Scattered-shot bait is the most mainstream bait for carp fishing in black pits. It mainly uses small yellow flour bait as the basic bait, and adds some auxiliary bait and fishing chemicals to make a relatively dry bait. When it enters the water, it will disperse, creating an atomized area, which plays a role in attracting fish quickly. The general pointer of loose cannon bait is effective for raw carp and when the fish quantity is large. If the amount of fish released is very small, and all of them are returned to the pot, the effect of scattered cannon will be greatly reduced, and even the fish will not be lured, but will be scared away.

Dipping hemp balls into hemp balls is mainly a fishing method for slippery carp in black pits. Beans, hemp balls glue and soft sticky bait are used as bait cores, and then all kinds of small carp baits are dipped, and some are dipped in floating particles. This kind of fishing method can reduce the alertness of slippery carp to bait, and the effect of attracting fish to slippery carp is usually better than other types of bait.

Soft-sticky rub bait Soft-sticky rub bait is a hook bait made of pastry bait, which is rarely used alone. Because of the poor effect of attracting fish, it is usually used with loose cannon or hemp granules. As fishing bait, the taste, size and softness of soft sticky bait are very important. The smoother the fish mouth, the softer the soft sticky bait, the smaller the person and the more comfortable the taste, the higher the biting rate.

In the eyes of many fishermen, the tastes of catching carp are mainly sweet potato, jujube, musk and fruit. However, the more common flavor is used, the more repulsive carp are, and the worse the effect is. Black pit fishing gods usually use compound fragrance. Because all carp like fragrance, the requirement for fragrance is that it smells comfortable, fragrant and non-irritating. Compound flavors that meet these conditions can be used to catch black pit carp.

The eating hobby of cultured carp carp is omnivorous fish, which eats both meat and vegetables. The carp popularized in Heikeng are generally divided into cage culture and pond culture, which are divided by region, and Tianjin and Jiangsu are the most. In the case of aquaculture, fish are generally fed with special bait (such as Tongwei pellet feed), and fish eat zooplankton at the same time.

Feeding bait can be divided into juvenile fish particles, adult fish particles and penghua (floating) particles according to different functions. Its raw materials are diversified, including various cereals (bean cake, corn flour, sweet potato flour, etc.), animal protein (silkworm chrysalis powder, fish meal, etc.) and appropriate additives. Additives also include carbonate, vitamins, adhesives, attractants, drugs, essential amino acids and so on.
