Baltic Blue Growth – Initiating full scale mussel farming in the Baltic Sea


Dr. Peter Krost

Project description:

CRM is involved in the EU project “BBG” with a total of 18 international project partners. The project management is located in the municipality of Kalmar in Sweden, in the hands of Lena Tasse.

The project focuses on marine aquaculture with mussels (Mytilus edulis), as mussels have the potential to improve water quality and counteract eutrophication in extractive crops. The aim is to expand shellfish aquaculture, which has hitherto been operated only on an experimental scale, to a viable business model. For this purpose, the ecological and socioeconomic conditions should be explored and optimized in order to be able to produce marine biomass in the form of mussels on a larger scale. The biomass produced is intended as a substitute for conventional fish meal z. B. in feed or fertilizer use and at the same time develop maximum benefits for the nutrient reduction of the Baltic Sea.

Task of CRM:

For the Bay of Kiel, suitable locations for mussel farms should be identified and the criteria for site selection should be defined. The environmental impact of shellfish farming on the marine environment should be quantified and assessed using biotic and abiotic factors in a test farm.

Task of the project partners:

The operation and monitoring of further test farms in other Baltic Sea regions is the responsibility of the other project partners. Furthermore, the modeling of socioeconomic scenarios for the establishment of mussel farms, taking into account possible climatic changes and modeling the ecological carrying capacity as well as the influence of mussel farms on the nutrient balance of the Baltic Sea region.
