Pollock or pollack (pronounced ) is the common name used for either of the two species of North Atlantic ocean fish in the genus Pollachius. Pollachius pollachius is referred to as "pollock" in North America, Ireland and the United Kingdom, while Pollachius virens is usually known as saithe or coley in Great Britain and Ireland (derived from the older name coalfish). Other names for P. pollachius include the Atlantic pollock, European pollock, lieu jaune, and lythe or lithe;[

] while P. virens is also known as Boston blue (distinct from bluefish) and silver bill.
Species
The recognized species in this genus are:
-
Pollachius pollachius (Carl Linnaeus, 1758) (pollack)
-
Pollachius virens (Linnaeus, 1758) (coalfish)
Description
Both species can grow to .
P. virens can weigh up to
and
P. pollachius can weigh up to .
P. virens has a strongly defined, silvery
lateral line running down the sides. Above the lateral line, the colour 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 deep over rocks and anywhere in the
water column.
As food
Atlantic pollock is largely considered to be a whitefish. Traditionally a popular source of food in some countries, such as
Norway, in the United Kingdom it has previously been largely consumed as a cheaper and versatile alternative to cod and
haddock. However, in recent years, pollock has become more popular due to overfishing of
cod and haddock. It can be found in most supermarkets as fresh fillets or prepared freezer items. For example, it is used minced in
Fishstick or as an ingredient in
Crab stick and is commonly used to make fish and chips.
Because of its slightly grey colour, pollock is often prepared, as in Norway, as fried , or if juvenile-sized, breaded with oatmeal and fried, as in Shetland. Year-old fish are traditionally split, salted, and dried over a peat hearth in Orkney, where their texture becomes wooden. Coalfish 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 Germany, where the fish is commonly sold as Seelachs ("sea salmon").
In 2009, UK supermarket Sainsbury's briefly renamed Atlantic pollock "colin" in a bid to boost ecofriendly sales of the fish as an alternative to cod. Sainsbury's, which said the new name was derived from the French for cooked pollock (colin]]), launched the product under the banner "Colin and chips can save British cod."
Pollock is regarded as a "low-mercury fish" a woman weighing can safely eat up to per week, and a child weighing can safely eat up to .
Other fish called pollock
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
Norway pollock. They are also members of the family
Gadidae but not members of the genus
Pollachius.
