Monthly report updates from our Reefscapers coral biologists at Kuda Huraa and Landaa Guraavaru.
You may also be interested in our extensive report on Coral Bleaching (2016), last year’s Reefscapers Diary (2017), and the public gallery Coral Frame Collection to view photographs of your own sponsored coral frame as part of our Reefscapers coral propagation project.
During January, at Landaa Giraavaru we made 33 new coral propagation frames and recycled a further 50 frames, and at Kuda Huraa we made 16 new frames. We continue to line the Water Villa walkways with our small-sized frames, and hope to attract herbivorous grazing fish to the area to control algal growth by extending outwards towards the natural reef. We are siting larger frames along the boat channel at approximately 9m depth, close to large healthy colonies of Acropora species.
A storm at the start of the month displaced and even flipped some of our coral frames, so we righted these frames and verified their GPS mapping coordinates. We also noticed some juvenile Pocillopora coral colonies were showing signs of bleaching (on our frames and the natural reef), although no Drupella snails were seen.
Acropora coral colonies from the reef crest remain our go-to source for new propagation fragments, with new coral growth seen to quickly encrust the frame and cable tie (more successfully than Pocillopora fragments).
Many hands make light work !

New Experiment – ‘Multiple Breaks’
In order to test whether or not fragments with multiple breaks can survive, two small coral frames were created. Photos were taken of each side of the frame, so the fragments can be seen clearly; we hope to gain a better understanding of the survival and growth rates of different coral fragments.
