Carp is a very common fish species in fresh water, which is widely distributed, not only in rich water, but also in thin water. Lean water refers to the waters with less nutrients, and the food in them is not particularly abundant. In such waters, although the number of fish may not be particularly large, there may be some common fish species distributed, and carp is one of them. It is also common to fish carp in thin water, which is often encountered by anglers. Fishing carp in thin water is different from fishing carp in fat water, for example, there are great differences in bait used.

As mentioned above, it is ok to fish carp in thin water, but there is a big difference between fishing carp in thin water and fishing carp in fat water, which is the case from the bait point of view. In lean water, carp's food is limited, and they prefer a lighter flavor. Therefore, the original bait is often used at this time. For example, corn, wheat, rice and commercial bait purchased from shops are all original bait. This flavor is often used when fishing carp in thin water.

In addition, a class of substances that can be used is small medicine, that is, a class of substances with strong taste. Although these substances can be mixed into the original bait, we must pay attention not to overdo it, otherwise it will easily backfire. Specifically, the types that can be used include barley paste, fruit acid, sweet potato paste, etc., which are small medicines with sweet or fruity taste. Carp likes them better and can be mixed into the original bait in proper amount. In addition, state bait also needs to be used in moderation. For example, snow pollen, light bran, etc., these substances regulate the atomization state of bait and are often used.
