Now that "voracious," "prolific" and "ugly" Asian carp (yes! Asian!) are on the threshold of the Great Lakes, the propaganda against alien species is calling attention to how little we really understand exotic species and their place in ecosystems. With exceptions, they are not nearly as disastrous as some environmentalists make them out to be. The catches of the day are the closely related silver and bighead carp. Natives of China, they grow to nearly 100 pounds. With eyes low on their heads, they look like they swim upside down. Silver carp have the impressive ability to leap into boats, sometimes knocking occupants silly.

Lindsay Chadderton used this perfect analogy for eDNA sampling for Asian carp around Chicago waterways: "It is like cars driving along a gravel road and throwing up a dust cloud. We are sampling the dust cloud."
The latest find in the dust cloud is not good. Word came Tuesday of silver carp eDNA found past the O'Brien Lock and out to Calumet Harbor.
"We think fish have probably got into (Lake Michigan)," he said.
The formal announcement of that find came just hours after the Supreme Court denied the injunction requested by Michigan to shut the Chicago-area locks to prevent the advance of Asian carp into the Great Lakes.
Let me backtrack. The early release of the results of eDNA sampling (before peer review) profoundly troubled me.
It felt as if the eDNA information in the fall was quickly released to rush the public to judgment - the bludgeon to justify the Great Fish Kill, the poisoning of a 6-mile stretch of the Sanitary & Ship Canal in early December so routine maintenance could be done safely on the electric fish barrier at Romeoville. For that $3 million exercise, one bighead carp was killed.
All in all, it was like another piece in the tale of the greatest boondoggle in Chicago outdoors, the electric barrier.

The Obama administration agreed Thursday to hold a summit of Midwestern governors on keeping voracious Asian carp out of the Great Lakes.
Officials in most of the states that share the lakes and the Canadian province of Ontario want to close two locks in the Chicago River, keeping the carp out but causing problems for shipping. Illinois and the federal government
oppose the plan.

U.S. Rep. Dave Camp (R-MI), the Ranking Member of the Ways and Means Committee, today introduced legislation to immediately halt the potential entry of Asian Carp into the Great Lakes and construct permanent barriers to this invasive species.
Camp introduced H.R. 4472, the CARP ACT, Close All Routes and Prevent Asian Carp Today, which seeks to achieve similar results as the motion filed before the U.S. Supreme Court by Michigan Attorney General Mike Cox. The Court announced yesterday they would not issue a temporary injunction in that case, thus leaving open pathways through which Asian Carp could enter the Great Lakes.

Call it "CSI: Lake Michigan."
Forensic testing of Chicago's shipping channels have spawned new fears Asian carp are invading the Great Lakes.
But scientists say the DNA evidence gleaned from the tests also may be the early warning they need to stop the voracious fish from staging a full-scale takeover in the Great Lakes.
Other samples collected in the past eight months found Asian carp DNA throughout the network of manmade channels and re-routed streams that link the Illinois River and Lake Michigan.
