Cuisine & Edibility

Mero

Firm, flaky white flesh with a mild, sweet flavor; harvest is heavily restricted or banned throughout most of its range due to Vulnerable status. Catch-and-release strongly encouraged.

Guppy

Not consumed — a tiny ornamental livebearer prized by hobbyists for its dazzling color variations and ease of breeding in the aquarium.

Species Overview

Mero

The goliath grouper is the largest grouper in the Atlantic Ocean. This massive reef dweller can swallow prey whole and produces a distinctive booming sound by contracting its swim bladder to ward off intruders.

Guppy

The guppy is one of the most widely distributed tropical fish, found in freshwater habitats across the Americas. Males display vivid colors and elaborate tail patterns to attract females. They are live-bearers, giving birth to free-swimming fry.
