I have to disagree with you Rex. I put Coppernose in last year. This was the worst winter in my lifetime with 14 below one morning. I caught several CNBG off the spawning beds last week. If they survived this last winter then they should do just fine. Of course everybodys ponds are different. The pond mine are in is 15 ft deep and it rarely ices over so maybe that makes a difference. Also, there has been a guy on Craiglist just south of Mt Vernon that has been advertising small Coppernose out of his pond.
Lifeisgood,where are you located?
