Signify has launched new Philips solar fish grow lights that help to optimise farming for ponds, relying solely on the power of the sun.
Research by the South China Agricultural University in a commercial size trial at a tilapia farm using 60 solar luminaires in a 7,000m2 pond confirmed a 10% increase in fish growth and a 10% reduction in feed conversion ratio, meaning that fishfarmers need less feed per kilogram of fish.
Based on an earlier study in cooperation with the Ocean University of Shanghai, which showed similar results, South China Agricultural University started the 117 day trial at a tilapia farm in Taishan, Jiangmen, Guangdong in the south of China.
Remo Lansbergen, general manager aquaculture at Signify, said the results showed a breakthrough in tilapia farming efficiency improvements. “It was very good to see that the results we obtained in the laboratory test in Shanghai could be repeated in an actual farming situation in the south of China,” he said.
The Philips solar fish light is easy to install and only one luminaire is needed per 100-150m2 of pond surface. The luminaires, equally spaced in the pond, are attached by rope to the centre line or to each other to keep them in place and provide light for up to six hours after sunset.
