Peter J. Mumby, a biologist at the University of Exeter in Britain, said that people have used marine reserves to manage reef fish for many years. Dr. Mumby and colleagues set out to see whether this was so, studying fish populations at a reserve in the Bahamas. He said that this reserve that allowed predators to come back also allowed parrotfish to come back. Dr. Mumby and his colleagues found that parrotfish longer than about six inches were too big for the grouper to eat.
