ABSTRACT
Studies undertaken at Auburn University during the past 10 years to determine the value of herbivorous fish as biological control agents indicate that the white amur (Ctenopharyngodon idella Val.) has greater potential for that purpose than other species studied so far. In these tests, species of Chara, Potomogeton, Eleocharis, and Rhizoclonium have been well controlled. None of the ponds tested became muddy or developed phytoplankton blooms as a result of the feeding activities of the white amur. 1
