Golden Dorado - Salminus brasiliensis

The Golden Rocket of South America

The Dourado (or Dorado) is one of South America’s most iconic and revered gamefish. Renowned for its dazzling golden scales, voracious feeding behavior, and acrobatic fights, this apex predator inhabits swift rivers of the Paraná, Paraguay, and Uruguay basins. Its name—Salminus—hints at a salmon-like lifestyle, and indeed, the dourado’s aggressive strikes, blistering runs, and leaping ability make it a favorite among freshwater anglers.

Adult dourado are powerful ambush predators, often found in fast, oxygen-rich waters where they hunt shoals of smaller fish like sabalo. Their powerful jaws are lined with sharp teeth capable of shredding baitfish—and poorly prepared tackle. Dourado are known for explosive surface attacks, which adds to their legendary status in South America’s sportfishing world.

Though they do not naturally inhabit the Amazon Basin, Acute Angling guests targeting golden dorado do so on specialized trips in the southern reaches of Argentina.
