Tackle & technique
- Spanish mackerel
- Spanish mackerel school along beaches and around inlets, jetties, piers and bridge-tunnel structures, and along tide rips in 5 to 40 feet of water once the water climbs above about 68 degrees F. Troll small spoons or cast metal jigs and retrieve fast, or look for birds diving on bait and cast into the school. FWC calls for a 30 to 60 pound monofilament leader because their teeth cut light line.
- 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.
