The silver carp in its natural range
The species is currently classified as near threatened in it original range, as its habitat and reproductive behavior are impacted by construction of dams, pollution, and overfishing. Population declines appear to have been particularly significant in the Chinese parts of its range.[1]

Related species
Two other species are in the genus Hypophthalmichthys, the bighead carp (H. nobilis) and the largescale silver carp (H. harmandi). The genus name Aristichthys has also sometimes been used for bighead carp, but is deprecated.[12] The bighead carp differs from the silver carp in its behavior (it does not leap from the water when startled) and also in its diet. Bighead carp are also filter feeders, but they filter larger particles than silver carp, and in general consume a greater proportion of zooplankton in their diets than silver carp, which consume more phytoplankton.[13] In at least some parts of the United States, bighead and silver carp hybridize in the wild and produce fertile offspring.[14]
The largescale silver carp is closely related to the silver carp, but its native range is to the south of that of the silver carp, mostly within Vietnam.[15] Unlike bighead and silver carp, largescale silver carp have not been widely introduced around the world for use in aquaculture, although at least one introduction was made to some waters of the Soviet Union, where they hybridized with the introduced silver carp.[16]
In North America
Silver carp were imported to North America in the 1970s to control algal growth in aquaculture and municipal wastewater treatment facilities, but escaped from captivity soon after their importation,[5] and are now considered a highly invasive species.[17]
Silver carp, with the closely related bighead carp, often reach extremely high
In 2020, Alabama Department of Conservation and Natural Resources found silver carp in Alabama's Pickwick and Wheeler reservoirs on the Tennessee River, but the species has not expanded its range in Alabama’s waterways.[20]
The
The silver carp is sometimes called the "flying" carp for its tendency to leap from the water when startled; it can leap up to 10 ft (3.0 m) into the air.[21] Boaters traveling in uncovered high-speed watercraft have been reported to be injured by running into airborne fish while at speed. A leaping silver carp broke the jaw of a teenager being pulled on an inner tube,[21] and water skiing in areas where silver carp are present is extremely dangerous.[22] Peculiarly, the extreme jumping behavior appears to be unique to silver carp of North America; those in their native Asian range and introduced to other parts of the world are much less prone to jumping. Although theories have been proposed (for example, the high densities the species reaches in parts of North America, or that the introduced North American population may have been based on a small number of particularly "jumpy" individuals), the reason for these geographic differences is not known for certain.[23][24]
