AB  - Oxygen uptake by one day fasted juveniles of <I>Wallago attu</I> 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&plusmn;1&deg;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.
