Tackle & technique
- Winter flounder
- Winter flounder spend late winter and spring on mud and sand bottom in harbors, coves and tidal channels, often in 5 to 30 feet. Anchor, chum with crushed clams or mussels, and fish small long-shank hooks with worm or clam on the bottom, tapping the rig to stir up mud. The bite is light, so use a sensitive rod.
- 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.
