Mussel farming as a nutrient reduction measure in the Baltic Sea: Consideration of nutrient biogeochemical cycles

► Mitigation of coastal eutrophication is needed. ► Harvest of farmed mussels has been suggested as a measure. ► An effective nutrient reduction measure must consider all biogeochemical processes. ► Anoxic conditions below mussel farms increase sediment release of nutrients. ► Mussel farming as a measure to remove nutrients is therefore questioned.
