Pollock

A pollock is a marine fish that belongs to the cod family. The term "pollock" most commonly refers to two species: the Alaska Pollock (Gadus chalcogrammus) and the Atlantic Pollock (Pollachius virens). They are known for their mild flavor and are one of the most commercially important fish species in the world.

Pollock are slender fish with a greenish-brown to silvery-gray body. They have three dorsal fins and two anal fins. A key distinguishing feature of the Atlantic Pollock is a dark lateral line that runs along its side, while the Alaska Pollock is identified by its small, whisker-like barbel on its chin.

Both species of pollock are found in cold, temperate waters. The Alaska Pollock inhabits the northern Pacific Ocean, particularly the Bering Sea, while the Atlantic Pollock lives in the northern Atlantic. They are carnivorous and feed on a variety of smaller fish, crustaceans, and plankton. They are a schooling fish, often forming large, dense groups.

Pollock is one of the world's most heavily fished species. The Alaska Pollock, in particular, is the largest food fish fishery globally. Its mild, white flesh is a key ingredient in many processed seafood products, including surimi (imitation crab meat), fish sticks, and fish fillets sold in fast-food restaurants.
