Summary
The Bay of Vilaine is a sheltered and shallow ecosystem in Southern Brittany in north-west France. Eutrophication due to high nutrient inputs of the river Vilaine has been evident since the 1980s. In the summer of 1982, hypoxia killed dozens of tons of fish in the bay.
The Bay of Vilaine hypoxia is periodic and mainly caused by phytoplanktonic biomass degradation.
