The next step for researchers is figuring out how to stop grass carp from gaining a foothold.
The calls are growing after a live Asian carp was discovered last week in a Chicago waterway about 9 miles from Lake Michigan.
Some Asian species pose a threat to the Great Lakes.
Invasive fish has been found in Lakes Erie, Michigan and Ontario, although it's uncertain how many there are or how widely they have spread.

A new study published in the Journal of Conservation Biology reports the combined conclusion of a panel of U.S. and Canadian fisheries experts that bighead and silver carp would have little negative effect on Lake Erie perch and walleye
Searchers looking for bighead and silver carp in the Muskingum River didn’t turn up any of the invasive species, the Ohio DNR reports.
