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.
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.
