Antigua Reef Ball Project
15, 2004 ENN News - Over 7,000 Red Mangroves used in Maiden Island Mangrove
- Fish, Corals, Algae and
Inverts present after construction of the Windward Reefball Reef. (Please
send us reports of any confirmed sightings not listed here. (More formal
report to follow)
Here are a few of the accomplishments that are world firsts....
1) We propagated (which means we created new colonies) over 5,000 coral
colonies of 30 different species
2) We rescued over 17.5+ tons of corals from dredging operations and
transplanted them onto the Reef Balls without a single coral family loss.
3) We re-established 4 new coral species lost from Maiden Island
category 5 hurricane five years ago.
4) We relocated and saved over 3000 (free living) rose corals.
5) We populated the Reef Balls with over 500 sea urchins to create
conditions optimal for coral recruitment
6) We built a near shore to offshore reef corridor to help transport
juvenile fish to adult fish habitat. We also created a large variety
inter-unit spacing changes to create the greatest possible species
7) We created a "pinnacle" reef (3 large piles of huge Reef Balls
reaching the surface in 20 feet of water and big enough to penetrate as a
scuba diver) with a "sound signature" to host potential fish
activity. To our amazement, within 3 weeks of building it, we already
a gray snapper pre-spawn event occurring with hundreds of very large snapper
schooling to spawn!
8) We created hundreds of yards of snorkeling and diving trails. All the
Pallet Ball sized Reef Balls (over 100 of them) on the trail each have 3 12
inch x 12 inch by one inch deep squares that can have snorkel trail signs
added or be left as is to serve as trail markers.
9) We added juvenile lobster recruitment mesh to several Reef Balls and have
already observed lobsters on the Reef. Other Reef Balls have a similar
material added to create invertebrate diversity. [More may be added by Nova
Southwestern as part of a study on invertebrates].
10) We have already documented 73 fish species, 71 Invertebrates, 30 Corals
and 26 Algae (plus a turtle) now on the Reef. Increases in fish counts
11) We stabilized over 9000 pounds of loose live rocks from the area to help
reduce hurricane reef damage.
12) The Reef Ball Foundation activated the Coral Propagation and Coral
Rescue volunteer teams. There were over 274 man-days of volunteer
assistance organized to conduct the project. This included expert
volunteers from Australia, England, Holland, Mexico, Curacao, France,
Italy, Antigua, Florida, Georgia, New York, Arizona, Turks and Caicos,
Mississippi, Malaysia, and more. Locals from Antigua (especially the
Optimist Club) astonished us coming out on even rainy days to assist.
13) Reef Balls have never been built faster...we had over 40 molds turning
2-4 times per day running 24-hours per day with shifts of dedicated
construction worker averaging 50 at any given time.
14) We deployed on average 60 Reef Balls each day (rain or shine), with
coral teams having transplanted the Reef Balls usually within hours of
deployment. Skilled barge crews operated in delicate coral reef areas
without disturbing the corals.
15) The documented gray snapper aggregation for spawning is the first known
formation of a fish spawning site and has major implications for future fish
17) We (intentionally) increased the genetic diversity of several species of
coral (Finger, Elkhorn, Staghorn, Lettuce, Brains, and soft corals) to
strengthen the reef from coral diseases and man made stresses.
18) We documented corals "basing" (growing out over the Reef
Balls) in just
3 weeks including Staghorns, Elkhorns and Finger Corals. This
they are healthy and will survive well.
19) The Reef included hundreds of "Feature" Reef Balls and an
variety of sizes and shapes (including all reef habitat classes such as
voids, ledges and thickets)....all of these variations were designed to
mimic specific reef functions.
20) In total, the project will include over 3000 Reef Balls modules.

formed a multi-disciplinary team to provide recommendations
for the restoration of Maiden Island near shore aquatic environments and its
beaches. A Reef Ball submerged breakwater has been built including use of
the Reef Ball Coral Propagation and transplant adapter system. The team also
met with Department of
Environment (Environmental Protection and Fisheries) group for
additional design considerations.

- "Stanford Development Group in Antigua has conducted a project through the
Reef Ball Foundation to install approximately 3,000 Reef Balls around Maiden
Island. The project was the largest ever coral propagation
and transplant program. We created over 10,000 new coral
colonies, including threatened Staghorn (A. cervicornis) and Elkhorn
corals (A. Palmata). The Reef Balls will serve many purposes
including protecting seagrasses from boating scars, stabilization of the
island's beaches to create better conditions (less siltation) for corals and
other marine life, and as substrate to create a richly diverse coral reef.
The Reef Ball Foundation has activated its Coral Propagation and Rescue Team
that is a network of individuals throughout the world who have been trained
in Reef Ball methods of coral propagation. So far, 26 of the available
pool of 100+ of these experts have been used in the project.
Additionally, Antigua's Optimist Club has offered local volunteers to assist
in the effort and other volunteers from the community are expected to
receive training in the methods to continue the work in other locations
throughout Antigua. An Oceanographer, Alfredo Torruella, Ph.D.
of the Caribbean Oceanography Group has selected the appropriate locations
and sizes for the Reef Balls and Dr. Lee Harris of FIT is doing specialized
engineering for the project which will include a variety of specialized
anchoring techniques to fit the bottom characteristics of Maiden Island.
Harold Hudson (A.K.A. “The Reef Doctor”) has assisted the
Foundation in providing specialized biological designs for "Layer
Cake" and "Thicket" Reef Balls made using the Reef Ball molds
and his unique molding techniques. In total, the project used 7
different sizes of Reef Balls of which there are 9 different styles and 5
different anchoring solutions. Not only is this the most extensive use
of all Reef Ball technologies, it was also completed in record time. "

Stanford Development Company purchased 50 Reef Ball molds but the license
for using them has been suspended pending resolution of outstanding invoices
associated with the project. Use of these molds for any project without
the advanced written consent of the Reef Ball Foundation is a violation of
