Pacific cod (Gadus macrocephalus) ranges across the northern Pacific Ocean from California, northward to the Gulf of Alaska, Aleutian Islands, and Bering Sea north to Norton Sound; and southward along the Asian coast to the northern Yellow Sea.
The Bering Sea and Aleutian Islands other flatfish complex has typically included those flatfish besides northern rock sole, yellowfin sole, arrowtooth flounder, Kamchatka flounder and Greenland turbot.
In 2005, Bering Sea/Aleutian Islands (BSAI) rockfish were moved to a biennial assessment schedule with full assessments in even years to coincide with the frequency of trawl surveys in the Aleutian Islands (AI) and the eastern Bering Sea (EBS) slope.
Northern rock sole (Lepidopsetta polyxystra n. sp.) are distributed primarily on the eastern Bering Sea continental shelf and in much lesser amounts in the Aleutian Islands region. Two species of rock sole are known to occur in the North Pacific Ocean.
A report on the status of forage species in the Gulf of Alaska region is prepared on a biennial basis and presented to the GOA Plan Team and the North Pacific Fishery Management Council in even years.
This is a three species stock assessment for walleye pollock (Gadus chalcogrammus), Pacific cod (Gadus macrocephalus) and arrowtooth flounder (Atheresthes stomias), from the Eastern Bering Sea, Alaska.
Kamchatka flounder is a relatively large flatfish which is distributed from Northern Japan through the Sea of Okhotsk to the Western Bering Sea north to Anadyr Gulf and east to the eastern Bering Sea shelf and south of the Alaska Peninsula.
Greenland turbot (Reinhardtius hippoglossoides) is a Pleuronectidae (right eyed) flatfish that has a circumpolar distribution inhabiting the North Atlantic, Arctic and North Pacific Oceans.
"Flathead sole" as currently managed by the North Pacific Fishery Management Council in the Bering Sea and Aleutian Islands represents a two-species complex consisting of true flathead sole and Bering flounder.
