The lipid values ranged from 6.7 to 7.1%, which are in agreement with values required by this species (6 to 7.5%). According to González-Félix et al. (2002), these values are considered ideal to avoid a decrease in growth and increase in mortality rate of shrimps; in relation to the ash values, diets showed values similar to those found in commercial diets, with maximum of 13%, observed by Melo (2003), when commercial diets for shrimps were analyzed.
