3Alpha Code: GRC Taxonomic Code: 1480400212|
|Scientific Name with Original Description|
|Gadus ogac Richardson, 1836. Fauna Boreal. Americana, 3:246.|
|Head relatively broad, interorbital space 18-25% of head length; Predorsal distance less than about 33% of length.
Colour: generally dark shading to paler ventrally, indistinct spots dorsally and on sides.
|Port Barrow, Alaska to West Greenland; south along Canadian coast to the Miramichi, Gulf of St. Lawrence and Cape Breton Island; a disjunct population in the White Sea.|
|Habitat and Biology|
|Usually lives close to the coast, from 0 to 200 m depth, and is rarely found offshore, in deeper water.|
It tolerates low salinities, but there is no evidence that it enters fresh-waters.
Fish aged 5 to 6 years attain lengths of about 50 cm;seldom lives beyond 9 yearsand rarely exceeds 60 cm total length.
It matures at 3 to 4 years of age and spawns in shallow waters frorn February to May. The eggs sink to the bottom after spawning.
In Greenland waters, the maximum age is about 11 years.
The food of the Greenland cod is very similar to that of the Atlantic cod, and includes capelin, small flounders, polar cod, shrimps, crabs, euphausiids, squids, polychaetes, and echinoderms.
|Reaches about 70 cm; somewhat smaller in the White Sea.|
|Interest to Fisheries|
|Global Capture production for|
(FAO Fishery Statistic)
Presently only of small, local importance. The catch reported for 1987 in the FAO Yearbook of Fisheries Statistics is 4017 metric tons. It used to be rather abundant in coastal waters of Greenland, but the stock has been strongly reduced in recent years. There is probably competition between this species and the Atlantic cod.

|According to Svetovidov (1948) ogac is similar to Gadus marisalbi and Walters (1955) believes they are the same species. Although ogac and Atlantic cod (Gadus morhua) have different habitat preferences, they are sometimes found together and are able to maintain their separate identities.|
