[Coral-List] Artificial reef - cement or metallic /w electrical stimulation?

[Philippe Sanchez]

Hi all,

I've been looking at some artificial reef projects, specifically in the
UAE. Reef balls seem to be quite popular. A friend recently told me about
increasing growth and survival rate by applying a small electrical current
(I'd never heard of this before). I read the paper (Goreau, T.J. 2014) and
it seems very promising. I wondered why this wasn't more well known??
Perhaps it's too expensive for people to set up?

Does anyone here have any experience working with such a project or can
give some insight on the pros and cons of this innovative method?

Thanks!
