The objective of this work was to evaluate the effects of different water salinities on tilapia larviculture. Larvae with five days post-hatching were stocked in tanks of 6 L each during 30 days. Treatments were carried out in freshwater and water at 2, 4, and 6 g L-1 salinity, with six replicates. Larvae kept at 6 g L-1 salinity showed total mortality before the ten days of active feeding. Survival and growth at 4 g L-1 salinity were lower than the ones registered for animals kept in freshwater and 2 g L-1 salinity, with similar results to one another.
