The effect of body size, activity, feeding and declining PO2 on the rate of oxygen consumption were investigated. Vigorous swimming activity led to a 2.4-fold increase in the rate of oxygen consumption. Feeding did not cause an increase in oxygen consumption. Neither activity nor feeding significantly affected the slope of the line relating log body weight to log oxygen consumption. Oxygen consumption in declining ambient oxygen tension was studied. Use of the oxygen dependence index K1 /K2 suggests that C. delicatula is not a good oxyregulator. The relationship between oxygen dependence index and body size is given by the exponential equation K1K2 = 115.78Q20,769 where QO2 is the weight-specific oxygen consumption (ml O12 /g/h).
