Silver carp, known scientifically as Hypophthalmichthys molitrix, is known as phytophague or silver carp, and is grown along with other carp fish in soil ponds and reservoirs. This fish is sometimes falsely referred to as azad fish which is a false name. Azad in Persian is used only for salmon.
Its habitat ranges from northern China to the Amur River, the border between China and Russia, and mainly in the freshwater of the major rivers, and feeds mainly on phytoplankton, detritus, and bacteria. Due to the nutritional status of the silver carp, which is one of the healthiest fish in the world and due to the density and diversity of phytoplankton in the ponds and reservoirs compared to the natural environment, it has caused the meat of its type to have high levels of fat, protein, iron, calcium and omega-3 than its non-cultivated type.
