The catfish rig

A wels catfish rig is built around a heavy lead and a strong trace, because a big cat tests every link. Fish it two ways: a running leger that lets the lead slide while the bait sits on the bottom, or a float paternoster that holds the bait off the bottom on a fixed line. Both end in a strong single hook on a heavy trace.

What it's for

Wels catfish, on or just off the bottom, in big rivers and warm lakes. A wels is the largest freshwater fish most anglers will ever hook, and it pulls hard and dirty for snags. So everything on a catfish rig is stepped up: a heavy lead, a strong abrasion-resistant trace and a big, strong single hook. Two presentations cover the fishing. A running leger lays a bait flat on the bottom for cats feeding low, in deep holes, channels and along snaggy margins. A float paternoster lifts the bait off the bottom, which helps over soft mud or weed and presents a livebait or deadbait at a set height. Whichever you fish, the strong trace is the same and it is not optional.

The rig at a glance

Two versions on one rig. The running leger, read top to bottom: the main line comes from the rod and passes through a heavy running lead, or a run ring carrying the lead, so the lead slides freely on the line. Below it a bead protects the knot, then a strong swivel tied with a Palomar knot. From the swivel hangs the trace, heavy mono or coated braid of 25 to 45 lb, 30 to 60 cm long, and a strong single hook snelled on the end. Bait it with a deadbait, a bunch of worms, squid or a few large pellets. Because the lead runs free, a taking cat feels little resistance until it moves off, then the line tightens to the rod. The float paternoster, read top to bottom: the main line comes from the rod to a large float, set to fish the bait off the bottom. Below the float a strong swivel, tied with a Palomar knot. From the swivel the line runs down to a lead on the very end that anchors the rig on the bottom. A short way up from that lead, the strong trace branches off on a loop or a second swivel and carries the single hook with a livebait or deadbait. The float and the end lead together hold the bait at a set height off the bottom, clear of soft mud or weed, where a roaming cat finds it.

How to build it

  1. Snell the hook on the trace. Tie the strong single hook to one end of the trace, heavy mono or coated braid of 25 to 45 lb, with a snell knot. The snell whips the line down the shank so a big hook sits square and turns into the cat's mouth under load. This trace is the non-negotiable bit: it sits between the cat and your main line.
  2. Tie the swivel and set up the lead. Tie a strong swivel to the other end of the trace, and to the main line, with a Palomar knot. For the running leger, thread a heavy running lead or a run ring onto the main line first, add a buffer bead, then tie the swivel below it so the lead slides free. For the float paternoster, slide the float on the main line first, tie the swivel below it, and add the end lead below the swivel with the hook trace branching off above it.
  3. Bait and set the trap. On the running leger, hook on a deadbait, worm bunch, squid or pellets and lower or cast it to the bottom. On the float paternoster, hook on a livebait or deadbait and set the float so the bait hangs off the bottom at the height you want. Set the rod securely with a strong, set drag or a bite alarm, because the take is hard.

How to fish it

For the running leger, lower or cast the bait to a deep hole, a channel or a snaggy margin, tighten down to the lead, and set the rod with a bite alarm and a set drag. The take is a hard, unmistakable run as the cat picks up the bait and moves off, so let the run develop, then lean into it and turn the fish away from the snags before it buries you. For the float paternoster, set the float so the bait sits off the bottom over soft mud or weed, cast it gently so the bait stays on, and watch the float slide away. With either rig, fish the warm months and after dark, when wels feed hardest. Use strong gear matched to the size the water grows, keep the drag set firm, and be ready to give line to a big fish.

A wels is heavy and powerful and the rig is strong by design, so handle the fish with as much care as the tackle. Use a big landing net or a sling, unhook it in the water or on a wet mat with long forceps, support a large fish fully, and check the local size and keep rules. Use barbless or micro-barb hooks where they are required.

Where this rig works

The catfish rig is for wels catfish wherever they grow large in big rivers and warm lakes. Across the atlas it is fished on the Ebro in Spain, the river that grows the giants below Mequinenza; on the Po Delta in Italy, through the channels and lagoons where the big cats roam; and on the Danube near Budapest, the fast city river that holds good wels. As the atlas grows, every new water that uses a catfish rig will link to this same page.
