In the winter, the metabolism of carp and other fish decreases. Rather than gorging themselves at every opportunity as they do in the summer, winter carp only eat what they need to survive. They often move to different parts of the lake and can be difficult to predict in winter, making it even harder to land a carp. Experimenting with a variety of baits well-suited for winter is crucial if you want to increase your odds of a good catch.
In the summer, carp are attracted to large bait beds and will eat ravenously. In the winter, however, carp are very selective nibblers and only bite at baits that really catch their interest. The AnglersNet website recommends using glugged boilies, which are boiled dough bait soaked in a liquid attractant, to catch the attention of selective winter carp. Bright colors can also catch the attention of carp in the winter, so use a brightly colored glugged boilie to increase your chances of catching your quarry.
