BG and LMB and most all fish metabolism slows to a crawl in cold temps as they are cold blooded. They do feed to different degrees in cold water just not much for BG and LMB. So no big reason for a feeding program if they won't eat much and all you get is nutrient bulid-up from uneaten feed. Plus the cost is a factor.

Scott my comment about feeding moist pellets through the ice was about warm and cool water fish (BG ,LMB , HSB , YP and Catfish)not about cold water fish like trout. They live in cold water and eat fine.
