With an average body weight of 155 g, oxygen consumption rate was 510.6 and 266.7 mg/kg/h and 120 mg/kg/mL, respectively in three oxygen concentrations. In another group of fishes with an average body weight of 190 g the uptake of oxygen was 492.0 ppm, 263 and 78.88 mg/kg/h, respectively. With an average body weight of 172 g of juveniles, mean rate of oxygen consumption in a DO range of 7.6-4.4 ppm was measured 388.12 mg/kg/h.} }
