Federal and Missouri state wildlife officials have successfully used a new technique to remove the majority of Asian carp from Creve Coeur Lake in St. Louis County. 

Earlier this year, the U.S. Fish and Wildlife Service, Missouri Department of Conservation and St. Louis County Parks and Recreation deployed a method to extract the invasive species from the lake.

Asian carp has invaded many Midwestern lakes and rivers, outcompeting native fish populations and tainting water quality. Traditional netting methods have not been effective, since the fish jump over the nets. Under the "unified method" developed in China, nets and electric barriers create a grid-like system where fish are herded and then removed.
