[Coral-List] electric bio reef technology

[Marlowe Sabater]

Below are published controlled experiment we did in
the Philippines in 2000.

Sabater MG and Yap HT (2004). Long-term effect of the
induced mineral accretion on growth, survival and
corallite properties of Porites cylindrica. Journal of
Experimental Marine Biology and Ecology 311 (2):
355-374.

Sabater MG and Yap HT (2002) Growth and survival of
coral transplants with and without electrochemical
deposition of CaCO3. Journal of Experimental Marine
Biology and Ecology 272: 131-146.

Longitudinal growth was not significant. Significant
growth was found to be in a few centimeters above the
accreting zone thereby increasing girth rather than
length. Enhanced girth growth were present only in the
presence of electricity and girth growth decreased due
to competition to the algae recruiting on the fresh
bare substrate.
