The diet and foraging behaviour of nine individual Baltic ringed seals ( Phoca hispida botnica Gmelin, 1785) in the Bothnian Bay were studied by combining results from stable isotope analyses (δ 13 C and δ 15 N) with data on intestinal parasites whose occurrence varied among the fish hosts. The patt...
