Pollock can refer to one of two species of fish. The first species (with the scientific name of Pollachius pollachius) is called many names including Atlantic pollock, European pollock, lieu jaune, and lythe. The other species (with the scientific name of Pollachius virens) is referred to as coley, coalfish, Boston blue, silver bill, or saithe. Pollock is considered to be a whitefish as is widely consumed. In Britain, it is sometimes used for fish and chips, as a cheaper alternative to haddock or cod. It is also a common ingredient in fish sticks or in imitation crab meat.

According to Chabad, who received their information from the Orthodox Union, pollock is a kosher fish.

Note: Alaskan Pollock, despite its name, is actually related more to cod than pollock. That being said, Alaskan pollock is also a kosher fish.
