It is not possible to catch grass carp with corn in cold weather, because the appetite and activity of grass carp will be affected by cold weather. Although the sweet taste of corn is attractive to grass carp, when the water temperature is too low, the taste of corn will be slow, and there are not many grass carp that can be attracted.

In addition, grass carp's appetite is not high when the weather is cold, and it may not be very interested in corn, so it is best not to fish grass carp with corn when the weather is cold. Of course, it doesn't mean that corn can't be used after cold weather. You can choose to nest with corn when fishing, so the effect will be better.

It is better to catch grass carp in cold weather with fishy bait, and common red worms, loaches, earthworms, snail meat and clam meat are all suitable. Although grass carp prefer plant bait, in winter, the attraction of plant bait to them is not very strong, and the diffusion speed of plant bait into low-temperature water is not fast, so it is most appropriate to choose fishy bait. If the fishy bait effect is not good, you can try to add some small medicines, which will be more attractive. If you want to nest in advance when fishing, you can choose to soak tender corn with koji wine, which can also attract grass carp.
