In-Pond Raceway Systems for Fish Farming

Revolutionize your fish farming with IPRS for maximum yields and sustainability.

The In-Pond Raceway System (IPRS) is a groundbreaking aquaculture technology designed to enhance fish farming efficiency. It achieves this by maintaining uninterrupted water flow and implementing effective waste disposal methods. This system allows for significantly higher fish stocking densities, with levels reaching up to 150 kilograms per cubic meter. In comparison to traditional pond farming, IPRS has been shown to yield a remarkable 200-300% increase in fish production. By focusing on water quality, aeration, and waste management, IPRS sets a new standard for sustainable and high-yield aquaculture practices.


This technology is TAAT1 validated.

  • Low Fish Yields: Traditional pond farming limits fish productivity per area, reducing profits.
  • Fluctuating Water Quality: Unstable water conditions hinder fish growth and health, impacting overall productivity.
  • Poor Waste Management: Inadequate waste removal causes pollution and harms fish health.
  • Disease and Stress Risks: Conventional methods expose fish to higher disease and stress risks.
  • Resource-Intensive: Traditional methods demand extensive land and labour, raising costs.
  • Inefficient Feed Use: Inadequate water circulation and oxygen levels lead to inefficient feed conversion.
  • Environmental Harm: Inefficient resource use and waste management harm the environment.


  • Higher Stocking Densities: IPRS boosts fish productivity by allowing more fish per area.
  • Optimized Water Conditions: It maintains consistent, high-quality water, promoting healthy fish growth and reducing stress.
  • Effective Waste Management: IPRS swiftly removes fish waste, preventing water contamination and enhancing water quality.
  • Healthy, Fast-Growing Fish: The system recreates a natural environment, reducing disease risks and ensuring robust fish growth.
  • Efficient Resource Use: IPRS requires less land and labour, making it a cost-effective option for fish farming.
  • Enhanced Feed Efficiency: It improves the conversion of feed into fish biomass.
  • Environmental Responsibility: IPRS reduces pollution and conserves resources for sustainable aquaculture.

Key points to design your business plan

Utilizing the In-Pond Raceway System (IPRS) technology offers a solution to effectively manage pests and diseases, enhance fish yield and quality, and promote sustainable aquaculture practices, thereby improving the livelihoods of diverse farming communities.

As essential collaborators, suppliers of IPRS equipment are necessary partners. Considering that the technology is available in various countries like Kenya and Nigeria, it's crucial to account for delivery costs and potential import duties.

The cost structure varies for IPRS technology. The cost of building an IPRS varies depending on the size and the materials used. A reinforced concrete raceway of 5 m long, 1.2 m wide and 1.2 m deep costs about 4,000 USD. If constructed properly, an IPRS should have a life of 5 to 10 years. Despite their higher initial investment, IPRS have a lower break-even variable cost point per harvest as compared to traditional static ponds.

For better optimization of the technology, consider associating it with complementary technologies such as All Male Tilapia Fingerlings with Greater Yield and Uniformity Fast Growing and Hybrid African Catfish.

Fish farmers dependent upon IPRS technology may achieve a 30% increase in profit margin while at the same time practicing water conservation.

  1. Design and Setup:

    • Begin by designing the raceway system within an existing pond. This involves creating channels or raceways within the pond to facilitate fish containment and water circulation.
  2. Water Circulation:

    • Install equipment like airlifts or paddle wheels to generate water flow within the raceways. This continuous circulation is crucial for maintaining optimal water conditions.
  3. Aeration:

    • Implement continuous forced aeration systems. These provide high levels of dissolved oxygen, which is vital for fish activity, feeding response, and overall health.
  4. Stocking Fish:

    • Introduce fish into the raceway channels. The IPRS design allows for higher stocking densities compared to traditional pond farming.
  5. Waste Management:

    • As fish produce waste, the water flow generated by the system helps in efficiently removing this waste from the raceways. This prevents waste buildup and maintains water quality.
  6. Water Filtration:

    • The unused water in the pond serves as a natural biological filter. It undergoes filtration processes and is recirculated back to the production area.
  7. Monitoring and Maintenance:

    • Regularly monitor water quality parameters such as oxygen levels, temperature, and pH. Conduct routine checks to ensure the equipment is functioning optimally.
  8. Feeding:

    • Provide appropriate feed for the fish. The efficient water circulation and oxygenation in the IPRS system contribute to improved feed conversion ratios.
  9. Harvesting:

    • When fish reach the desired size for harvest, use standard aquaculture practices for harvesting. The IPRS system facilitates better inventory estimates, making harvesting more efficient.
  10. Cleaning and Maintenance:

    • Periodically clean and maintain the raceways, aeration systems, and other components of the IPRS to ensure its continued effectiveness.
