Resumo: The study of the feeding of Astyanax bimaculatus was undertaken from March 1996 to February 1997. Collections were made monthly in the influence area of the Corumbá Reservoir, in three environments: Corumbá, Córregos and Rio do Peixe. Gill and drag nets were used for collections. Occurrence and volumetric methods were used to determine diet which was composed of twenty-seven items. Feeding index for total fish analyzed (n = 401) indicated that 62.85% of the diet was composed of vegetal matter and 37.13% of animal matter. Main items were Dicotiledoneae (IAi = 58.70%) among vegetation and insects (IAi = 34.65%) among animals. Seasonal, area and fish size variations influenced diet variation and suggest the opportunistic habit of the species

Foram utilizadas redes de espera e de arrasto. Foram aplicados os métodos de ocorrência e volumétrico e o índice alimentar para analisar a dieta, que foi composta de vinte e sete itens. O índice alimentar, para o total de indivíduos analisados (n=401), indicou que 62,85% da dieta foram compostos de matéria vegetal e 37,13%, de matéria animal. Dentre os vegetais, destacou-se Dicotiledoneae (IAi=58,70%) e dentre os animais, os insetos (IAi=34,65%). Foram constatadas variações na dieta, relacionadas com o tamanho dos indivíduos, sazonalidade e espacialidade, resultados que sugerem ser a espécie oportunista, de hábito alimentar onívoro, com tendência à hervioria-insetivoriaUniversidade Estadual De Maringá2008-05-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/273510.4025/actascibiolsci.v23i0.2735Acta Scientiarum.
