I take it the fish are very small? They can still be fed in the pond until the temperature drops to below 10c. If they are small fish, flakes or small pieces would be better for them. They get fed once a day.
Down here hubby has a koi pond and he feed all year as its never that cold !! if they stop coming to the top we dont feed and will start the wheatgerm food in a few weeks, we found not feeding all winter caused big problems in the spring with 'bunged up' fish :-\Slugs and snails are greatly recieved by our lot but they are huge and we have a 3ft catfish in there to clean the bottom up of any missed food.Go by the fish, if they are up the top asking for food feed them :)
