Summer Diet of the Bearded Seal (Erignathus barbatus) in the Canadian High Arctic
Stomach contents of 34 bearded seals taken in three High Arctic localities (Grise Fiord, Pond Inlet and Clyde) during the summers from 1978-1980 were examined. At least 12 species of fish were present but sculpins (Cottidae) and arctic cod (Boreogadus saida) comprised the bulk of the diet. Eelpouts...
