Up to 70 % of the coral fields around Krabi’s Phi Phi Island also have bleaching issues, according to the Department of National Parks and Wildlife Conservation ( DMCR ), and seven coral bleaching sites have been discovered in Moo Koh Surin National Park in Phangnga.
On May 12 and 13, a study into the bleaching circumstance and water temperature measurements were carried out. According to the investigation, 5 to 50 % of the coral reefs in Moo Koh Surin National Park have experienced bleach.
The worst scenario was seen near Koh Torinla, where half of the islands at abyss of two to 10 feet, generally fruit coral, were reported to be fully bleached.
Additionally, according to the research, 30 % of reefs at the same depth were said to have yellow colors. The bleaching situation stood at 30 % in Ao Tao and Ao Chong Kad, 20 % in Ao Trian, 10 % in Ao Mae Yai, and 5 % in Ao Suthep and Ao Pakkard.
The national area has been closed for the rainy season, but it will resume on October 15th, according to the area.
However, some areas around Phi Phi Island in Krabi are partially closed due to bleach, which has affected more than 50 % of the coastal coral sites in the area, said Yuthapong Damsrisuk, commander of Hat Noppharat Thara- Mu Koh Phi Phi National Park.
According to the garden, snorkelling and scuba diving are suspended at Kai Island, Khangkhao Bay, Rai Lay Bay, Daeng Island and Yavasum Island.
Otherwise, the marine regional park has created new snorkeling locations.
