The catfish: records broken every year
Since its expansion in France in the 1980s, silurus glanis has kept pushing the limits. This fish, still growing, has colonised major rivers, and records are regularly broken. In 2025, a 2.79-metre specimen was caught in the Tarn at Albi. This freshwater giant fascinates as much as it divides: some see it as a threatening super-predator, others as an exceptional sport fishing opportunity. One thing is certain: its growth potential has not yet revealed all its secrets.
Catfish records in France
Here is the ranking of the biggest catfish caught in France:
| Rank | Length | Est. weight | Location | Angler | Year |
|---|---|---|---|---|---|
| 1 | 2.79 m | 130–150 kg | Tarn (Albi) | Not disclosed | 2025 |
| 2 | 2.75 m | 130 kg | Tarn (Albi) | Toc brothers | 2025 |
| 3 | 2.74 m | ~130 kg | Tarn | Jean-Christophe Conéjéro | 2017 |
| 4 | 2.70 m | ~120 kg | Garonne | Not disclosed | 2022 |
| 5 | 2.65 m | ~110 kg | Rhône | Not disclosed | 2021 |
European records
The world record in public waters is held by Alessandro Biancardi with a 2.85-metre specimen caught in the Po in Italy in 2023. The Ebro in Spain regularly produces specimens over 2.50 metres. The Danube and its tributaries remain the historic cradle of this species in Europe. France ranks 2nd in Europe for records, behind Italy. The Tarn and Garonne rival the best rivers on the continent.
French rivers with giant catfish
Six French rivers concentrate numerous big specimens:
- 1Tarn: Undisputed no. 1, 2.79 m record, deep holes around Albi.
- 2Garonne: The whole middle and lower course, regular 2.50 m+ specimens.
- 3Rhône and Saône: High density between Lyon and Avignon.
- 4Lot: Confluence with the Garonne at Aiguillon, 2 m+ specimens.
- 5Seine: Growing population in Paris and downstream.
- 6Loire: Recent colonisation, huge potential for the years to come.
The Lot–Garonne confluence at Aiguillon is a recognised hotspot for this predator. These deep holes (6–12 m) created by the meeting of the two watercourses concentrate several big specimens.
How big can the catfish grow?
Some biologists estimate that 3 metres represents the theoretical natural limit of the species. Beyond 2 metres, growth becomes very slow: a few centimetres and 5 kg per year. Life expectancy can reach 60 to 80 years in optimal conditions. A 2.85-metre specimen is probably over 40 years old. Warm waters, abundant food and absence of fishing pressure favour reaching these exceptional sizes. The potential in France may not yet be fully realised.
The catfish: super-predator or scapegoat?
This freshwater giant is the subject of controversy in France. Yet several INRAE studies show a varied diet: it does not feed solely on fish. Its real impact on certain local populations is debated. Science indicates that it does not decimate these ecosystems. Responsible catch-and-release practice preserves numerous big specimens while limiting harvests. It is above all a fascinating fish that deserves respect.
