Canadian marine fisheries management differs from its equivalent in New England in many features, which have their roots in the fundamentally different governmental systems either side of the border. Before their collapse in 1993, the Atlantic Canadian groundfish fisheries were subject to science-based, government-centered management focused on catch quotas and license limitation. Individual quotas were little used outside the corporate sector. Since the collapse, a wide variety of initiatives have been tried. In contrast, the lobster fisheries have operated under license and capacity controls, with restricted seasons and minimum sizes to protect small lobsters. Other fisheries in the region have usually seen some combination of these management approaches.
