Catfish feed on the bottom and mostly by smell, so the rig matters more than the lure. Three setups cover nearly everything, and the hook choice decides whether you land the fish or gut-hook it.
| Rig | Best for | Sinker | Where |
|---|---|---|---|
| Slip sinker (Carolina) | Channels and blues, general bottom fishing | 1/2–3 oz egg or bank | Lakes, rivers, any bottom |
| Santee rig | Current, keeping bait off the bottom | 1–4 oz bank sinker | Rivers with flow |
| Float rig | Suspended fish, shallow water, kids | None — bobber only | Ponds, creek mouths |
The slip sinker rig is the workhorse. An egg or no-roll sinker slides freely above a swivel, so a catfish can pick up the bait and move off without feeling resistance — which is the whole point, because a catfish that feels weight drops the bait.
A Santee rig adds a float above the sinker so the bait hovers just off the bottom, out of the snags and above the silt. It is the standard rig on rivers with current.
Use circle hooks for catfish. A circle hook is designed to slide to the corner of the mouth as the fish swims away, which means:
— Far fewer gut-hooked fish, which matters enormously if you release anything
— No hookset needed. You do not strike — you reel steadily and let the rod load
— Better hold on big blues and flatheads
The trade-off is that you must not set the hook. Striking with a circle hook pulls it straight out of the mouth. Steady pressure only.
Size matters: 5/0 to 8/0 for channels, 8/0 to 10/0 for blues and flatheads. Check the gap against your bait — the hook point must be fully exposed. The Hook Size Selector gives you a starting point.
Bait: cut shad or bluegill for blues and flatheads, chicken liver or dough bait for channels, nightcrawlers for eating-size fish. Fresh bait always beats frozen.
Leader: 30 to 50 lb monofilament or fluorocarbon above the hook, lighter than your main line so you lose the hook rather than the fish. Check the pairing with the line strength chart.
Rod: a medium-heavy to heavy rod with a soft tip, 7 to 9 feet for bank fishing. You need enough backbone to drive a hook through a catfish’s bony mouth.
Tie the terminal end with a palomar knot — it is the strongest common knot at the hook and one of the few that handles a large, thick-shanked circle hook well.
Circle hooks, a selection of sinkers, and a leader you can tie in the dark. That is most of it.
Start here for eating-size channels. The in-turned point does the hooking for you — no strike required.

A catfish rig is mostly a question of how much lead holds and whether the hook suits the bait. Use the sinker weight converter to size the lead to the current, check the hook size chart against the bait you cut, and if you fish heavy mono over rock, the shock leader calculator sizes the leader.
Which hook sits at the end of the rig is a separate decision from how the rig is assembled. The catfish hook guide compares circle, Kahle and octopus hooks by bait and species, and covers what size to use on a Santee rig.
Yes in almost every case. Circle hooks hook fish in the corner of the mouth rather than the gut, which is far better for catch and release and holds well on big fish. The key adjustment is that you do not set the hook — you reel steadily and let the rod load.
Match the hook to the bait and the target fish: 5/0 to 8/0 for channel catfish, 8/0 to 10/0 for blues and flatheads. The hook gap must be wide enough that the point sits fully exposed when the bait is threaded on.
A slip sinker rig has a sliding weight resting on the bottom with the bait beside it. A Santee rig adds a float above the sinker so the bait lifts off the bottom, keeping it out of snags and above the silt — the standard choice in rivers with current.
Just enough to hold bottom and no more. Half an ounce in a calm pond, one to three ounces in a lake, and three ounces or more in a river with real current. Too heavy a sinker makes catfish drop the bait when they feel resistance.
Cut shad or bluegill for blues and flatheads, chicken liver or prepared dough bait for channels, and nightcrawlers for eating-size fish. Fresh bait consistently outperforms frozen, and oily bait such as shad releases more scent into the water.
A Santee rig runs a slip sinker above a swivel with a leader down to a single hook, so the hook has to hold a large bait and set itself when the fish picks it up. A 5/0 to 8/0 circle hook is the standard choice for cut bait and live bait, because it sets in the corner of the mouth without you striking. Use a wide-gap circle hook for chunk bait, or a Kahle or octopus hook if you prefer to set the hook yourself.
Match the hook to the bait rather than to the fish you hope to catch. A 2/0 to 4/0 suits worms and small cut bait for eating-size channel cats, 5/0 to 7/0 handles normal cut bait and live bluegill, and 8/0 and above is for big heads and whole fish when you are targeting flatheads. Circle hooks run one size larger than a J hook for the same bait.

Rig components are specified by published manufacturer data: hook size by the standard numbering system, sinker weight in ounces, and leader material by breaking strain. Catfish rigs are judged more by hook gap and leader abrasion resistance than by total weight, because the fish is usually hooked in heavy cover.
