Golden Dorado in the Bolivian Amazon By Kirk Deeter
This September I joined the Jungle Anglers (six guys from Argentina and one from Brazil) on a gritty, exhausting expedition to find giant freshwater dorado deep in the shadows of the Bolivian jungle. To get there, we traveled first over land, then by small plane, and finally poled dugout canoes up the Rio Secure, one of the many headwaters in the Amazon River basin.
Until recently, few people knew these fish even existed here. Golden dorado are native to the Rio de la Plata River system, which is further south, most notably in Argentina, and does not connect to the Amazon. But some prehistoric flood must have stranded them in these waters, and here they mix with hundreds of species, from pirapitinga (relatives of piranhas) to giant moturo catfish. Until we arrived, only the Indians knew how many big dorado lived in this hidden river basin.
