The aim of this study was to register the diatoms present in the stomach contents of five
individuals of Mylossoma duriventre Cuvier, 1818 colleted in Maicá Lake, Amazonas River,
Santarém, Pará, Brazil. The diatoms community was composed of 42 taxa ranked in 16 genera.
The more representative genera were Gomphonema Ehrenberg, Eunotia Ehrenberg and
Encyonema Kützing. Individual (sample) 2 showed the largest number of taxa and individuals,
followed by individual (sample) 1. The samples of individua1s and 2 were composed by
periphytic diatoms, indicating that these fishes used aquatic macrophytes in their feeding.
Samples of individuals 3, 4 and 5 were predominated by metaphytic and benthic diatoms
suggesting that fishes used fruits, seeds and flowers in their feeding, which were collected close
to the sediment. |
