註釋Harp seals are one of the most abundant of the world's hair seals and have long been an important resource for peoples living on seasonally ice-bound coasts of the North Atlantic Ocean. This book reviews the biology and population dynamics of the harp seal Phoca groenlandica Erxleben, the history of its hunting over several centuries, and its eventual conservation. The author treats the biology of the species as a whole, not only on the coasts of eastern Canada, but also of Greenland and northern Europe, and the history of the hunt in all these regions. Knowledge of the behaviour of pack ice on these coasts gives a background to both the ecology of the seals and the economics of the hunt.
