Published as: Differential physiological responses of two congeneric scleractinian corals to mineral accretion and an electric field. | Technique: Substrate Enhancement - Electric | Genera: Acropora | Method: Field experiment testing benefits of electrochemical vs electric field in coral nurseries. Treatments: 5 x 42 nubbins grown on electrified steel frames, 5 x 42 nubbins grown on bamboo frames within electrical field, 4 x 42 nubbins grown on bamboo trays outside of electric field (control) | Survival of transplants reported by the source: 88.6667% | Post-restoration monitoring: 4 months | Authors' conclusion: Direct exposure to electrical current (ie attached to a cathode) did not increase survival of coral fragments after 4 months. Growth was fastest for both species inside the electric field. A pulchra had higher zoox and chlorophyll a densities on cathode compared to electric field and controls. | Lessons reported: The suggested benefits of mineral accretion technology vary between species. Except for chl a concentrations, the cathode had a significant adverse effect on all measured variables for A. yongei but not for A. pulchra. A pulchra had increased zooxs and chlorophyll a densities on the cathode, yet did not exhibit a corresponding fast growth and low mortality. | 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.
