Before the marine ecosystem on Nha Trang Bay is at an alarming level, under the seabed of Hon Mun core area, corals have died white, Khanh Hoa has launched a pilot solution to allocate 28 hectares of sea surface to a management unit. , coral reef conservation.
Timely solutions of Khanh Hoa
On June 12, Khanh Hoa Provincial People’s Committee issued a decision to assign 28 hectares of sea surface in Nha Trang Bay to Van San Dao Joint Stock Company to implement the project “Conservation and restoration of biodiversity in the coastal waters of Bai Tien”. of Nha Trang Bay” with a term of 5 years.
The decision of Khanh Hoa Provincial People’s Committee clearly states that this project is not for business purposes but to conserve and restore biodiversity in the coastal waters of Bai Tien in Nha Trang Bay at a total cost. currently nearly 15 billion.
It is known that the project consists of main items using 1.9 hectares of the seabed that was previously free of coral, with a depth of 4 – 4.5 m as an artificial reef.
The artificial reef will be made by experts with hollow, non-toxic materials to relocate the group of cultivated corals for restoration. Experts monitor the growth of corals during the incubation process.
It can be said that the piloting of coral reef restoration on Nha Trang Bay is a timely solution of Khanh Hoa in the context that the decline of marine ecosystems is at an alarming rate.
The mass death of corals in Nha Trang bay is real
These days, public opinion as well as scuba diving lovers in Nha Trang Bay Marine Reserve are shocked by the news of mass coral deaths on Hon Mun Island – the core area of Nha Trang Bay Nature Reserve. Many pictures show dead coral covered with white seabed that makes everyone feel sad.
An actual survey at Hon Mun shows that mass coral deaths are real.
The seabed in the northeast and southwest of Hon Mun island is covered with a layer of dead coral hundreds of meters wide, the ecosystem has almost disappeared, and the schools of swimming fish are gone. Meanwhile, on the shore in these areas, tons of dead coral are washed up by the waves and piled up.
Nha Trang Bay Marine Protected Area includes the islands of Hon Mun, Hon Tre, Hon Mieu, Hon Tam, Hon Mot, Hon Cau, Hon Vung… and surrounding waters. The total area is about 160 square kilometers, including 122 square kilometers of water around the islands.
In particular, Hon Mun is a strictly protected area because it has the richest and most diverse ecosystem in Vietnam. This place is likened to a coral paradise with a particularly rare and precious ecosystem that few places have.
According to Dr. Hoang Xuan Ben, Deputy Director of Nha Trang Institute of Oceanography, if you want to determine whether corals in the core area of Nha Trang Bay Marine Protected Area are “bleached” due to the influence of natural disasters or man-made, it is necessary to direct survey.
Previously, Mr. Huynh Binh Thai, Head of Nha Trang Bay Management Board, admitted to the media that there was a mass death of coral in the marine protected area of Nha Trang Bay, especially the core area of Hon Mun. And the problem of mass coral death, this unit reported to the People’s Committee of Nha Trang City.
According to Mr. Thai, there are many causes of coral death in Nha Trang Bay, of which are mainly natural disasters, namely 2 storms No. 12 at the end of 2017 and storm No. 9 in 2021. After the storm No. 12, coral damage in Nha Trang Bay is up to 80-90%.
According to Mr. Thai, in addition to storms, climate change factors and global temperature rise also negatively affect corals not only in Nha Trang Bay but also in other areas such as Phu Quoc and Kien Giang.
Mr. Thai said the construction, sea encroachment, harm to coral is there.
Some longtime diving guides said that in the past, the coral reef area of Hon Mun was very beautiful, everyone who came here wanted to dive in this area to see. However, the situation of white coral dying in a large area makes anyone scuba diving here feel sorry.
In the southwest area of Hon Mun, corals cover the seabed with white. On the shore tons of dead coral, washed away by the waves, piled up.

To preserve it, it needs the cooperation of all people, the State takes the lead
Before this incident, reply on ZingProf. Dr. Nguyen Tac An, former director of Nha Trang Institute of Oceanography, said that Nha Trang Bay in general and the coral ecosystem in the bay are under great pressure from economic development. A series of works encroaching and filling the sea has made coral reefs disappear, which is very harmful to the future.
According to this expert, to have a coral reef takes thousands, even millions of years. If an area is “bleached”, it may be forever irreversible.
He considers economic development as an inevitable trend of society, but not so that it ignores the sustainable factors of the natural environment and cultural values of that land.
Mr. An said that in order to preserve the marine ecosystem, including corals, it is necessary to have the cooperation of all people. “The state has to take the lead in conservation, then it has to take care of the livelihood for the people, because when they are not guaranteed their livelihood, they will definitely go to the sea to exploit and the consequences, we already know. “, analyzed the doctor.
At the same time, according to him, in the immediate future, it is necessary to immediately stop exploiting marine resources in the area in Nha Trang Bay, strictly control sea leveling projects to clean up the area. After that, scientists must be invited to research and set up long-term and sustainable projects.
“This is a serious problem and needs the management agency to step in, and choose the optimal solution to protect the coral reefs that have not been or are less affected,” he emphasized.
