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.
Bluefish
Bluefish travel in size-sorted schools and feed where tide pushes bait past structure: inlet mouths, rips, shoal edges and the surf line, mostly in water shallower than 60 feet. Look for birds and breaking bait and cast metal or poppers into it, or soak cut bunker or mullet on the bottom from the beach. Use a short wire or heavy leader because their teeth cut light line.
