On the other hand, this MAY also support the hypothesis that winter feeding provides very little benefit to certain species of fish, most notably warm water species. Even if they are willing to feed, cold water inhibits or at least depresses digestion, and undigested feed is simply expelled.
This tidbit also came from "Bluegills, Biology and Behavior", by Stephen Spotte.
It also may go along with N8tly's comments in the other thread about there not being a good commercially available feed for winter feeding yet. Maybe the natural food the fish catch digests just fine in cold water, but the artificial food is not of the best composition for cold water digestion. He implied that if a commercial food does come out for cold water feeding, its composition will be considerably different than current feeds.
