OTC: OPTIMUS - Optimization of mussel cultures for eutrophication prevention and fish feed production in the Baltic Sea

Within BONUS OptiMus IOW will be responsible for the field work at Bay of Greifswald. Therefore, a mussel test farm will be build and used to regularly monitor changes of water quality and, in strong collaboration with the project partners, sediments below the test farm will be studied. Further, IOW will focus on the salinity depended growth modelling of Mytilus edulis and the overall impact of mussels on water transparency within the ecosystem model. Beyond the test farm, IOW will develop strategies to optimize the overwintering of the farm and use an approach to include as many criteria as possible to find the optimal site for a mussel farm. Finally, IOW will be responsible for an ecosystem assessment including potential changes due to a mussel farm and IOW will help EUCC-D to identify suitable stakeholder groups and to hold the stakeholder workshops at the German case study site.
