First excursion to floating wetlands

What wonderful and creative ideas come up when you mix people with different research backgrounds! Scientists from the IOW, the University of Rostock, BUND and EUCC-D discussed how floating wetland design could be ameliorated regarding sustainability and durability or which macrophytes would match different installation sites. The workshop took place at the aquaculture research institute in Born and finished with an excursion to the Nationalpark Vorpommersche Boddenlandschaft.


Together with our cooperation partner – the Federal State Institute of Agriculture and Fishery MV – we installed the first two floating islands in the aquaculture research station in Born at the Darss-Zingst Bodden Chain (Germany). The two floating wetlands, made out of stainless steel and reed stems, were planted with a variety of native emergent macrophytes and remove phosphorus and nitrogen from the eutrophicated waters.

The new “Meer & Küste” magazine is now available!

This summer, EUCC-D publishes another issue of the magazine „Meer & Küste“ (Sea & Coast), which is now available along the German Baltic Sea coast.

The current 36 page issue deals with the topic of water quality and the manifold environmental problems that the Baltic Sea and its users are struggling with: from the burden of pharmaceutical residues to plastic waste and non-compliance of EU targets. In terms of ecological water quality, which is not to be confused with the quality of bathing water, the Baltic Sea is not in good condition. Addressing this problem, which has long been known, the authors from science, business and education present innovative approaches to improve water quality, such as mussel farms and floating wetland installations. They can support priority measures to reduce agricultural nutrient inputs and create local effects. Among other topics, further articles inform about the functions of sewage treatment plants, seagrass beds and bogs. Children are also provided for in the magazine: Within the section „Lup fragt, Experten antworten“ (Lup asks, experts answer), they can learn about the influence that urine has on the Baltic Sea and on the painting and puzzle page, they can discover the miracle of mussels.


The magazine “Sea & Coast” is aimed at tourists, local residents and people interested in the coast, but it also appeals to experts from universities, authorities and associations. It is now available, free of charge, from numerous tourist information offices, youth hostels, (environmental) educational institutions, scientific institutions and authorities in Northern Germany. The current issue is also available online as a PDF.

The publication of this year’s magazine is mainly funded by the projects BONUS OPTIMUS, LiveLagoons and Morpheus.

Flowering and first “visitors” on our floating wetlands

We have a frequent visitor on our island 🙂 Every morning the gray heron comes along. You can also observe how dragonflies, shrimp and fish use the floating wetlands as habitats. Macrophyte islands do not only offer a chance for nutrient removal but can also be a biodiversity hotspot and habitat.

First floating wetlands in a Baltic lagoon!

Together with our cooperation partner – the Federal State Institute of Agriculture and Fishery MV – we installed the first two floating islands in the aquaculture research station in Born at the Darss-Zingst Bodden Chain. The two floating wetlands, made out of stainless steel and reed stems, were planted with a variety of native emergent macrophytes: Typha latifolia, Schoenoplectus lacustris, Iris pseudacorus,  Bolboschoenus maritimus, Lythrum salicaria, Butomus umbellatus, Carex acutiformis and Juncus effesus. In this first year we want to find out which plants can adapt best to the special site conditions, grow well and remove most efficiently phosphorus and nitrogen from the eutrophicated waters. The islands are installed at the outlet of the aquaculture pond (sturgeon cultivation) and we will monitor the water quality as well as nutrient removal in the plant biomass. Besides fighting eutrohication, these floating wetlands create diverse habitats for microbes, birds and insects and can also be an aesthetic “eye-catcher” for residents and tourists in coastal regions once the flowering starts. We will keep you updated!

Stakeholder workshop in Germany: How to improve the licensing process for mussel farms?

As part of the Baltic Blue Growth project, a stakeholder workshop focusing on the new draft for the mussel farming license guideline took place in Eckernförde, Germany, on the 26th of April 2018. The aim of the workshop was to examine how to optimize the licensing process for a mussel farm. Improving the effectiveness of legal rules and state regulations is a prerequisite for improving the mussel farming potential of the aquaculture sector. Representative of all involved state authorities of Schleswig-Holstein discussed how the permit process can be simplified and how to ensure the best possible cooperation between the licensing authorities.

On the basis of an imaginary mussel farm, the participants discussed the previous approval process and debated whether there is room for improvement. On the one hand, it is not possible to simplify or shorten the procedure without undermining the regulatory goals. On the other hand, everyone agreed that efficient cooperation between the various authorities plays an important role. An advantage in any case is the early involvement of the responsible authorities. An option to improve the permit procedure could be the set up of an online platform with all the relevant documents and information that would make the internal exchange of information between authorities and companies more transparent. The results of the workshop will be incorporated in the finalization of the approval guideline, which will be published as part of the BBG project.

MORPHEUS project meeting in Essen, Germany

From 16th to 18th of April 2018, the MORPHEUS project partners met in Essen, Germany. At the meeting, the partners exchanged views on the current state of project activities and discussed initial results.

Water samples from local sewage treatment plants as well as in rivers in Sweden, Germany, Poland and Lithuania were analyzed for selected pharmaceuticals in order to estimate the concentration of trace substances in the southern Baltic Sea region. These results, in combination with data on regional prescriptions and sales volumes of drugs, should serve to understand the specific pathways and quantities of pharmaceutical trace substances and to derive appropriate measures for their reduction. This information together with an assessments of available micropollutant retention technologies will assist operators ofsewage treatment plants and state authorities with regard to future implementations of appropriate purification technologies.

As part of the project meeting, the participants visited sewage treatment plants in Dülmen and Bad Sassendorf and learned more about the use of activated carbon powder or ozone as the fourth purification stage.

Partner meeting BONUS OPTIMUS

Partners from the BONUS OPTIMUS project attended a project meeting the Leibniz Institute for Baltic Sea Research Warnemünde from the 10th – 12th of April, presenting their newest results on mussel farming to combat eutrophication in the Baltic Sea.

The focus was this time on case studies from Denmark, Sweden and Germany. Besides results on growth performances, filtering capacity or the utilization of mussels, participants discussed how suitable site selection criteria for mussel farming can be established. An essential point is that local habitants as well as tourists need to accept and endorse mussel farms in their regions. To investigate this aspect further, EUCC-D in cooperation with Aarhus University (Denmark) will carry out a survey at the Hagensche Wiek (Rügen Island) where the German mussel farm was installed in 2017.

In addition to the scientific exchange, the project meetings served as a discussion opportunity with experts from regional, national and international ministries, state authorities and research institutions.
