Since you hand feed, you'll get to observe how much the fish consume as the water temperature drops. Decrease the amount you feed accordingly. "Feed what the fish will consume in 10 minutes" is a good rule of thumb.
In addition to eating less in colder water, their digestion process also slows. I feed smaller pellets when the water gets below 55 deg F, and cut the number of times per week that I feed. Some fish may continue to feed with water in the upper 40's, and you may want to throw a few pellets on warm sunny days in the Winter, for the fun of seeing if any fish show up to eat.
Good info, my main concern is the next day 30-45 day before the water temp gets too cold, currently 72*
These fish are currently cleaning up everything I can throw at an alarming rate
