Species Overview

Atlantic Salmon

The Atlantic salmon is an anadromous species that migrates from the ocean to freshwater rivers to spawn. Renowned among fly fishers, it is also one of the most important farmed fish species globally.

The wels catfish is the largest freshwater fish in Europe, capable of exceeding 5 meters. Found in large rivers and lakes across the continent, it has been documented beaching itself to catch pigeons. It can live over 80 years.
