  • Bioremediation with aquatic biomass

    Bioremediation with aquatic biomass

    The SUBMARINER Network has identified mussel and macroalgae cultivation and harvest as possible routes to realising two of its visions for 2030: marine resources as a part of the Baltic Sea Region sustainable energy and biomass portfolio and maintaining the Baltic Sea Region’s natural capital. Mussel and algae cultivation not only alleviate eutrophication in the Baltic Sea by taking up nutrients, they are also excellent substitutes for human food and animal feed. Around the Baltic Sea, innovative projects are being implemented, where aquatic biomass play an important role in remediating eutrophication – both off and on land.

  • Mussel farming to the rescue - mitigating eutrophication in the Baltic Sea

    Mussel farming to the rescue - mitigating eutrophication in the Baltic Sea

    Farming of blue mussels is a new, exciting solution to an old problem – eutrophication of the Baltic Sea. Mussels filtrate, extract nutrients and improve water quality, which may reduce the frequency of algal blooms. Consequently, mussel farming is being tested as an environmentally responsible tool to reduce Baltic Sea eutrophication. The farmed mussels could potentially be used as a replacement for fish meal or soya meal to feed poultry or farmed fish as well as for bioenergy production. As a response to a new study that suggest that mussels emit substantial quantities of methane, two scientists from the BBG project decided to set the record straight.
