Fauna of Croatia - Freshwater fish
In the member's collection
Silurus glanis (Linnaeus, 1758), commonly known as the wels catfish, is one of Europe's largest freshwater fish species. Native to rivers and lakes across central and eastern Europe, including the Danube River basin, it is easily recognised by its long, scaleless body, broad flat head, and distinctive long barbels (whisker-like structures) on its upper jaw.
Wels catfish can grow to impressive sizes—over 2.5 meters in length and weighing more than 100 kg, making them apex predators in their habitats. They feed on a wide variety of prey, including fish, amphibians, birds, and even small mammals, using ambush tactics and powerful suction to capture their food.
Primarily nocturnal, Silurus glanis prefers slow-moving or still waters with deep holes and submerged structures. It has a long lifespan, sometimes exceeding 30 years. Due to its size and strength, it is a popular target for sport anglers.
In some regions outside its native range, the wels catfish has been introduced and is considered invasive, with concerns about its impact on local ecosystems. However, in its native habitats, like the Danube, it plays a vital ecological role as a top predator.
