Skip to comments.Well, Great Lakes, It Was Nice Knowing You. Asian Carp Have Arrived.

Ever since Asian carp were accidentally introduced into U.S. rivers in the 1970s, the invasive fish have been hungrily making their way to the Great Lakes, causing residents of the watershed to dread the arrival of carp in delicate Lake ecosystems, and their potential impacts on the 7 billion dollar fishing industry that represents a major economic driver for the region.
Now, a new study suggests that Asian carp have breached southern Lake Michigan, although they have not yet arrived in numbers great enough to devastate native ecosystems.
Scientists at Notre Dame University, Southern Michigan University, and The Nature Conservancy spent two years searching for Asian carp by examining genetic material in the Lake and attempting to match DNA samples to two particularly damaging species of Asian carp, silver and bighead carp.
Out of 2,800 water samples, they found 58 positive links to bighead and silver carp in the Chicago Area Waterway System, which flows directly into Lake Michigan, along with six in western Lake Erie.
Questions remain about how many carp are already in the ecosystemand how long it will take until the fish begin showing up in numbers large enough to cause serious harm.
The most plausible explanation is still that there are some carp out there, lead author Christopher Jerde of the University of Notre Dame told the AP. We can be cautiously optimistic that were not at the point where theyll start reproducing, spreading further and doing serious damage.
Our river fisheries are important but not valued in the billions of dollars, Chapman told TakePart. Whereas the Great Lakes fisheries are hugely economically important. If you cause any perturbations in fisheries like Lake Eeries walleye and yellow perch fisheries, that could be hugely problematic.

Asian Carp Regional Coordinating Committee
"As we begin 2013, I think it's important to note that the Asian Carp Regional Coordinating Committee (ACRCC) made significant progress in 2012 along a number of fronts in our efforts to prevent Asian carp from reaching the Great Lakes. For example, the electrical dispersal barriers are now operating at optimal parameters; no new live Asian carp have been found in the CAWS above the electric dispersal barriers, with over 40,000 hours of netting, electrofishing, and keen observation by experienced fisheries biologists; and we're making advances on efforts to identify technologies to control or eradicate Asian carp."
Zebra mussel, that, I don't have a recipe for.
They cleaned up Lake Erie by filtering its foul waters and they have a native species ... the Lakes Sheephead ... that loves them so much they have multiplied enough to restart a commercial fishery for them in the lake. Other species eat them, too. But the sheephead LOVES'em and is pretty tasty itself.
Running that Helen Thomas photo was uncalled for on a Zebra Mussel thread.
BTW, I heard that zebra mussels themselves are edible by humans, in contrast ... O never mind.
****Ever since Asian carp were accidentally introduced into U.S. rivers in the 1970s, the invasive fish****
Invasive fish? If I remember correctly the European carp was introduced in the 1800s by the US government.
The Asian grass carp was introduced on purpose in the 1970s to clean up waterways and ponds clogged with moss.
I wonder how well that carp will do once those big Northern Pikes get at them. Not many Pikes in the rivers, but plenty in the lakes if I recall correctly.
Thats true. I know a man who paid top $$s for two of them to clean out his 'decorative' pond. It was a pretty fancy affair with lights and landscaping that became overgrown with grasses. The fish cleaned it up in one summer and kept it (returned it) to its intended beauty.
He brought them inside each winter to keep them from freezing up.
There is a canal within walking distance of my house and I sometimes fish for them there. They bite readily on white bread pinched onto a number 6 hook. They get huge and put up a great fight. I pull them up out of the canal, step on them so I can retrieve the hook, then kick them back in. I would eat them except that they are so disgusting and they grow a coating of slime that really stinks. That's why I handle them the way I do.
This guy caught a good one:
Good control tactic is eating them. I hear they are quite good when smoked . . .
When I was a kid it was illegal to throw any carp back into Lake Michigan because they ate bass eggs...opposite of catch and release....catch and toss to the raccoons. Not sure if they still have that law.
Is that ‘shopped or do those fish have people teeth?
My personal opinion is we should be allowed to shoot them out of boats with shotguns.
That’s a Saltwater Sheep’s-head. That one is a female from the color. They’re supposed to be tasty....some claim they taste like lobster, although I don’t.
“Southern Michigan University”
No such thing. Although this is the nickname of the penitentiary in Jackson.
>> I knew about Asian carp. My wife carps all the time, but she’s not Asian.
But does she comprain or the time?
No such place that I know of in the USA.
There is a Notre Dame de Namur University in Silicon Valley. There is a Notre Dame of Maryland University in Baltimore. There is one in Lebanon. And another in Mindanao.
But there is a University of Notre Dame in Indiana.
I always worry about articles that start of with a mistake in the first few sentences. Kind of like calling the University of Texas by the name 'Texas University.'
How about "uninvited lake inhabitant?"
Based on your post #17 and my #19, I think Alison Fairbrother needs to work on “attention to details.”
Two fictitious schools in one paragraph.
As small fry, they're going to be a great food source for the walleye, lake trout, salmon and bass too........
Gotta use steel shot, the lead shot pollutes the lakes........LOL!
Got anything for Cicadas?
It is liquid and smells like grandma before she showers but you get used to it.
It feeds soil microbes that tend to the roots and helps break down the fertilizers into usable forms for the plants.
The Illegal Invasion Continues!
The Great Lakes are also subject to massive algae blooms that destroy oxygen needed by all fish.
The asian carp are a CLEAR AND PRESENT DANGER to the fish populations in the Great Lakes, and every effort should be made to eradicate these destructive fish.
No photoshop, those are real Sheepshead teeth.
“My personal opinion is we should be allowed to shoot them out of boats with shotguns.”
Sporting Carps. :-)
“I find the phrase “invasive species” racist, “specist,” and judgmental.”
May I suggest, “Undocumented carp”?
Its certainly not funny if you make your living off the great lakes sportfishing industry which is worth between 7 and 10 billion per year in Michigan alone.
It would have been so much easier to just shut down the Chicago sewage canal but Obama stepped in on behalf of his Chicago buddies (plus appointed 2 separate czars to not deal with the same issue)
Never heard that. Just called it “Cooper Street.”
I wouldn’t say goodbye to the great lakes exactly but its going to cost taxpayers millions per year to control the carp like it does to control the sea lampreys.
Asian(silver) carp are a problem but I have a question. Where the Hellis Southern Michigan University? I’ve never heard of that. Northern, Central, and Eastern, yes.
A bit tangential, but note how the recovery of the "dead" Lake Erie is taken for granted by this statement. In the 1970's environmental wackoes were saying that the only fish left were weird mutants who could live on toxic waste. So much for "science" liberal style.
That’s about as creepy as it gets.
I think the author may have meant Southern Illinois University - Carbondale, but don’t quote me. They were awarded a 1.1 million dollar contract from the state to study the problem and any benefits derived from the fish.
“I find the phrase “invasive species” racist, “specist,” and judgmental.”
That’s right...there just here for a better life, and to feed their families.
I never thought that they tasted like lobster either>>>>>
Actually they are a type of porgy with worldwide distribution.....so a grouper taste is most likely.
The West Coast Sheep’s-head male is colored differently than the East Coast Sheep’s Head/Prison-fish, being a dark blue/purple color overall with only one vertical white strip....the female looks the same as the picture in the original post.....and the same as the East coast variety.
Is that similar to worry about responses that drop a letter?
Yes, but much more serious since they dropped two whole universities due to lack of thorough research while I dropped one whole letter due to pore proofreeding.
