AWI has conducted scientific research on macroalgae from the very beginning. Many scientific topics on biology, ecology, reproduction, etc. have been studied on macroalgae from the North Sea and Baltic Sea as well as from the polar regions and the tropics. Since the mid-1990s, questions about the aquaculture of algae have increasingly become the focus of scientists. Macroalgae as a marine resource should be cultivated in the coastal sea and made available for human nutrition. Possible hurdles, such as reproduction for mass culture, technical solutions for farming, and economic questions were to be clarified. In the meantime, the field of application has been extended to the open ocean to enable large-scale mass cultures in multi-use concepts. Today, we are approaching land-based facilities again for certain questions, where controllable optimal conditions can be set in RAS. This keynote lecture provides an overview of this development and identifies unresolved issues.
