The Prussian carp, silver Prussian carp or Gibel carp, is a member of the family Cyprinidae, which includes many other fish, such as the common carp, goldfish, and the smaller minnows. It is a medium-sized cyprinid, and does not exceed a weight of 3 kilograms (6.6 lb) and a length of 45 centimetres (18 in). They are usually silver, although other color variations exist. They are omnivorous and feed on plankton, invertebrates, plant material and detritus. Originally from Siberia, they have been introduced to and are now inhabiting lakes, ponds, and slow-moving rivers throughout Europe, North America, and Asia.
Inhabits a wide variety of still water bodies and lowland rivers, usually associated with submerged vegetation or regular flooding. Can strongly tolerate low oxygen concentrations and pollution. Lake dwelling individuals move into river mouths to avoid low oxygen water in winter. Feeding larvae and juveniles occur in high-complexity habitats as reed belts. Feeds on plankton, benthic invertebrates, plant material and detritus. Spawns in shallow, warm shores on submerged vegetation. Able to reproduce from unfertilized eggs (gynogenesis). Life span reaches up to about 10 years. Eastern European or wild form of the goldfish.
Prussian carp has potential to cause economic and environmental damage by causing quantitative changes in community structure in becoming the dominant species and shifts in food chains, and by altering the physical and chemical properties of habitats. A major biological trait responsible for invasiveness in Prussian carp is its mode of reproduction. Invading populations are often triploid and composed of almost exclusively females that exhibit apomictic (gynogenetic) reproduction, using the sperm of other species to activate (but not fertilize) their own eggs.
