Most of these fishes are contained in the orders Characiformes and Siluriformes (catfishes). The Characiformes constitute more than 30% of the total fish yield in the Amazon basin, whereas the catfishes are of minor importante. Stable isotope data  indicate that Characiformes species receive most of their carbon throught food chains originating with phytoplankton, while the Siluriformes receive a significant part of their energy from other plant sources.  acatfish  afish  aPeixe  aProteína  aAmazon basin  aBacia Amazonica  aCharaciforme  aEnergy sources  aFonte de energia  aProtein  aSiluriforme1 aFORSBERG, B.
