Dorado - Dorado are king salmon with rotten attitudes and even worse orthodonture!

The "Tigres Del Rio" of the northern pampas are some of the most powerful freshwater fish that can be tackled with a fly rod. The radiant yellow salmon-shaped fish is a fierce, migratory predator with strong jaws, sharp teeth, and is native to northern Argentina, Southern Brazil, and Bolivia.
  Local sportsmen have been rabid dorado anglers for generations, and the quarry has enjoyed an absolute burst of popularity after the recent discovery of a few fisherman-friendly, and exotically attractive clear jungle rivers and marshlands where sight fishing is the rule rather than the exception.
  Dorado are exceptionally strong and range in size from 5 to 50 pounds. The record is 70. These aren't just big fish. They're voracious creatures that hammer topwater flies and attack streamers with reckless abandon. Strikes are violent, followed by immediate, explosive, acrobatic leaps and a relentless series of line-stripping runs.
  Dorado are migratory, spending their entire life in freshwater either spawning or chasing a migratory baitfish the size of a small shad. The predators move into the Tsimane region from May through October and the season peaks in the marshlands of northern Argentina from October through April.

Tsimane Lodge (santa cruz, bolivia)

Tsimane boasts incredible numbers of two species of Dorado up to 40 pounds, Pirapitinga, Amazon Pacú up to 25 pounds, and Yatorana, pound for pound, one of the strongest species swimming in freshwater. This is stream sight-fishing for finned animals that don't belong in water this intimate. Without a doubt, Tsimane is the most exciting new jungle destination on the angling scene in a generation.
  This exotic adventure includes a 5-star hotel stay en route, round trip charter to and between the two lodges and Santa Cruz, and 6.5 days of guided fishing at Asunta and Pluma lodges. Guests fish for three days at each of two spectacular jungle camps with a welcome day of rest and charter flight between the lodges.
