There are no carp where the Yellow River is fast and the sediment concentration is high. In places with slow water flow, a large number of aquatic plants grow, which not only provide excellent shelter for the Yellow River carp, but also provide them with high-quality food sources. The surface of the Yellow River water looks dirty. In fact, the sediment contains a lot of nutrients needed for carp growth, such as calcium, phosphorus and other trace elements, which is also the reason why the Yellow River carp is tender and delicious. Wild carp live in natural waters such as the Yellow River, which has a wide range of activities, large foraging space, frequent swimming and quick response because of its slender body. Most of the cultured fish live in artificial ponds or cages in reservoirs, rivers and lakes, with small range of activities, slow swimming speed and slow response. Because of eating feed, its growth speed is accelerated, the adult fish cycle is shortened and its body is fatter.

Another feature of the Yellow River carp is that it often rushes in the water for food. Tentacles are important organs for it to find food, so they are very developed, and the tentacles are long and thick. And farmed fish don't have to look for food everywhere. The beard is thin and small, hanging on both sides, like the eyes of a blind man. The quantity is relatively small. As for how little it is, the Yellow River carp has become a protective fish. Since the quantity is relatively small, the price is naturally higher. After all, things are rare since ancient times.

A large number of trace elements contained in sediments are exactly the elements needed for carp growth. Although there is a lot of sediment in the Yellow River, it is precisely because of this environment that such a fat carp can be raised, which is different from ordinary wild fish. Sediment contains a lot of trace elements such as calcium and phosphorus, which are the nutrients that fish depend on for survival, resulting in tender meat, delicious taste and less fishy smell of the Yellow River carp. Unlike humans, fish breathe through gills, so this little sediment has no effect on them, nor does it say that it blocks the respiratory tract. Moreover, carp swallowing appropriate sediment can also help them digest food and promote it.
