Dorados

Dorados is the common name used for the dolphinfish (Coryphaena hippurus), a tropical and warm-temperate pelagic fish. It is widely marketed as dorado in Spanish-speaking regions and as mahi-mahi in Hawaiian and other markets. The name reflects the fish’s bright coloration, especially in adults, and its perceived golden appearance.

Distribution and habitat: Dolphinfish occur in warm oceanic waters worldwide, in the Atlantic, Indian, and Pacific Oceans. They are primarily surface-dwelling but can dive to several tens of meters. They often appear around floating objects, weed lines, and sargassum, and undertake long migrations between feeding areas and spawning grounds.

Description: The dolphinfish has an elongated, laterally compressed body with a long, high first dorsal fin. Coloration changes with age and mood: juveniles are bluish-green with iridescent spots, while adults take on a vivid golden color with a greenish back. They are fast, strong swimmers and can reach substantial sizes, typically up to about 1.5 meters in length and weights around 15 to 20 kilograms, though larger individuals are known.

Biology and ecology: They feed on squid, smaller fish, and crustaceans. Dolphinfish exhibit rapid growth and reach sexual maturity relatively young. They are highly migratory and commonly form loose schools or pair during certain life stages, depending on food availability and environmental conditions.

Human use and conservation: Dorados are valued for sport fishing and commercial catches. Their flesh is white, firm, and mild in flavor, widely used in cuisines around the world. The species is listed as Least Concern by the IUCN, though regional stock assessments inform management plans to ensure sustainable harvest.
