Species Overview

Aguja azul

The blue marlin is the pinnacle of big-game fishing. Found in tropical and temperate Atlantic and Indo-Pacific waters, it can exceed 500 kg and is known for spectacular aerial displays when hooked.

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.
