Aclimatação do camarão marinho Litopenaeus vannamei (Boone, 1931) à água doce com diferentes estratégias de alimentação e calagem - DOI: 10.4025/actascianimsci.v28i1.668

Litopenaeus vannamei postlarvae with 9-10 (PL 9-10 ), 25-26 days old (PL 25-26 ) 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, with different 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 from 40.44 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 < 0.05) the zootechnic parameters of the species in a significant way.
