The marine environment contains a stunning variety of creatures ranging from single-celled organisms to the blue whale. The oceans are also home to coral reefs, one of the most diverse eco-systems on the planet. Humans (over)use the oceans in many different ways. Demand for protein-rich and healthy fish products is rising, while natural stocks are declining. Increasing demand for fish can be satisfied with aquacultures, but many of these aquacultures are not sustainable if fish meal and fish oil are used, which, in turn, come from fishing. The consequence of this is an additional reduction in the fish living freely in the oceans.
Maintaining healthy oceans supports climate change mitigation and adaptation efforts.
Examples of our contribution
- Amino acids and amino acid derivatives, which were developed especially for aquaculture, can replace much of the fish meal and fish oil. It is possible to completely do without fish oil by using biotechnologically created omega-3 fatty acids. We developed these together with our partner DSM. They are produced with the help of marine algae. One kilogram of oil produced in this way replaces up to 60 kilograms of wild-caught fish.
- We have established high standards and infrastructures at our sites to clean our wastewater. Wastewater is carefully controlled, for example, by regular sampling and using continuously operating measuring equipment.
