Resumo: This experiment aimed at comparing growth performance and survival of four Nile tilapia (Oreochromis niloticus) strains called CESP, Pernambuco, Santa Catarina and Thailand in sex reversal phase. Thirty Nile tilapia fries were stocked in 4.5L aquaria (6.66 fries/L) with recirculation system and water temperature control. The fishes were fed with ration containing 60mg/kg of 17 alpha-methyltestosterone, six times a day during 30 days. The experimental design was randomized with four treatments (strains) and seven replications. Total length, weight gain, specific growth rate, survival rate and sexual reversion efficiency were submitted to Anova, means compared by Tukey test and sex reversion by qui-square means. Santa Catarina and Pernambuco strains demonstrated better sex reversion efficiency when compared with CESP and Thailand. Thailand and Santa Catarina strains showed better values of survival, growth performance and specific growth rate than CESP and Pernambuco strains. Thus, Thailand and Santa Catarina strains are more indicated to rear in recirculation system during sex reversal phase.

O objetivo do projeto foi comparar o desempenho e a sobrevivência dessas diferentes linhagens de tilápia do Nilo na fase de reversão sexual. As pós-larvas foram estocadas em aquários de 4,5L em sistema de recirculação e com temperatura constante. Os peixes foram alimentados com ração contendo 60mg/kg de 17 alfa-metiltestosterona, fornecida 6 vezes ao dia, por período de 30 dias. O delineamento foi inteiramente casualizado com 4 tratamentos (linhagens) e 7 repetições. Os parâmetros avaliados foram: comprimento total, ganho de peso, taxa de crescimento específico, taxa de sobrevivência e eficiência de reversão sexual. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey. A análise de reversão foi submetida ao teste de qui-quadrado. O resultado demonstra que houve maior eficiência na taxa de reversão sexual nas linhagens Santa Catarina e Pernambuco quando comparados com a CESP e a Tailandesa. As linhagens Tailandesa e Santa Catarina obtiveram maior taxa de sobrevivência e desempenho satisfatório durante a fase de reversão sexual, portanto, apresentam-se como as mais propícias para a criação em sistema de recirculação na fase de reversão sexual.Editora da Universidade Estadual de Maringá2008-04-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/179410.4025/actascianimsci.v26i3.1794Acta Scientiarum.
