Hundreds of black carp have been reported in the Mississippi River basin, and the invasive fish harm the local ecosystem by threatening important native species.
A study released in December by researchers from Southern Illinois University, the U.S. Geological Survey, the U.S. Fish and Wildlife Service, Missouri State University and the Missouri Department of Conservation found black carp have been established in the Mississippi River basin.
Black carp are native to eastern Asia and were introduced to the U.S. in the 1970s and 1980s in imported, contaminated grass carp stocks shipped to private fish farms, according to the USFWS.
“The use of black carp in these types of aquatic environments is regulated and requires permits, and there isn’t a clear understanding on how black carp escaped those settings,” the December USGS release said.
The USGS maintains an online database of nonindigenous aquatic species, including black carp. The species has been reported in the Mississippi River, as well as Kaskaskia River, Horseshoe Lake, the Illinois River, Ohio River and more.

..."What makes black carp invasive?
Invasive species are non-native life introduced to the environment. They spread and have the potential to harm human health, the environment or the economy, according to USGS.
Black carp compete with indigenous species for resources and pose a direct threat to native mollusks, researcher Kroboth told the News-Democrat.
Nearly 70 freshwater mussels are native to Missouri, and native mussels generally provide water filtration services to the Mississippi River, Kroboth said.
Mussels feed by filtering out particles from the water, and they can also provide a habitat for other species to attach to.
“Mussels support ecosystem health by improving water quality — they filter out bacteria, algae and pollutants as they breathe and feed — and provide food and nutrition for other species,” the USGS release said."...
