  <dc:description>&lt;p&gt;&lt;span&gt;During the 1988 rainy season, I studied the 24 h feeding chronology of juvenile (40&amp;ndash;68 mm standard length) piranhas,&amp;nbsp;&lt;/span&gt;&lt;i class="EmphasisTypeItalic "&gt;Pygocentrus notatus&lt;/i&gt;&lt;span&gt;&amp;nbsp;(Characidae: Serrasalminae) from a natural population inhabiting a small savanna stream in Apure State, Venezuela. Stomach contents analyses, supported by laboratory determinations of digestion rate, showed that these fish are primarily diurnal carnivores. Predatory activity on 4&amp;ndash;5 August 1988 increased markedly after sunrise, peaked around 1100 h, and essentially stopped after sunset. Means of stomach content weight-to-fish weight ratios among the periods sampled were significantly different. Small fish were the major prey at all hours (81% of total prey volume). Underlying factors responsible for the observed 24 h feeding patterns were not investigated, but avoidance of predation by adult piranhas, which were very active near sunset, may have been important.&lt;/span&gt;&lt;/p&gt;</dc:description>
