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 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.
