Super algae solution for bleached Phi Phi coral

KRABI: Super algae is to be deployed in the Phi Phi national marine park in a world-first attempt to revive bleached coral.

Bleaching has affected about 80 per cent of the coral in Hat Noppharat Thara – Mu Ko Phi Phi National Park’s protected area, said the park’s chief Sarayuth Tanthien on June 23.

Mr Sarayuth blamed rapid tourism growth and high sea temperatures for the bleaching.

Red demarcation flags have been set up at coral restoration zones, where swimming and snorkeling is not allowed, explained Mr Sarayuth.

“We are going to use super algae in a world-first attempt to restore the bleached coral.”

The super algae, also known as blue-green algae, is being tested in laboratories and will be introduced to the affected areas as a nutrient-rich foundation to encourage restoration of the marine ecosystem.

“Meanwhile, we are asking for the government’s help to enforce restrictions preventing tourists from disturbing those areas,” said Mr Sarayuth.
