Feasibility study of a sustainable marine aquaculture in the Baltic Sea (Schleswig-Holstein)

 

The Ministry of Energy, Agriculture, the Environment and Rural Areas Schleswig-Holstein concluded in the Aquaculture Strategy for Schleswig-Holstein that there is a potential for nutrient extractive aquaculture (mussel- or seaweed production) or integrated multitrophic aquaculturein the Baltic Sea. Integrated multi-trophic aquaculture (IMTA) provides the by-products, including waste, from one aquatic species as inputs (fertilizers, food) for another species. The fed aquaculture (e.g. fish) component is combined with the extractive (e.g. mussels) aquaculture to create balanced systems for environment remediation. So far no technical scale IMTA facilities have been established in the Baltic Sea in Schleswig-Holstein and therefore there are no reliable economic data and estimations on environmental impacts (especially for specific site conditions). This feasibility study will evaluate the potential of a successful and sustainable establishment of IMTA or extractive aquaculture facilities in coastal waters of the Baltic Sea in Schleswig-Holstein.
