Abstract The present study investigated the impact of stocking density and dietary carbon sources on the growth, oxidative status and stress markers of Nile tilapia (Oreochromis niloticus) reared under biofloc conditions. Six groups were established at three levels of stocking densities [20, 40 and 60 fish (50.47 ± 0.05 g) per m3] and fed the basal diet without carbon sources or with broken rice flour (BRF) or broken wheat grain flour (BWGF) in biofloc units. Water quality [pH, biological oxygen demand (BOD), Total ammonia-nitrogen (TAN), and nitrite-nitrogen (NO2)] values were increased significantly (P
