Lest we throw out the baby with the bathwater...

Bellwood and Choat (1990) put it nicely:
"The assumption that parrotfishes represent a single group of grazing
herbivores is addressed by morphological, functional and ecological analyses
.. This assumption is rejected . "

Bellwood and Wainwright (2002) have a great set of histograms. Very few
species of scarids (parrotfish) are involved in substantial bioerosion. In
the Caribbean, only 1 of at least 6 species are involved. Only 2 of 15 Great
Barrier Reef System species and only 4 of 10 in the Red Sea are involved. 

Most parrotfish are important algal grazers.

Steve, I know Parrot fish are a delicacy in the Pacific. They are protected
in the Fla Keys and at anytime of day you can watch them biting chunks out
of live coral especially Montastrea sp. Once they are listed we might want
to consider spearing them to protect the coral from" harm." Since it was
discovered that the listed Spotted Owl in old Growth Forests is declining
due to predation by Barred Owls  the Fish and Wild Life Service is shooting
the Barred Owls. If it works for Spotted Owls maybe it will work for
corals...Outrageous eh? Well who knows what the future will bring in the
world of government regulations and unintended consequences. Gene
