The adaptation characteristics of the White Sea blue mussels Mytilus edulis L. were investigated under the effect of oil products. The physiological condition was estimated by the heart activity, and the biochemical status – by the lipid composition. The heart rate was registered by a non=invasive technique. An increase in HR was observed at oil concentrations of 8.0 and 38.0 mg/l. In treatments with low concentrations (0.4 & 1.9 mg/l) a reliable decrease in the mussel HR occurred on the 4th day of the experiment. Strong fluctuations of the cardiac activity were noted under all concentrations. After 6 days of oil treatment, organs of the mussels (distal and saggital parts of the mantle, foot) were sampled to determine total lipid composition. Low concentrations of oil products caused no significant changes in the lipid composition. Under high concentrations the content of cholesterol and arachidonic acid decreased. This was apparently a specific compensatory response of blue mussels to heavy oil contamination.
