Rapid development of aquaculture units in the coastal waters surrounding the islands and islets additionally contributes to marine pollution. Elevated levels of nutrients and heavy metals have been found, associated with fish farm operation in the Gulf of Astakos.

beds and other seabed communities. Furthermore. overfishing and illegal fishing practices employed by professional and amateur fishermen threaten the quality of the marine environment. It is expected that this ecosystem will be affected in the future by the ongoing works for the diversion of river Acheloos upstream causing changes in the region of Mesolongi. This will in turn affect sedimentation rates, the annual freshwater volume flowing into the delta and hence productivity in the greater area.
