Cuisine & Edibility

Blue Marlin

Firm, mildly flavored meat with moderate fat; often used in Hawaii as smoked marlin or grilled steaks. A prized sport catch; consumption is moderate due to Vulnerable status.

Critically Endangered — consumption is illegal throughout its range. Historically prized for its delicate flesh and black caviar; now one of the world's most threatened fish species.

Species Overview

Blue Marlin

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.
