Crews find 20 new positive eDNA hits for Asian carp in Lake Erie

There’s new evidence that Asian carp could be in western Lake Erie.

Last month, crews took 150 water samples from Sandusky Bay and the Sandusky River.  They were testing for traces of genetic material from Asian carp. The results just came back this week.  20 of those samples tested positive for the presence of silver carp.

Now, these positive samples could indicate there are live carp in the lake.  But biologists say the genetic material could’ve also come from dead carp, or fish-eating birds or boats that came into contact with Asian carp.

Electrofishing survey finds no silver, bighead carp in Lake Erie

Don't worry, fish, I'm not gonna eat you. Fish temporarily stunned via electrofishing.

Silver and bighead carp don't appear to be living and breeding in Lake Erie - yet.

Environmental DNA from the fish was found in the lake near the Maumee River last year.  Environmental DNA comes from things like fish mucus, excrement, or scales.

But no Asian carp were captured in a recent electrofishing survey, which temporarily stuns fish with an electrical current.

Todd Kalisch is with the Michigan Department of Natural Resources.

Latest search fails to find Asian Carp in Illinois lake which is a short distance from Lake Michigan

Another search of a lake close to Lake Michigan has failed to find Asian Carp. The invasive carp could threaten native Great Lakes fish populations.

Fishermen spent three days last week sweeping a six mile stretch around Lake Calumet, near Chicago. The result: 6,300 fish caught, 30 different species, but no Bighead or Silver carp.

It’s the second time this year that teams led by the U.S. Department of Fish and Wildlife, the Army Corps of Engineers, the Illinois Department of Natural Resources and other agencies, have scoured the waterway looking for Asian carp.
