Results from analyses of stomach and intestinal contents from captured seals revealed that the diet was comprised of relatively few prey taxa. The squid Gonatus fabricii and polar cod Boreogadus saida were particularly important, whereas capelin Mallotus villosus, and sand eels Ammodytes spp contributed more occasionally. G. fabricii was the most important food item in autumn and winter, whereas the observed summer diet was more characterized by polar cod, however with important contribution also from G. fabricii and sand eels. The latter was observed on the hooded seal menu only during the summer ...
