Tackle & technique

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.
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.
