The best water depth for crucian carp fishing is 1-3 meters. Crucian carp does not always stay in a certain water layer, and the surrounding environment has a great influence on its distribution.

The primary influencing factor is temperature. When the temperature is 15-3℃, the activity of crucian carp in foraging and reproduction is high. Generally, it can catch 1-2 meters in shallows. However, when the temperature is too low or too high, the crucian carp will move to a deeper water layer, and it is necessary to fish deeply.

The second is air pressure. If the air pressure is low, the crucian carp will float up and need to be fished shallowly.

It is best to catch crucian carp with light plain bait in warm season from spring to autumn, and it is cold in early spring, late autumn and winter, and it is best to use live bait. Crucian carp is an omnivorous fish, and their feeding habits will change with the change of temperature.

When the temperature is relatively high, crucian carp is obviously more interested in light bait. You can choose corn, wheat, sweet potato and other vegetarian bait, or buy commercial bait directly.

In winter, the activity of crucian carp is reduced, so it is not easy to talk. Only the fishy smell of meat bait can effectively stimulate their appetite and make them talk. Live baits such as earthworm and red worm are the best among the meat baits.
