What is the best practice for feeding pond fish during winter?

The best practice for feeding pond fish during winter is to gradually reduce feeding as water temperatures drop below fifty degrees Fahrenheit and stop completely once below forty degrees. Fish metabolism slows in cold water and they eat less. Overfeeding leads to uneaten food decay that harms water quality. Switch to wheat germ or low-protein food in fall, and maintain clean, oxygenated water for fish health during dormancy.
