A total of 120 fish (47.8 ± 7.7 g and 15.2 ± 0.7 cm) were randomly distributed in 12 tanks of 600 L (10 fish per tank) and fed commercial diets (28% protein and 5% lipids) supplemented with different levels of essential oil (0, 0.5, 1.0, and 1.5%), with three repetitions three times a day for 30 days. After 30 days, growth, hematological parameters, and fillet composition were evaluated. Disease resistance was tested by intraperitoneal injection of Aeromonas hydrophila (1.1 × 1012 CFU/mL) in five fish per tank, and mortality and hematological parameters were evaluated after 10 days. The results showed that the growth and hematological parameters of fish supplemented with 0.5 and 1.0% essential oil did not differ from the control group, but with 1.5% supplementation weight parameters, condition factor (1.27) and the mean corpuscular volume (188.9 fL) decreased, while glucose levels (114.8 mg dL−1) increased. In the fillet composition, there was only an effect on protein, which increased (19.8–19.9%) in fish fed the diets supplemented with essential oil. The bacterial infection did not affect survival, in hematological parameters, only glucose (87.4 mg dL−1) decreased in fish supplemented with 1.5% essential oil. It can be concluded that supplementation with the essential oil of M. mollis can increase the protein content in the fillets of B. amazonicus juveniles.  aBlood chemistry  aImmunostimulants  aAditivos dietéticos  aCaracterísticas do filé  aDietary additives  aFillet characteristics  aImunoestimulantes  aQuímica do sangue1 aBENITES, Z.
