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.
Scup
Scup school over hard and mixed bottom, rock piles, mussel beds, piers and jetties, usually in 10 to 60 feet of water. Fish a high-low rig with small hooks and squid or clam strips on the bottom, and chum with clam to hold a school under the boat. If nothing bites within 15 minutes, move to the next piece of structure.
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.
