'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 'pollock', while ''P. virens'' is sometimes known as Boston blues (separate 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 Carolina up to the
Gulf of St. Lawrence. Pollock are a "
white fish". They are an important part of the
New England and
North Atlantic fisheries, though less so than
cod and
haddock. They spawn in late winter and early spring on
Georges Bank, off the New England coast. The most important pollock fishery is the
Bering Sea fishery of
Alaska.
There are also members of the ''
Theragra'' genus that are commonly referred to as pollocks. This includes the 'Alaska pollock' or 'walleye pollock' (''Theragra chalcogramma'') and the 'Norwegian pollock' (''Theragra finnmarchica''). While related (they are also members of the
family ''Gadidae'') to the above pollocks, they are not members of the ''Pollachius'' genus.
Fisheries
Alaskan pollock is the largest
food fish resource in the world. More than 3 million tons of Alaska pollock are caught each year in the
North Pacific from Alaska to northern
Japan. Alaska pollock catches from U.S. fisheries have been quite consistent at about 1.5 million tons a year, almost all of it from the Bering Sea.
The Alaskan pollock is said to be "the largest remaining source of palatable fish in the world."
[1]. However, the biomass of pollock has declined in recent years, perhaps spelling trouble for both the
Bering Sea ecosystem and the commercial fishery it supports.
Cuisine
Atlantic pollock is largely considered to be a white fish, although it is a fairly strongly flavored one. Alaska pollock has a much milder taste, whiter color and lower oil content.
High quality, single frozen whole Alaska pollock fillets may be layered into a block mold and deep frozen to produce fish blocks that are used throughout
Europe and
North America as the raw material for high quality breaded and battered fish products. Lower quality, double-frozen fillets or minced trim pieces may also be frozen in block forms and used as raw material for lower quality, low-cost breaded and battered
fish sticks, portions, etc.
Single frozen Alaska Pollock is considered to be the premier raw material for ''
surimi''; the most common use of surimi in the United States is "imitation crabmeat" (also known as
crab stick).
Alaska pollock is commonly used in the
fast food industry, for example the fish filet of
Dairy Queen,
Arby's, and
Burger King are also made from Alaska pollock.
McDonald's uses
Hoki and/or pollock in their
Filet-O-Fish sandwich.
