Resumo: The aim of this article was evaluate de relationship among feeding index and reproductive cycle in male red-piau (Leporinus copelandii), in the low basin of paraiba do sul river. Fishes were collected monthly, from February 1998 to march 1999, and obtained the following param-eters: total condition factor (k1) and somatic (k2), stomach repletion index (SRI) and stomach repletion stage (SRS), and gonadal maturation. in general, condition and gonadal parameters showed an inverse relation with nutritional parameters. during the spawning season (september to January), was observed low values of SRS and SRI, fol-lowing an increase of these parameters after spawning, and it seems to be a natural mechanism of corporal condition recovering. Key-Words: Leporinus, fish, reproduction, reproductive biology.
