Published as: Multivariate responses of the coral reef fish community to artificial structures and coral transplants | Technique: Substrate Addition - Artificial reef | Genera: Acropora, Pocillopora | Method: The effects of artificial structures and coral transplants on fish abundance, number of species, and community composition were examined during a two-year study at three locations. Three experimental treatments (10 x 10 m rubble plots (a.) left untreated, (b.) covered with concrete structures, and (c.) covered with a combination of structures and coral fragments) were monitored using monthly underwater visual censuses. | Post-restoration monitoring: 24 months | Authors' conclusion: At the site with the lowest coral cover and structural complexity in the ambient reef, fish community responses were most marked, with an 8-fold increase in fish abundance in the Structures + Corals treatment compared to the untreated rubble plot. At the other two sites, abundance and number of species in the experimental treatments did not surpass that of the natural plots. | Lessons reported: Reef context is important in the selection of appropriate restoration measures. Results may differ depending on condition of the ambient reef. | 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.
