Coral Propagation – Monthly Progress

At Kuda Huraa this month, we transplanted three new frames, kindly sponsored by guests. In addition, we monitored and repaired 84 frames, recycled 50+ old frames, and retagged 30+ frames. We also moved 110 frames at the Water Villas site to create four new geometric patterns (example in photo).

At our Pyramids (made from relocated rescue corals) we have been battling a coral disease outbreak that is causing paling and tissue loss. Similar symptoms have been observed at nearby reef Reethi Faru, suggesting that a pathogen may be spreading around N. Malé Atoll (in particular, affecting Acropora millepora and A. echinata). We are closely monitoring our Pyramids, promptly removing any affected corals, and isolating vulnerable colonies to minimise spread.

At Landaa this month, we transplanted 23 coral frames, kindly sponsored by guests (eight), online (four), and the Resort (eleven), adding a total of 1045 coral fragments to the reef. We also monitored (cleaned, repaired, photographed) a total of 646 coral frames, and lifted 20 buried frames out of the seasonally shifting sands; this recycled 300 fragments on degraded frames, plus a further 395 fragments at Parrot Reef. We have also been continuing our long-term project to restore and remap the Blue Hole site.

Montipora foliosa

This month, we had the opportunity to fragment a colony of Montipora foliosa that had been grown on a large ceramic plug by our colleagues on the local island of Fulhadhoo, where it thrives naturally to form a beautiful coral garden. Some fragments were carefully transplanted to frames at the Water Villas site (slow current), others to a breakwater frame (strong currents). Small fragments were also attached to ceramic nubbins in open-flow tanks in our Lab, to determine whether epoxy or superglue would cause any coral paling.
