A 9-foot catfish was just pulled from Europe’s longest river.
Fisherman Alessandro Biancardi hooked a wels catfish measuring 9.4 feet (2.85 meters) long, the largest ever recorded. It was longer than a bed, heavier than many humans, and so massive that Biancardi said he knew at once he’d hooked a monster.
Wels catfish (Silurus glanis) are Europe’s biggest freshwater fish, but the Po has turned them into something extraordinary. Introduced only two decades ago, they’ve flourished in the river’s warm waters and abundant food supply. In colder northern waters, a 6-foot catfish might be 70 years old. But in the Po, a record-breaker this size is just 20 to 30 years old – growing faster than scientists thought possible.
The Po is now famous for producing giants, but it’s a fragile ecosystem. Climate change and droughts are straining the river, threatening native fish – while invasive predators like the catfish continue to thrive.
After being measured, the monster was released back into the murky waters. Proof that in Europe’s longest rivers, some creatures are growing far bigger, and far faster, than we imagined.
