Cape Cod Bay

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 bluefin tuna

Bluefin tuna follow schools of herring, mackerel, sand eels and menhaden over banks, ledges and shoals, mostly in the top 150 feet. Troll spreader bars and daisy chains to find fish, then switch to live bait, chunks or stick baits once a school is located. Heavy tackle and a NOAA HMS permit are required, and size-class limits change through the season.

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.
