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.
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.
