Tackle & technique

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.
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.
Crevalle jack
Jacks roam in schools through inlets, passes, bays, river mouths and along beaches, pushing bait to the surface, and big fish also hold on nearshore reefs and wrecks. Watch for birds and surface blowups, then cast a popper, a spoon or a bucktail into the school and retrieve fast. Bring heavy spinning tackle, because a jack over 15 pounds runs hard and fights for a long time.
