Tilapia larviculture in freshwater and in slightly saline water

Abstract

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.
