Abstract : Oxygen uptake through the gills of a hill-stream fish Glyptothorax telchitta has been studied in relation to different body weights. The oxygen uptake was determined at 24.0±1°C using a cylindrical glass re spirometer with continuous water flow system. The aquatic oxygen uptake through the gills increased from 1.048 to 8.115 ml oxygen/kg/ hr within the body weight range of 3.215 to 31.355 g. A fish of 17.052 g average body weight consumes 4.461 ml oxygen while the weight specific oxygen uptake was found to be 267.915 ml O2/ kg/hr.
