The term Asian carp can be confusing, because it is generally applied to a group of related species, including the bighead (Hypophthalmichthys nobilis), silver (Hypophthalmichthys molitrix), grass (Ctenopharyngodon idella), and black carp (Mylopharyngodon piceus). These fish can get quite large, up to 110 pounds, and they eat copious amounts of plankton. They are related to goldfish, Koi, and the common carp (Cyprinus carpio). The latter has already been established as an invasive species across most of North America for more than a century.
