Cuisine & Edibility

Brook Trout

Delicate, sweet flesh with a nutty, mild flavor; low fat and fine texture. One of the most prized freshwater eating fish in North America — best pan-fried simply in butter with herbs.

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.

Species Overview

Brook Trout

The brook trout is actually a char, native to cold, clean streams of eastern North America. Its olive-green body with distinctive worm-like markings (vermiculations) and red spots with blue halos make it one of the most beautiful freshwater fish.

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.
