As part of the Save Koh Tao coral nursery program, we help to maintain and manage 146 reef balls that make up an artificial reef in the bay

We tagged 24 corals in July 2011 and photograph and measure the samples every 3 months or so

Unfortunately only 8 of the 24 samples are still in place - we need to revisit how we attach the corals to the concrete reef balls so as to withstand the monsoon storms 

However, the good news is that survivors are growing and look really health!
