Diet of harp seals (Phoca groenlandica) feeding between the breeding and moulting seasons in the southern Barents and White Seas
The harp seal Phoca groenlandica is the most abundant seal species in the Barents Sea. In order to evaluate the ecological importance of the species, diet studies have recently been carried out at various times of the year. In 1992, data were collected from seals sampled between the breeding and mou...
