Dolphin Fish

Dolphin fish, also known as mahi-mahi or dorado, are one of the most exciting and visually striking offshore game fish. Known for their incredible speed, aerial acrobatics, and vibrant coloration, dolphin fish are a favorite among sport fishers targeting pelagic species. Found in tropical and subtropical waters around the world, they are highly prized for both their thrilling fight and excellent eating quality.

Appearance & Size

Dolphin fish are unmistakable with their elongated, laterally compressed bodies, blunt foreheads, and striking colors that range from electric blue and green to bright yellow and gold. These colors often change rapidly when the fish is excited or hooked. They have long dorsal fins that extend almost the entire length of their bodies and deeply forked tails built for speed.

Mahi-mahi grow rapidly, with most caught fish ranging between 5 to 15 kg (11 to 33 lbs), though larger specimens can exceed 20 kg (44 lbs) and reach up to 2 meters (6.5 feet) in length.

Habitat & Behavior

Dolphin fish are pelagic, meaning they inhabit open ocean waters, often near floating debris, weed lines, and FADs (Fish Aggregating Devices). They prefer warm waters (above 20°C) and are commonly found around offshore structures such as current edges, reefs, and near tuna and billfish schools.

These fish are voracious predators, feeding on flying fish, squid, small tuna, and other baitfish. They are highly aggressive and will often strike at fast-moving lures or baits without hesitation. Their fast growth rate and short lifespan (typically 4–5 years) make them an abundant and sustainable target for anglers.

Best Fishing Techniques

Dolphin fish are aggressive feeders and can be caught using a variety of methods:

• Trolling: The most effective method, using small to medium-sized skirted lures, diving minnows, or rigged dead baits such as ballyhoo or garfish. Bright colors like pink, blue, and green work well.
• Casting: When dolphin fish are feeding near the surface, casting poppers, stickbaits, or metal lures can trigger explosive surface strikes.
• Live Baiting: Live baits such as pilchards, slimy mackerel, and flying fish are highly effective, especially when free-lined or fished under a balloon near floating debris.
• Jigging: When schools are found near FADs or deep structures, vertical jigging with fast-moving metal jigs can entice strikes.

Prime Locations & Seasons

Dolphin fish are found in warm oceanic waters around Australia, particularly off Queensland, New South Wales, and Western Australia. They are most common during the warmer months (spring and summer), when water temperatures rise above 22°C and baitfish schools are abundant.

Why Fish for Dolphin Fish?

Dolphin fish are a dream target for sport fishers due to their aggressive strikes, blistering speed, aerial jumps, and stunning colors. They provide non-stop action when found in schools, as multiple fish can be hooked simultaneously. Additionally, their firm, white flesh makes them one of the best-tasting offshore fish, highly valued for fresh seafood dishes. Whether trolling offshore or casting near floating debris, targeting dolphin fish is an exhilarating experience every angler should try.
