Catfish are one of the most popular freshwater gamefish in North America, with three main species — channel cats, blue cats, and flatheads — each with specific habits that influence how they’re rigged and targeted.
The Core Catfish Rig: Slip Sinker
The slip sinker rig is the foundation of most catfish fishing, especially for channel catfish and blue catfish.
Components:
- Egg sinker or no-roll sinker (1–4oz) on main line
- Plastic bead (protects swivel)
- Barrel swivel (stops sinker)
- 18–24 inch fluorocarbon or monofilament leader
- 2/0–5/0 circle hook
Rigging:
- Thread sinker onto main line
- Add bead
- Tie barrel swivel to main line — Improved Clinch Knot or Palomar Knot
- Tie leader to other swivel eye
- Tie circle hook to leader — Palomar Knot (strongest for the repeated stress of cat fishing)
Why it works: When a catfish picks up the bait, the line slides through the sinker — the fish feels only the weight of the leader and hook, not the sinker. This reduces the chance the fish drops the bait before you can respond.
Santee Cooper Rig (Floating Catfish Rig)
A variation of the slip sinker rig with a foam float on the leader, which lifts the bait off the bottom 6–12 inches.
When to use: When catfish are suspended slightly off bottom, on soft muddy bottom where bait would sink and hide, or when visual presentation above silt helps attract fish.
Build: Same as the slip sinker rig, but add a 1-inch foam peg float to the leader 3–6 inches above the hook. The float keeps the bait elevated.
Three-Way Rig (Drift Fishing)
Used for drift fishing on rivers — the rig stays on the bottom as the current sweeps the bait along the river’s contours, covering water until it finds catfish.
Components: Three-way swivel — main line on top, 12–18 inch sinker dropper on one side, 24–36 inch bait leader on other side.
Build:
- Tie main line to top swivel eye
- Tie 12–18 inch dropper to side eye; attach bank sinker
- Tie 24–36 inch leader to other side eye; attach circle hook
The sinker bumps along the bottom; the bait floats up and back behind it, sweeping through the strike zone.
Species-Specific Notes
Channel Catfish
The most widely distributed catfish. Respond to scent-based baits (stink bait, chicken liver, commercial dip baits). Use the standard slip sinker rig, 2/0–3/0 circle hook, and fish near structure (brush piles, deep holes, creek channels).
Blue Catfish
Much larger than channel cats (20–100lb fish are not uncommon in good blue cat water). Target with fresh cut shad — freshness is critical; day-old bait is significantly less effective. Use 3/0–6/0 circle hooks and 30–50lb main line near deep channels, river ledges, and tailwaters below dams.
Flathead Catfish
Active predators that eat almost exclusively live fish. Rig a live bluegill, large creek chub, or live goldfish on a 5/0–8/0 circle hook. Fish near heavy timber, log jams, and undercut banks. Flatheads are primarily nocturnal — fish at night for best results.
Baiting Guide
| Species | Best Bait | Notes |
|---|---|---|
| Channel cat | Chicken liver, cut shad, stink bait | Use pantyhose to hold liver on hook |
| Blue cat | Fresh cut shad or skipjack | Cut bait 2–3 inches; more scent than whole |
| Flathead | Live bluegill, goldfish, creek chub | 3–6 inch live fish; replace if it dies |
Chicken liver tip: Liver falls off the hook easily, especially when casting. Use a rubber band or wrap in a piece of old pantyhose tied around the hook to keep it secure.
Line for Catfish Rigs
Channel cats: 15–20lb monofilament for most situations. Mono’s stretch absorbs sudden runs from big fish.
Blue cats: 30lb monofilament or 30lb braid with 25lb fluorocarbon or mono leader. Braid’s sensitivity helps detect subtle bites in deep water.
Flatheads in timber: 40–65lb braid — flatheads in heavy structure will break anything lighter on the hookset when they bolt for a log.
