31 new coral frames and 65 recycled frames were transplanted at Landaa Giraavaru during January. 36 of the frames were located in our new ‘Water-Villa-300’ site, and 60 frames at the ‘Parrot Reef’ site (which now totals 458 frames). We only used Pocillopora species as healthy Acropora species are still rare and live mostly beyond 12m deep.
At Kuda Huraa, 9 sponsored frames and 13 recycled frames were placed in the Channel site during January.
Coral Growth Study
To closely study coral growth, we have placed new coral micro-fragments on Perspex sheets in an aquarium, where conditions are optimal and observations can be made regularly. So far, the coral fragments are showing good health overall. Holes were drilled in the Perspex sheets and fragments were sized accordingly (so we do not use glue or fixative substances that could impact the experiment). Several species have been used on the two sheets including encrusting, massive and digitate corals.

At Landaa Giraavaru, 31 new frames were transplanted during February, at our new ‘Water Villa 300’ site. Fragments of Pocillopora species continue to be the only type of coral that we use, as healthy Acropora species are still rare and live mostly beyond 12 metres deep.
At Kuda Huraa, 19 new coral frames were made and a further 31 frames were recycled and deployed in our Channel area. Frames continue to show good health and have not been affected by predation. Frames that were transplanted with Acropora coral fragments have been doing very well; the colonies are growing nicely and now cover the cable tie that was used to attach them to the frame. Pocillopora coral fragments are healthy but are not growing as quickly. Efforts will be made to collect more Acropora colonies from the reef off Girifushi (Military Island) as they are showing to be more successful on our frames.

Coral growth study
The coral micro-fragments have been showing good progress, and the skeleton of some fragments have started covering the Perspex sheet. We have been using a program called Pix4D to render 3D images, to closely observe and study the patterns of growth.
Our Coral Taxonomy Project is still ongoing during 2017.
