During October, we transplanted 27 new sponsored coral frames around both resorts, using ~2,000 harvested coral fragments for our transplanting and maintenance work.
Coral Spawning Event, October 2021
An initial sign that coral colonies are ready to spawn is the presence of gametes within the coral tissue, that look like tiny white eggs initially, which then grow in size and develop colouration (pink/orange).
On 19 October at Landaa Giraavru, we first spotted eggs within various Acropora species of corals.
26 October – A synchronised spawning event took place at 19:57, involving many coral species, and lasting 20 to 30 minutes. The gamete bundles float to the surface and we were able to collect them using custom-made egg collection devices.
On 27 October at Kuda Huraa, we observed coral spawning occurring from 20:00 to 20:15 (Maldives time, GMT+5). We successfully harvested some eggs, and placed them into our aquarium for observation, along with a dead coral skeleton as a settlement substrate. Some eggs became attached by 20:45 (30 mins after spawning) but we did not see coral larvae.
From our notes, we observed this spawning event occurred:
– 1.5 hours before the lowest tide (which was at 21:42);
– Seven days after the full moon (which was on 20 October);
– One day later than in Landaa Giraavaru (Baa Atoll).
