“…Silva et al ( 2020) also observed higher values of SS and TSS with higher feeding rates, having reportedmaximum values of 225 mL L -1 and 1,450 mg L -1 of solids throughout the rearing of tilapia juveniles when fed with 100% of the satiety. Tilapia nursery studies in a biofloc system demonstrated a wide variation in the values of SS (0.5 to 65 mL L -1 ) and TSS (200 to 1,600 mg L -1 ) (Martins et al, 2017, Lima et al, 2018, Martins et al, 2019, Correa et al, 2020, Durigon et al, 2020, Hisano et al, 2020, Vicente et al, 2020. In this study, the solids were managed to maintain mean values close to 30 mL L -1 and 600 mg L -1 .…”
