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.

Nile Tilapia

The Nile tilapia is the most widely farmed fish species in the world, cultivated in over 120 countries. Originally from Africa, it is a hardy, fast-growing mouth-brooder that thrives in a wide range of environmental conditions.
