In order to improve the cost-benefit relationship in aquaculture production systems, several technological advances have been formulated. The biofloc technology system (BFT) offers the advantage of functioning as a water treatment method, allowing the conversion of ammonium to nitrites and nitrates by using the properties of chemo-autotrophic bacteria. Biofloc technology system is considered a relevant cost-effective and ecological method, with potential use in aquaculture (Crab, Defoirdt, Bossier, & Verstraete, 2012). In addition, BFT promotes biosecurity by preventing the proliferation of pathogenic organisms, as well as the generation of bacterial protein flocs that are constantly renewed in the system, favouring the continuous in situ production of a microbial protein source (Avnimelech, 2012). The biofloc is constituted by a suspended heterogeneous mixture of microorganisms containing fungi, algae, microalgae, bacteria (autotrophic, chemo-autotrophic, photo-autotrophic, filamentous, heterotrophic), and flagellates and ciliates among other protozoa. The biofloc system also comprises organic matter in the form of colloids, organic polymers, alkaline earth metals, undigested food, organic waste, dead
