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 cod
Cod hold near coarse, rocky bottom on ledges, banks and wrecks, commonly from 80 to 300 feet in the Gulf of Maine. Drift over the structure with a diamond or cod jig and a teaser fly above it, keeping the jig within a few feet of bottom, or fish clams on a high-low rig. Check the stock area and season before keeping one, because most of the year cod must be released.
