Hi Fatih,

I'm not a pro but I think there is a big difference between just surviving and actually thriving. Southern strain fish have the advantage of a longer growing season than the Northern varieties. If you put a Florida LMB up North, and it managed to survive, I would think the cold stress and short growing season could actually make it underperform when compared to a Northern.

Again, I'm not a pro...just my 1 cent
