Species Overview

Brown Trout

The brown trout is native to European rivers and has been introduced worldwide. Renowned for its wariness and intelligence, it is the ultimate quarry for fly fishers. Larger specimens become nocturnal, feeding primarily on smaller fish.

European Sturgeon

The European sturgeon is a critically endangered anadromous fish that can live over 100 years. Once abundant in European rivers, it is now restricted to a small population in the Gironde estuary. Its eggs are harvested as beluga-grade caviar.
