Invasive species is hurting native fish population - News8000.com - WKBT

TRAVERSE CITY, Mich. (AP) - Anglers aren't reeling in prized fish the way they used to.

That's because parts of the Upper Mississippi River have seen a significant decline of sport fish due to an invasive fish. 

A new study in the journal 'Biological Invasions' found Asian Carp are out-competing native fish like yellow perch, blue gill, and black and white crappie. 

In the late 1960's four varieties of Asian carp were introduced to the region to clear sewage ponds and fish farms, but they escaped into the mighty  Mississippi.

For more than two decades the U.S. Army Corps of Engineers has monitored the fish in the river collecting samples and developing restoration plans.
