Published as: Closing the circle: is it feasible to rehabilitate reefs with sexually propagated corals? | Technique: Coral Gardening | Genera: Acropora | Method: Acropora millepora larvae were induced to settle on pre-conditioned coral plug-ins, reared in the lab, and transplanted onto the reef. Corals were transplanted onto the reef in three batches: 7, 14 and 19 months after settlement. Survival and growth were monitored for 2 years after the first outplanting, more or less monthly. | Survival of transplants reported by the source: 22.2333% | Post-restoration monitoring: 24 months | Authors' conclusion: Survival rates were higher in corals that were transplanted onto the reef at larger sizes. An intermediate ocean nursery stage is critical in the sexual propagation of corals for reef rehabilitation. 3 years post-settlement, colonies were reproductively mature, making this one of few published studies to date to rear a broadcasting scleractinian from eggs to spawning adults. | Lessons reported: Producing a single 2.5- year-old coral on the reef cost at least US$60, which would constrain delivery of new corals to relatively small scales in many countries with coral reefs. | 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.
