The knowledge about organogenesis of fish larvae is a useful tool to establish their functional capabilities and systemic physiological needs in order to ensure welfare and optimal growth under aquaculture conditions. Feed in hatchery affects digestive functions inducing faster or slower development. Thus, this study aimed to evaluate growth and morphophysiological development of the gastrointestinal tract in pacu Piaractus mesopotamicus larvae, rearing under live food and formulated diet with different weaning protocols, through the analysis of production performance, histology, histochemistry and enzymology (trypsin, amylase, lipase, leucine-aminopeptidase, maltase and acid proteases). Therefore, this research contributes to the better understanding of the development of the gastrointestinal tract in pacu larvae and its digestive capacity
