Description
Summary:Polar cod stomachs collected during autumn of 1986-1988 in the Barents Sea were analysed. The results indicated that polar cod is an opportunistic feeder, and that the observed changes in feeding pattern from one region to another, is in accordance with prey availability in a particular region. The consumption increased with increasing polar cod length through an increase in prey size, rather than in the number of prey. The mean index of stomach fullness in the Northeastern part, reveal a high feeding activity in the Arctic water.
