Cuisine & Edibility

Common Carp

Dense, moderately fatty flesh with an earthy flavor; improves greatly when sourced from clean, cold water. Central European staple — traditionally braised, fried, or prepared as gefilte fish.

Discus

Not consumed — a prized ornamental aquarium fish known as the 'king of the aquarium' for its disc-shaped body and brilliant colors.

Species Overview

Common Carp

The common carp is one of the most widely introduced freshwater fish globally. Originally domesticated in East Asia over 2,000 years ago, it is a sacred fish in many cultures and the primary target species in European coarse fishing.

Discus

The discus is often called the 'King of the Aquarium' for its disc-shaped body and stunning color patterns. Native to the Amazon floodplains, it requires warm, soft, acidic water and feeds its fry with a mucus secretion from its skin.
