Rydawi Aquaculture Services
Recirculating Aquaculture Systems (RAS)

Rydawi Aquaculture Services focuses specifically on Recirculating Aquaculture Systems (RAS) for fish production.  RAS is operationally sophisticated, complex (from an engineering perspective) and capital-intensive system for large scale fish production.  It is, we believe, the only aquaculture system able to produce fish in South Africa on a commercial scale in a manner that is both environmentally sustainable and financially viable.

Example of a RAS system (Round tanks):

To improve the prospects of developing a successful RAS project, a comprehensive, integrated approach to its formulation, execution and operational growth is required. Rydawi Aquaculture Services has developed a proprietary framework to ensure all of these elements for successful project execution are systematically and thoroughly addressed:

Rydawi Aquaculture Services has a working relationship with DRA Global which allows us to not only address engineering & design elements but also to facilitate the Engineering, Procurement & Construction Management (EPCM) element with a company that has an excellent track record in this field.
