[Coral-List] Planting of propagated coral fragments

Hi Andrew

I'd agree with the suggestions already made, but would point out that
copper is known to be toxic to many marine organisms (eg
http://www.newscientist.com/article.ns?id=dn4391).  While the vinyl
coating is intact, it probably wouldn't present a problem.  However, the
coating will break down over time and expose your propagules to the
copper.

List,
   
  I'm hoping to begin replanting of propagated A. cervicornis material
in June/July in Montego Bay: racing the storm season.
   
  Any suggestions on methods?
   
  I am planning to break up the propagated material into 5-10cm segments
and wire them to masonry nails hammered into urchin grazed, clean reef. 
   
  Wire will be a vinyl coated copper (i'm having good success, it's
cheap, colour coded and easy to work with) but i'm interested in
suggestions on types of nail: galvanized is probably bad (?) I'm
expecting partial attachment to the reef within 2-3 weeks and overgrowth
of the nail within 5-7 weeks. Will nail rusting inhibit overgrowth?
   
  Are there other suggestions in reef attachment?
  I've looked at simple spreading, string anchoring, epoxy, concrete,
drilling-and-sticking and some more. Nails seem most secure in the
short-term.
   
  Andrew Ross

Greetings,
I'd like to announce a great opportunity to learn GIS technology and how
it 
can be used for marine ecosystem research. This course will take place
in 
the Marine Protected Area of Capo Rizzuto. Participants will have the
chance 
of  becoming successful Geographic Information System users through the
ESRI 
Authorized "Introduction to ArcGIS 9.x". Additional modules will
introduce 
the participants to GIS-based tools and techniques of marine scientists
with 
underwater and computer sessions. They will learn how to map marine
habitats 
from satellite images and verify them on the field, perform marine fauna
and 
flora surveys and find associations among all the biotic and abiotic 
components using GIS.

When: August 16-26, 2006

Where: Marine Protected Area of Capo Rizzuto - Crotone, Italy

To know more about this course you can download the pdf at:

or visit the website:

Andrew --- I had good success transplating A. cervicornis pieces (~5cm
long) on the Caribbean coast of Panama by inserting one end of a coral
piece into soft Tygon tubing.  The tubing piece was about 5 - 10 cm
long, with a diameter that formed a tight fit on the coral.  There are
many ways to anchor the other end of the Tygon tubing to
something fixed (e.g., a spike, rebar, etc., driven into the reef).
Heavy-duty, all plastic, uv-resistant, cable-ties work very well for
this.  Because of crevice corrosion, do not use the cable ties with
metal inserts, stainless or not.

Transplants were more successful if elevated above the surrounding
substratum.  Hermodice ("fire worm") attacked the segments placed at
substratum level.  The coral tissue quickly grew over the Tygon tubing.

Andrew,

If you have the capacity to drill holes, I think the
drilling-and-sticking 
method using a super glue gel (ethyl acrylate) is a good option.  One
can 
simply drill a shallow hole, squeeze in a couple mL of super glue gel,
and 
insert the base of the Acropora propagule into it.  Ethyl acrylate super

glue gel sets well underwater and is commonly used for the aquaculture
of 
Acropora and other small polyped Scleractinian corals.

You may also want to experiment with laying cuttings on large rocks and 
glueing them "sideways."  In some species of Acropora, this seems to 
stimulate a great deal of encrustation before new branches are erected.
If 
you are trying to establish colonies in rough waters, this may be a good
way 
to get them started.

Hope this is helpful,
Kevin Kocot

Hi Andrew,

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.

Karl
