The chemical composition of the experimental diets is shown in Table 1, with protein values around 35%. This percentage was considered ideal for the development in the juvenile phase of L. vannamei according to Rivas-Vegas et al. (2006) and Holme et al. (2009). For humidity, values below 13% were observed to be commonly found in commercial diets, and were considered appropriate for the formulation of diets for aquatic animals avoiding excessive drying and decreased protein quality of pellets, according to Cuzon and Guillaume (1997).
