Daily Bag Limit: The default bag limit for all “unregulated” species is two fish or 100 pounds per day, whichever is more.

Gear: lures, jigs, feathers, spoons, and plugs

Fishing Tips: Light classes of ocean tackle, plus spinning and baitcasting outfits. For trolling, choose small offshore lures, feathers, spoons, small rigged baits such as Ballyhoo and strips. Deep-diving plugs are also good. Blackfins also can be chummed with live Pilchards or similar small baitfish, and fished for with the same bait, or by casting. Best hard lures are white jigs, tied with bucktail or feathers to provide a larger profile. Flies should be similarly tied—to imi- tate size and color of the live chum.
