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.
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.
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.
