Christian Fernsby ▼ | April 19, 2021
The study, which took place at a commercial scale tilapia farm, was carried out by researchers at South China Agricultural University, using new solar powered fish grow lights, designed by Philips.Article continues below
The lights produce spectral light specifically designed to suit many fish species, including tilapia. In the trial, 60 solar luminaires were deployed in a pond of in a 7,000 m2 pond.
Based on an earlier study, in cooperation with the Ocean University of Shanghai , which showed similar results, South China Agricultural University started the trial in a live setting.
This new trial, done at the tilapia farm in Guangdong, in the south of China, also suggested that the lights had 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.
According to the company, the Philips solar fish light is easy to install and only one luminaire is needed per 100-150 m2 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. The best operation is achieved with clean solar panels and LED unit. ■ What to read next
