Cuisine & Edibility

Corydoras

Not consumed — a small ornamental bottom-dwelling catfish beloved for its peaceful temperament and role as a substrate scavenger in community aquariums.

Sockeye Salmon

Intense, deep-red flesh with a full, robust salmon flavor and high omega-3 content. Excellent grilled, smoked, or canned; its bold flavor stands up to strong seasonings and wood smoke.

Species Overview

Corydoras

The peppered corydoras is a peaceful bottom-dwelling catfish native to South American rivers. It uses its barbels to sift through substrate for food and should be kept in groups of six or more. It can gulp atmospheric air in low-oxygen conditions.

Sockeye Salmon

The sockeye salmon is famous for turning bright red during its upstream spawning migration. Its deep-red flesh is the richest in omega-3 fatty acids of all Pacific salmon species, making it the most valuable commercially.
