The rate of metabolism in fishes is measured by determining the oxygen consumption. The present investigation has been carried out to see oxygen uptake through the gills in relation to body weight in Notopterus chitala at 27.5 ± 1.0ºC using continuous water flow system. In Notopterus chitala the oxygen uptake increased from 0.394 to 4.640 mlO2h-1 with gradual increase in body weight from 1.166 to 98.750g. the weight specific oxygen uptake decreased from 345.967 to 46.990 mlO2.Kg-1.h-1. for the same weight range. The log-log plot of oxygen uptake(mlO2h-1) in relation to body weight gave a straight line with the slope (b) value 0.558. The estimated intercept (a) value was found to be 0.446. The relationship between oxygen uptake and body weight was found to be highly significant. However, the weight specific oxygen uptake decreased by a power of -0.444.
