Lee County’s latest artificial reef, which went down Friday,
is a whole new ballgame — Reef Ball, that is.

For only the second time, the Lee County Division of Natural
Resources has bought prefabricated modules to make a reef,
spending $16,440 on 84 concrete structures called Reef Balls.
Most of the county’s reefs, on 19 sites in the Gulf of Mexico
and Charlotte Harbor, are made from donated material, such as
concrete culverts, bridge rubble and boats.
But Reef Balls, distributed by Reef Innovations Inc., whose
manufacturing plant is in Sarasota, have been getting rave
reviews from Florida and around the world.
One satisfied customer is Nova Southeastern University’s
Oceanographic Center, whose scientists placed Reef Balls in an
area of coral reef off Fort Lauderdale that was damaged when a
U.S. submarine ran aground in 1993.
“We’re using Reef Balls, not as a restoration item per se,
but as a module to test scientific experiments,” said Richard
Dodge, dean of the Oceanographic Center. “We’ve had great
success with that as a module. We like them. They’re doing well.
Other people have used them in other ways, and I think they’ve
been successful as well.”
With the attitude of “why buy the cow if the milk’s free?”
county marine biologist Chris Koepfer decided to test the
expensive Reef Balls against reefs made from donated material.
“I’ve been satisfied with how the donated material performs,”
he said. “I really want to compare Reef Balls, which cost a lot
of money, to material that doesn’t cost money to see if there is
a corresponding increase in productivity.
“These things better show me a factor of 10 improvement over
the other stuff.”
Koepfer chose the ARC Barge reef site, 15 miles off Sanibel in
60 feet of water, for the experiment because several other
artificial reefs are already there, including a barge, concrete
culverts, concrete pilings, three 25-foot-tall steel radio
towers and concrete tetrahedrons (the first modules the county
bought).
Having all these reefs close to the Reef Balls, which look a
little like Hostess Sno Balls with holes (for fish to hide in),
will make comparisons easy.
Using state and federal grants, which cost Lee County
taxpayers nothing, Koepfer bought 24 5-feet-tall, 2-ton Reef
Balls and 60 that are 3 feet tall and 1 ton.
His idea was to create four “patch reefs,” each with six
large modules surrounded by 16 small modules.
The deployment Friday was more difficult than anticipated,
certainly more difficult than most artificial reefs.
With many reefs, including culverts, pilings and bridge
rubble, the material is barged to the site and simply dumped
into the water.
But Keopfer’s plan called for the Reef Balls to be placed in
precise relation to one another.
To do that, buoys were tied to the large Reef Balls before
they were lowered by a crane from a McCulley Marine Inc. barge.
The buoys were to show the center of the ring, so the small
modules could be placed accordingly.
But the buoy lines kept getting twisted, slowing down the
process, and county engineering technologists Mike Capps and
Paul Stancati spent much of the day in the water untangling the
mess.

Another problem was the pins that held the Reef Balls to the
cable often didn’t release when the modules reached the bottom
the first time, and several attempts had to be made.
Finally, high winds and currents pushed the barge around,
making accurate placement of the modules even more difficult.
Apparently longing for the simpler method of dumping reef
material, Koepfer referred to the Reef Balls several times as
“that fancy schmancy material.”
After 41⁄2 hours of tangled buoy lines and frustration, the
Reef Balls were all in place, not exactly where they were
supposed to be, but close enough.
The first fish visitors were three goliath grouper, five
barracuda and a bar jack, all of which probably swam over from
the nearby radio towers to see what the commotion was all about.
“I’m sure these will make an excellent reef,” Koepfer said.
“But next time I come out, I think I’ll wear socks, because it
will have to knock my socks off to justify the expense.” |
