Study: Asian Carp Already in the Great Lakes

By Chad Love

A new study suggests that Asian carp, the bane of pretty much everyone and the one species we all hope never makes it to the Great Lakes, is in fact already there.

From this story on moneynews.com:
The aggressive Asian carp has reached the Great Lakes despite a government attempt to keep them out, according to a scientific report released Thursday. Researchers now believe the destructive species, which has been steadily moving northward for about 40 years, are now in southern Lake Michigan, putting at risk a sensitive ecosystems and a $7 billion fishing industry. The adaptable foreign fish outcompetes native fish species for food and habitat. "The most plausible explanation is still that there are some carp out there," Christopher Jerde of the University of Notre Dame, the report's lead author, told The Associated Press. "We can be cautiously optimistic . . . that we’re not at the point where they’ll start reproducing, spreading further and doing serious damage."

According to the story, the two-year study searched the Great Lakes basin for Asian carp and researchers say they found DNA evidence for Asian carp being present in southern Lake Michigan, with 58 positive hits for bighead or silver carp in the Chicago Area Waterway System that links directly to Lake Michigan.

Well I can't say that I'm surprised. Can you?

If the actual carp are in Lake Michigan what would make anyone think they won't reproduce. "Cautiously optomistic..." what a bunch of baloney!

They should have killed them all in the canal by Chicago when they had the chance. What a screw up.

Studies show they have been in the Great Lakes for years...

the theory is DSM that these carp only reproduce in rivers- they aren't naturally lake fish and may be able to live their lives in the Great Lakes but not be able to reproduce- that's the optimistic thinking at this time....

This is just disappointing as hell.
Army corps of engineers have been "studying" the problem for years.
So now were stuck with hoping the damn things won't reproduce in a lake environment...great.

Won't reproduce in a lake environment??? I can't believe these so called experts are so stupid!!!! Lake Michigan is fed by rivers that the salmon, who don't spawn in lakes either, swim up stream to reproduce in. I am now less intelligent for having to be exposed to our so called experts spewing this kind of rhetoric!

The Ohio State University has a very detailed study of Asian carp in the Great Lakes. There is a lot of information floating around which is simply not true.

What government attempt to keep them out??!! Hopes and Wishes?? They petition the army corps of engineers and were told "No!" So then what apologies when it's too late? Going to poison the lakes where everyone gets their drinking water?

That study essentially says "we told you so, you're not too late to do something about it, now please help us" bet it falls on deaf ears. If I had business in Great Lakes Aquaculture or Sport Fishing I would sue the businesses, that own/use that Chicago canal. $7 Million for $7 Billion is a no brainer to everyone except politicians and bureaucrats.

One of Obama's pet projects, protect Chicago business at the expense of the rest of the great lakes!!

As per usual...it's all about the big money and this is why the canal system still remains open to let this Asian plague into the Great Lakes.

I guess that means our President's 'Carp Czar' should be fired?
