چکیده انگلیسی
It was analyzed antioxidant competence and lipid peroxidation in juveniles of Peckoltia oligospila submitted to transport in plastic bags under different concentrations of dissolved oxygen for up to 24Â h. Oxidative balance of fish transported for 3, 6, 12, and 24Â h in normoxic (NX), moderate hyperoxia (MH), and severe hyperoxia (SH) was evaluated. For this, it was determined the total antioxidant capacity against peroxyl radicals (ACAP) and lipid peroxidation levels (TBARS) in liver, gills, muscle, and brain. After 24Â h and, regardless of water quality, dissolved oxygen concentrations, and duration of transport, no mortality occurred for any of the treatments. The antioxidant competence of P. oligospila in the different organs remained high, except for some occasional decrements. Because of this, TBARS concentration remained low in the different organs, irrespective of transport time or initial oxygen concentrations. According to the results, P. oligospila antioxidant system was efficient enough for the prevention and/or suppression of products derived from lipid peroxidation. Therefore, the oxidative status was not severely affected in the assessed organs over transport time in hyperoxic conditions. Furthermore, Peckoltia oligospila can be safely transported in plastic bags without an extra supply of oxygen for up to 24Â h, since survival was not affected.
