Published as: Experimental Assessment of Coral Reef Rehabilitation Following Blast Fishing. 19:98–107. | Technique: Substrate Stabilisation | Disturbance addressed: Destructive fishing | Genera: n/a | Method: Large scale experiment testing rock piles in four types of configuration, designed to limit encroachment by rubble: 1) complete coverage, 2) rock piles, 3) spur and groove parallel to current, 4) spur and groove perpendicular to current | Post-restoration monitoring: 72 months | Authors' conclusion: Coral cover, recruit size and fish abundance/diversity was higher on restored sites, compared to control sites. No clear data on different substrate enhancement types. High variability in success of various substrates stabilisation techniques between sites and stabilisation types. Success was highest at moderate current sites, compared to sites with high or low current. | Lessons reported: Some heavier corals stopped being supported by the rubble piles - stabilisation of piles may be needed to ensure longevity. Technique only relevant where access to quarried rocks is relatively easy and cheap. | 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.
