A domestic fishery for pelagic sharks has been developing in Atlantic Canada since 1990. Landings consist primarily of three species, porbeagle (Lamna nasus), shortfin mako (Isurus oxyrinchus), and blue (Prionace glauca) sharks. A small but increasing quantity is landed as unspecified sharks. Porbea...
