Habitat
Dorado primarily inhabits large, fast-flowing rivers and freshwater systems in South America, such as the Paraná, Uruguay, and Amazon basins, where they prefer areas with strong currents and structures like rocks or submerged logs. They are also found in connected lakes and reservoirs, thriving in warm, tropical waters with good oxygen levels.
Diet
Prawns, other fish, crustaceans
Behavior
Dorado are typically solitary or form small schools, actively hunting during the day in open waters or near structures. They exhibit aggressive and territorial behavior, especially when feeding, and are known for their explosive jumps and powerful fights when hooked by anglers. These fish are migratory, moving upstream during the rainy season to spawn and feed on abundant prey.
Fishing
As an experienced fishing guide, targeting the Dorado, or Salminus brasiliensis, is a thrilling pursuit that highlights recreational fishing's role in conservation, with license fees funding habitat protection in South America's iconic rivers. Use aggressive techniques like trolling with large, flashy lures or casting spoons and plugs to mimic their prey such as prawns and small fish, as these provoke their explosive strikes in fast currents. Opt for heavy tackle to handle their powerful fights, including 7- to 8-foot fast-action rods, baitcasting or spinning reels with 20- to 30-pound test monofilament or braided line, and strong hooks to secure large baits or lures. The prime season runs from November to March during the rainy season when they migrate and feed actively, with daytime hours being most productive for their hunting behavior. Focus on fast-flowing rivers like the Paraná, Uruguay, and Amazon basins, particularly around structures such as rocks, submerged logs, or deep pools where they ambush prey. The IGFA all-tackle world record stands at 55 pounds 11 ounces, caught in Brazil in 2011, underscoring their impressive size potential. Conservation efforts, including catch-and-release practices and slot limits in certain areas, are effective management tools supported by angler-funded programs that help maintain stable populations and protect these vital waterways from overfishing.
