Walleye pollock is a semi-pelagic schooling fish widely distributed in the North Pacific Ocean. Pollock in the central and western Gulf of Alaska are managed as a single stock independently of pollock in the Bering Sea and Aleutian Islands.
Walleye pollock (Gadus chalcogrammus) are broadly distributed throughout the North Pacific with the largest concentrations found in the Eastern Bering Sea.
Walleye pollock (Gadus chalcogrammus) are distributed throughout the Aleutian Islands with concentrations in areas and depths dependent on diel and seasonal migration.
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.
This assessment summarizes and synthesizes climate, biological, and fishing effects on the shelf and slope regions of the Gulf of Alaska, from an ecosystem perspective, and to provides an assessment of the possible future.
