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.
Atlantic tarpon
Tarpon roll along beaches, in passes and channels, and under bridges from late spring through fall, and in South Florida some fish stay through winter in warm canals and backcountry rivers. Live crabs, mullet or pinfish drifted through a pass on the outgoing tide, or a fly or soft plastic cast ahead of a rolling string of fish, are the main approaches. Use a long heavy leader, bow to the jumps, and keep big fish in the water for release.
