The main objective of the larval stage is to obtain nutrients for their ontogenesis; for their understanding morphological studies, associated with enzymatic responses, must be carried out. Given that the larviculture is the bottleneck of production systems in aquaculture is intended to address this revision in order to understand the relationships between the environment and the changes occurring in the transformation of larvae to juveniles, in order to ensure success in the most complex phase in the life of the fish.esCorporación Universitaria LasallistaAcuiculturaAlevinosEnzimasOntogeniaNutrientesArticle
