This 30-day trial showed weaning (Artemia sp.) artificial diet after 15 be optimal, with beneficial effects on growth, weight, larva yield. No differences survival rate, size heterogeneity, condition factor observed among groups. Live appropriate time was while only associated severe impairment. Liver pathology not seen any group.
