Baltic Blue Growth

Initiating full scale mussel farming
in the Baltic Sea

Baltic Blue Growth establishes fully operational mussel farms to counteract
eutrophication and create new blue growth opportunities.

    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.

    Video: Installing the submerged mussel farm off the Kurzeme coast

    Watch this underwater footage of how the fundaments and ropes for the submerged Baltic Blue Growth mussel farm are installed. Placed in the open waters outside the Kurzeme coast in Latvia, the farm will have to withstand rapid water circulation and rough weather conditions. Therefore, the farm is submerged to a depth of about five metres.

    BBG partners come together for 3rd partner meeting in Korsør, Denmark

    As harvesting time is approaching for some of the six mussel farms participating in the Baltic Blue Growth Project, the partners came together to discuss progress and challenges in Korsør. Around 40 participants took part in the two-day meeting, during which the main talking points were the post-harvest process and how to create an economically sustainable business.

  • Eider duck predation affected mussel growth at Musholm Bay

    Eider duck predation affected mussel growth at Musholm Bay

    Baltic Blue Growth partners Orbicon and Musholm have published a summary report on the mussel growth in the Baltic Blue Growth project farm in the Danish Musholm Bay during 2016. “Predation by Eider ducks has considerably affected the mussel production at Musholm last year”, says Maren Lyngsgaard, biologist with Orbicon. The total estimated biomass at the Musholm site was only 0.2 – 3.7 tonnes per production unit, whereas up to 20–25 tonnes of mussels per production unit have been recorded at other Danish mussel farms using similar production systems.

    First Baltic Blue Growth mussel farming stakeholder workshops coming up

    Baltic Blue Growth has set up six demonstration mussel farms at different shores of the Baltic Sea to study the preconditions for commercial mussel cultivation at different sites and with different techniques. In each region with a project mussel farm, Baltic Blue Growth partners have now set up regional stakeholder groups, which will meet regularly over the coming years to accompany the mussel farming activities at the given location, discuss advances, challenges and perspectives for its further development.
