Resumo: | The study evaluated the effect of oral administration of sulfated polysaccharides (SP) extracted from the marine macroalga Kappaphycus alvarezii on survival and weight gain of Nile tilapia post larvae during sex reversal in a stress situation. SP were extracted from the seaweed by enzymatic digestion and incorporated into the diet before the addition of the hormone 17-α-methyltestosterone, and administered at the doses of 0.05, 0.1 and 0.2 mg g-1 of body weight and a control (without SP), for 28 days. In the last week of sex reversal a stress situation was established by removing the aeration and water renewal. Survival and weight gains data were subjected to a variance analysis (ANOVA) and Tukey's test for averages differentiation at significance levels of 1 and 5%. Weight gains were greater in animals that received SP, regardless of the used dose and better survivals were obtained when SP were administered at the doses of 0.05 and 0.1 mg g-1, with values of 79.90 ± 5.68 and 77.60 ± 1.80%, respectively. The study revealed that small doses of the SP were able to improve survival, daily weight gain and final average weight of tilapias submitted to a stress situation. |

Os PS foram extraídos por digestão enzimática e incorporados à ração antes da adição do hormônio 17-α-metiltestosterona, sendo administrados nas doses de 0,05; 0,1 e 0,2 mg g-1 de peso vivo e um controle (sem PS), durante 28 dias. Na última semana da reversão sexual foi estabelecida uma situação de estresse, pela supressão da aeração e renovações de água. Os dados de sobrevivência e ganhos de peso foram submetidos à análise de variância (Anova) e teste de Tukey para diferenciação das médias, aos níveis de significância de 1 e 5%. Os ganhos de peso foram maiores nos animais que receberam os PS, independente da dose utilizada e as melhores sobrevivências obtidas quando os PS foram administrados nas doses de 0,05 e 0,1 mg g-1, com valores de 79,90 ± 5,68 e 77,60 ± 1,80%, respectivamente. O estudo revelou que pequenas doses dos PS, foram capazes de melhorar a sobrevivência, o ganho de peso diário e o peso médio final das tilápias submetidas a situações de estresse.
