Pollock (alternatively and more commonly among anglers spelled as pollack; pronounced /ˈpɒlək/) 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.
The currently recognized species in this genus are:
Both species can grow to 3 ft 6 in (1.07 m) and can weigh up to 46 lb (21 kg). P. virens has a strongly defined, silvery lateral line running down the sides. Above the lateral line, the color is a greenish black. The belly is white, while P. pollachius has a distinctly crooked lateral line, grayish to golden belly, and a dark brown back. P. pollachius also has a strong underbite. It can be found in water up to 100 fathoms (600 ft; 180 m) deep over rocks, and anywhere in the water column. Pollock are a "whitefish".
One member of the genus Gadus is also commonly referred to as Pollock, the Alaska pollock or walleye pollock (Gadus chalcogrammus) including the form known as the Norwegian pollock. While related (they are also members of the family Gadidae) to the above pollock species, they are not members of the genus Pollachius. Alaska pollock generally spawn in late winter and early spring in the southeastern Bering Sea. The Alaska pollock is a significant part of the commercial fishery in the Gulf of Alaska.
