DIET OF WEANED PUPS AND SEASONAL VARIATIONS IN BODY CONDITION OF JUVENILE BARENTS SEA HARP SEALS PHOCA GROENLANDICA
A bstract Data on blubber depth, body condition, and diet were collected from young of year and juvenile harp seals ( Phoca groenlandica ) in the Barents Sea in the periods February‐April and June‐October 1990–1997. Harp seal pups feed independently shortly after weaning. In the southern parts of th...
