Eindhoven, the Netherlands – Signify (Euronext: LIGHT), the world leader in lighting, has launched new Philips solar fish grow lights that help to optimize farming for ponds, while harnessing the power of the sun. It provides spectral light specifically designed to suit many fish species, including tilapia. The grow lights enable fish farmers to increase fish productivity and efficiency. Research by the South China Agricultural University in a commercial size trial at a tilapia farm using 60 solar luminaires in a 7,000 m2 pond confirmed a 10% increase in fish growth and a 10% reduction in feed conversion ratio (FCR), meaning that fish farmers need less feed per kilogram of fish.
Based on an earlier study in cooperation with the Ocean University of Shanghai1 , which showed similar results, South China Agricultural University started the trial in a live setting. This new trial, done at the tilapia farm in Taishan, Jiangmen, Guangdong in the south of China, proved the impact of the new solar fish lights, confirmed a 10% improved growth and found a positive effect on water quality. The commercial size trial lasted 117 days and resulted in an additional 1,770 kg of tilapia that was harvested compared to the reference ponds.
