Ponds in a Warm Winter

We had a cold snap a week or so ago and the entire upper half of the US was hammered with snow, ice, high winds and just horrible weather. Here in New Orleans, we had temperatures in the 20's and that is really unusual.
Up north, ponds froze over, fish were at the bottom of the pond in torpor and we all thought winter was here. Wrong. It is now back to the 50's up north, ponds are no longer frozen and fish are swimming around happily.

The big question is "Do we feed our fish?"

I think not. The temps will drop again soon. It is dicey to feed fish when the temps are below 55 degrees anyway. Their digestive systems slow down and they may well have some problems with food. Any left over food will just stay in the water and decompose, thereby fouling the water.
