| Abstract: | Physiological responses of mussels Mytilus edulis were determined following 8 months' exposure to two oil concentrations (28 and 125 μg litre−1 total hydrocarbons) and during the process of recovery. There was a significant inverse relationship between the performance of Mytilus edulis, measured in terms of scope for growth, and the concentration of aromatic hydrocarbons accumulated in the body tissues. The marked reduction in scope for growth of oil exposed mussels was primarily due to a reduction in feeding rate and food absorption efficiency. Recovery of physiological responses was coupled to the depuration of aromatic hydrocarbons from the body tissues. Mussels exposed to high-oil concentrations were found to recover more rapidly than those exposed to low-oil concentrations, both in terms of depuration and scope for growth, and there was evidence of ‘catch-up’ growth. Recovery of mussels from both oil conditions was complete after approximately 55 days. |
