Published as: Transplantation of juvenile corals: a new approach for enhancing colonization of artificial reefs | Technique: Substrate addition - artificial reef, transplantation | Disturbance addressed: Pollution | Genera: Stylophora, Dendronephthya | Method: An artificial reef was constructed using a modular block deployed at a depth of 18m, a buoy 2-3m below the surface, and nine 50 x 50 x 3 cm PVC settlement plates attached vertically and horizontally between them. Coral planulae and fragments were transplanted onto the plates. Survivorship was monitored biweekly. | Post-restoration monitoring: 5 months | Authors' conclusion: The survivorship of the transplanted D. hemprichi colonies was significantly higher on the lower sides of shallower plates. Survivorship of S. pistillata colonies increased with depth when located on the vertical plates, or on the upper sides of the horizontal plates. The highest survivorship of this coral was on the vertical plates and on the upper sides of the horizontal plates, while very low survivorship was recorded on the lower sides. The results indicate that vertical artificial surfaces offer the optimal biotic and abiotic conditions (light intensity, sedimentation, colonisation by ot… | Lessons reported: Vertical artificial surfaces offer the optimal biotic and abiotic conditions (light intensity, sedimentation, colonisation by other organisms) for the survival of the two examined corals | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work. No contribution to the condition index is recorded: the source reports survival of transplanted material, which is not a measure of ecosystem condition.

Recorded result

No result recorded yet. A result is recorded when the project moves to Paused, Completed or Discontinued.

A variable shows "pending" instead of a contribution when no domain area has been set for it yet — the share of the world a project touched cannot be computed without one. The health percentages are accurate regardless.
