The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Carassius gibelio (Bloch, 1782)

Common name: Prussian carp

Synonyms and Other Names: Gibel carp

Taxonomy: available through www.itis.govITIS logo

Identification: Kottelat and Freyhof (2007) describe Carassius gibelio as being silvery-brown in color with 37-52 gill rakers and 5 ½ branched anal rays; the last simple anal and dorsal rays are strongly serrated; and the peritoneum (lining of the abdominal cavity) is black. This species is morphologically similar to goldfish, Carassius auratus, and common carp, Cyprinus carpio, which could lead to misidentification (Docherty et al. 2017).

Size: Up to 35 cm standard length (SL) (Kottelat and Freyhof 2007)

Native Range: Central-eastern Europe to Siberia (Perdikaris et al. 2012)

Ecology: This species inhabits a wide variety of fresh water bodies including ponds, lakes, and slow-running rivers and streams, usually associated with submerged vegetation and/or regular flooding events (Kottelat and Freyhof 2007, Perdikaris et al. 2012). In the northern portion of its native range where temperatures are cooler, spawning occurs at 3-4 years of age, but occurs at 1-2 years in southern Europe from May-July when water temperatures are above 14°C (Kottelat and Freyhof 2007). Spawning occurs in shallow water along warm shorelines on submerged vegetation (Kottelat and Freyhof 2007, Paschos et al. 2004).
This species is a generalist omnivore feeding on plankton, benthic invertebrates, plant material, filamentous algae, and detritus (Kottelat and Freyhof 2007, Özdilek and Jones 2014).
Prussian carp can reproduce sexually or via gynogenesis, in which the female uses the sperm from a related species (i.e., other cyprinids) to activate the development of the egg, however the sperm does not contribute to the genetic composition of the offspring (Kottelat and Freyhoff 2007, Paschos et al. 2004). Gynogenetic populations are most prevalent in newly invaded habitats (Tarkan et al. 2012).

Means of Introduction: The means of original introduction to North America is currently unknown but potentially occurred through contaminated shipments of other aquaculture species or through aquarium or bait fish releases (Elgin et al. 2014). Dispersal has been facilitated by artificial irrigation waterways (Elgin et al. 2014) and likely human mediated transport (Docherty et al. 2017).

Status: This species is established in Alberta and Saskatchewan provinces of Canada (Docherty et al. 2017). An attempt at population control with three-pass electrofishing in tributaries of the Red Deer River in Alberta was not successful, in fact Prussian carp abundances were significantly higher post-removal (Card et al. 2020). Docherty et al. (2017) estimate the spread of Prussian carp to be 233-1250 km2 per year in Alberta.

Impact of Introduction: Prussian carp have the potential to compete for resources with native species. Docherty et al. (2017) found Prussian carp habitat preference overlaps closely with sunfish (Centrarchidae). Their diet preference overlaps with suckers (Catostomidae). Tarkan et al. (2012) found Prussian carp to interfere with spawning of native cyprinids potentially resulting in decreased population size of the latter.
In a mesocosm experiment, the presence of Prussian carp increased total suspended solids in the water column, enhanced the growth of planktonic algae, decreased light conditions, reduced benthic algae growth, reduced zooplankton biomass, and prevented submerged macrophyte development ultimately enhancing eutrophication (Razlutskij et al. 2021).

Remarks: Prussian carp’s morphological similarity to goldfish and common carp could lead to misidentification and thereby underestimation of extent of invaded range (Docherty et al. 2017).
In a laboratory experiment, mallard ducks were fed Prussian carp eggs. While only a small amount (0.25%) of the eggs were recovered from the duck feces, a few had viable embryos within the egg and two survived beyond hatching, suggesting that bird-mediated dispersal, albeit a small one, is possible (Lovas-Kiss et al. 2020).
