North Pacific Groundfish Diet Composition Maps

Diet composition maps are presented for three key groundfish predators: Pacific cod (Gadus macrocephalus), walleye pollock (Theragra chalcogramma), and arrowtooth flounder (Atheresthes stomias). Diet composition was calculated by station from samples collected during NMFS summer surveys. Diet Compositon Maps.

Diet composition of groundfish collected during NMFS summer surveys of the eastern Bering Sea, Gulf of Alaska and Aleutian Islands are presented at here. Diet compostion in presented by predator, year and region.

Life History Database

A database of life history characteristics of Alaska groundfish, as determined by extensive literature review, is now available to the public at http://access.afsc.noaa.gov/reem/LHWeb/index.cfm. These life history parameters will be a key to developing the next generation of multispecies models.
