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.
Atlantic bluefin tuna
Bluefin tuna follow schools of herring, mackerel, sand eels and menhaden over banks, ledges and shoals, mostly in the top 150 feet. Troll spreader bars and daisy chains to find fish, then switch to live bait, chunks or stick baits once a school is located. Heavy tackle and a NOAA HMS permit are required, and size-class limits change through the season.
