Cuisine & Edibility

Atlantic Sailfish

Firm, mildly flavored flesh similar to marlin; primarily a catch-and-release sport fish. Edible when smoked or grilled but rarely targeted for food; sport anglers typically release it.

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

Atlantic Sailfish

The sailfish is the fastest fish in the ocean, reaching speeds up to 110 km/h. Its enormous dorsal fin, or 'sail,' can be raised to herd baitfish. When hooked, it performs spectacular tail-walking displays across the water surface.

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.
