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.
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.
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.
