Brad, I've attempted to feed my trout in the small open hole of water each winter. Nothing doing. I haven't seen a fish in the winter in the open water, haven't witnessed a swirl at a pellet or insect. My tiger trout probably feed subsurface throughout the winter, as they are sleek and well shaped when they first appear again in the spring.

I'm not at all concerned about their apparent lack of interest in fish food during the winter months.
