Last week officials in Ohio and Michigan announced they found more evidence of Asian carp in Lake Erie. They didn’t find a carp but numerous water samples tested positive for what’s known as environmental DNA. That suggests Asian carp were in Sandusky Bay this summer. If the exotic fish get into the Great Lakes its expected they’ll further upset the current ecosystem.
For years eDNA tests have found evidence of carp near Lake Michigan, on this side of the electric barrier meant to keep them in the Mississippi River. But the value of these test results is disputed. Peter Payette spoke with Dan Egan, a reporter for the Milwaukee Journal Sentinel about this controversy.
