Why don’t fish freeze to death in icy water?

Hmm, interesting. There was a pond in front of the office at Denver which was created when construction diverted some of the Platte river, and it had 3 or 4 fish 'stuck' in it. In the winter the water froze solid and I walked over and saw one of the fish sitting there frozen in the ice. I was tempted to try to chip it out but it was too deep and the ice too hard. About 3 weeks later the ice melted and the fish was swimming around again. It was pretty amazing to see.

Depending on the depth of the pond, it may have not frozen to the bottom - water has the highest density around 4°C (~39°F).

If the pond isn't very deep, and there's no streams or anything else coming into it that would oxygenate the water, usually the fish would die because of that. Happens all the time around here if water levels change drastically (say a beaver dam lets go), followed by a hard, cold winter with deep ice.
