Under study: Corals found in the Gulf of Mannar. RAMANATHAPURAM: It could be the beginning of a new chapter in combating diseases against coral reef, one of the most spectacular ecosystems of underwater world, in the country. As a first step towards waging a long battle against the destructive practices followed by humans causing diseases to corals, the Gulf of Mannar Marine Biosphere Reserve Trust (GOMBRT) has appointed a team of marine scientists to find out the diseases which have affected the corals and to find reasons and ways and means to fight against it. Coral system in Gulf of Mannar, particularly around 21 islands, is considered as one of the richest systems in Asia thanks to its wide raging varieties of corals. Though corals have also found their place in Andaman Nicobar islands, Lakshaweep and Gulf of Kachch, little has been known about the diseases of corals. Except some information about diseases, there are no reliable materials available in the country about coral diseases. In this background, the GOMBRT has initiated a study to find out the diseases infected on corals in Gulf of Mannar. Speaking to The Hindu, V. Naganathan, Eco Development Officer, GOMBRT, said there were chances that some patches of corals in Gulf of Mannar could have been affected due to both internal and external reasons. Though there was no major devastating effect on corals due to diseases, it had to be stopped. All diseases, causes and other details had to be documented so as to take remedial measures and to create awareness among the people on the need to conserve the precious corals. He said black band, white band, red band, yellow band diseases were among the prominent diseases affecting corals. Biological stresses such as bacteria, fungi and viruses and non biological stresses such as increased sea surface temperatures, ultraviolet radiation and pollutants. Scientists believed that the diseases could be due to deteriorating water quality associated with human made pollutants and increased sea surface temperatures, Mr. Naganathan added.
