Whether it is good to catch crucian carp on rainy days depends on the temperature and the amount of rain. If it rains in spring or summer, the difficulty of fishing is generally not very high. Because the temperature in spring and summer is warm, even if it rains, the temperature drop will not be obvious, and the difficulty of fishing will not increase. But when it rains in winter and autumn, it is more difficult to catch crucian carp. Because the temperature is low, crucian carp will move into deep water, and its appetite and activity will decrease, so the difficulty of fishing will also increase.

1. Choose bait: When fishing crucian carp in rainy days, choose some bait with strong fishy smell. Earthworms, red worms and so on are common. These baits have great fishy smell and are attractive to crucian carp. If the weather is cold, you can add some small medicines to the bait, so the effect will be better.

2. Choose a suitable position for fishing crucian carp in rainy days, because there is not enough oxygen in the water in rainy days, and the fishing position can be selected as water inlet and tuyere. If there is not much rain, you can fish a little shallower. If the rainfall is heavy, you should choose to fish deeper.

3. Start fishing: After choosing a good position, you can try to throw the rod. Rainy days have a great influence on throwing the rod. When throwing the rod, you need to use appropriate strength, so that the fishing rod can be accurately thrown into a good position. When fishing in rainy days, crucian carp can be attracted by moving up and down, left and right. When crucian carp takes the bait, it is necessary to lift the pole immediately.
