Abstract: | - 1.1. The relationships of oxygen consumption (Vo2, ml/min/fish), ventilation volume (Vg, ml/min/fish), stroke volume (Vs, ml/stroke/fish), respiration frequency (RF, stroke/min) and oxygen utilization (U, %) to body weight (W, g) in the tilapia under resting and normoxic conditions were Vo2 = 0.002835W0.754193, Vg = 0.688965W0.722786, Vs = 0.002790W1.017188, RF = 248.58210W−0.296139, U = 0.000935W + 87.394288, respectively.
