Use of antimycin-microparticles and alfalfa to control Grass Carp Ctenopharyngodon idella

Since their introduction in the 1960’s, grass carp (Ctenopharyngodon idella) have spread across the North American continent as far north as the U.S./Canadian border in the Great Lakes. Grass carp are an herbivorous species and can significantly reduce the amount of macrophytes and other plant material in a body of water. Subsequently, this can lead to many detrimental effects for...
