Resumo: was analyzed. The present study is based on an analysis of the stomach contents of 261 specimens belonging to six species of fish in a 200 m section of the Ceará Mirim river, in Umari (5º 37’ 47” S and 35º 37’ 9” W), in the Taipu district of Rio Grande do Norte state. Monthly collections were performed between february, 2001 and april, 2002, with 4-hour fishing periods using casting nets, hooks, sieves and bottom-dragging nets with 5 mm-thick mesh. The relative importance of the diet items was measured by frequency of occurrence, numerical frequency and Kavakami and Vazzoler’s (1980) food index. The nutritional coefficient was also determined. It was verified that the species consume mainly algae, aquatic plants, insects, crustaceans, mollusks and sediment. In light of the findings, it can be inferred that the food consumed by the species is located in the living environment

Foram realizadas coletas mensais, entre os meses de fevereiro de 2001 a abril de 2002, com o esforço de pesca de quatro horas, sendo utilizados: tarrafa, anzóis, peneiras e rede do tipo picaré, com malha de 5 mm. A importância relativa dos componentes da dieta foi medida pela freqüência de ocorrência, pela freqüência numérica e pelo uso do índice alimentar proposto por Kawakami e Vazzoler (1980). Foi determinado ainda o coeficiente nutricional. Verificou-se que as espécies consomem principalmente: algas, vegetais superiores, peixes, insetos, crustáceos, moluscos e sedimentos. Diante do exposto, pode-se inferir que o hábito trófico das espécies se localiza no corpo de águaEditora da Universidade Estadual de Maringá2008-03-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/122610.4025/actascianimsci.v27i2.1226Acta Scientiarum.
