Published as: Effects of substratum on the growth and survivorship of Montipora capitata and Porites lobata transplants | Technique: Coral Gardening - Nursery Phase | Genera: Porites, Montipora | Method: One single colony per species was collected to coral nursery in Ānuenue Fisheries Research Center, 132 fragments (2-3 cm length) generated per species. 3 fragments of each species were attached to the respective substratum (size of substratum area ~10x10cm to 118x18cm) using two part marine epoxy. Natural substrata, mostly volcanic in origin were used, including black and red ʻAʻā lava, types of gray amygdaloidal basalt, gray ignimbrite, brown rhyolite breccia, and white amorphous coral skeleto… | Survival of transplants reported by the source: 83.2222% | Authors' conclusion: Apart from glass attachment (50% survival), survival onto other substrata was >70%. Hence it seems there is no distinct substratum affinity. | Lessons reported: Study limited to only one colonie of each species, further investigations need to include more colonies. Coenosarc tissue could not be measured after 184 days, due to fusion between fragments. Hence fragments should be attached further apart to avoid this issue. | 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.
