%X Oxygen uptake (VO 2 ) through the gills in relation to body weight has been studied in Notopterus notopterus at 24.0±1.0ºC under continuous water flow system. With gradual increase in body weight from 5.10 to 122.33 g, the oxygen uptake increased from 1.164-3.975 mlO 2 .h –1 . The log-log plot between the oxygen uptake per unit time and body weight gave a straight line with the slope ‘b’ value of 0.421. The relationship between the two variables was found to be highly significant (r= 0.986; p<0.001). However, the weight specific oxygen uptake decreased from 228.36 to 32.49 with increase in body weight from 5.10 to 122.33 g. A straight line with slope ‘b’ value of   -0.629 was obtained when plotted on log-log coordinates, showing a highly significant negative correlation (r= 0.985; p<0.001). DOI: 10.3126/on.v8i1.4320
