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.
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.
