Bart's question stimulated a lot of anti capitalistic rhetoric.
So big business should not be involved with artificial reefs? Do you
suppose Panasonic plans to make artificial reefs from discarded TV
sets? Seriously, some big-business-inspired super-effective long-
lasting artificial reefs already exist. Some were planted off Ft.
Lauderdale, Florida more than 25 years ago. Bob Wicklund and I
described them in a paper in 1989, (Shinn, E.A., Wicklund, R., 1989
Observations on deep water artificial fishing reefs from Research
Submersible, Bull Mar Sci. V, 44 (2) p. 1041-1050.). What were they?
Obsolete oil rigs brought at great expense all the way from the Gulf
of Mexico by Tenneco Oil Company. For some reason they did not
generate a lot of publicity but then the coral-list did not exist
yet. Must say we observed plenty of divers and fish on them when we
conducted our study. As near as we could tell the fish and encrusting
organisms did not seem to realize they were not true coral reefs.
No, they were not intended to stimulate coral growth but the coral
species that incrusted them and the fish they harbored seemed happy.
Ok somebody say it just made it easier for divers to spear fish. I
won't deny that. One, however, was placed at a depth too deep for
divers.
Now there are about 4,000 of them in the northern Gulf of Mexico
in various depths of water and they are loaded with fish from the
surface to the bottom. They did not cost the tax payers anything.
They were not put there to mimic coral reefs and reefs do not grow
over most of that area anyway. Nevertheless, they host more reef fish
per unit area than any true coral reef I have ever seen. It has even
been proposed that they be incorporated as marine sanctuaries
because in addition to being fish havens they also preserve shrimp
and by catch. Shrimper's don't go there anymore because of the rigs
and pipelines. Gene
