Overview: This fishery targets Greenland halibut or redfish (mainly Sebastes fasciatus). The directed deep-sea bottom fishery for Greenland halibut commenced in 1990, whereas the bottom fishery for redfish has been a target of commercial interest for over 40 years in this region (NAFO, 2007a). The fishery for redfish is mainly conducted in Divisions 3M and 3O. Since 1998, no directed fishery for redfish has been authorized in 3L and 3N. Greenland halibut is mainly fished in Divisions 3M and 3L. The redfish fishery is conducted at shallower depths (150–800 m) than the Greenland halibut fishery (600–1 900 m), but the gear type remains roughly the same (e.g. 135-mm bottom trawls) (Power, 2005; NAFO, 2007a).
