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.

سمك الجاحظ

The walleye is the largest member of the perch family and the most sought-after freshwater food fish in North America. Its reflective eyes give it exceptional low-light vision, making dawn and dusk prime feeding times.
