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.
Haddock
Haddock feed on gravel, sand and clay bottom along the edges of banks and ledges, mostly in 120 to 400 feet. They have small, soft mouths, so fish clam or squid on small hooks on a high-low rig, or a light jig with teasers, right on the bottom. Set the hook gently and keep steady pressure on the way up.
