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.
