Abstract

The purpose of this study was to describe the processes of reproduction and incubation of the eggs during the first sexual maturation of B. orbignyanus, at EPDA - Volta Grande. Males and females that was born in December 1992 were induced to spawn through hypophysation, with identical treatments. Ovulation of 96% was obtained 4-5 hours after the last dose. A total of 99,000 post-larvae, which were fed with 700,000 post-larvae of "tambaqui" (Colossoma macropomum), were produced during the incubation process.
