Don't waste your money. Numerous studies have been done and the questionable point in the US seems to be the 37th parallel (Mid-TN to OK). North of this line would be highly unlikely to be beneficial. They are genetically suited to warmer climates, and the only chance of anything meaningful would require a heated water system like a Power plant lake. If water temps get below 40 degrees, you're basically toast.

Feel free to check with the DNR as posted already, but I'm guessing you'll get the same or a similar answer.
