Tackle & technique

Summer flounder
Summer flounder lie half-buried on sand and shell bottom and ambush bait along channel edges, inlet bars and ocean reefs, from a few feet deep in back bays to about 100 feet offshore. Drift with the tide and bounce a bucktail tipped with a squid or fish strip along the bottom. The bigger fish move to ocean reefs and wrecks in late summer, so follow them out.
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.
