SC Species Regulations for Red Drum
Saltwater Fishing License required.
Limit: 3 per person per day.
No fish may be taken in federal waters; 15-inch TL minimum, 23-inch TL maximum; May be taken only by rod and reel year-round, by gigging March to November; Designated State Gamefish: fish caught in South Carolina waters may not be sold.
Red Drum (Sciaenops ocellatus)
Iridescent silver-gray with a copper cast, darker above; one or more oscillated spots on upper sides from below soft portion of dorsal fin to base of caudal fin. Mouth inferior and horizontal, teeth set in bands on both jaws. Chin without barbels, smooth pre-opercular margin.
18 inches, 2.6 pounds;
South Carolina State Record: 75 pounds (1965);
maximum age: approx. 38 years (a few individuals as old as 60 have been reported in other states).
Juveniles: Inhabit estuaries near shallow tidal creeks and salt marshes, commonly at marsh grass edges or in the vicinity of oyster reefs; reside in deeper river channels during winter. Subadults inhabit larger tidal creeks, rivers, and the front beaches of barrier islands.
- Adults mature by 3 – 5 years of age; approximate length at maturity: males – 28 inches, females – 33 inches.
- Spawn during late summer and fall. Spawning aggregations occur near estuary inlets and passes along barrier island beaches. Males produce drumming sounds using muscular contractions to vibrate the swimbladder, to attract females.
- Larval red drum use vertical migrations to ride high salinity tidal currents into tidal creeks and shallow salt marsh nursery habitats.
- All sizes of red drum are predatory foragers on or near the bottom; inshore foraging (juveniles) typically occurs at marsh grass edges.
- Adults: Feed primarily on menhaden, spot, anchovies, blue crab, and speckled crab.
- Juveniles: Feed on opossum shrimp, grass shrimp, juvenile spot, and mud minnows, mud crabs, and fiddler crabs. Subadult diet is similar to adult fish. Larvae feed primarily on zooplankton and small invertebrates.
Availability/Vulnerability to Harvest
- Present in South Carolina waters year-round. Distribution is predominantly temperature dependent: juvenile fish progress from marshes and tidal creeks to overwinter in deeper inshore waters; larger adults overwinter offshore and return to nearshore waters during spring.
- No commercial red drum fishery currently exists in South Carolina; potential for recreational harvest is significant since legal size fish inhabit inshore and nearshore waters during a large portion of the year.
- Conservation concerns: degradation and loss of estuarine habitats; lack of information on South Carolina spawning locations; maintenance of optimal numbers of subadult and spawning size fish.
Abundance of Species
Most red drum caught in the SCDNR trammel net survey are between 9 and 30 inches (the current slot is 15-23 inches) and are younger than 4 years old. Therefore, abundance presented here is heavily influenced by successful recruitment. Bigger fish become mature and move into deeper waters, where they might live for 20 or 30 years. A separate long-line survey is used to study these older fish. More Information.
Recreational red drum total catch has been cyclical over the last 30 years based on varying factors that include year-class strength, changes in regulations, and increased fishing pressure. There has been an increase in total catch in South Carolina since 2002. This is reflected in the recent 10 year average total catch being higher than almost all years prior to 2003. While increases in the population of red drum may be contributing to this increase, increased fishing effort by recreational anglers is likely playing a much larger role in the relative increase in recreational landings. One point to note is the increase in fish released alive since 2003 indicating changes in angler behavior. More Information.
