Feeding the rural poor and hungry in the 21st Century with technology


The need to produce fish in Africa increases with every fish taken out of our natural resources and with every child born. For 70 years when fish farming first occurred in Africa, little has changed, a large number of our countries are facing a major decline in accessibility to fish as a major source of protein.






Rydawi Fish Farms News - March 2017


The SuperActiFlo Bio Media used in the FarmInABox bio filter and mechanical filter is a highly efficient and user friendly media.  The original media was developed some 10 years ago, for waste water treatment and for fish farming.  The spaghetti wheel design and the fact that the media is buoyant and that is has a large surface area makes it an ideal bio filter medium.


The SuperActiFlo media is moved about by aerating the bio filter, this moving bed sloughs off any dead bacteria and detritus ensuring the media remains active with healthy living nitrogenous bacteria. The moving bed system requires very little maintenance and interaction and no physical removal or cleaning of the media.  The high surface is +/-900m2 per meter cube means much smaller, more efficient filters to do the same job.

Rydawi Fish Farms News - February 2017


Rydawi has exported systems to DRC, Malawi, Zimbabwe, Tanzania, Burundi, Angola, Kenya and we now have over 125 systems in the market.  This represents a major boost to Tilapia production in Africa.  Recently we have airfreighted single FarmInABox systems to Tanzania, Kenya and Burundi and will soon be sending Systems to Nigeria.  The compact packaging and light weight design and construction of the systems makes for cost effect shipping and logistics.  Once our clients receive their units and stocked them with fingerling their skills are quickly developed, so that when the rest of the units arrive via sea freight they are already proficient with farming in our systems.  The package size of a complete ready to install system is currently 1200x1000x1000mm and it weighs less than 150Kgs.

David and William farm in a box system can be said to be the greatest invention in the aquaculture industry because even the greatest invention in history are coming from pieces of equipment what differs it’s how those equipment are connected to form one well-functioning unit. It is a pleasure for me to be part of these winning team, it might be tough but victory is certain at the end.”
