Coral Line by: Mauro & Stephanie Gabriele

Coral Type: Digitate

Coral species: Acropora humilis

This colony is the exact same one we fragmented for Coral Line 012 back in June 2014! The colony grew back after we fragmented it the first time, and so we were able to use it again. Let's see if the survival and growth match line 012. We have since used this same colony for one more line!

Update 2017: The photograph for the 1.5 year mark was a tricky one to take due to the amount of fish that have taken up residence in this nursery! You will see no update for survival of the line at 1.5years yet, as we are having some technical issues with our graphs which we are currently working to iron out, but I do know that following this year's El Nino event, this line was slightly affected and a few colonies are showing partial mortality (you can see from the photo) which has impacted on the overall growth of the line. A few colonies also died, leaving 17 colonies still alive. Before transplantation we plan to snip off any dead bits, which should help the regrowth. Line 012, which is of the same donor colony has shown a much stronger growth rate but showed a higher mortality rate during the bleaching, where we lost about 7 out of 50 colonies. You will also notice that despite the line being 1.5y old, it is still in the nursery - this is because we have had an outbreak of coral eating starfish on our reef, and have decided to leave the lines in the nursery until this issue is taken care of. We hope to transplant in March 2017, which will be the 2 year mark for this line.
