[Coral-List] Planting of propagated coral fragments

We have never used nails, but we place mesh trays of cable-tied live rock
bases (scleractinia rock from depth covered in coralline algae), which have
coral nubs (5-6cm) super-glued into pre-drilled holes, onto tables of
galvanized rebar. Its for export, not re-planting. But at times we have
experimented with a dive operator here in getting tourists to adopt a
cultured coral frag and plant it on the reef. In those cases we take our
frag on the rock base and have the tourist place a small amount of z-spar
epoxy underneath the base and carefully 'plunk' it in place. Over time it
creates a little colony. Wish we could do more of that but the business has
to survive as well. [as an aside here we are interested to learn about
funding opportunities to do more of this as well as direct reef restoration
using our Vanuatu staff]
There may be some concern with using non-galvanized metal in proximity to
coral. As discussed by others on this list in Dec/Jan, iron released through
rusting may contribute to cyanobacteria growth. We had issues with this
prior to our switch to galvanized. Part of the list recommendation was to
promote grazers as much as possible.
Good luck with your efforts.
