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.
Rainbow Trout
The rainbow trout is native to cold-water tributaries of the Pacific Ocean in Asia and North America. Widely introduced worldwide, it is prized by anglers for its acrobatic leaps and beautiful coloration.
