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.
Thank you to all the members, friends and supporters of the SUBMARINER Network who came to Berlin this week and made a success of the 2nd SUBMARINER Conference Better off Blue.
The conference will take place in Berlin, Germany on 27–28 September 2017. It will unite actors from the public, private and research domain working towards a blue bioeconomy throughout the Baltic Sea Region to showcase advances, to create synergies and stimulate active cooperation between the multitude of ongoing projects and initiatives in the region.
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.
Register now for the second SUBMARINER conference "Better off Blue" taking place in Berlin, Germany on 27–28 September 2017! The conference aims to unite actors from the public, private and research domain working towards a blue bioeconomy throughout the Baltic Sea Region to showcase advances, to create synergies and stimulate active cooperation between the multitude of ongoing projects and initiatives in the region.
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.
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.
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.
Watch the launch of the mussel farm in Byxelkrok in the Swedish Kalmarsound in June 2016! The farm is one of six mussel farms that form the basis of the Baltic Blue Growth project. Placed at the northern inlet of the Swedish Kalmarsund, it uses a submerged net-farm production system designed to withstand ice and offshore conditions.
Interreg Baltic Sea Region published an article on legal requirements for mussel farming. In the article, Baltic Blue Growth partner Roland Lemcke from the Ministry of Energy, Agriculture, Environment and Rural Areas of Schleswig-Holstein (MELUR) explains: “Establishing a new mussel farm requires a lot of different or combined licenses, of course with national features, but substantially based on a common European legal framework. Depending on the relevant national system, three, four or more different authorities are involved in such licensing processes.”
