“…Angka rata-rata pertumbuhan fragmen anakan karang ini relatif lebih lambat jika dibandingkan dengan transplantasi metode gantung di dasar perairan (5-7 meter), yaitu 6,9 mm/bulan sampai dengan 12,8 mm/bulan, dengan lama pemeliharaan 6 (enam) bulan (Mustafa, Oetama and Sidiq, 2020). Pelambatan pertumbuhan ini disebabkan oleh tumbuh suburnya kompetitor berupa alga pada nursery ground yang diduga karena tingginya limpahan nutrien dari kegiatan tambak udang vaname.…”

The status of the condition of Indonesia's coral reefs is mostly categorized as moderate and damaged. Relatively inexpensive and easy-to-implement rehabilitation methods need to involve the participation of many stakeholders. The method of transplanting coral fragments by hanging (floating) from the surface of the water will be more efficient, especially in their maintenance. This study aims to investigate the most suitable water depth to support the growth and survival of the transplanted coral fragments. A non-factorial Completely Randomized Design (CRD) field experiment with 3 (three) treatments, namely different seedbed depths, 2 m, 4 m, and 6 m respectively. Each treatment was repeated 4 (four) times. The results of analysis of variance showed that the absolute growth rate of coral fragments transplanted by hanging from the surface of the water at different depths (2 m, 4 m, 6 m) showed no significant difference (P-value > 0.05). This shows that the environmental conditions at a depth of 2 m-6 m are relatively the same, so that on average all coral fragments have almost the same growth potential (0.29 cm/month). Meanwhile, the survival rate obtained is also very high (> 90%). These results confirm that the method of transplanting corals by hanging from the sea surface is technically feasible and gives good results. This will help many stakeholders to be involved in optimizing the economic potential value of coral reefs, as well as increasing participation in the conservation and rehabilitation of coral reefs.

“…Currently, there are many choices of methods for transplanting coral reefs (Johan et al, 2008). Some of the methods often used are the net and substrate rack method (Mustafa et al, 2020), concrete (Dedy Kurniawan et al, 2021), nets and shards (Saputra et al, 2020), natural substrates (Hermanto & Utara, 2015), the biorock method (Siahaan et al, 2018) and the spider skeleton (Tenilo & Boalemo, 2021). Each method has its advantages and disadvantages and must be adapted to the transplant site.…”

The world's coral reefs are under threat from human activities through pollution and habitat changes. This condition is influenced by several factors, such as human activities and natural phenomena. Many efforts have been made by humans to overcome or repair coral reef ecosystems that have been damaged. One of the efforts made is to carry out coral transplants. The main goal of coral transplantation is to improve the quality of coral reefs such as increasing live coral cover, biodiversity and uniqueness of coral topography. The stages of the method carried out in the research include mapping the bottom of the waters (sounding); mapping conditions of water cover; transplantation process and monitoring. This study used the spider skeleton method for the transplant media. The results showed that the percentage of live coral cover ranged from 10% - 25% and it was found that rubble cover dominated up to >70%. During the monitoring process, it was found that algae dominated almost all of the transplant media. The high nutrients and the lack of algae-eating fish resulted in a high algae cover found on the surface of the structure and had an impact on the death of the transplanted corals. Efforts are being made to regularly clean algae to increase the survival rate and replant dead coral
