Habitat

Oilfish inhabit deep offshore waters typically between 100-800 meters depth along continental slopes. Anglers typically encounter them while deep dropping for other species or during nighttime fishing when they rise closer to the surface. They are caught incidentally while targeting tilefish, grouper, or other deep-water species.

Catch one and it is yours
