How to Rig for Southern Flounder

Paralichthys lethostigma

Southern flounder live in bays, marshes, and tidal creeks from the Carolinas through the Gulf, even moving up into brackish and fresh river mouths. They lie flat along drop-offs, creek mouths, and dock edges waiting for baitfish to wash past on the tide. Fall is the key season, when fish migrate toward inlets to spawn offshore.
