Tackle & technique

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.
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 snapper
Mangrove snapper hold tight to mangrove roots, bridge pilings, jetties and reef ledges, from a few feet deep inshore to 150 feet offshore. Chum to pull them out of cover, then freeline or lightly weight a live shrimp or pilchard on fluorocarbon leader, since they shy away from heavy line in clear water. The bite improves at dusk and after dark.
