Cuisine & Edibility

Brown Trout

Firm, flavorful flesh ranging from cream to pink; moderately fatty with a richer taste than rainbow trout. Excellent pan-fried, baked, or smoked; highly regarded as a European table fish.

Species Overview

Brown Trout

The brown trout is native to European rivers and has been introduced worldwide. Renowned for its wariness and intelligence, it is the ultimate quarry for fly fishers. Larger specimens become nocturnal, feeding primarily on smaller fish.

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.
