M. M.  aConsumption of zooplanktonic organism by Astyanax faciatus Curvier, 1819 (Osteichthyes, Characidae) in Lobo (Broa) reservoir, Sao Carlos, SP, Brazil.  c1984  aThe consumption of zooplanktonic organisms by young and adult fish of Astyanax fasciatus in Lobo Reservoir was studied from October 1978 to September 1979 by analysisng the abundance of zooplankton in the gut of fishes and relating it to the variation of the zooplankton community in the lake. To analyse the diet the following methos were used: numeric frequency of occurrence and frequency rate. Astyanax fasciatus showed a large spectrum of feeding. The young stage feeds mainly on zooplankton and macroinvertebrates (insect larvae) but the adults also consume algae and detritus. Even in relation to the zooplankton the young stage showed a food preference different from that of the adults, selecting copepods over cladocerans, while the adults consumed more cladocerans.  afish  apredation  azooplankton  aPeixe  aPredacao1 aMATSUMURA-TUNDISI, T.  tHydrobiologiagv.113, p.171-184, 1984.
