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.
Spotted Seatrout
Soft, delicate white flesh with a mild, sweet flavor; low fat and best eaten fresh. A Gulf Coast favorite — excellent pan-fried, baked with Cajun spices, or used in fish tacos.
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.
Spotted Seatrout
The spotted seatrout, despite its name, is a member of the drum family, not the trout family. It inhabits grass flats and estuaries along the Atlantic and Gulf coasts. Males produce a distinctive drumming sound to attract females.
