Pollock are also members of the cod family. For years, these spirited, saltwater fish were unappreciated except by sport fishermen. Now, they are eagerly sought as a commercial species in their own right.
Pollock range from southern Labrador to Cape Cod, but are fished primarily in coastal waters and on the offshore banks of the Scotian Shelf, Bay of Fundy and Gulf of Maine.
Deep-bodied with three dorsal and two anal fins, pollock differ from cod and haddock by having a pointed snout and projecting lower jaw. The back is brownish-green, paling to a yellowish smoky-gray or green on the sides, and the belly is silver-gray. The lateral line, like that of cod, is pale, but there are no spots. Fish in the commercial catch range are usually from 1 to 4 kg in weight.
Pollock are principally caught with otter trawls, although other types of gear such as long lines, hand lines and gill nets are also used. Pollock are marketed as Boston Bluefish frozen fillets or frozen breaded items such as portions and sticks.
