Abstract
Oxygen uptake by one day fasted juveniles of Wallago attu in relation to their body weight was studied in three different concentration of dissolved oxygen, i.e., Saturated (SW), DO 7.6-6.8 ppm, nearly Normoxic (NW) 6.8-4.4 ppm and Hypoxic (HW) 2.5-0.9 ppm at a temperature of 28±1°C in laboratory. 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.
