Why is it better to fish with bugs than with foam in winter?

In winter, the temperature is low and the fish are not very active. In fact, earthworms and red worms are better than foam. Red worms are better. Red worms have a strong smell and can attract fish to feed. This is all learned in the fishing capital forum, which is the experience of experts.

There is a fishing proverb: "Earthworms are used in spring, noodles in summer, and red worms are the first choice in winter." The word "first choice" shows the important position of red worms in winter fishing. The winter fishing mentioned here includes surface fishing after winter, ice fishing after freezing, and surface fishing after thawing in early spring, that is, fishing in low temperature season mentioned above. In Northeast China, red worms are used to catch fish such as crucian carp from the end of 10 to May 1 the following year. It was not until the temperature rose in early May that small fish became more active and began to make trouble with hooks before switching to commercial bait fishing.

The answer is difficult, I hope to adopt it.
