Silver carp prefers sour bait, and can make its own bait when fishing. Corn flour can be used when making silver carp bait. First, prepare a proper amount of corn flour, then pour it into cold water to knead it, knead it one by one, and then steam it in a pot. After steaming, put it aside, and when it is not hot, you can break the steamed corn-bread into small pieces, knead it into powder, and seal it in a plastic bag while it is hot. When sealing, you need to clean the air in the plastic bag to avoid the deterioration of the steamed corn-bread inside. When ready, put the steamed corn-bread in the sun for about 3 days, so that they will become sour food. In addition to sour bait, they also like some stinky bait. They can put the bait left after each fishing together and expose it to the sun. If it is sealed tightly enough, it can be used for a long time.

Silver carp and bighead carp also prefer sour bait, but they are not very interested in sour taste. White flour can be used to make bait for them, and warm water is needed when mixing flour. After mixing flour, wait for natural fermentation. When the sour taste is strong, they can be steamed in a pot. After steaming, it can be mashed with soft white sugar, stirred evenly, and then added with some basic bait.
