Aquaculture has been one the World’s fastest growing Agri-sectors for the past decade and a half.  Much of this growth has been driven by the need to find alternative fish supplies to rapidly dwindling fish stocks both marine and freshwater, also from increased demand in fish consumption.

Fish Farming and in particular Tilapia farming can and must provide relief to many of these people by the farming of high quality fish protein.  To achieve this, fish farms must be established in both urban and rural areas.


Over 30 years of practical experience and research led to the formation of Rydawi in 2014.  The development of the One tank fish farming system Intensive Tilapia Farming System has met the demand and interest of Tilapia farmers in Africa.


Rydawi believes that the small scale farmer is vital to the food security of any economy.  Fish Farming opens up new markets and economies which yield good returns, which in turn can be used to further develop other farming activities and diversification.  Often farmers are at the mercy of external and uncontrollable elements such the economy, markets, diseases, and the financial institutions.  One tank fish farming system farming can change that!
























The one tank fish farming system -  AN INTEGRATED, SIMPLE   SYSTEM


The One tank fish farming system is an aquaculture system designed around Recirculating Aquaculture System design principles. It offers a unique and simple way for anyone to enter the world of fish farming with the lowest cost of entry, lowest running costs and lowest technical requirements.


The One tank fish farming system is packed into itself meaning that the entire farm can be packed compactly into containers, shipped and then erected anywhere.


One tank fish farming system will work with many fish species.


One tank fish farming system has been designed to address the need to farm fish in environments which are not generally suitable such as in a low temperature area, or logistically challenging – being far away from suppliers and markets, and not environmentally friendly due to perceived pollution and fish disease risks of farming in cages or lakes.



The Attributes of the APU system are:

  • Individual self-contained tanks that are pre-assembled
  • Completely scalable and modular
  • Suitable for many species of fish, Tilapia, Catfish, Carp,
  • Lowest power consumption model on the market today
  • The systems have been designed to be light, compact and easily transported, thus savings on logistics, shipping taxes and duties
  • Low costs systems both in Capital and Operating costs, maximizing the return on investment and profitability
  • Small footprint and space utilization
  • Fish can be introduced to the system immediately after filling with water
  • 100% waste water recovery used for irrigation and or hydroponics.
  • Easy to learn operating skills with little prior experience.
  • Water use has been minimised by the filter designs and operations
  • The Farm is low maintenance = more time spent farming
  • Offers a high level of biosecurity by running self-contained systems


How much does it cost?


Each environment and farmer’s requirements are different and therefore might entail different costs. Please view a guideline in Annexure “A” at the end of the document for the cost for a single tank production system to farm Tilapia over a 6-month period starting with 250 fingerlings, and adding 250 fingerlings to the system every month for 5 more months.


The cost is R30 000 excl VAT


The one tank fish farming system has been designed to be profitable above all else. The lowest capital cost on the market means that profit margins are higher, and earlier than with other farm models. This lowers financial risk, ensures more financial resilience/sustainability and means higher profits from the outset.
