The diet of haddock (Melanogrammus aeglefinus L.) in the Barents Sea during the period 1984-1991
An analysis of the diet of haddock in the Barents Sea based on 9500 stomachs collected between 1984 and 1991 is presented. The analysis was made on a quarterly basis for 10 cm fish length-classes. An overall 27% of the stomachs collected were empty and the average wet weight of the stomach contents...
