7 Porbeagle Shark Endangered due to overfishing. Found in northern Newfoundland into the Gulf of St. Lawrence Biggest step taken in prevention of extinction is fishing quotas

8 Conservation of sharks in Canada All recreational fishing for sharks is restricted to catch and live release. All commercial shark fishing quotas are set at levels which maintain or increase population numbers at healthy levels. Sharks caught accidentally in fisheries targeting other species are to be released alive, if they are not landed. The mating ground of porbeagle sharks has been closed to commercial fishing to encourage population recovery.
