Abstract
Food offer and consumption by the fish fauna were studied at medium and high waterlevels in
a macrophyte dominated and strongly hypoxic floodplain lake of the middle Amazon. Detritus was
shown to be the main food item, followed by terrestrial invertebrates and periphyton. Low aquatic
macrophyte consumption is related to its low nutrient value in comparison with other abundant foods
and its seasonal availability.
