Wels Catfish
Silurus glanis
The Wels Catfish is one of Europe’s largest freshwater predators, with a long, scaleless body and broad flattened head. Native to large rivers, lakes, and reservoirs, it is now widely introduced beyond its original range.
Identification points
- Very long anal fin running much of the underside of the tail region
- Broad, flattened head with small eyes and a wide terminal mouth
- Long whisker-like barbels, including one pair on the upper jaw and two on the lower jaw
Habitat
Deep slow rivers, backwaters, oxbows, reservoirs, and large lakes with submerged timber, holes, undercut banks, and soft bottoms; often holds near cover in warm water.
Bait notes
Large deadbaits or livebaits (where legal), cut fish, lamprey, eel, perch, and big worms can work well; scented fish strips and oversized soft plastics also take fish.
Behavior
Nocturnal ambush predator that feeds on fish, crayfish, amphibians, waterbirds, and carrion; becomes more active at dusk and during warm, low-light periods.
Caution
Powerful jaws, very large size, and heavy slime make handling hazardous; use a large landing net or sling and fish grippers/cropping gloves. Check local rules, as it is invasive and restricted in some waters.
Fishing notes
Fish deep holes, snag edges, and current seams at night or low light; use heavy tackle, abrasion-resistant leader, and strong hooks because large fish dive hard for cover.
