ABSTRACT

Studies undertaken at Auburn University determines the value of herbivorous fish as biological control agents indicate that the white amur (Ctenopharyngodon idella Val.) has greater potential than other species studied. The environmental benefits derived from use of a biological control agent like the white amur suggest that more definitive and extended research be done to find means to utilize the potential in solving aquatic weed problems that have reached major proportions in some situations. However, most experiments neglected to measure effects of the white amur on other fish species. This must be done if the white amur is to be considered for aquatic weed control in the US This experiment attempted to determine effects of white amur at various stocking rates on channel catfish and striped bass, and aquatic plants: water hyacinth, Spirogyra, and Hydrodictyon.
