Silver carp is an important freshwater fish in China, which lives in various water systems and lakes.
Silver carp is quick-tempered and good at jumping. Living in the upper and middle layers of water. It is a typical filter-feeding fish, which mainly feeds on zooplankton such as rotifers, cladocera and copepods in the fry stage. When it grows to more than 1.5 cm, it gradually turns to eating phytoplankton, soybean milk, bean dregs powder and rice bran, and prefers to eat artificial particulate compound feed.
Suitable for aquaculture in rich water. It is also a large fish, which can weigh 30 ~ 40 kilograms in natural rivers. In the low temperature season, the appetite decreases, but they still eat, mostly concentrated in riverbeds and deep lakes for the winter.

Silver carp grows faster than silver carp. Individuals weighing over 10 kg can usually be seen in natural rivers, lakes and other water bodies. Suitable for breeding in fertilizer ponds. With sufficient feed, the weight of 1 year-old fish can reach 0.8 ~ 1 kg.
The age of sexual maturity is the same as or earlier than that of grass carp. Mature individuals are heavy at first; In some areas, it needs more than 10 kg, but in Guangdong and Guangxi, parent fish usually below 10 kg can also lay eggs.
