The overfishing of the seas and the limnic fishing grounds in recent decades has led to global rethinking and an increasing number of land-based aquaculture facilities. However, these require large quantities of high-quality feed and result in a considerable burden on the environment due to their high inorganic wastewater emission. Therefore, it is essential for this industry to find intelligent solutions for cost reduction and sustainability.
Together with our partner, the fish farm Christophersen (Bornhöved), Sea & Sun Technology and our team have combined the fish aquaculture with the microalgae production to close the biogeochemical carbon, nitrogen and phosphate cycle as far as possible. Within this project, we still feed fish with conventional feed with the aim of substituting this feed with algae feed. Similar to the higher plants, algae need sunlight, water, carbon dioxide and inorganic nutrients to grow your growth. Inorganic residues from fish wastewater can be used as a valuable substrate for the cultivation of algae.
