Winter time can be the hardest time of the year to catch carp.
Not so many years ago it was thought that carp were almost uncatchable during the colder months. I have found through my own and friends experience that carp tend to feed for only short periods of time . Sometimes these feeding periods are quite distinct in the same way as dawn and dusk are good in the summer on a lot of waters. Just like in summer , every water has its own feeding times so its difficult for me to estimate feeding times. I do know of one water in England that fished well in winter one hour after dark so there are no hard and fast rules on this .
