Federal and state wildlife officials working in conjunction with academic researchers recently announced six water samples taken from Sandusky and north Maumee bays tested positive for the presence of Asian carp environmental DNA in Michigan and Ohio waters.
The positive samples were among 417 taken from Lake Erie in August 2011, and more than 2,000 samples taken from the Great Lakes Basin since 2010. The Lake Erie batch was recently analyzed and test results were confirmed by eDNA researchers last week. The six positive samples represent less than 1.5 percent of the Lake Erie samples.
Four samples from Sandusky Bay, in Ohio waters, tested positive for bighead carp eDNA, while two samples from north Maumee Bay, in Michigan waters, were positive for silver carp eDNA.
In response to these findings, electro-shocking and netting began Friday in Sandusky Bay with no evidence of Asian carp found. However, additional testing and monitoring are planned by the Ohio and Michigan Departments of Natural Resources in conjunction with partner agencies.
