SUMMARY:

Fish consumption has gradually increased in recent years, reflecting population growth and the current greater demand for healthier foods, since fish provides a menu with high nutritional value. In view of this scenario, there has been an evolution in the development of technologies that aim to optimize and increase fish production on a large scale, enabling the cultivation of different aquatic species in different systems around the world. The triploidization technique applied to fish diverts energy in the development of the species, if the species is sterile. The objective of this study was to induce triploidization in the Amazonian lambari, using the thermal shock technique. Different temperatures (0°C and 40°C) were tested, with the aim of developing the most viable protocol. The hatching and survival rates of the individuals were evaluated, as well as their zootechnical performance and gametogenesis. For this purpose, the parental specimens were artificially reproduced by hormonal induction, and the triploidization protocol was applied to the zygotes, immediately after fertilization. It is expected to obtain triploid and infertile individuals with greater somatic growth than individuals in the control treatment.
