Rio Madeira Basin:The Madeira, like the Solimoes and the Rio Branco carries suspended particulate matter and is not itself a fruitful peacock fishery, but many of its lower tributaries, such as the Igapo Acu, Matupiri and Marmelos provide perfect peacock habitat. These rivers range from relatively clear to lightly stained blackwater and are equally excellent for fly and conventional anglers. They typically produce large numbers of peacock bass, while still offering access to big hulking 20-pounders. This is the place to go if your goal is lots of action with a variety of fishing styles. Under good conditions, these waters will produce 15 to 50 fish per angler per day, yet still provide trophies into the 20 pound class. We usually concentrate on this region in September and October, when water levels are generally perfect. The Rio Madeira basin represents a great balance between quantity and size and is a great place to start a serious peacock bass habit. 

Rio Branco Basin: Fishing in this region generally begins in late November and can continue right into March. Like the Madeira, the Rio Branco itself is not a peacock sportfishery. However, its clear water tributaries, such as the Tapera and Xeriuini produce greater numbers of peacock bass than anywhere else in the Amazon basin. Although peacocks over 20 lbs. are not common here, the area is known for a high proportion of midsize fish with more than enough fish in the high teens to satisfy any fisherman. Anglers here can land as many as 20 to 70 fish per day! The pristine waters in these tributaries drain through the vast biofilter of northern savannah lands. The resultant clear black waters lend themselves to sight fishing and are highly productive for both fly and conventional anglers. When you add in the exceptional beauty of this region, with its small waters, white sand beaches and looming forests, you have the makings of the most idyllic peacock adventure of all.
