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.
- Atlantic croaker
- Croaker feed on mud and sand bottom along channel edges, oyster bars, piers and deeper holes in bays and sounds, mostly in 5 to 30 feet of water. A two-hook bottom rig with small hooks and shrimp, bloodworm or squid catches them from piers, the surf and small boats. Fish the hours around high tide and into the evening.
- Gray triggerfish
- Gray triggerfish hover a few feet over reefs, wrecks and ledges, usually in 60 to 200 feet, and often show up while snapper fishing. Use small, strong circle hooks with small pieces of squid or cut bait on a short bottom rig, because they nibble and strip big baits. Keep the bait just off the bottom and reel steadily at the first solid pull.
