The herbivorous fish Ctenopharyngodon idella (Val.), commonly called the white amur or Chinese grass carp, appears to be the most promising organism presently available for biological control of many submersed aquatic plant problems. The white amur was introduced to the U.S. in 1957. 1 Since that time, the Arkansas Game and Freshwater Fish Commission has released this fish in the natural aquatic ecosystem in an effort to control many of their aquatic plant problems. They have reported no detrimental effect on the natural system by these fish and are confident that the white amur will become a part of their aquatic vegetation management program. 2
