As one of the most important wetland sites in the Mediterranean region, the Lagoon of Venice is covered by the European Union’s policy for wetlands preservation. Moreover, conservation of the Lagoon is a priority for the local economy. At this time, however, the Lagoon of Venice is environmentally degraded, due to the industrial pollution from chemical plants and refineries in nearby Porto Marghera, and its fish stocks have been depleted by excessive commercial fishing, an important economic activity for the Venice area and the Veneto region. In addition, biodiversity is endangered by an exotic clam species that was artificially introduced for commercial fishing during the 1980s.
