Resumo: Studies 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 of Rhinodoras 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. dorbignyi is an insectivorous species and autochthonous items play an important role in the diet of this species.

Para a caracterização da dieta de Rhinodoras dorbignyi, foram realizadas seis coletas bimestrais no alto rio Paranapanema, SP, durante o período de abril de 2010 a fevereiro de 2011. Dos 63 indivíduos capturados, 30 apresentaram algum conteúdo no estômago, sendo utilizados neste estudo. A dieta desta espécie foi determinada utilizando de dois métodos: (i) Índice Alimentar (%IAi); (ii) e a interpretação gráfica da estratégia alimentar. A partir dos resultados obtidos é possível inferir que R. dorbignyi é uma espécie insetívora, sendo que itens de origem autóctone apresentam grande contribuição em sua dieta.Universidade Federal de Santa Catarina2016-02-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2016v29n1p6710.5007/2175-7925.2016v29n1p67Biotemas; v. 29 n. 1 (2016); 67-732175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2016v29n1p67/31232Copyright (c) 2016 Felipe Pontieri de Lima, André Batista Nobile, Diogo Freitas Souza, Edmir Daniel Carvalho, Ana Paula Vidotto-Magnoniinfo:eu-repo/semantics/openAccessLima, Felipe Pontieri deNobile, André BatistaSouza, Diogo FreitasCarvalho, Edmir DanielVidotto-Magnoni, Ana Paula2017-10-18T19:01:55Zoai:periodicos.ufsc.br:article/37860Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2017-10-18T19:01:55Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
