Abstract : During the last decade, research to discover means of controlling obnoxious aquatic plant growth has included evaluation of various species of herbivorous fishes. Two of the species studied, Israeli carp and the white amur fish, have shown sufficient efficacy to offer promise for utilization in controlling aquatic weeds in habitats occupied by established game fish populations. The Israeli carp was only effective in controlling filamentous algae and is useless for control of rooted aquatic plants. The white amur fish, on the other hand, has shown great promise in controlling submersed and emersed types of plants. The purpose of this research report was to determine the efficiency of the white amur fish (Ctenopharyngodon idella) as a biological control agent for aquatic weed populations in natural habitats, with evaluation of the effects of space and plant nutrients resulting from the destruction of weeds in the aquatic ecosystem. This research information provides the basis to establish a system of knowledge for control and operational procedures for use of white amur fish for aquatic plant control. (Author)
