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.

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 project

Users

The In-Pond Raceway System (IPRS) technology offers numerous advantages, particularly in enhancing food security and promoting climate resilience. By incorporating this technology into your project, you can harness its potential to positively impact farming communities and mitigate the effects of climate change.

To integrate the IPRS technology into your project, consider the following activities and prerequisites:

Identify design and size of raceway that matches available capital and production objectives,
Provide access to a high-quality water source and supply of affordable electricity for constant flow,
Train staff on operation and maintenance to minimize energy and feed cost.

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.

Consider engaging a team of trainers to provide comprehensive training and support during project installation, including costs for training and post-training assistance.

Develop communication materials such as flyers, videos, and radio broadcasts to promote the benefits of IPRS fish farming.

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.

Collaborate with agricultural development institutes and hatcheries to implement the IPRS technology effectively in your country.

By following these steps and considerations, you can effectively integrate the In-Pond Raceway System technology into your project and contribute to improved food security and climate resilience in your community.

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.
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.
Aeration:
- Implement continuous forced aeration systems. These provide high levels of dissolved oxygen, which is vital for fish activity, feeding response, and overall health.
Stocking Fish:
- Introduce fish into the raceway channels. The IPRS design allows for higher stocking densities compared to traditional pond farming.
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.
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.
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.
Feeding:
- Provide appropriate feed for the fish. The efficient water circulation and oxygenation in the IPRS system contribute to improved feed conversion ratios.
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.
Cleaning and Maintenance:
- Periodically clean and maintain the raceways, aeration systems, and other components of the IPRS to ensure its continued effectiveness.
