Resumo: Individuals of Bryconamericus iheringii (Boulenger, 1887), collected in the streams of Cambé, Taquari, Água da Floresta and Baroré, which belong to the Tibagi river basin (Parana Sate, Brazil), were analyzed for the purpose of diet study. The collection procedures were standardized in every stream. The stomach contents of the individuals were analyzed qualitative and quantitatively. The food items consumed by the species varied in number, and the main food item consumed differed in each stream. Thus, it was found: vegetable remains and debris, in Cambé; debris, in Taquari; filamentous algae and vegetable remains, in the Água da Floresta; and debris and remains of insects, in Baroré stream. The behavior shift from generalist to specialist strategy as well as the use of detritus as the main food, which can only be found in the river bottom, can indicate that stretches of streams with slower and deeper waters are not preferred by B. iheringii, as neither they are for some groups of aquatic insects which are used as food resource by this fish species

As coletas foram padronizadas em todos os riachos. Os conteúdos estomacais foram analisados qualitativa e quantitativamente. Verificou-se que a dieta de B. iheringii nos quatro riachos consistiu de itens alimentares que variaram em número, e os de maior importância foram: restos vegetais e detrito, no Cambé; detrito, no Taquari; algas filamentosas e restos vegetais, no Água da Floresta; detrito e restos de insetos, no Baroré. O comportamento de mudar de estratégia, de generalista para especialista, e de utilizar o item detrito, que é capturado apenas no fundo, como principal alimento, podem ser indicadores que trechos de riachos com águas mais lentas e profundas não são preferenciais para B. iheringii, como também não são para alguns grupos de insetos aquáticos que servem como seu alimentoUniversidade Estadual De Maringá2008-03-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/106010.4025/actascibiolsci.v28i1.1060Acta Scientiarum.
