Pacific cod

It has three separate dorsal fins, 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, down to depths of 900 m (3,000 ft; 500 fathoms). It may grow up to 1 m (40 in) in length and weigh up to 15 kg (33 lb). It is found in huge schools.^[3]

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.^[4] Today, ITIS and the Catalogue of Life list Gadus ogac as synonym of G. macrocephalus.^[5]

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.

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 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).^[7]
