【 摘 要 】

http://dx.doi.org/10.5007/2175-7925.2016v29n1p67Studies describing the diet of fish are important to determine trophic chain relationships, habitat occupation, trophic niches, and to define food habits of species. To describe the diet ofRhinodoras dorbignyi , six collections were made bimonthly in the upper Paranapanema River, SP, from April 2010 to February 2011. Of the 63 samples collected, 30 had stomach content. The diet of this species was determined using two methods: (i) alimentary index (AI%) and (ii) graphical analysis of feeding strategy. Based on the results,R. dorbignyiis an insectivorous species and autochthonous items play an important role in the diet of this species.
