During the past 10 years a long term survey of the ichthyofauna of southeastern Peru has been carried out, especially at the Tambopata Reserved Zone, Manu National Park and National Sanctuary of Pampas del Heath. Different habitats belonging to distinct types of waters at different elevations (200-900 m) and associated with various aquatic vegetation are described. Sampling time and effort were not equal for each area, being larger for Manu than Tambopata or Pampas del Heath; species number recorded were respectively 174, 140 and 102. The ichthyofauna is dominated by the Ostariophysi (80%). About 60% of the species are found in the three areas; the differences in faunal composition are related to those species of small size and those found in torrential waters in the upper courses versus those from black, still waters in the lowlands. The hypothesis is that, with equal collecting effort, the species number probably will be higher in the Pampas del Heath, than Manu or Tambopata.
