Bio-Rock is a technology that uses low voltage electrical
current on artificial underwater structures to encourage growth
of Corals and other reef life. Experiments with the technology
worldwide have shown that it can help counteract some of the
difficult environmental factors affecting coral growth. In
conjunction with Save Koh Tao, Big Blue and a consortium of
other dive schools launched a pilot project a few years ago to
see if the technology would be successful here. The pilot
project has been so successful that a new larger Bio-Rock was
constructed in 2008. Now that the structure is in situ, regular
dives are scheduled to the site for two main reasons. The first
is to continue to plant broken Coral pieces on the structure and
the second is to continue to monitor the growth of the test
subjects. When the structure was first finished, test subjects
were placed on the structure and tagged so that their growth
could be monitored. This information is collated by Marine
Conservation Koh Tao for scientific purp
