are active hunters, feeding on sand eels, whiting, haddock, small cod, squid, crabs, lobsters, mussels, worms, mackerel, and molluscs.

In the Baltic Sea the most important species are Atlantic cod, herring, and sprat.[39] Many studies that analyze the stomach contents of these fish indicate that cod is the top predator, preying on the herring and sprat.[39][39] Sprat form particularly high concentrations in the Bornholm Basin in the southern Baltic Sea.[40] Although cod feed primarily on adult sprat, sprat tend to prey on the cod eggs and larvae.[41]

Lernaeocera branchialis
A fish with its gills infested with two cod worms

Cod and related species are plagued by parasites. For example, the cod worm, Lernaeocera branchialis, starts life as a copepod, a small free-swimming crustacean larva. The first host used by cod worm is a flatfish or lumpsucker, which they capture with grasping hooks at the front of their body. They penetrate the lumpsucker with a thin filament which they use to suck its blood. The nourished cod worms then mate on the lumpsucker.[42][43] The female worm, with her now fertilized eggs, then finds a cod, or a cod-like fish such as a haddock or whiting. There the worm clings to the gills while it metamorphoses into a plump, sinusoidal, wormlike body, with a coiled mass of egg strings at the rear. The front part of the worms body penetrates the body of the cod until it enters the rear bulb of the host's heart. There, firmly rooted in the cod's circulatory system, the front part of the parasite develops like the branches of a tree, reaching into the main artery. In this way, the worm extracts nutrients from the cod's blood, remaining safely tucked beneath the cod's gill cover until it releases a new generation of offspring into the water.[42][43]

The same chart as above, but showing embedded in light green, the collapse of the Atlantic northwest cod fishery [45]

The 2006 northwest Atlantic cod quota is 23,000 tons, representing half the available stocks, while the northeast Atlantic quota is 473,000 tons. Pacific cod is currently enjoying strong global demand. The 2006 total allowable catch (TAC) for the Gulf of Alaska and Aleutian Islands was 260,000 tons.


Farming of Atlantic cod has received a significant amount of interest due to the overall trend of increasing cod prices alongside reduced wild catches.[46] However, progress in creating large scale farming of cod has been slow, mainly due to bottlenecks in the larval production stage, where survival and growth are often unpredictable.[47] It has been suggested that this bottleneck may be overcome by ensuring cod larvae are fed diets with similar nutritional content as the copepods they feed on in the wild [48][49] Recent examples have shown that increasing dietary levels of minerals such as selenium, iodine and zinc may improve survival and/or biomarkers for health in aquaculture reared cod larvae.[50][51][52][53]

As food

Cod is popular as a food with a mild flavor and a dense, flaky white flesh. Cod livers are processed to make cod liver oil, an important source of vitamin A, vitamin D, vitamin E and omega-3 fatty acids (EPA and DHA).

Young Atlantic cod or haddock prepared in strips for cooking is called scrod. In the United Kingdom, Atlantic cod is one of the most common ingredients in fish and chips, along with haddock and plaice. Cod's soft liver can be tinned (canned) and eaten. Cod is mainly consumed in Portugal, Spain, Italy and Brazil.

Following the early 1990s collapse of Canadian stocks, the Canadian Department of Fisheries and Oceans (DFO) banned fishing for northern (that is, cod to the north and east of the island of Newfoundland, in Northwest Atlantic Fisheries Organization areas JKL) cod in 1992, which caused great economic hardship in Newfoundland and Labrador. The collapse was blamed on cold water, or seals, and it had even been suggested the cod were really still there; only rarely was overfishing acknowledged, or management's role in that.

The DFO partly lifted its ban in 1997, although the International Council for the Exploration of the Sea noted the poor recovery of Canadian cod stocks.[54] In general, depleted populations of cod and other gadids appear to recover poorly when fishing pressure is reduced or stopped.[55]

In 1998, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) listed the Atlantic cod as "vulnerable", a category subsequently rebranded as "special concern", though not as an endangered species. This decision process is formally supposed to be informed by Reports that are commissioned from authors. Dr. Kim N.I. Bell authored the 1998 Status Report for COSEWIC.[56][57] This was the first such report on a commercial fish species in Canada. The potential designation (from Not At Risk to Endangered) was highly contentious because many considered the collapse of Atlantic Cod had resulted ultimately from mismanagement by DFO. The Report (section: Author's Recommendation of Status) therefore discussed at great length the process of developing a recommendation for the designation. The Report contained discussion addressing points that had been offered by DFO, because although COSEWIC had a mechanism for the 'jurisdiction', i.e. the department responsible for the 'species' (which is defined for this purpose as, effectively, a population), to provide objections to an author, it had no mechanism for those objections to be objectively arbitrated as a matter of science. Rebuttal by authors was, simply, untraditional and unexpected. That is undoubtedly why, prior to the meeting at which the designation was to be decided, COSEWIC had conducted a massive unannounced edit of the Report, the effect of which was to introduce many errors and change meanings, including removing the word few from "there are few indications of improvement", and expunging a substantial section which engaged various objections raised by DFO. When the unauthorised "edits" were discovered by the author COSEWIC was obliged to circulate a letter explaining that it had sent out a version that lacked the author's approval, and had to provide the author's version to members.[58][59] The Report contained, under a subsection "Designation by geographic management units (as preferred by DFO in 1996)", recommendations (or options) for 10 geographic management units, ranging from Not At Risk or Vulnerable (1 mgmt. area) to Threatened or Endangered (5 mgmt. areas) to simply (i.e. offering no choice) Endangered (4 mgmt. areas). In its designation, COSEWIC firstly disregarded population structure and provided a recommendation based on the presumption of a single homogeneous population (which even DFO's own internal documents concluded was unlikely compared to heterogeneity), and secondly disregarded the arithmetic that clearly put declines in high "at risk" categories and applied a decision of vulnerable, a lower-risk category, to the entire species within Canadian waters. COSEWIC not only provided no accounting for the variance of its designation from the Report recommendation, it did not admit that variance. COSEWIC also refused to release the Report, despite that its rules required it to. Bell, the Report author, subsequently stated[60] that political pressure by the DFO within COSEWIC was what accounted for the difference.

In 2000, WWF placed cod on the endangered species list. The WWF issued a report stating the global cod catch had suffered a 70% drop over the last 30 years, and if this trend continued, the world’s cod stocks would disappear in 15 years.[61] Åsmund Bjordal, director of the Norwegian Institute of Marine Research disputed the WWF's claim, noting the healthy Barents Sea cod population.[62] Cod (known in Norway as skrei) is among Norway's most important fishery exports and the Barents Sea is Norway's most important cod fishery. In 2015, the Norwegian Seafood Council invited Crown Prince Haakon to take part in opening the year’s cod fishing season on the island of Senja.[63]

In 2003, under the new legislative framework of the Species At Risk Act [SARA], COSEWIC placed the Newfoundland and Labrador fisheries cod on the endangered species list and Fisheries Minister Robert Thibault announced an indefinite closure in the Gulf of St. Lawrence and off Newfoundland's northeast coast. In a 2004 report, the WWF agreed the Barents Sea cod fishery appeared to be healthy, but that the situation may not last due to illegal fishing, industrial development, and high quotas.[64] In 2005, the WWF—Canada accused both foreign and Canadian fishing vessels of deliberate, large-scale violations of the restrictions on the Grand Banks, in the form of bycatch. WWF also claimed poor enforcement by NAFO, an intergovernmental organization with a mandate to provide scientific fishery advice and management in the northwestern Atlantic.[65][66]

In 2006, the Norwegian Institute of Marine Research considered coastal cod (but not the North East Arctic cod) endangered, but has since reversed this assessment.[67] In 2010, Greenpeace International added the Atlantic cod to its seafood red list. "The Greenpeace International seafood red list is a list of fish that are commonly sold in supermarkets around the world, and which have a very high risk of being sourced from unsustainable fisheries."[68] According to Seafood Watch, cod is currently on the list of fish consumers should avoid. In the book The End of the Line, it is claimed cod is an example of how unsustainable fishing is destroying ocean ecosystems.[69]

In a letter to Nature in 2011, a group of Canadian scientists reported that cod in the Scotian Shelf ecosystem off Canada are showing signs of recovery.[70]

Cod has been an important economic commodity in international markets since the Viking period (around 800 AD). Norwegians travelled with dried cod and soon a dried cod market developed in southern Europe. This market has lasted for more than 1,000 years, enduring the Black Death, wars and other crises, and is still an important Norwegian fish trade.[71] The Portuguese began fishing cod in the 15th century. Clipfish is widely enjoyed in Portugal. The Basques played an important role in the cod trade, and allegedly found the Canadian fishing banks before Columbus' discovery of America.[72] The North American east coast developed in part due to the vast cod stocks. Many cities in the New England area are located near cod fishing grounds. The fish was so important to the history and development of Massachusetts, the state's House of Representatives hung a wood carving of a codfish, known as the Sacred Cod of Massachusetts, in its chambers.

Apart from the long history, cod differ from most fish because the fishing grounds are far from population centers. The large cod fisheries along the coast of North Norway (and in particular close to the Lofoten islands) have been developed almost uniquely for export, depending on sea transport of stockfish over large distances.[73] Since the introduction of salt, dried and salted cod (clipfish or 'klippfisk' in Norwegian) has also been exported. By the end of the 14th century, the Hanseatic League dominated trade operations and sea transport, with Bergen as the most important port.[74]

William Pitt the Elder, criticizing the Treaty of Paris in Parliament, claimed cod was "British gold"; and that it was folly to restore Newfoundland fishing rights to the French.

In the 17th and 18th centuries in the New World, especially in Massachusetts and Newfoundland, cod became a major commodity, creating trade networks and cross-cultural exchanges. In 1733, Britain tried to gain control over trade between New England and the British Caribbean by imposing the Molasses Act, which they believed would eliminate the trade by making it unprofitable. The cod trade grew instead, because the "French were eager to work with the New Englanders in a lucrative contraband arrangement".[72] In addition to increasing trade, the New England settlers organized into a "codfish aristocracy". The colonists rose up against Britain's "tariff on an import".

In the 20th century, Iceland re-emerged as a fishing power and entered the Cod Wars. In the late 20th and early 21st centuries, fishing off the European and American coasts severely depleted stocks and become a major political issue. The necessity of restricting catches to allow stocks to recover upset the fishing industry and politicians are reluctant to hurt employment.

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 1.8 m (6 ft) long and weighed 96 kg (211 lb), but usually the cod is between 61 cm (24 in) and 1.2 m (4 ft) long and weighs up to 40 kg (88 lb). There is generally no difference in weight or size between sexes of Atlantic Cod.Atlantic cod can live for 25 years, and usually attain sexual maturity between ages two and four, although cod in the northeast Arctic can take as long as eight years to mature fully. Colouring is brown or green, with spots on the dorsal side, shading to silver ventrally. A stripe along its lateral line (used to detect vibrations) is clearly visible. Its habitat ranges from the shoreline down to the continental shelf.

Several cod stocks collapsed in the 1990s (declined by >95% of maximum historical biomass) and have failed to fully recover even with the cessation of fishing. This absence of the apex predator has led to a trophic cascade in many areas. Many other cod stocks remain at risk. The Atlantic cod is labelled vulnerable on the IUCN Red List of Threatened Species.

Cape Cod

Cape Cod is a geographic cape extending into the Atlantic Ocean from the southeastern corner of mainland Massachusetts, in the northeastern United States. Its historic, maritime character and ample beaches attract heavy tourism during the summer months.

As defined by the Cape Cod Commission's enabling legislation, Cape Cod is conterminous with Barnstable County, Massachusetts. It extends from Provincetown in the northeast to Woods Hole in the southwest, and is bordered by Plymouth to the northwest.

Since 1914, most of Cape Cod has been separated from the mainland by the Cape Cod Canal. The canal cuts 7 miles (11 km) roughly across the base of the peninsula, though small portions of the Cape Cod towns of Bourne and Sandwich lie on the mainland side of the canal. Two highway bridges cross the Cape Cod Canal: the Sagamore Bridge and the Bourne Bridge. In addition, the Cape Cod Canal Railroad Bridge carries railway freight and limited passenger services onto the Cape. Cape territory is divided into 15 towns with many villages.

Cape Cod Air Force Station

Cape Cod Air Force Station is a U.S. Air Force station located in the northwest corner of Joint Base Cape Cod, United States, on Flatrock Hill in Massachusetts. It consists of one PAVE PAWS radar station and is in continuous operation.

The facility became operational April 4, 1980 as Cape Cod Missile Early Warning Station, but was renamed Cape Cod Air Force Station on January 5, 1982.The facility became home to the 6th Space Warning Squadron after the closure of the North Truro Air Force Station in North Truro, Massachusetts.

Cape Cod Bay

Cape Cod Bay is a large bay of the Atlantic Ocean adjacent to the U.S. state of Massachusetts. Measuring 604 square miles (1,560 km2) below a line drawn from Brant Rock in Marshfield to Race Point in Provincetown, Massachusetts, it is enclosed by Cape Cod to the south and east, and Plymouth County, Massachusetts, to the west. To the north of Cape Cod Bay lie Massachusetts Bay and the Atlantic Ocean. Cape Cod Bay is the southernmost extremity of the Gulf of Maine. Cape Cod Bay is one of the bays adjacent to Massachusetts that give it the name Bay State. The others are Narragansett Bay, Buzzards Bay, and Massachusetts Bay.

Cape Cod Canal

The Cape Cod Canal is an artificial waterway in the U.S. state of Massachusetts connecting Cape Cod Bay in the north to Buzzards Bay in the south, and is part of the Atlantic Intracoastal Waterway. The approximately seven-mile-long (11 km) canal traverses the narrow neck of land joining Cape Cod to the state's mainland. Most of its length follows tidal rivers widened to 480 feet (150 m) and deepened to 32 feet (9.8 m) at mean low water, shaving 135 miles (217 km) off the journey around the Cape for its approximately 14,000 annual users.Most of the canal is located in Bourne, Massachusetts, but its northeastern terminus is in Sandwich, Massachusetts. Scusset Beach State Reservation lies near the canal's north entrance, the Massachusetts Maritime Academy near its south. A swift running current changes direction every six hours and can reach 5.2 miles per hour (8.4 km/h) during the receding ebb tide. The waterway is maintained by the United States Army Corps of Engineers and has no toll fees. It is spanned by the Cape Cod Canal Railroad Bridge, the Bourne Bridge, and the Sagamore Bridge. Traffic lights at either end govern the approach of vessels over 65 feet (20 m).

The canal is occasionally used by whales and dolphins, including endangered North Atlantic right whales; these can cause closure of the canal.

Cod Wars

The Cod Wars (Icelandic: Þorskastríðin, "the cod wars", or Landhelgisstríðin, "the wars for the territorial waters") were a series of confrontations between the United Kingdom and Iceland on fishing rights in the North Atlantic. Each of the disputes ended with an Icelandic victory. The Third Cod War concluded in 1976, with a highly favourable agreement for Iceland; the United Kingdom conceded to a 200-nautical-mile (370-kilometre) Icelandic exclusive fishery zone after threats that Iceland would withdraw from NATO, which would have forfeited NATO's access to most of the GIUK gap, a critical anti-submarine warfare chokepoint during the Cold War.

As a result, British fishing communities lost access to rich areas and were devastated, with thousands of jobs lost. Since 1982, a 200-nautical-mile (370-kilometre) exclusive economic zone has been the United Nations standard.

The term "cod war" was coined by a British journalist in early September 1958. None of the Cod Wars met any of the common thresholds for a conventional war, and they may more accurately be described as militarised interstate disputes. There is only one confirmed death during the Cod Wars: an Icelandic engineer, who was accidentally killed in the Second Cod War. While he was repairing damage on the Icelandic gunboat Ægir after a collision with the British frigate Apollo, they collided again, on 29 August 1973.Several explanations for the Cod Wars have been put forward. Recent studies have focused on the underlying economic, legal and strategic drivers for Iceland and the United Kingdom, as well as the domestic and international factors that contributed to the escalation of the dispute. Lessons drawn from the Cod Wars have been applied to international relations theory.

Cod as food

This article is about cod and other cod-like fishes from the family of Gadidae, such as haddock, pollock and whiting, regarded as food.

Cod liver oil

Cod liver oil is a dietary supplement derived from liver of cod fish (Gadidae). As with most fish oils, it contains the omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Cod liver oil also contains vitamin A and vitamin D. Historically, it was given to children because vitamin D had been shown to prevent rickets, a consequence of vitamin D deficiency.


A codpiece (from Middle English: cod, meaning "scrotum") is a covering flap or pouch that attaches to the front of the crotch of men's trousers and usually accentuates the genital area. It was held closed by string ties, buttons, or other methods. It was an important item of European clothing in the 15th and 16th centuries, and is still worn in the modern era in performance costumes, for rock music and metal musicians, and in the leather subculture, while an athletic cup protects male athletes in a similar fashion.


Lutefisk (Norwegian, pronounced [²lʉːtfɛsk] in Northern and parts of Central Norway, [²lʉːtəˌfɪsk] in Southern Norway) or lutfisk (Swedish, pronounced [²lʉːtfɪsk] in Sweden and Finland; Finnish: lipeäkala [ˈlipeæˌkɑlɑ]) is a traditional dish of some Nordic countries. It is traditionally part of the Norwegian julebord and Swedish julbord, as well as the similar Finnish joulupöytä.

It is made from aged stockfish (air-dried whitefish) or dried/salted whitefish (klippfisk) and lye (lut). It is gelatinous in texture. Its name literally means "lye fish".

Pollock (pronounced ) 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 both North America and the United Kingdom, while Pollachius virens today is usually known as coley in the British Isles (derived from the older name coalfish). Other names for P. pollachius include the Atlantic pollock, European pollock, lieu jaune, and lythe; while P. virens is also known as Boston blue (distinct from bluefish), silver bill, or saithe.


USS Cod (SS/AGSS/IXSS-224) is a Gato-class submarine, the only vessel of the United States Navy to be named for the cod, named after the world's most important food fish of the North Atlantic and North Pacific.

Her keel was laid down by the Electric Boat Company of Groton, Connecticut on 21 July 1942. The submarine's five diesel engines were built by General Motors' Cleveland Diesel plant located on the west side of Cleveland. She was launched on 21 March 1943 (sponsored by Mrs. G.M. Mahoney), and commissioned on 21 June 1943 with Commander James C. Dempsey in command. Dempsey had already won fame by sinking the first Japanese destroyer lost in the war while in command of a tiny, World War I-era submarine.

She is now permanently moored as a museum ship in Cleveland, Ohio, and is open to visitors.
