The present study deals with aspects of sexing, breeding, nursery and growth of pirarucu, Arapaima gigas, presented in four chapters. The first chapter revealed historical aspects of introduction and reintroduction of pirarucu. Now, the reintroduction of pirarucu in the past decade had another purpose, which was the development of studies in research management, growth and reproduction. In the second chapter we have developed different technologies for pirarucu sex identification: ultrasound, which generated different images for male and female gonads; laparoscopy that generated clear images of the gonads, and can distinguish gonadal stages. Was a tested variation in levels of estradiol and testosterone hormones in fingerling and juvenile, ...
