RESUMO
Culture of Litopenaeus vannamei in freshwater (0.0 g L-1) and low alkalinity and hardness (<50 mg L-1 CaCO3) were performed during 2008 to 2009, with the aim of evaluating the influence of adding of lime, to maximize production indices of shrimp. Post-larvae of this species, with 10 to 12 days (PL10-12), were initially acclimated to fresh water and then stored at density of 17 PL m-2, 12 experimental ponds of 60 m2. The concentrations of lime (4.0, 8.0, 12.0 and 16.0 t ha-1 cycle-1) were evaluated in the presence or absence of fertilizer-based K+ and Mg2+, in completely randomized. The diet was formed based pelleted feed, shrimp with 32% protein, and administered at feeders. The monitoring of physical and chemical qualities of water was carried out in different phases. After 60 days of cultivation,the best survival were observed in treatments of 8.0 and 12.0 t ha-1 without fertilizer, and application of 4.0 t ha-1 in crops with fertilizer. It was concluded that the use of lime favors the growth of L. vannamei in freshwater.
