Published as: Development of Restoration Technology for Coral Reefs Using “Marine Block™.” JFE Technical Report. | Technique: Substrate Addition - Artificial reef | Genera: Acropora | Method: Development of a substrate suitable for attachment of coral transplants (Marine Block), as well as the development of a coral settlement device. The marine block was made of slag, a byproduct of the steel industry, which is primarily made of CaCO3, facilitating recruit settlement and the attachment of coral fragments. The settlements devices were used to capture coral larvae for outgrowing in nurseries, and later transplanted onto Marine Blocks after 1 year. | Post-restoration monitoring: 72 months | Authors' conclusion: Marine rock receives 2 times more settlers than a concrete block. Transplanted Acropora nasuta spawned 6 years after transplantation on to Marine Block. | Lessons reported: Marine Block can be used to settle corals on, | 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.

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.
