Catches of fish are regulated by the European Community, which permits only a small regulated catch for Norway and New Zealand (3). In Canada, a fish shark management plan was developed in the 1990’s (5), which includes measures such as limited fishing licenses, gear, fishing areas and seasons for the porbeagle (3). However, it is uncertain whether these measures to reduce exploitation are sufficient to allow for recovery of the northwest Atlantic population (5). In the United States the porbeagle is currently included in the Highly Migratory Species Fishery Management Plan, and there is an annual quota in place. Except for the New Zealand fishery, there is no regulation on catches of the porbeagle in the southern hemisphere (3).
At present, there is also no regulation of the international trade demand for meat that is driving many fisheries (1). In June 2007, at the meeting of the Conference of CITES Parties in June 2007, a proposal was raised to list the porbeagle under Appendix II, which would mean that trade in this species would be controlled in order to ensure it was compatible with their survival. Unfortunately, the proposal fell short of the votes needed to adopt this listing, leaving this heavily traded species vulnerable to further overexploitation (6).
