The Black carp, one of four invasive species of carp in North America, has made it into the Mississippi River basin.
A new multi-year report from the U.S. Geological Survey (USGS) found the range of Black carp in the Mississippi River basin now includes the entirety of the Mississippi River between New Orleans and the southeastern edge of Iowa, near Keokuk.
The Black carp is a large species of fish endemic to parts of east Asia, typically growing over three feet long and weighing over 100 pounds. The fish was deliberately brought to the states during the 1970s as a means of pest control for aquatic snails in fish ponds. The population quickly grew out of control.
