Previous evidence from mark-recapture studies indicates that porbeagles in the north Atlantic are divided into two distinct and isolated populations in the east and west. However, studies of population genetics have found no genetic differences between these populations indicating some level of genetic exchange. This study presents the first record of transatlantic movement by a porbeagle tagged in Ireland and recovered by a Faroese vessel in Canadian waters after more than 10 years at liberty.
