Published as: A basic experiment of coral culture using sexual reproduction in the open sea. | Technique: Substrate Addition - Artificial reef | Disturbance addressed: Bleaching | Genera: n/a | Method: Settlement tiles were placed on a site with high natural recruitment, and recruitment analysed. Three types of settlement tiles were tested, 1) regular pottery stone tiles, arranged in towers 2) circular pottery's stone rods, pitted with 4 mm diameter holes, 3) square limestone pillars, pitted with 4 mm diameter holes. The towers, rods and pillars were arranged in a stainless steel frame (42cm x 45 cm x 40 cm). The plates were deployed on a shallow site, and remained there over the coral spawni… | Post-restoration monitoring: 3 months | Authors' conclusion: The number of settlers on the square stick was 4 times higher than on the cylindrical stick. MOst settlers on plates were on the underside | Lessons reported: Holes on settlement sticks may have been too shallow to protect corals from predation | 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.
