Effect of water salinity on the oxidative system of juveniles of the North Atlantic white shrimp <scp> <i>Litopenaeus setiferus</i> </scp> reared in biofloc technology

This study evaluated the effect of biofloc technology (BFT) at 3 (lsBFT) and 35 (hsBFT) practice salinity units (psu) on zootechnical performance, oxygen consumption, antioxidant activity, oxidative damage Litopenaeus setiferus juveniles reared in outdoor tanks. After 90 days, no significant differences were observed terms survival (p > .05). The final weight as well wet gain, biomass, feeding conversion ratio (FCR) showed higher values for shrimp with hsBFT than those lsBFT < Compared to that treatment, high consumption (VO2) was treatment under fasting postprandial conditions activity enzymes catalase, superoxide dismutase, glutathione-S-transferase from muscle did not show between treatments Regarding lipid peroxidation (LPO) oxidized protein (PO) samples, LPO, whereas PO significantly .05), which related adaptation L. BFT low is relatively weak because their growth excessive produced.
