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.
Red drum
Redfish feed on shallow grass flats, oyster bars and marsh edges, often in 1 to 4 feet of water, and drop into channels, deep holes and tidal creeks when the water turns very hot or cold. Work a live shrimp under a popping cork or a soft plastic along the grass line on a rising tide, then fish creek mouths and drains as the tide falls. Bull reds over 30 inches school in the surf, passes and jetties in late summer and fall, where cut mullet or a live crab on the bottom is the standard approach.
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.
