Coral spawning is an annual event where corals simultaneously reproduce by releasing millions of tiny egg and sperm bundles into the water. Each bundle must find another bundle from the same species to fertilise. Mass spawning increase the likelihood of finding and fertilising a matching bundle. The corals get cues from the lunar cycle, water temperature and tides for this synchronised breeding.
Our team on Tioman Island has been monitoring coral spawning on the Island since 2013. On Tioman Island, the major spawning happens during full moon in April, while a much smaller scale happens during full moon in October. Spawning happens at night and usually last 2 to 3 days.
Last month, our team is out again to monitor the mass spawning event. This year, the monitoring was joined by Department of Fisheries Malaysia, Pahang too.
