TRAVERSE CITY, Mich. -- Scientists have begun searching two of western Lake Erie's bays and tributary rivers for signs of dreaded Asian carp.
Officials announced last month that DNA from bighead and silver carp had been detected in Lake Erie water samples taken a year ago.
They said the six positive hits among more than 400 samples they examined didn't necessarily mean the invasive fish have established a population in the lake. Natural resource departments in Michigan and Ohio are teaming with the U.S. Fish and Wildlife Service to take a closer look.
Crews are collecting water this week in the Sandusky River and Bay and the Maumee River and Bay, in the same areas where the positive samples were taken in 2011.
Next week, they will use electroshocking and netting to catch fish.
