Tackle & technique

King mackerel
Kings roam from beaches and pier ends out to reefs, wrecks and ledges in 40 to 200 feet, usually feeding in the upper half of the water column. Slow-troll live menhaden, blue runners or cigar minnows on a light wire stinger rig, or pull spoons and ribbonfish past bait schools. Look for clean green water above 68 F with bait and birds on it.
Scup
Scup school over hard and mixed bottom, rock piles, mussel beds, piers and jetties, usually in 10 to 60 feet of water. Fish a high-low rig with small hooks and squid or clam strips on the bottom, and chum with clam to hold a school under the boat. If nothing bites within 15 minutes, move to the next piece of structure.
Spot
Spot school over mud and sand in bays, tidal creeks and channels and around piers and bridges, generally in less than 25 feet of water. Fish a two-hook bottom rig with small hooks and bits of bloodworm or shrimp, and move until you find a school. In fall the biggest fish run out of the sounds past piers and inlets, and the bite can go all day.
