Is fishing crucian carp off the bottom or undercover?

Many friends will like to fish crucian carp, but they don't know much about crucian carp, such as whether it is fishing from the bottom or lying down. Fishing for crucian carp is generally from the bottom, and the water depth can be from the bottom. You can only lie at the bottom when the water is about one meter shallow. The life habit of crucian carp is in the upper part of the water, so you should be higher. In winter, the temperature difference between the upper and lower water layers will be obvious. At this time, crucian carp generally float by temperature in droves. In winter, deep water (about 4m) leaves the bottom from 10 in the morning to 15 in the afternoon, and then lies on the bottom after 15 in the afternoon. If there are fish bubbles, there are still no fish lying on the bottom of the water. At this time, the fishing will drift. Off-bottom fishing is also a kind of fish drift. Don't float too high, just 1-5 cm from the bottom.
