Model bait, also known as molded bait, first appeared in bomb hooks. Because the preparation of bomb bait requires different ingredients, some people molded the bait prepared in different proportions and made into a fixed bait with the same shape, casting and throwing, and turning into powdered bait 3 to 5 minutes after sinking into the bottom.

In the early days, baits were used for bomb hooks instead of bad food baits, but now they have changed. The bottom nest material, bomb hook bait, grape hook bait, bait for bait fishing, bait for bait fishing, bran cake hook, bean cake hook, and flying hook can all be used. There are currently three types of fixed baits, square bottom nest material, cylindrical explosive bait and square multi-layer flip bait. Square bottom nest material is also known as “multi-layer mooncake bait”. The upper layer expands and loosely, and the main lure is: the lower layer is tight, the softens slowly, and the main fishing is. When the hand-removing bait is inaccurate, it becomes scattered and floats away from the fishing point, the compressed square bottom material is directly put into the fishing point. The nest is relatively concentrated, and you can also divide it into four and then concentrate it on one point.

It has three characteristics: tightening, layered softening, and long duration. The cylindrical explosive bait changes the disadvantage of loose food bait and requiring force and repeated squeezing to form a ball. It has the characteristics of fast bait, throwing it will not fall off, and sinking the bottom and fluffy and swelling. The multi-layer flip-flop bait is a three-layer square bait with holes in the middle. After sinking to the bottom, the upper layer dissolves first, and then the middle layer softens. After 7 to 9 minutes, the lower layer begins to soften, which is usually used as bait. However, the bran cake hooks and bean cake hooks in Hunan are drilled in the middle of small pieces of bran cakes or bean cakes, so that the main rope of the bomb hook passes through the holes and the hook lies around. When the bean cakes soften, they will be sucked into the group hook. The bait is suitable for fishing at the bottom, and is easy to carry due to vacuum packaging, and is very likely to become a new pursuit of modern bait because it is resistant to gnawing, catching and pecking.
