Bài viết này trình bày kết quả phục hồi san hô tại một số khu vực như: Khu Ramsar Vườn Quốc gia Côn Đảo (Bãi Cát Lớn thuộc Hòn Bảy Cạnh và Đất Dốc thuộc vịnh Côn Sơn năm, năm 2018–2020); Khu BTB Lý Sơn, Quảng Ngãi (Dinh Tam Tòa - Đảo Lớn, năm 2015–2018); Khu BTB Phú Quốc (Hòn Dâm Ngang và Hòn Thơm, năm 2008). | Vietnam Journal of Marine Science and Technology Vol. 20 No. 4A 2020 61 68 DOI https 1859-3097 15647 http jmst Assessment of effective coral rehabilitated in Marine Protected Areas of south Vietnam Hoang Xuan Ben Vo Si Tuan Phan Kim Hoang Institute of Oceanography VAST Vietnam E-mail hxuanben@ Received 28 August 2020 Accepted 26 October 2020 2020 Vietnam Academy of Science and Technology VAST Abstract More than 20 300 fragment corals belonging to 24 species eight genera and six families were rehabilitated in marine protected areas of south Vietnam. Mean survival rates of coral fragments ranged from 60 the average growth rate of the branched corals was mm month meanwhile the foliose coral was mm month. The survival and growth rate of corals are different among areas because each coral species has different biological characteristics structure colonies and due to differences in natural conditions each area. The results showed that the growth rate of corals will return to normal after 4 months rehabilitation. The factors affected the effective coral rehabilitation including Coral reef predators spatial competition among species environmental conditions change due to human s activities and other factors such as hydrodynamic regimes cutting fragment corals cause its injury damage. The rehabilitation and protection activities of coral reefs in marine protected areas should be continued and expanded contributing to the protection of biodivesity marine resource and sustainable coral reefs ecosystem development.
