Dorado, also known as mahi-mahi, are large, slender fish that can grow to 3 to 4 feet long and are highly regarded by anglers the world over. This is due largely to the beauty of the fish (the name dorado is Spanish for "golden"), its quality as table fare, and also the acrobatics and excitement of fighting one into the boat.

Dorado are found in tropical and subtropical waters around the world. The fish is usually found in schools near the surface or at middle depths in the oceans and seas. Like tuna, they are warm-blooded fish that travel together in shoals. We've seen such shoals stretch out over kilometers in the Magdalena Bay area. It's quite a sight to see.

During spawning season, dorado gather into large groups called "boils." Spawning takes place in shallow waters – sometimes just a few feet deep – where males fight each other for dominance. Females release eggs that attach themselves to plants and rocks by sticky threads. The male fertilizes the eggs before they sink to the ocean floor or lake bed where they will incubate for several weeks before hatching.

Once hatched, Dorado grow quickly. It is thought that a dorado in the 2-foot length range is only 2 to 3 months old.
