Cuisine & Edibility

European Sturgeon

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.

Swordfish

Dense, meaty flesh with a mild, slightly sweet flavor; moderate fat and steak-like texture. Ideal for grilling, broiling, or searing; pairs well with lemon-herb or citrus salsas.

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.

Swordfish

The swordfish is a highly migratory pelagic predator recognized by its long, flat, pointed bill. It can dive to depths exceeding 2,800 meters and possesses a specialized organ that heats its eyes and brain for improved vision in cold, deep water.
