Bing: No offense meant to anyone but yes I do believe some of the warnings were a bit overstated. I believe fish are primarily dormant over the winter and use very little oxygen in 35 degree water. Have you ever left a bucket of Emerald shiners in a garage when the temp is below freezing. The top ices over and as long as you break the ice occassionally those darn things will live for weeks. In the spring they won't survive overnight.
Fish have differing levels of oxygen demand. Larger fish tend to suffer more from low O2. It's hard to extrapolate from shiners to BG or LMB that are 10 or 100 times larger.
There have been several reports of fish kills posted here already so I think a lot of those predictions were correct. Depends on your latitude, pond depth, length of snow cover, amount of vegetation, etc. etc. but I don't recall a single winterkill photo being posted in the previous two winters combined that I've been posting here.
