Flounder in Charleston Waters

Flounder use sandy and muddy bottom near depth changes, current edges, and structure transitions. Their flat profile and upward-facing eyes suit an ambush strategy close to the bottom.

Charleston abundance is seasonal, with fish moving between estuarine and coastal water. Support larger fish carefully, confirm length before harvest, and follow current gigging and hook-and-line rules.

16-inch minimum TL; 5 per person per day, not to exceed 10 per boat per day. The bag limit applies to hook-and-line or gig harvest. Daylight gigging in salt waters is prohibited.

Regulations can change. Verify current SCDNR rules before fishing.
