Tackle & technique

Winter flounder
Winter flounder spend late winter and spring on mud and sand bottom in harbors, coves and tidal channels, often in 5 to 30 feet. Anchor, chum with crushed clams or mussels, and fish small long-shank hooks with worm or clam on the bottom, tapping the rig to stir up mud. The bite is light, so use a sensitive rod.
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.
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.
