Amount and composition of food of cod (Gadus morhua) in the Southern Baltic in 1977-1982

Abstract

Based on total and partial daily coefficient values, the amount and composition of cod food was determined for six consecutive years, from 1977 through 1982. The range and nature of differences between different years with respect to a long-term mean were examined. An attempt is made to find a possible correlation between weight and composition of the food consumed.
