The '''Pacific cod''' ('''''Gadus macrocephalus''')'' is a species of [[Actinopterygii|ray-finned fish]] in the [[Family (biology)|family]] [[Gadidae]]. It is a bottom-dwelling fish found in the northern [[Pacific Ocean]], mainly on the [[continental shelf]] and [[Continental margin|upper slopes]], to depths of about {{convert|900|m|ft|-2|abbr=on}}. It can grow to a length of a meter or so and is found in large [[Shoaling and schooling|schools]]. They feed on clams, worms, crabs, shrimp, and juvenile fish.<ref>{{Cite web |last=Fisheries |first=NOAA |date=2024-09-06 |title=Pacific Cod {{!}} NOAA Fisheries |url=https://www.fisheries.noaa.gov/species/pacific-cod#:~:text=Pacific%20cod%20school%20together%20and,,%20shrimp,%20and%20juvenile%20fish. |access-date=2024-12-03 |website=NOAA |language=en}}</ref> It is an important [[Commercial fishing|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 [[Longline fishing|hook and line fishing]], [[Fish trap|pots]], and [[Bottom trawling|bottom trawls]]. Fossils have been found in Canada near a Steller Sea lion fossil dating to the Pleistocene. 

==Description==
It has three separate [[dorsal fin]]s, and the [[catfish]]-like whiskers on its lower jaw. In appearance, it is similar to the [[Atlantic cod]]. A bottom dweller, it is found mainly along the continental shelf and upper slopes with a range around the rim of the North [[Pacific Ocean]], from the [[Yellow Sea]] to the [[Bering Strait]], along the [[Aleutian Islands]], and south to about [[Los Angeles, California|Los Angeles]], down to depths of {{convert|900|m|ft fathom|sigfig=1|abbr=on}}. It may grow up to {{convert|1|m|in|-1|abbr=on}} in length and weigh up to {{convert|15|kg|lb|abbr=on}}. It is found in huge schools.<ref name=FAO>[http://www.fao.org/fishery/species/3011/en ''Gadus macrocephalus'' (Tilesius, 1810)] FAO, Species Fact Sheet. Retrieved April 2012.</ref>

Molecular genetic analyses strongly suggest that Pacific cod and [[Greenland cod]] (''Gadus ogac'') from Greenland–Arctic Ocean are the same species and that ''G. ogac'' should be a junior synonym of ''G. macrocephalus''.<ref>{{Cite journal | last1 = Carr | first1 = S.

In the Northeast Pacific catches of Pacific cod by the [[United States]] trawl fishery and joint-venture fisheries increased from less than 1,000 tonnes in 1979 to nearly 91,000 tonnes in 1984 and reached 430,196 tonnes in 1995. Today, catches are tightly regulated and the Pacific cod quota is split among fisheries that use hook and line gear, pots, and bottom trawls.

==Conservation status==
The [[Salish Sea]] population of Pacific cod is a U.S. [[National Marine Fisheries Service]]  [[Species of Concern]], one of those species about which the U.S. government's [[NOAA|National Oceanic and Atmospheric Administration]] has some concerns regarding status and threats, but for which insufficient information is available to indicate a need to list the species under the U.S. [[Endangered Species Act]] (ESA).<ref>[http://www.nmfs.noaa.gov/pr/species/concern/ Species of Concern] [[NOAA]]</ref>
