Fish farming is an essential tool in improving food security and reducing poverty among smallholder farmers in low-income countries. However, the success of such initiatives relies heavily on access to locally manufactured fish feed.

This project aimed to address this challenge by developing the machinery necessary for on-farm fish feed production. It was a collaborative effort between the Natural Resources Institute of the University of Greenwich in the UK and Savanna Circuit Technologies Ltd in Kenya.

The team utilised Simulation-driven Participatory Technology Development to design a solar-powered multipurpose hammermill that could grate fresh ingredients into a mash for drying and milling the dried ingredients into a powder. Additionally, a solar-powered pelleting machine was also developed.

With access to locally manufactured fish feed, farmers can improve their fish stock and harvest yields, leading to increased food security and income generation. By employing participatory technology development methods, the project ensured that the machinery met the specific needs of the community it was designed for.
