What to know

Habitat Distribution

  • Found throughout almost every drainage in South Carolina.
  • They thrive in both rivers with moderate to swift current over rock, gravel, or sandy bottoms and large impoundments.
  • Can colonize coastal waterways due to brackish water tolerance.

Key Locations

  • Major impoundments including Lakes Marion, Moultrie, Wateree, Murray, Greenwood, Monticello, Wylie, and Hartwell, as well as rivers like the Santee, Cooper, Saluda, Broad, Congaree, and Wateree.
  • Top destinations include the Santee Cooper system (Lakes Marion and Moultrie plus the Diversion Canal), Lake Wateree, Lake Monticello, and the Cooper River below Pinopolis Dam.

Specific Spots

  • Outside river-channel bends with mud bottoms in 30-45 feet of water for winter trophy fishing.
  • Rocky channel banks in 15-30 feet in spring.
  • Target deeper structure in summer.
  • Focus on 20-30 foot depths along main channels and creek mouths in fall.
  • Around the thermocline (20-22 feet in summer).

Answers from onWater's species guide.

What are the best lures and bait for Blue Catfish in South Carolina?

Cut skipjack herring, gizzard shad, and blueback herring are top baits for trophy fish. Cut bait chunks ½-¾ inch wide. Live shad for jug fishing. Consider adding small floats about a foot from the hook to lift bait off bottom and disperse more scent.

Winter (December-March): best trophy opportunities with surface temperatures around 36-48°F. Spring (March-May): excellent action as warming water triggers feeding activity. Summer: challenging during spawning (May-July at 70-75°F), but post-spawn action picks up.

How do you catch Blue Catfish in South Carolina?

Heavy Carolina rigs, drift fishing with cut shad over deep structure, anchored setups, drift fishing around the thermocline, jug fishing with live shad at 10-15 foot depths. Use electronics to locate forage concentrations.

What do Blue Catfish eat?

Opportunistic omnivores with one of the broadest feeding spectra known, consuming clams, snails, aquatic insects, freshwater mussels, fish (including gizzard shad, threadfin shad, white perch, and other catfish), plant material, and even items like muskrats and anthropogenic debris.
