The experiment lasted 21 days for each of the evaluated foods, seven days for acclimatization of the animals and the rest for the collection of feces. The research was divided into four experiments: a) six diets were developed containing the inclusion of FA (6%, 12%, 18%, 24%, 30%); and b) six diets containing the inclusion of QA (6%, 12%, 18%, 24%, 30%); six diets containing FM inclusion (6%, 12%, 18%, 24%, 30%) and six diets containing GM inclusion (6%, 12%, 18%, 24%, 30%) in addition to a diet reference. 480 specimens of tilapia with an average weight of 510 ± 12.2 g were distributed in 24 tanks with a capacity of 500L of water adapted for the collection of feces, in a completely randomized design composed of six treatments (per food) and four replications. For the CDAPB of the FA, a higher mean (P 0.05) of CDAPB, being 79.57% and 91.98% respectively. The inclusion level of 6% for FM and GM showed a higher average (P 0,05) de CDAPB, sendo 79,57% e 91,98% respectivamente. O nível de inclusão de 6% para FM e GM apresentou média superior (P
