The stocking rates required to achieve control of macrophyte populations obviously will vary with hybrid size and age, plant species, plant productivity, and water temperature. Diploid and triploid grass carp had similar standardized energy balances: 12–13% of the energy ingested was used in metabolism, 74% was egested or excreted, and 13–14% went into growth. Some carp fishing in France lakes stock a small amount of young grass carp to keep the weed under control and they act as effective house-keeping.

Abstract Grass carp Ctenopharyngodon idella and genetic derivatives are widely used as biological control agents for aquatic macrophytes.
