P車s-Larvas do camar o Litopenaeus vannamei, na fase de PL9-10 e PL25-26 foram aclimatadas 角 芍gua doce (0,0 ㏑), objetivando promover cultivos em regi es interioranas. Para isso, foram realizados dois experimentos conduzidos em aqu芍rios com capacidade 迆til de 44 litros e densidade de estocagem de 11,36 p車s-larvas/L. No experimento 1, foram testadas diferentes concentra es de cal hidratada (0,018 g a 0,031 g) e 2 dietas, formuladas 角 base de ra o comercial para camar o e biomassa de art那mia. No experimento 2, foram testadas 5dietas com diferentes concentra es de biomassa de art那mia (0% a 100%), inseridas em ra es de peixes e camar es. No final do processo de aclimata o, a sobreviv那ncia das p車slarvas variou de 40,44% a 98,04%. Concluiu-se que p車s-larvas do Litopenaeus vannamei podem ser aclimatadas 角 芍gua doce e que o aumento da concentra o de cal e de art那mia na ra o melhoraram significativamente (p%26lt;0,05) os parametros zoot谷cnicos da esp谷cie. Litopenaeus vannamei postlarvae with 9-10 (PL9-10), 25-26 days old (PL25-26) were acclimated to freshwater (0 ppt) for the purpose of attending the inland cultures. Two experiments were conducted in 44 liter aquariums with stocking density of 11.36 postlarvae/L. In experiment 01, different concentrations of hydrated lime (0.018 g a 0.031 g) and two diets, formulated with commercial shrimp ration and artemia biomass, were tested. In experiment 02, five diets, withdifferent concentrations of artemia biomass (0 to 100%) inserted in fish and shrimp rations, were tested. At the end of the acclimatization process, the postlarvae survival varied from40.44 to 98.04%. Results showed that Litopenaeus vannamei postlarvae can be acclimated to freshwater. Also, the increase of lime concentration and the artemia biomass in the ration improved (p%26lt;0.05) the zootechnic parameters of the species in a significant way.
