The Ice Lover: Biology of the Harp Seal ( Phoca groenlandica )
The number of harp seals, Phoca groenlandica (Erxleben 1777) may now range from 2.25 million to 3 million. The total population is divided among three separate breeding stocks in the White Sea, the Greenland Sea, and the Northwest Atlantic. The continued exploitation of the Northwest Atlantic stock...
