Silver Carp
Hypophthalmichthys molitrix
Silver carp, Hypophthalmichthys molitrix, is a large filter-feeding cyprinid native to eastern Asian rivers and floodplains. It has a deep, laterally compressed body, low-set eyes and fine gill rakers that strain plankton from the water. In large warm rivers, adults can grow quickly and produce huge numbers of eggs that drift with the current. The species is also famous for leaping from the water when startled by boat noise, a behavior that can injure people in invaded waterways.
Aquaculture uses silver carp as a low-trophic food fish and as part of pond polyculture, where it converts plankton into harvestable protein rather than depending heavily on pellets. Outside its native range, especially in the Mississippi River basin, management often focuses on preventing spread into new waters through barriers, monitoring, targeted harvest and strict transport rules. It is a poor choice for ornamental ponds. Large size, jumping behavior and ecological effects on native plankton-feeding fish make it a species for regulated production and professional fishery management.
