Matthias Mahnke

Production Manager, Project Engineer


From an early age I have been culturing aquatic organisms. Due to my studies of fishery science and aquaculture (1997-2003) at the Humboldt University of Berlin and the Leibniz-Institute of fresh water ecologies and inland fisheries I was able to scale-up my passion.

In the last 16 years I have been acting as RAS-operator, production manager, R&D-manager, instructor, project engineer and consultant. My core competencies are operation and engineering of RAS, production planning, sewage treatment and fresh water fish. I have gained most practical experience with sturgeon and caviar production.
