KHÁNH HÒA — Nha Trang City People's Co妹妹ittee has proposed to install solar-powered cameras to monitor and protect coral in Hòn Mun Area after severe coral bleaching was reported there.

Huỳnh Bình Thái, head of Nha Trang Bay Management Board, said that the cameras would be installed on the island to monitor fishing boats and submersibles in the conservation area.

Underwater diving cameras were also proposed to facilitate the observance of coral growth

Along with the installation of cameras, the Việt Nam-Russia Tropical Centre and the Nha Trang Institute of Science and Technology for Aquaculture under Nha Trang University will pilot coral restoration in some areas of Hòn Mun. They then would choose the optimal method to restore coral on a large scale.

Nha Trang Bay is nearly  二 五0 square kilometers wide, and one of  一 六 marine protected areas in Việt Nam.

It has many corals and the richest and most diverse ecosystems in the country. It is also famous for diving beaches, attracting tourists to scuba dive and see the ocean floor.

However, coral in some areas in the bay has seriously declined. Notably in Hòn Mun conservation area, more than  一0km from Nha Trang City, coral coverage declined from more than  五0 per cent seven years ago to just about  一0 per cent now, depending on specific areas.

At some locations around the island, hundreds of square metres of coral were damaged, and in some areas, severe coral bleaching occurred.

Coral bleaching occurs when corals are stressed by changes in conditions such as temperature, light, or nutrients, and they expel symbiotic algae living in their tissues, causing them to turn white.

Khánh Hòa authority last month decided that from June  二 七, swi妹妹ing and diving activities were suspended in some areas in Nha Trang Bay, especially Hòn Mun island.

"Now, people can only dive in Hòn Rơm area and only divers with professional licences are allowed,公众Thái said.

Currently, the management board is coordinating with the Việt Nam-Russia Tropical Centre to reclassify the coral areas in Nha Trang Bay, and reco妹妹end which areas are allowed to operate tourism activities and which are not. — VNS
