Tackle & technique

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.
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.
Little tunny
Little tunny travel fast in schools that pin bait against inlets, points, jetties and tide rips, usually within a few miles of shore and often in less than 60 feet. Stay off the school's path, wait for it to surface within range, and cast small metal or epoxy jigs with a fast retrieve. When fish stay down, troll small feathers along bait edges and color changes to find them.
