The Wels Catfish World Record
The current all-tackle world record for Wels catfish (Silurus glanis) stands at 297lb 9oz — caught from the Po Delta in Italy in 2010. The fish measured 8ft 9in in length and remains one of the most extraordinary freshwater catches ever recorded.
According to the IGFA world records, Wels catfish are among the largest freshwater fish on the planet. The European record has been broken multiple times over the past two decades as fish in rivers like the Po and Ebro continue to grow in conditions they've never experienced before.
But here's what most UK anglers don't know: the River Ebro in Spain holds fish that genuinely challenge these records. The current Ebro river record stands at 252lb — and fish in the 200lb+ bracket are caught every single season on the Caspe stretch.
How Big Do Ebro Catfish Actually Get?
The short answer: bigger than you're expecting.
The Wels catfish was introduced to the Mequinenza Reservoir on the River Ebro in 1974. In the fifty years since, with warm water, abundant food, and relatively low fishing pressure, the population has grown to include some of the largest freshwater fish in the world outside of South America and Southeast Asia.
Here's what you can realistically expect on a guided session at Caspe:
- Average guided catch: 50–100lb
- Common on any given week: 100–130lb fish
- Regular captures every season: 150–180lb
- Occasional monsters: 200lb+
Fish over 100lb are not special occasions on the Ebro — they're a normal week. The first time a UK angler lands a genuine 100lb river catfish, it recalibrates everything they thought they knew about freshwater fishing.
What Makes the Ebro Produce Such Large Fish?
Several factors combine to make the River Ebro uniquely capable of producing record-class catfish:
Water temperature: The Ebro in Aragón runs warm — summer temperatures in the high 20s°C create near-perfect conditions for cold-blooded fish to feed heavily and grow fast. Compare this to UK waters where catfish barely feed for five months of the year.
Food availability: The Ebro is rich in prey — carp, zander, barbel, crayfish, mussels, and smaller catfish all form part of the diet of large Wels. Fish that eat other fish grow faster and larger than fish restricted to invertebrates.
Longevity: Wels catfish can live for 50–80 years. A fish that's been growing in the Ebro since the 1980s has had four decades of warm water and abundant food. The mathematics of that growth are extraordinary.
Low mortality: Catch and release is standard practice on the Ebro. Fish that might have been killed in other fisheries have been returned and continued growing for decades. The record-class fish that swim in the Ebro today are the product of fifty years of catch and release combined with ideal growing conditions.
The Ebro vs the Po — Which Produces Bigger Fish?
The River Po in Italy currently holds the world record and produces fish at similar sizes to the Ebro. The two rivers are the undisputed top two catfish destinations in Europe.
The difference for UK anglers:
- Accessibility: The Ebro is 2–2.5 hours from UK airports direct. The Po Delta requires a longer journey.
- Infrastructure: The Ebro has a well-established guide infrastructure built up over thirty years. Guided operations are experienced, English-speaking, and set up for UK anglers.
- Combined species: The Ebro also produces exceptional carp fishing alongside the catfish. The Po is primarily a catfish destination.
- Climate: Both rivers offer warm weather, but the Ebro's position in inland Aragón means hot, dry summers that UK anglers tend to find more manageable than the humid Po Delta.
For UK anglers chasing a genuine shot at a record-class fish, the Ebro at Caspe is the most accessible option on the planet.
Your Realistic Chances of a 200lb Fish
Honest answer: it's possible, but not guaranteed on any given trip.
200lb+ fish exist on the Caspe stretch and are landed every season. Your chances increase with:
- Timing: Late spring and early autumn produce the largest fish most consistently
- Session length: A 7-night trip gives you significantly more shots than a 3-night trip
- Guide experience: Local knowledge of where the biggest fish hold is the single biggest factor
On a 7-night guided trip in April or October, your chances of encountering a 150lb+ fish are realistic. A 200lb fish is always possible — and that possibility is real enough that it keeps serious specimen hunters coming back to the Ebro year after year.
