[center][size 3]Six Lake Erie water samples test positive for Asian carp eDNA[/size]

Federal and state wildlife officials working in conjunction with academic researchers today 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 this 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.
The findings indicate the presence of genetic material left behind by the species, such as scales, excrement or mucous, but not the establishment of Asian carp in Lake Erie. Positive eDNA tests are regarded by the scientific community as an indicator of the species’ recent presence, however, positive results can occur whether the organism was alive or dead.
While the eDNA findings suggest the possible presence of the invasive species, officials have no physical evidence the fish have migrated to the Great Lakes. Prior to 2003, three individual bighead carp were collected in Lake Erie. No additional observations have been reported during the past decade.
“The results from these water samples are certainly concerning, as this marks the first time Asian carp eDNA has been detected in water samples from Lake Erie, or any of the Michigan waters intensively surveyed for the presence of invasive carp,” said Michigan DNR Fisheries Division Chief Jim Dexter. “Protecting the Great Lakes from the threat of Asian carp is critical to the health of our sport and commercial fisheries and to the quality of life in Michigan. We are actively engaged in Asian carp surveillance programs throughout the Great Lakes, including Lake St. Clair and Lake Erie, and the Department stands ready to take the necessary and appropriate actions to investigate and respond to these test results.”
In response to the positive test results, officials from the Michigan and Ohio DNRs, the Michigan Department of Environmental Quality, the U.S. Fish and Wildlife Service, and White House Council on Environmental Quality are developing a plan of action in collaboration with the eDNA research team to obtain follow-up samples and test results as quickly as possible. Test results from future water samples will dictate the nature of further response methods.
“This lake is Ohio’s greatest resource and our main objective is to keep it healthy,” said Rich Carter, Ohio DNR’s Executive Fish Management and Research Administrator. “The DNA findings have put Ohio fish and wildlife officers on high alert and marshaled our immediate action. In response to these findings, electro-shocking and netting in the identified areas of Sandusky Bay have already been completed and no Asian carp were found. Testing and monitoring will continue and we will work with Michigan and our other management partners to develop a coordinated approach to defining the status of Asian carp in Lake Erie.”
Since 2010, the Michigan DNR, Ohio DNR, USFWS, University of Notre Dame, Central Michigan University and the Nature Conservancy have partnered to collect water samples from Great Lakes basin waters, including the Chicago Area Waterway System, southern Lake Michigan, western Lake Erie and tributary streams of lakes Michigan and Erie. The collaborative early-detection Asian carp surveillance program is funded by the USFWS with a federal Great Lakes Restoration Initiative grant, administered under the Asian Carp Control Strategy Framework.
Asian carp, including bighead and silver carp, pose a significant threat to the Great Lakes ecosystem and economy. Anglers are urged to become familiar with the identification of Asian carp, including both adults and juveniles, as the spread of juvenile Asian carp through the use of live bait buckets has been identified as a potential point of entry into Great Lakes waters.
A video demonstrating how to identify bighead and silver carp can be viewed on the USFWS YouTube channel at [url "http://links.govdelivery.com/track?type=click&enid=ZWFzPTEmbWFpbGluZ2lkPTIwMTIwNzE0LjkwMzU1NTEmbWVzc2FnZWlkPU1EQi1QUkQtQlVMLTIwMTIwNzE0LjkwMzU1NTEmZGF0YWJhc2VpZD0xMDAxJnNlcmlhbD0xNzA3NjczNyZlbWFpbGlkPWxpbmsxOTYxQHZlcml6b24ubmV0JnVzZXJpZD1saW5rMTk2MUB2ZXJpem9uLm5ldCZmbD0mZXh0cmE9TXVsdGl2YXJpYXRlSWQ9JiYm&&&106&&&http://youtu.be/B49OWrCRs38?source=govdelivery"]http://youtu.be/B49OWrCRs38[/url].

I saw on the news this past week, a town in Illinoise was showing how taisty asian carp can be at a asian carp fry festival..
all I can say is they had better put on their feeding bags cuz I dont want to eat them things here.[mad]
