Coral reefs play an important role in marine ecosystem but have been
seriously damaged by climate change and human’s activities.
Rehabilitation together with other local management activities is
likely to improve ecosystem resilience. Survey data indicated that
coral reefs are threatened in Southeast Asia and Vietnam in
particular. Previous studies have shown that, at some trial locations
in Vietnam the survival rate was high from 65% - 100% after 3 - 5
months. However, it is unclear that if reef rehabilitation using
transplanted hard corals leads to an effective result in Con Co island
of Vietnam. In this study, we aim to examine the survival rate, growth
rate, and the increase in the number of axial corallite of transplanted
hard corals after 8 months conducting experiment. Here we collected
coral colonies in diversity locations to transplantation sites. Our
results shown that, the survival rate of the hard coral fragments
(n=360) was high (71.1%). Growth rate of branching, coral increased in
size with 85,4%. It is also show that, the increase in the number of
axial corallite was recorded in 81.3% colonies. These results suggest that, reef rehabilitation using transplanted hard corals can be used to recover coral reef in Quang Tri province of Vietnam.
