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.
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.
Striped bass
Striped bass feed where moving tide pushes bait past structure: inlets, points, jetties, bridge pilings and rips in the surf, usually in 2 to 40 feet of water. Fish dawn, dusk and night hardest, casting plugs, bucktails and soft plastics or drifting live bunker and eels, and chunk bait on the bottom in current. In midsummer the larger fish drop deeper or feed mostly after dark.
