The Quagga mussel (Dreissena rostriformis bugensis) is native to the Dneiper River drainage of Ukraine and is thought to have arrived in the U.S. in ballast water from a cargo ship in 1986. The Quagga mussel alters the food web by filtering water and removing plankton which reduces food for native populations of alewives, salmon, whitefish and native mussel species. The mussels also ruin beaches and attach to boats, water intake pipes. They promote water clarity by filter feeding which allows sunlight to penetrate to the lake bottom, creating ideal conditions for dangerous algae blooms.
