Introduction: The dynamics of marine ecosystems in the context of climatic change are of considerable practical and scientific concern. The practical concern stems from the need to manage the global ocean or at least large parts of it. The study of ecosystem dynamics helps to identify those parameters that drive long-term variability of biological productivity and hence provide a starting point for long-term forecasts for the optimal management of fisheries. Ecosystem dynamics also provides insights into the way in which systems in the sea are affected by pollution and reveals where regulation is needed. As anthropogenic inputs into the sea increase, their impact upon the fish stocks will become more obvious and the need for interaction between fisheries and pollution management will become more urgent. The stakes are raised by the climatic change now facing us.
