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.
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.
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.
