1) Reef Ball Development Group, Coastal Reef Builders, Inc. and Eternal
Reefs will attend the Camp Timpoochee Workshop on Artifical Reefs on Feb.
9th. This workshop will focus on a re-opening in the Large Area Permits
off the coast of Florida with greater restrictions on the types of
materials that can be used. Of course, Reef Balls are approved for use in
the Large Area Permits.

County Natural Resources Department. Here's the text,

Prolific Sea Life Abounds at Sarasota County Artificial Reefs
By Karen F. Burnett, P.G., Manager, and Michael Solum, Environmental
0n November 12, 1999, monitoring dives were conducted at two Sarasota
County artificial reef sites (M-17 and M-4). Todd R. Barber, President of
the Reef Ball Foundation, Inc. and Foundation, Inc. in Sarasota,
organized the monitoring excursion. Mr. Barber is the inventor of the
current concrete reef ball design used in many artificial reefs around the
world. Scuba Quest, Inc. in Sarasota donated the dive boat. The dive group
consisted of State artificial reef coordinators and members of the Gulf
and Atlantic States Marine Fishery Commission.
The first dive was at the M-17 reef ball site, located 10 miles west of
the Venice Inlet. Growth on the 200+ reef balls was astonishing. Though
only three years old, every reef ball harbored lots of hard corals, 14
types of tunicates (sea squirts), and oculina (ivory bush coral) up to 2
feet long. Fish species were varied and abundant. Divers observed
thousands of fish around the site, including juvenile and adult jewfish,
grouper, snapper, amberjack, hogfish, filefish, and tropical fish, such as
blue angels, grey angels, and beaugregories.
A sea turtle, beautiful purple and yellow nudibranchs (shell-less snails),
and a variety of starfish were also reported. The coral growth and marine
life usage in only three years at this reef is truly remarkable,
especially when compared to the life on reefs constructed of other
The second dive was conducted at the M-4 artificial reef site, located
approximately 7 miles west of New Pass. This site consists of concrete
culverts that were placed ten years ago and 225 concrete reef balls that
were deployed one year ago. The coral growth on the reef balls far
surpassed the growth on the ten-year old culverts! Again, divers observed
prolific and varied sea life in and around the artificial reef structure.
Porgies were in schools so thick that they obscured the view of the reef
balls. Hundreds of flounder, grouper, lizard fish, snapper, Spanish
mackerel, barracuda, and large jewfish were also observed.
It was also noted at both artificial reef sites that no subsidence or
sinking of the reef balls has occurred. This was a problem with earlier
artificial reef materials such as bricks/blocks and concrete culverts. The
concrete reef balls are built with larger flat bottoms to reduce
subsidence when placed on soft sand or mud bottoms.
We thank Mr. Todd Barber, President of the Reef Ball Development Group,
for his report on the monitoring dives and for contributing to the
tremendous habitat success of Sarasota County's artificial reefs.
We are out of room for today's update so more later...
