The aerial Qo2 is not significantly changed after several months laboratory storage in tap water (Table II). Variability in Qo2 was high, ranging from 18 to 150. Oxygen consumption in water is significantly higher than aerial respiration (Table III). The Qo2 from mussels stored in tap water several months was sig- nificantly (36%) less than recently collected animals, however, the difference in weight tends to minimize the reduction. Aquatic respiration exceeds aerial Qo2 even after prolonged storage in tap water. Part of the elevated Qo2 in water is due to activity; siphoning water, valve and foot movement. There was no change in O().. when the stored animals were pretreated 24 hr with penicillin (800 u/ml) in the"water : Qo, 160 ±37 (5). The weight specific aquatic Qo2 is a logarithmic function of dry tissue weight (Fig. 2). The slope of the regression line is significantly different from that noted for aerial respiration (P < ).
