The dorado fish is native to the waters of the Indian, Atlantic, and Pacific Oceans. They inhabit subtropical and tropical waters, which means you can find them in freshwater basins and rivers.

In fact, the largest known dorado, caught in Costa Rica in 1976, was said to have weighed in at 87 lbs. Most dorado caught nowadays will be between 15 and 30 lbs., but adult dorado can well be above 50 lbs.

What Makes Dorado Unique?

These sport fish have a long and slender build that provides them stealth and the ability to move in bursts of high speed during hunting.

Female dorado fish have rounded heads while the male dorado, called “bulls,” have protruding foreheads that go above the upper body, giving the dorado fish one of its distinctive features.

Their coloration is as interesting as their speed. You will see a vibrant greenish sheen on the back while the lower part of the body is a mix of gold and silver. The golden, greenish-blue iridescence that you see is due to the pigmented cells called chromatophores that are linked to the dorado’s nervous system.

That’s why the dorado is considered such a spectacularly beautiful fish. When out of the water, the dorado fish will undergo numerous color changes. Once dead, their golden skin turns yellowish-gray.

What Does Dorado Eat?

Dorados have a diverse diet and will eat anything. They hunt using their strong eyesight and speed. Known as opportunistic predators, they are known to feast on large schools. Crabs, mackerel, flying fish, tuna, and even baby turtles have been known to be part of the dorado diet.
