Figure 4. (a) Control corals grown in extremely poor water quality habitat steadily lost weight while electrified
corals grew very fast over 16 weeks. When the power was cut they started to decline like the controls,
but immediately resumed growth when power was restored. This shows that coral growth stimulation is a property of the actively applied field, and does not have residual effects. Data from plotted in; (b)
ATP concentration in micromoles per gram of tissue is shown as a function of electrical current. A five
times increase in ATP is seen at the peak. Data from, plotted in.
