KOCHI: The central government is reigniting plans to protect coral reefs and creating new ones to upend the tourism sector. Coral reefs will be planted in selected areas as per suggestions from experts. From the study conducted, it was learned that the Vizhinjam region in Kerala and Thangassery in the Kollam and Tirumullavaram sea regions are best fit for coral reef plantation.

A study led by CMFRI Senior Research Fellow Alvin Anto said that the coral reefs destroyed due to coral bleaching can recover their full shape if provided a conducive atmosphere. It was after this report that the government decided to bring back coral reefs in favourable locations across Kerala. The study was conducted in Lakshadweep where coral reefs are in abundance.

Reefs are coloured by algae called zooxanthellae, a single-celled micro-organism that lives in the tissues of coral reefs. If these increase and ocean temperatures rise, the algae will be expelled by the reefs. With this, the reefs will lose colour and become white. This condition is called 'coral bleaching'. Coral reefs are found in areas where the temperature is below 29 degrees Celsius. The aim of the project is to restore coral reefs by sustaining algae.

Planting the peeled part from the coral reef of Lakshadweep in a favourable area in Kerala will do the trick. The favourable conditions include the mandatory aquatic presence of fish and algae. For that, fish can be reared by placing artificial ponds.

Coastal construction activities should be controlled and made environment-friendly. Shades can be installed in coral reef areas to provide protection from the strong sun. However, there are many practical difficulties with this method.
