The NutriTrade project has now contracted five additional mussel farmers. The mussel farms are located along the Swedish east coast and on Åland. The total contracted harvest amounts to 104 tons, and harvest will be carried out during 2017 and 2018. The mussel harvesting will contribute to the removal of nitrogen and phosphorus from the sea, and thereby help to restore marine water quality. The mussel farmers are compensated for harvesting the mussels, but will retain the ownership. This implies that the mussel can be sold and used for different purposes such as fish or animal feed and fertilization.
