Cuisine & Edibility

Bonefish

Edible but extremely bony flesh; rarely consumed as table fare in modern sport fishing. Almost exclusively caught-and-released; the species is prized for its fighting ability, not flavor.

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

Bonefish

The bonefish is the premier shallow-water flats species, prized by fly fishers for its blistering initial run. Found in tropical shallows worldwide, it feeds by rooting in sand and marl for crustaceans and mollusks.

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.
