Danish stakeholder workshop on mussel mitigation cultures in Skive Fjord

The mussel mitigation concept of removing nutrients was introduced to various stakeholders from politics, business, property owners and several organizations of recreational activities at the Danish workshop on the 5th of September 2018. Mussel farming, the concept of mussel mitigation farming, legislation issues and the potential and perspectives of mussel mitigation cultures were presented and lively debated.

During the groupwork and the following presentations the workshop participants were invited to share their knowledge, concerns and suggestions regarding mussel mitigation farming in Skive Fjord. A general consensus was the need for identifying different areas of interests to stakeholders to avoid conflicting uses of the sea and shoreline.

The workshop was organized by DTU Aqua in co-operation with the Department of Environmental Science at University of Århus.

Test of socio-economic survey at the German case study

On May 31st 2018, the EUCC-D project team travelled to Alt Reddevitz, a small village located in the eastern part of Rügen Island, Germany. This coastal area is a popular summerhouse destination surrounding the Greifswald Bay, where the project mussel farm was installed in April 2017.

The purpose of this trip was to test the survey about public perception and social acceptance of the mussel farm. The actual survey will be carried out between July and September 2018 and will be directed at tourists, inhabitants and holiday house owners within the case study area Hagenschen Wiek

OPTIMUS project members met this April in Warnemünde, Germany for a series of presentations and discussions on progress over the past year, as well as planning and organization for activities in 2018-2019. WP leaders presented initial findings to project partners and formalized coordinated actions for the coming mussel settlement and growth season. OPTIMUS as an integrated project, and individual WPs were described to the independent advisory board, with a discussion panel. All participants were provided an excursion to the test farm site in Greifswald Bay. Project members are grateful to the Leibniz-Institute for Baltic Sea Research for hosting this year's annual meeting and look forward to reconvening at IOPAN in 2019.

First German stakeholder workshop -

Lively debate about mussel farming during first German stakeholder meeting


The idea behind mussel farming for nutrient removal was introduced to various stakeholders from politics, tourism, business, science and environmental protection during our first German workshop on the 23rd of January 2018. Site selection processes, installation challenges and first growth results in the Greifswald Bay were presented and lively debated.

Workshop participants were invited to share their knowledge and to “flag” potential further locations for internal nutrient reduction measures in German coastal waters: Blue flags for mussel farms, green for floating plant islands, yellow for mechanical measures such as sediment dredging, red for chemical measures such as phosphorus precipitation with aluminum and white flags at locations where no internal measures should take place. In one point, all participants agreed: Chemical measures in coastal zones have no acceptance so far.

The workshop was organized by the Coastal Union Germany in co-operation with the Leibniz Institute for Baltic Sea Research Warnemünde and the South Baltic project LiveLagoons.
