Welcome to the forum, bull.

Fish metabolism, and hence their food requirements, drops way down as water temps drop. LMB metabolism, for example, drops by 1/2 for an 8 degree F temperature drop. So food needs for your fish in Winter are just a few percent at most of what they would be in the Summer.

Pelleted feed has also been indicated as possibly bad for fish in low water temps, perhaps because it takes so long to be digested under these conditions.

In short, no, don't worry about feeding under ice.
