Each day, 20 larvae from each tank were analyzed at the macro and microscopic level to assess larval quality. We observed the fol- lowing parameters: swimming activity, lipid reserves and color of the hepatopancreas, intestinal contents, deformities, presence of epibionts, adhered particles, necrosis and muscular opacity (FAO, 2003; Suita et al., 2015). Performance parameters used to evalu- ate treatments included ultimate survival (%), final dry weight (mg,
