Section Menu

The Giant Peacock Bass is found in the Rio Negro, Rio Branco, Rio Madeira and Rio Orinoco basins. The definitive scientific name is Cichla temensis. Common names include; 3 barred peacock, the speckled peacock, tucunaré acú or tucunaré paca. This species is the primary target of Amazon sportfishermen and is recognized as the world's most powerful freshwater fish. The map below shows the primary drainages of South America and is centered on the Amazon basin. The red shaded area is a generalized representation of the natural range of the giant peacock bass and its transplantation in Lake Guri.

Map depicting the range of the Amazon Peacock Bass species Cichla temensis.

The ranges shown in the map are based on a combination of information sources; specimen collection locations (of museum specimens) illustrated in a review of the genus Cichla (by Kullander and Ferreira, 2006), catch data from sportfishing activity and observations by Acute Angling. The ranges are estimations based on the river basins known to hold the species and the tributary streams and drainages likely to be included. The ranges are not meant to be definitive descriptions of species limitations. It is likely that some actual ranges may be larger than shown. Transplantations appear as isolated areas in a species' range. Not all transplantations are included. Much exploration, specimen collection and data review still needs to be done to fill in the gaps. The species represented in this map are listed in the color-coded section at the upper right of the map.

The best time to fish for peacock bass and most Amazon exotics is during the falling water phase of the Amazon’s flood pulse. This varies with the location. The natural range of Cichla temensis (the giant peacock bass) in Brazil extends from the lower Madeira basin, through the Rio Negro basin and north into the central Branco basin; roughly a 1200 mile arc through the central Amazon.  In order to maximize our ability to provide fishing during optimal conditions, we move our operations through that arc, following the dropping water from south to north.  We use 3 different operating mechanisms that can access different types of water and move us through the entire central Amazon basin; allowing us to have access to trophy fish throughout our overall season (September through March).  Each of our operations has its own logistical mechanism, letting it maintain position in optimal water levels (thus optimal fishing conditions) at different times in different regions.  So, in short, any date we schedule for each of the operations is at the optimal time in each of the areas it moves into as the season progresses.
