Resumo: In this study we analyzed the diet and trophic morphology of two species, one of Cheirodontinae and one of Aphyocharacinae, associated with aquatic macrophytes in nine isolated lagoons of the Paraná river floodplain, Brazil, during 2001. Diet showed that Aphyocharax anisitsi feed mainly on microcrustaceans and Serrapinnus notomelas feed mainly on algae. Trophic morphology, including mouth, tooth, gill rakers and stomach showed apparently the same pattern for the two species. However, teeth are the biggest and the hardest in S. notomelas. Regarding intestine length there was significant interaction between standard length (F2.215 = 74.89; p

A análise da dieta mostrou que Aphyocharax anisitsi consumiu predominantemente microcrustáceos e Serrapinnus notomelas predominantemente algas. A morfologia do trato alimentar, incluindo boca, dentes, rastros branquiais e estômago, apresentou, aparentemente, o mesmo padrão para as duas espécies. Entretanto, os dentes são mais robustos em S. notomelas. Houve interação significativa entre o comprimento padrão (F2,215 = 74,89; pUniversidade Estadual De Maringá2006-11-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/16710.4025/actascibiolsci.v28i4.167Acta Scientiarum.
