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.
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.
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.
