Cuisine & Edibility
Discus
Not consumed — a prized ornamental aquarium fish known as the 'king of the aquarium' for its disc-shaped body and brilliant colors.
Muskellunge
Lean, firm white meat with a mild flavor; challenging to prepare due to complex bone structure. Edible when properly filleted — baked or fried — but mostly released by sport anglers.
Species Overview
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.
Muskellunge
The muskellunge, or 'muskie,' is called the 'fish of 10,000 casts' due to its elusive nature. The largest member of the pike family, it is a powerful ambush predator found in clear lakes and rivers of the northern United States and Canada.
