Introduced species

Numerous introduced species are found in the Mississippi and some of these are invasive. Among the introductions are fish such as Asian carp, including the silver carp that have become infamous for out-competing native fish and their potentially dangerous jumping behavior. They have spread throughout much of the basin, even approaching (but not yet invading) the Great Lakes. The Minnesota Department of Natural Resources has designated much of the Mississippi River in the state as infested waters by the exotic species zebra mussels and Eurasian watermilfoil.
