Published as: Elaborating an Eco-Engineering Approach for Stock Enhanced Sexually Derived Coral Colonies. | Technique: Coral Gardening - Nursery Phase | Genera: Stylophora | Method: Testing different methods of growing corals in situ from sexually-derived coral larvae. Larvae were collected during spawning, encouraged to settle on plastic film, and housed ex situ for 1-2 months. Settlers were then placed on plastic pins, and transferred to mid-water nurseries. Trays were covered with mesh cages for 9 months. Two orientations (horizontal/vertical) and nursery substrates (fishing net/ropes) were tested, although this experiment was not fully factorial (no horizontal position… | Survival of transplants reported by the source: 45.06% | Post-restoration monitoring: 22.6 months | Authors' conclusion: 80% of corals can survive until two years, when reared ex situ for 1-2 months, and then housed in in-situ mid-water nurseries. (Note: mismatch between reported % survival and figure. Survival % reported here derived from figure 5) | 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.
