Tagging and recoveries of grey seals Halichoerus grypus in north Norway and on the Murman Coast, Russia
A total of 787 grey seal pups were tagged between Vestfjorden in North Norway and the White Sea in North West Russia from 1989 to 1994. A majority of them (542) were tagged at the Ainov archipelago on the Murman coast. Thirty-six ( 4.6 %) of the tagged seals were recovered, almost all taken as bycat...
