How to recognise it
The Dolphin Fish, or Mahi-Mahi, is easily recognizable. It has a long, slender body with a distinctive, blunt head. The coloration is vibrant, featuring a bright blue-green on the back and golden-yellow on the sides. The fish has large, elongated dorsal and anal fins that run nearly the length of its body. The mouth is large, filled with sharp teeth.
This species is often confused with the smaller, less colorful fish known as the Escolar (Lepidocybium flavobrunneum). The key detail that separates them is the Dolphin Fish's vibrant coloration compared to the more muted tones of the Escolar.
Where it lives
The Dolphin Fish is found in warm waters across the globe. In the United States, its range includes the Atlantic Ocean from Florida to New England and the Gulf of Mexico. In the Pacific, it can be found from California to Hawaii. They prefer offshore waters, typically found in depths of 50 to 1,000 feet.
Dolphin Fish are often associated with floating debris, weed lines, and current edges. In summer, they are more prevalent in shallower waters, while in winter, they may move deeper as water temperatures drop.
When it bites
Dolphin Fish are most active from late spring through early fall. They bite best when water temperatures range from 72 to 84 degrees F. Early morning and late afternoon are prime times for fishing, as they are more likely to feed during these hours.
Weather conditions can influence their activity. A passing front can trigger feeding, while strong winds may scatter them. A full moon often enhances their feeding behavior, making them more aggressive.
How to catch it
To catch Dolphin Fish, use a variety of rigs. A common choice is the trolling rig with ballyhoo or small tuna as bait. Use a 6/0 to 8/0 circle hook. Lures such as brightly colored trolling skirts or poppers in blue and yellow can also be effective.
When casting, target floating debris or weed lines. Trolling at speeds of 6 to 10 knots can entice strikes. Work the lure with a steady retrieve, incorporating occasional pauses to mimic injured prey.
Size, age and the table
Anglers typically encounter Dolphin Fish ranging from 20 to 30 inches in length and weighing between 5 to 15 pounds. A trophy Dolphin Fish is generally considered to be over 40 inches or 30 pounds.
They grow rapidly, reaching maturity in about 4 to 5 years. The average lifespan is around 5 years. Dolphin Fish are known for their excellent eating quality, with firm, white flesh that is mild and flaky.
When handling, be sure to keep them cool to preserve quality. For catch and release, use wet hands and minimize air exposure to ensure their survival.
