Species Overview
Black Crappie
The black crappie is a popular panfish found throughout North American lakes and reservoirs. Known for its delicate, sweet-tasting flesh, it is most actively caught during spring spawning when it moves to shallow water near cover.
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.
