Tackle & technique

Mahi-mahi

Mahi feed near the surface along weedlines, floating debris, buoys and current edges offshore, in water from the low 70s to the low 80s. Troll ballyhoo or small skirted lures along the weed, and when a school comes up behind the boat keep one hooked fish in the water while you pitch cut bait or jigs to the rest. Look for birds working over weed and flotsam.

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.
