Mortality and ATP content during experimental exposure to air were determined in two groups of Mytilus edulis L., one lying dry during low tide (wild), the other continuously covered by sea water in its habitat (cultured). When kept in sea water continuously, ATP levels were 2.02 ± 0.14 mm in cultured and 2.08 ± 0.09 mm in wild mussels. Mortality was negligible and almost equal for both groups (Fig. 2). In mussels, exposed to air for 7 days, a maximum decrease in ATP content to 1.18 mm (cultured) and 0.94 mm (wild) was determined after 3 days. Mortality in wild mussels reached 9% and stopped after reimmersion in sea water, whereas mortality in cultured animals was 24% at the end of exposure and continued under aerobic conditions, being 50% after 4 days of aerobiosis. In both groups normal ATP levels were restored within 2 to 3 days of aerobiosis (Fig. 2). When mussels were exposed to air and immersed in sea water alternately for periods of 24 h, ATP levels were maintained at about 1.4 mm for cultured and 1.2 mm for wild animals. Mortality was equal in both groups and did not exceed the control values. During subsequent exposure of 5 days, no further decrease in ATP concentration was observed in both groups (Fig. 3).
