Abstract:
This study aims to study the effect of light spectrum and intensity on Galaxea
fascicularis. Photosynthetic rates of Galaxea fascicularis were determined under
different light spectrum and intensities. The specimens were exposed to white, yellow,
primary green, deep blue, medium amber and plasa red light treatment for three hours.
Control was conducted by treating the corals under dark condition. Each light treatment
was supplied with a constant intensity of 11.25 µmolm-21
