I am almost positive they survive, we see them all winter long, plus they must survive, only ones we ever see are probally 1 to 2lbs. No idea what type, for all i know they could be in there for 50 years.
I am in the Tampa area.
I have to beleive the pond has been steadly getting worse for the last 8 years or so. From what I can tell, your looking at an unfished 2.5 acre pond for 8 or maybe more years. I have lived beside it for 2 years now.
