With the declining state of Philippine coral reefs, the need for conservation and rehabilitation efforts are deemed crucial to sustaining ecological, biological and economic recovery in the reef system. However, there is yet a concrete and workable policy to be implemented in restoring and rehabilitating our reef areas aside from establishment of marine protected area (MPA). Here, we explored the prospects of coral restoration by demonstrating experiences in San Fernando, Masbate (Ticao Island) combined with the practices of the National Coral Restoration Program. In this project, some 20,000 coral nubbins utilizing ‘corals of opportunities’ were reared in 40 coral nursery units (CNUs) for six months and achieved 80% survival. They were then out-planted (c. 20,000 sq m) inside an MPA to ensure their protection and increase in live cover.  The fragments were attached to dead corals using epoxy or tied in concrete nails using cable ties. Four coral genera were used namely Acropora, Seriatopora, Pocillopora, and Stylophora. About 70% coral survival was achieved after two months of transplantation. Involvement of the LGU, community and the private sector is crucial to project success. Results of the transplantation indicated effectiveness and viability of the CNU system to complement coral transplantation.

Kawasan Kepulauan Seribu merupakan bagian dari wilayah Daerah Khusus Ibukota Jakarta, terletak pada posisi geografis antara 106°25’-106°40’ BT dan 05°24’-05°45’ LS. Daerah perlindungan laut adalah daerah yang ditutup secara permanen di mana semua kegiatan penangkapan ikan dan kegiatan lain dilarang. Tujuan penelitian ini untuk mengetahui kondisi lingkungan di daerah tersebut pada bulan April dan Juli 2007. Pengamatan kondisi ekosistem terumbu karang dilakukan dengan metode transek garis (line intercept transect) sepanjang 50 m sejajar garis pantai dan pengamatan kondisi oseanografi lima stasiun pengamatan. Hasil penelitian menunjukan kondisi oseanografi di daerah perlindungan laut Pulau Pramuka layak untuk kehidupan biota laut dengan konsentrasi oksigenterlarut berkisar antara 2,55-4,19 mg/L, salinitas berkisar antara 32-32,5o/oo, kecerahan berkisar antara 2-10 m, dan derajat keasaman (pH) berkisar antara 7,85-7,99. Kondisi kesehatan karang adalah sedang dan baik dengan persentase tutupan karang berkisar antara 30-75%. Seribu Islands region located at 106°25’-106°40’ E and 05°24’-05°45’ S which is a part of Jakarta Province. Marine protected area is a closed site permanently where extractive activity is prohibited, mainly fishing activity and the aim of this program is to conserve coastal resource. The aim of this research was to know environmental condition of Pramuka Island marine protected area at Seribu Islands. The research was done at marine protected area of Pramuka Island in April and July 2007. Monitoring of coral reef ecosystem was done with line intercept transect method along 50 m parallel with shore line and oceanography condition at 5 stations. The result of this research shown that oceanography condition at marine protected area of Pramuka Island was suitable for marine biota life with dissolved oxygen between 2.55-4.19 mg/L, salinity between 32-32.5o/oo, transparency between 2- 10 m, and pH between 7.5-7.99. Coral reef healthy condition is medium and good with percent covered between 30-75%.

Restoration Method

Counteracting the worldwide trend of coral reef degeneration is a major challenge for the scientific community. A crucial management approach to minimizing stress effects on healthy reefs and helping the recovery of disturbed reefs is reef protection. However, the current rapid decline of the world's reefs suggests that protection might be insufficient as a viable stand-alone management approach for some reefs. We thus suggest that the ecological restoration of coral reefs (CRR) should be considered as a valid component of coral reef management, in addition to protection, if the applied method is economically applicable and scalable. This theoretical study examines the potential applicability and outcomes of restocking grazers as a restoration tool for coral reef recovery – a tool that has not been applied so far in reef restoration projects. We studied the effect of restocking grazing fish as a restoration method using a mathematical model of degrading reefs, and analyzed the financial outcomes of the restocking intervention. The results suggest that applying this restoration method, in addition to protection, can facilitate reef recovery. Moreover, our analysis suggests that the restocking approach almost always becomes profitable within several years. Considering the relatively low cost of this restoration approach and the feasibility of mass production of herbivorous fish, we suggest that this approach should be considered and examined as an additional viable restoration tool for coral reefs.

The coral reef ecosystem has been continuously degraded in various parts of Indonesia, including the Anambas Islands. This research aimed to discover the content of Potassium Cyanide (KCN) accumulated on corals and the effect on indicator fishes abundance in the Anambas Islands. This research was conducted at 25 observation stations in the Anambas Islands National Marine Protected Area. The potassium cyanide (KCN) content was tested with the principle of titration and distillation. The coral samples used ranged from 10-20 g diluted in 100-200 ml distilled water. The method used to determine the abundance of indicator fish was underwater visual census or UVC, which recorded fish in every station. This research recorded 307 fish individuals from 14 species of the Chaetodontidae family. Potassium Cyanide's content on corals was high ranging from 0,009-0,032 mg/L with an average 0,0205 mg/L. We concluded that there was a negative correlation between the content of Potassium Cyanide  (KCN) on corals and indicator fishes abundance, which means the higher the Potassium Cyanide content (KCN) is on corals, the lower the indicator fishes abundance will point out.
