The objective of the present study was to evaluate the ability of bioflocs to assimilate and transfer antioxidant compounds present in açaí <em>Euterpe oleracea </em>to juvenile <em>Penaeus vannamei</em> shrimps grown in a biofloc system. Juvenile shrimp were distributed into four treatments (control, 5, 20, and 80 mg açaí L-1), containing 31 shrimp/tank (90 L), and cultivated for 30 days. Every 24 h throughout the experimental period, the respective açaí concentrations were added directly to the cultivation water. The bioflocs and hepatopancreas lost their antioxidant capacity with increasing concentrations of açaí, however, lipid damage was mitigated after treatment with 20 mg of açaí L-1 (p &lt;0.05). The application of 20 mg açaí L-1 increased the mean values of the height and area of the anterior intestinal microvilli (p &lt; 0.05). Mortality and protein and lipid damage in shrimp muscle increased with daily administration of 80 mg açaí L-1 (p &lt; 0.05). It is concluded that the bioflocs were able to assimilate the antioxidants present in the açaí and transfer them to the shrimp, the administration of 20 mg açaí L-1 presented the best performance demonstrating the possibility of its application in the cultivation of <em>P. vannamei</em> in a biofloc system.
