To try and answer these questions we set up some experiments in the Kwanini Marine Conservation Area where we have been measuring, photographing and recording the location of the coral recruits on four permanent concrete blocks on the seabed since August 2017. We have carried out three surveys of these blocks to-date; August 2017, March 2018 and August 2018 and we have gathered data regarding the number of recruits, how quickly each one grows, as well as losses between each survey period.
The data collected so far suggests that the concrete blocks are a suitable medium for initial coral settlement however the coral recruits are not developing into mature colonies. This could be due to the orientation of the concrete (the blocks are vertical in the water column) or the prevailing current. As part of our research we want to monitor different mediums, orientation in the water column and locations for coral recruitment to determine which is the most suitable, with a view to aiding reef restoration within the KMPA and beyond.
