SPIMOS, as an offshore spirulina modular cultivation-supply system, provides a new and sustainable way of food supply. The cultivation device part makes full use of the abundant water and light resources in the sea, and ultimately realizes the harmless cultivation of spirulina platensis, a high-protein algae. By modularizing its design, the whole aquaculture system can be quickly adapted to different water surface spaces. As a result, a complete protein supply chain has been built at the service system level, from farming to processing to selling, from farmers to processors to users.
