1) POISON THEM
The United States Geological Survey (USGS) is developing poisonous microparticles designed to kill Asian carp exclusively. The idea is to put the poison in a package that only these carp can digest thoroughly enough to absorb a lethal dose. Researchers examined Mississippi River basin fish and found that Asian carp have more of the digestive enzyme trypsin. So they mixed a poison with compounds that only trypsin can break down. This spring, they plan to test the particles on Asian carp in the lab.
2) SHOOT THEM
Silver carp, a type of Asian carp, can leap 10 feet out of water. They have been known to land in passing boats, breaking the bones of people onboard. During the summer, several charter-boat companies on the Illinois River offer "extreme aerial bowfishing": a chance to blindly shoot the jumping fish with bows and arrows.
3) EAT THEM
The Asian carp's anatomy makes it especially difficult to debone, but at least one Chicago restaurant has featured wild-caught Asian carp (which tastes similar to tilapia) on its menu. Its flaky, white meat is low in fat and mercury but high in nutritious omega-3 fatty acids. Fillets of the fish cost up to $15 a pound.
4) TRAP THEM
Biologists at the USGS are developing tasty baits to lure Asian carp to locations where they could be easily captured en masse. So far, tests using common products from health food stores have been successful in the lab, and researchers are gearing up to try their carp-attracting "spirulina smoothie" in Missouri this spring.
5) BLOCK THEM
In 2002, the U.S. Army Corps of Engineers installed the first of three electric fences in the Chicago Sanitary and Ship Canal to stop Asian carp from entering the Great Lakes from the Mississippi River basin. But power issues have knocked the $30-million fences offline several times, and in 2009, researchers found evidence of Asian carp DNA in waters beyond the barrier. The Corps is currently researching other ways to keep the fish out, such as physically separating the canal using a huge mound of soil.

While we're listing items that may or may not actually have any effect, you forgot:
-BURN THEM ALIVE.
Well I think the obvious solution here would be to drowned them.
Didn't Obama shoot down some proposals to keep them out of the great lakes?
Import grizzly bears, or polar bears to eat them.
If the fish are too difficult to debone, grind them up for cat food, or fish food, of course you have to catch them first.
Autonomous robot submarines could catch them, but would require energy to run.
Fillets are $15/pound! Let the fishing industry at them!
So now the problem is that there is too much food that doesnt die out? -_-
Poison - no thanks, you will have poisoned dead fish everywhere that wildlife and unsuspecting people will eat.
Fences etc - expensive and messy, damage ecosystem aswell.
Catch them - with nets and boats in large amounts.
Processign for food is hard for humans due to bones - so ground up fish is the way to go. As a animal feed, pet feed, compost, biofuel or mostly cleaned and deboned fish mass for "cheap end" food for people (since most cheap products include animal bones anyways already).
And PS!... they boke peoples bones????????????????????????????????????
upto I saw the receipt for $7978, I didn't believe ...that...my father in law woz actualie bringing home money in there spare time online.. there aunt has been doing this less than 6 months and just repayed the morgage on there condo and got themselves a Alfa Romeo. I went here, ,, http://www.daz7.com/
Too much fish? lol
Excuse me, what planet is this?
I wonder if these fish were ground up and squeezed, they could be a new fuel source and the rest used as chicken feed or fertilizer ... hmm?
It is amazing what a bunch of whiners we have become.
Finally there is a fish which thrives, is good for you, and we want to get rid of it. How does that make any sense?
Just figure out a dozen different ways to cook them and be glad about it.
"We Entertain When It Rains"
Feed them to homeless people.... its win-win
At least the "whiners" aren't ignorant. The problem isn't an abundance of these fish. It is that they are endangering native fish by out competing them.
Evasive species are bad for the enviroment!
We commentors have gotten way way off track....lol.
Use the tried and true method.
That method has almost wiped out many species. And paying a few cents per pound would be a lot cheaper then all these other proposals. Then grind them up for fertilizer or what ever.
It seems like the obvious answer is a cat food generating robot ship that patrols the water until the numbers fall below ROI, then move on to more fertile waters - What self-respecting feline can resist stinky fish?.
1) Remove all legal size limits and fishing seasons - done I think.
2) Build a one-way net/vacuum scoop type deal allows a fish to jump up through it, then prevents them from falling back into the water - Then vacuum and gravity funnel the stinky slime rockets into a hopper that runs them through a wood chipper.
3) Cook them in a continuous linear vat - a soup of minced blood guts bone and flesh go into one end of a heated pipe, and by the time they get to the other end of the pipe it is fully cooked cat food ready to can.
4) The fully cooked muck is squirted into "Potted Meat" style cans with one-way vacuum seals, heated, and cooled to form a vacuum.
5) A robot tug hauls away the precious load to awaiting trucks at river ports.
6) Half of the cans are labeled as gourmet cat food, and the other half are given a coating of golden lacquer and labeled as a gourmet spread for high-end appetizers at celebrity parties.
