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 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.
- Common snook
- Snook ambush bait around mangrove shorelines, bridge and dock lights, jetties and the mouths of passes and inlets, generally in 2 to 15 feet of water. Fish moving water, especially the outgoing tide, with a live pilchard, pinfish or shrimp, or a jerkbait or soft plastic swum past the structure. In summer they spawn along beaches and inlets, and in winter they crowd into rivers, canals and deep backcountry creeks where the water stays warmer.
