You might call the Reef Ball an
underwater condo for fish, especially
grouper and snapper. After
the Reef Ball is in the water
awhile, marine organisms begin
to grow, small fish move in and
then larger fish.
Bill Lindberg, associate professor
at the University of Florida?s
Department of Fisheries, says
an artificial reef can boost fish
population by about 8 percent.
If a reef site is over-fished, it can
result in a decrease fish population.
Reef Balls have holes that
not only go into the module but
between the walls. The large open
area in the center is designed to
provide fish shelter. The holes
are designed to create vortexes
which feed the invertebrates
and corals. Many other artificial
reefs assume that surface area
or profile alone...
