Red tide threatens marine ecosystem in Gulf of Thailand: Expert
The Marine and Coastal Resources Research Centre (Central Gulf of Thailand) is monitoring the red tide phenomenon, which could significantly impact the Gulf’s marine ecosystem.
This came after reports of red tide occurrences in Prachuap Khiri Khan and Chumphon from 2019 to 2024, and in Surat Thani from 2011 to 2024.
The phenomenon, caused by a rapid increase in certain plankton species, is commonly observed from February to April and October to December each year, said the centre director Natthawadee Bantiwiwatkul.
She warned that the plankton blooms could deplete oxygen levels in the water, posing a serious threat to marine life. The centre has urged relevant agencies to closely monitor the situation and advised tourism operators and locals to avoid water activities to prevent potential skin irritation, she said.
Aquatic farmers should remain vigilant as the red tide phenomenon can lead to a mass fish death, she warned.
