Paradigm shift in marine AquacultureMade in Germany
:O u r Vis io n
• land-based production of seafish and marine organisms
• securing food chain for civilisation out of a biosecure environment
• sustainable and environment-friendly production
• rapid reactivity to shifts of the market
• profit maximization by high quality
• water and nutrient recycling
