triploid carp are herbivores with asian carp are plankton filter feeders so this would do nothing..

Actually Longshot were talking about sterile ones, there are different species of triploid carps. Grass carp is most common species used in creating the triploid carps, but triploid common carps, triploid bighead/silver and even triploid hybrid carps (grass x bighead etc) have created. If the original group of Asian carps were triploid, the infestation will never happened.
KDFWR has reintroduced Gators back into KY waters and rivers, we have river freezes often, not so much the Ohio but smaller creeks, etc. where they were introduced again, they were once native to KY. If they can survive our waters, I see no reason why they couldn't survive the waters in the Great Lakes. Fish are able to adapt to many circumstances, just when we think they can't, they do.
So you are saying that the fish are programmed to survive an extra 1 -3 months of cold weather? Since you know everything about everything on Natives, etc....prove it. I want to see documentation, not what someone said on NANFA or anywhere else you get your information.
Here, I will go first. Look at Merwin Preserve in Illinois, its 3 hours from Chicago, right next to the Great Lakes, they get the same cold weathers, he same duration, of course some years will fluctuate, etc. These Gators are living with no problems whatsoever. This just goes to show what I said above, fish are capable of more than we know.

I didn't have the time to read all the posts so I don't know if this has been posted but back in 2009 Kentucky fish and game introduced gator gar to the Ohio river and it's tributaries so who knows what will happen. If they survived or not. I know they had 14,000 fry that they released at about 12-14" in the ecosystem. Personally being from Indiana I hope they take hold and we have a new game fish to compete for.

Each species of fish has a water temp range it does well in and grows. Each species also has a range of temps (high end and low end) called upper and lower lethal temps that causes stress and if extreme for a sufficient period then death. The longer the cold periods get, the temperature gets lower, the more stress a fish encounters the more likely it dies. There is within in each species some local adaptation over time. It has to do with cellular metabolism and imbalance. You should read up the lethal temperatures, cold tolerance and cold stress on North American fishes sometimes, it's very interesting read on these studies. They also explained why Redear sunfish have hard time to surviving harsh winters and why Florida Bass and their hybrids were not popular in northern regions. Yes fish is very adaptable but that doesn't mean they are super hardy or being super immune to everything.
You have to remember that not all lakes have same temperatures. BTW what is your problem with NANFA?
P.S someone beat you with the link few pages ago. It's only been a year yet and last year's winter was pretty very mild so it's too soon to declared that Alligator gars are capable to survive in harsh winters.

Last year, 1 hour away from Lewiston, IL it was 10 degrees below zero and about another approx. 1 hour away it was 17 degrees below zero at a later date, I'm pretty sure the lakes were frozen at this point. This was also accompanied by a lot of snowfall all around this location, but yet this year the Gator's in this lake were growing. I would say that the next survey should have excellent results.
I'm not sure what "not harsh" is but 10 and 17 degrees below zero, is pretty harsh to me on young fish.

If you read the comments on http://blog.nature.org/science/2013/03/04/big-fish-return-of-the-alligator-gar/ you will see that that the Great Lakes Advisory Boars is interested in stocking the Gators in the Great Lakes.
Will the fisheries biologists Rod Hilsabeck/Trent Thomas or the Illinois Department of Natural Resources be providing the spunky Bottoms Alligator Gar Study findings to the U.S. EPA Great Lakes Advisory Board. This could be pivotal in the development of the new Great Lakes Restoration Initiative (GLRI) Action Plan whos current main focus is the Asian Carp threat to the Great Lakes.
The growth rates are promising for Northern Waters.
