The aim of the seal part of the program was to investigate their food and feeding habits and role as top-predators. In total 1 059 stomachs from grey seals (Halichoerus grypus) (737 had food remains), 799 stomachs from common seals (Phoca vitulina) (493 had food remains), 62 stomachs from hooded seals (Cystophora cristata) (47 had food remains) and 72 stomachs from harp seals (Phoca groenlandica) (39 had food-remains) were obtained. The main food species of grey seals in Icelandic waters ordered in percentage by weight, were cod (Gadus morhua), sand eels (Ammoditdae), catfish (Anarhichas lupus), saithe (Pollachius virens) and lumpsucker (Cyclopterus lumpus).
