Published as: Creating stocks of young colonies from brooding coral larvae, amenable to active reef restoration | Technique: Coral Gardening - Nursery Phase | Genera: Stylophora | Method: Testing the performance of a spat-rearing tool for a brooding coral species. Two prototypes of a new settlement apparatus and one original apparatus made of Petri dishes lined with preconditioned transparency (Mailer's paper) disks were stocked with 3730 planulae. Survival and growth were monitored in the lab and in an ex situ nursery. | Survival of transplants reported by the source: 90% | Post-restoration monitoring: 5 months | Authors' conclusion: Four months after transplantation, more than 89% of colonies survived and grew to form 3D structures. | Lessons reported: 676 person-hours are required to create 10,000 5-month-old genotypes of equal size to small branch fragments. Allows farming of large quantities of colonies originating from sexually produced planulae, may enhance local populations' genetic variability. Inexpensive and easy to perform in remote places. | 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.
