A member of the cod family, Pollock is the most important groundfish species in
the world, producing global catches of 6 million tons per year. Two-thirds of
the world's pollock comes from Russia and Asia. Nearly all the rest comes from
Alaska. A change in the Russian fishery from supplying domestic markets to
supplying international markets has made it the biggest global supplier of
pollock. Alaska pollock congregate on the outer shelf and slope of the Bering
Sea, between the Eastern Aleutians and Pribiloff Islands, in depths of 200 to
600 ft. Large harvests are also made along the eastern coast of Russia
(especially the Sea of Okhotsk, between mainland Russia and the Kamchatka
Peninsula) and south to the Sea of Japan. Smaller stocks occur off western
Canada and in the Gulf of Alaska. They are harvested by longliners and small
trawlers that deliver an iced product to motherships or shoreside processors,
and by larger trawlers that process pollock at sea.
