Species Overview
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.
Peacock Bass
The peacock bass is the crown jewel of Amazon basin sport fishing. Despite its name, it is actually a large cichlid. Known for explosive topwater strikes and powerful, drag-screaming runs in tropical rivers and lagoons.
