Abstract

Three species of corals, two are hard coral, Porites sp. and Pavona sp., one soft coral, Sinularia sp. was propagated using three different type of natural light intensities treatment which are one layer of horticulture net, two layers of horticulture net, and three layers of horticulture net in three different tanks. This study is to determine at which light intensity promotes the best growth rate of the corals. This study also looks at the comparison of the growth rate of the corals under the different light intensity. The corals were propagated for four weeks. The corals is measured weekly for the wet weight, wet in the air, width and height. The growth rate of the three species of the corals is measured weekly. Every treatment between species shows no significance difference (p>0.05). Sinularia sp. shows the highest growth rate in week 3 under one layer of horticulture net treatment (2.0538 Gday⁻¹), Porites sp. shows the highest growth rate in week 2 under two layers of horticulture net treatment (5.1333 Gday⁻¹), and Pavona sp. shows highest growth rate in week 1 under one layer of horticulture net treatment ( 4.4762 Gday⁻¹). This study showed that corals that get appropriate light intensity will increase the growth rate.
