Species Overview
Channel Catfish
The channel catfish is the most abundant and widely fished catfish species in North America. It has a keen sense of smell, with taste buds distributed across its entire body, enabling it to locate food in murky water.
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.
