Tackle & technique

Southern flounder
Flounder lie half buried on soft bottom along marsh edges, creek mouths, dock pilings and the sandy sides of passes, usually in 1 to 15 feet of water. Drag a mud minnow or finger mullet on a Carolina rig, or bump a soft plastic slowly along the bottom, and give the fish a few seconds before setting the hook. In fall the adults stack up at passes and jetties on their way offshore, and many anglers gig them at night in knee-deep water.
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.
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.
