Resumo: The present experiment was carried out in order to evaluate the productive performance of Nile tilapia (Oreochromis niloticus) fingerling reverted for male. The fingerling was maintained under different stock densities, in intensive system type “raceway"; during the winter period. A complete randomized expeimental design was used with three stock densities, 7, 14 and 21 fish / m³, and with two repetitions for treatment. The 252 fingerling selected for homogeneous weight were distributed in six concrete tanks in which the water was renewed every hour. Feeding rate was accomplished twice a day ad libitum. In the first two months crumbly ration was supplied with 40% of crude protein and in the third month it was replaced by extruded ration with 35% of CP. The averages of water temperature in the periods of the morning and afternoon were, respectively, of 19.6 and 22.6°C, considered low for the good development of this species. KEY-WORDS: Nile tilapia; intensive system, stock densities.

O presente trabalho foi realizado para avaliar o desempenho produtivo de alevinos de tilápia-do-Nilo (Oreochromis niloticus), revertidos para macho, mantidos sob diferentes densidades de estocagem, em sistema intensivo de criação tipo raceway, durante o período de inverno. Em delineamento inteiramente casualizado avaliaram-se três densidades de estocagem, (7, 14 e 21 peixes /m³), com duas repetições por tratamento e com duração de 125 dias. Foram selecionados 252 alevinos com peso homogêneo, distribuídos em seis tanques de alvenaria, com renovação total da água de uma em uma hora, com arraçoamento realizado duas vezes ao dia ad 1ibitum. Nos dois primeiros meses, os alevinos foram alimentados com uma ração farelada contendo 40% de proteína bruta que, a partir do terceiro mês, gradativamente, foi substituída por uma outra, extrusada contendo 35% de PB. As médias de temperatura da água nos períodos da manhã e da tarde foram de 19,6 e 22,6°C, respectivamente, consideradas baixas para o bom desenvolvimento desta espécie.
