Food and feeding patterns of cod (Gadus morhua L.) and beaked redfish (Sebastes mentella Travin) were considered for the period 1981–88. Cod feeding intensity increased in spring–summer. Hyperiids formed a major part of young cod diet while juvenile beaked redfish and shrimp were the most important in adult fish. Beaked redfish feeding intensity increased in the summer as the zooplankton biomass increased. The consumption of zooplankton consisted primarily of the copepod Calanus finmarchicus. The annual amounts of hyperiids consumed by juvenile beaked redfish and the beaked redfish juveniles con-sumed by adult cod were estimated.
