In 1966 and 1970, French oysters were hit by two successive disease outbreaks. To save the oyster farming industry, the government allowed farmers to import oysters of the Crassostrea gigas (C. gigas) species from the northwest Pacific (NW Pacific) area. While these operations were an economic success, they also led to the introduction of non-native species in European waters that may have negatively impacted oysters and other marine species. Since 2008, a new disease outbreak has caused significant declines in the oyster population and the French government is again considering the importation of oyster stocks.

While animal advocates don't support oyster farming, the paper is a useful case study showing how such farming systems can have long-term negative effects on native species in marine ecosystems. The study also shows how government authorities may possess limited knowledge about not just the impacts of such introductions but also when and how often they are actually occurring.
