1. Project Overview

Location:  Kenya

Species farmed: Tilapia (primary species)

System type: HDPE deep-water floating cagesDistance from shore: Approx. 1 km

Annual output: ~10,000 tons

Start year: 2018

The project was launched to address a critical fish supply gap in the region, while promoting environmentally responsible aquaculture and local economic growth.

2. Key Features of the Deep Water Cage System

✅ HDPE Floating Frames:High-density polyethylene structures provide buoyancy, UV resistance, and durability in tropical freshwater environments.

✅ Reinforced Knotless Nets:Polyethylene nets reduce fish injury, improve water circulation, and deter predators.

✅ Secure Mooring System:Anchors and mooring lines hold cages in place even during strong currents or storms.

✅ Offshore Positioning:Cages are located in deep, clean waters to reduce pollution and space conflicts with traditional fishermen.

✅ Scalable & Modular:The system supports expansion and species diversification for future growth.

3. Benefits & Impact

🌱 Sustainability:Deep water placement minimizes ecological impact on nearshore areas and supports water quality through natural exchange.

🐟 Fish Supply Growth:Tilapia production helps meet domestic demand and reduces reliance on imported fish.

🌍 Export Potential:The model serves as a scalable platform for African aquaculture expansion across other nations and export markets.

4. Visual Overview of the Deep Water Cage System

Here’s a typical structure of a deep-water cage farming system

Key Elements:

Circular HDPE frame: Buoyant and rigid

Vertical net walls: Extend downwards into deeper waters

Anchor lines: Connected to the sea/lakebed for cage stability

Floating walkway platform: For feeding and maintenance

5. Conclusion

This African offshore fish farming project highlights the potential of deep water cage technology to solve regional food shortages, improve livelihoods, and promote sustainable aquaculture practices. With proven scalability, this model represents the future of fish farming—not only in Africa, but globally.
