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.
- Common snook
- Snook ambush bait around mangrove shorelines, bridge and dock lights, jetties and the mouths of passes and inlets, generally in 2 to 15 feet of water. Fish moving water, especially the outgoing tide, with a live pilchard, pinfish or shrimp, or a jerkbait or soft plastic swum past the structure. In summer they spawn along beaches and inlets, and in winter they crowd into rivers, canals and deep backcountry creeks where the water stays warmer.
