Pollock (or pollack, pronounced the same and listed first in most UK and US dictionaries) is the common name used for either of the two species of marine fish in the Pollachius genus. Both P. pollachius and P. virens are commonly referred to as pollock. Other names for P. pollachius include the Atlantic pollock, European pollock, lieu jaune, and lythe; while P. virens is sometimes known as Boston blues (distinct from bluefish), coalfish (or coley) or saithe.

Both species can grow to 3 ft 6 in (1.07 m) and can weigh up to 46 lb (21 kg). The fish 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. It can be found in water up to 100 fathoms (180 m) deep over rocks, and anywhere in the water column. They have a range from North Carolinamarker up to the Gulf of St. Lawrencemarker. Pollock are a "whitefish". They are an important part of the New Englandmarker and North Atlanticmarker fisheries, though less so than cod and haddock. They spawn in late winter and early spring on Georges Bankmarker, off the New Englandmarker coast.

Other fish called Pollock

There are also members of the Theragra genus that are commonly referred to as pollock. This includes the Alaska pollock or walleye pollock (Theragra chalcogramma) and the rarer Norwegian pollock (Theragra finnmarchica). While related (they are also members of the family Gadidae) to the above pollock species, they are not members of the Pollachius genus. Alaska pollock generally spawn in late winter and early spring on Southeast Bering Seamarker. The Alaskan pollock fishery in the Bering Sea fishery is the largest single-species food fish fishery in the world.

"Pollock is generally cheaper, greyer and more fibrous than Pollack, which is a finer fish." (Norum, B. 2007)


Atlantic pollock is largely considered to be a whitefish, although it is a fairly strongly flavored one. Although traditionally a popular source of food in some countries like Norwaymarker, in the United Kingdom it has previously been largely consumed as a cheaper and versatile alternative to cod and haddock in the West Country, elsewhere being known mostly for its traditional use as "Pollack for puss / coley for the cat." However, in recent years pollock has become more popular due to over-fishing of cod and haddock. It can now be found in most supermarkets as fresh fillets or prepared freezer items. For example, when minced, it is the primary component of fish fingers and Popcorn Fish.

Because of its slightly gray color pollock is often prepared, as in Norway, as fried fish balls or if juvenile sized maybe breaded with oatmeal and fried as in Shetlandmarker. Year old fish are traditionally split, salted and dried over a peat hearth in Orkneymarker where their texture becomes wooden and somewhat phosphorescent. The fish can also be salted and smoked and achieve a salmon-like orange color (although it is not closely related to the salmon), as is the case in Germanymarker where the fish is commonly sold as Seelachs or sea salmon.
