Tackle & technique

Black sea bass
Black sea bass hold tight to wrecks, reefs, rock piles and jetties, from 15 feet inshore in late spring to well over 100 feet on offshore wrecks in late fall. Anchor or drift right over the structure and fish a two-hook high-low rig with squid or clam, or bounce a small jig on the bottom. The biggest males sit on the highest relief.
Little tunny
Little tunny travel fast in schools that pin bait against inlets, points, jetties and tide rips, usually within a few miles of shore and often in less than 60 feet. Stay off the school's path, wait for it to surface within range, and cast small metal or epoxy jigs with a fast retrieve. When fish stay down, troll small feathers along bait edges and color changes to find them.
Scup
Scup school over hard and mixed bottom, rock piles, mussel beds, piers and jetties, usually in 10 to 60 feet of water. Fish a high-low rig with small hooks and squid or clam strips on the bottom, and chum with clam to hold a school under the boat. If nothing bites within 15 minutes, move to the next piece of structure.
