The article highlights the efforts to enhance Baltic fisheries, particularly cod populations, through the creation of artificial reefs. Initiated in the 1990s by the German Research Institute for Agriculture and Fisheries of Mecklenburg-Western Pomerania, the project has received EU funding and has led to the construction of two reefs. These reefs, located in Nienhagen and Rosenort, have been shown to significantly improve underwater biodiversity and provide vital habitats for various fish species. The research also suggests that these structures have attracted more fish and have been beneficial for the survival of young cod. The project is set to continue under the guidance of the Fraunhofer Institute for Graphical Data Processing in Rostock, with plans for an ocean technology center, further research, and the development of aquaculture opportunities around the reef structures.
