Gradually turn into herbivores; the body length reaches about 100 mm, and it can fully adapt to eating aquatic higher plants. Adult fish mainly feed on higher aquatic plants, such as Vallisneria, Verticillaster Hydrilla, Small Algae, Potamogeton, Duckweed, and Duckweed as the most favorite species; flooded grassy areas are often the fattening places for grass carp, and some dry grasses are also liked by grass carp. \x0d\x0aThe reproductive population of grass carp is mainly 4-5 years old, with a body length of 650-850 mm and a weight of 4-9 kg.
