Cyprinus carpio

common carp

Type Locality

Europe (Linneaus 1758).

Etymology/Derivation of Scientific Name

Cyprinus – generic name first used by Linnaeus and probably derived from Cyprus, the island home of Venus, and an indirect reference to the fish’s fecundity; carpio – Latin word for carp which was used by the Roman and Celtic peoples of Europe (Moyle 1976).

Characters

Maximum size: Up to 1220 mm TL (Allen 1980).

Coloration:  Dorsal region olive to gray; lateral region yellow-gold with silvery sheen; ventral region pale yellow.  Dorsal and caudal fins gold-olive, other fins yellowish.  Breeding males have a darker shade of the colors mentioned above with orange-gold fins.  Juveniles have a dark vertical bar on caudal fin base. Peritoneum dusky (Goldstein and Simon 1999).

Pharyngeal teeth count: 1, 1, 3-3, 1, 1 (Hubbs et al. 1991).

Counts: 35-38 lateral line scales (Hubbs et al. 1991); 21-33 gill rakers; 19 caudal fin rays; 18-22 dorsal fin rays; 4-6 anal fin rays; 14-18 pectoral fin rays; 8 or 9 pelvic fin rays (Heufelder and Fuiman 1982; Ross 2001).

Body shape: Deep body near origin of dorsal fin.

Mouth position: Terminal on young, becoming subterminal with age (Page and Burr 1991; Ross 2001).

External morphology: Upper jaw with barbels on each side; some morphologies without barbels (Hubbs et al. 1991).  Serrated spines on dorsal and anal fins. Swee and McCrimmon (1966) noted that nuptial tubercles are typically present on the head and pectoral fin rays of the male during the spawning season.

Internal morphology: Pharyngeal teeth are molar-like (Goldstein and Simon 1999).

Distribution (Native and Introduced)

U.S. distribution: Introduced in 1877 (native to Eurasia); widely distributed in North America below 50^th parallel; south to panhandle of FL, west through Mississippi River basin, becoming less common in west (Allen 1980).

Texas distribution: Introduced statewide.

Abundance/Conservation status (Federal, State, NGO):

Broad and stable distribution in North America (Panek 1987).

Habitat Associations

Macrohabitat: Small backwater areas to large rivers and reservoirs. Most abundant in large bodies of water (Hubbs et al. 1991).

Mesohabitat: Ubiquitous among habitats (Allen 1980) usually avoid swift currents. In the Sulphur River, Texas, one of four dominant species in open-water group collections; positively associated with greater depths in the upstream reach and with pool habitats during the high flow range (Morgan 2002). ). Upper lethal limit reported to range between 36°C and 41°C; species moderately tolerant of low dissolved oxygen conditions, with decrease in feeding and growth apparent at oxygen concentrations less than 3 ppm; species extremely tolerant of turbidity caused by particulate matter (clay, silt), the lethal level approaches 165,000 ppm (Panek 1987). Reported from brackish marshes with salinities up to 14 ppt (Crivelli 1981); however this species is rarely found in brackish areas as high salinities cause excretory problems and may interfere with water balance (Panek 1987). Young fish will bury themselves in mud or sand in an effort to avoid predation by birds (Panek 1987).

Biology

Spawning season: April to August, in Wisconsin (Miller 1952). Early-June to mid-July, in Lewis and Clark Lake (Missouri River), with water ranging between 18.3-23.9°C (Walburg and Nelson 1966). In Ontario, Canada, mid-May to early-August, with water temperatures ranging between 17 and 27°C; peak activity at 19-23°C (Swee and McCrimmon 1966). Spawning occurs from early spring (Panek 1987) to early summer (Breder and Rosen 1966).

Spawning location: Phytolithophils - nonobligatory plant spawner that deposit eggs on submerged items in shallow areas (Breder and Rosen 1966; Swee and McCrimmon 1966; Balon 1981; Simon 1999). Known to spawn in rivers, lakes, marshes, forested swamps, ponds, and sheltered, vegetated areas of streams; over aquatic vegetation, tree roots, on mud bottoms, and over debris covering bottom (Breder and Rosen 1966; Heufelder and Fuiman 1982; Panek 1987). In Ontario, Canada, spawning typically occurred in shallow water with muck bottom where eggs were scattered over available vegetation (Swee and McCrimmon 1966); occurred in shallow flooded area with abundant fixed vegetation, in southern France (Crivelli 1981).

Reproductive strategy: Nonguarders; open substratum spawners; phytolithophils: late hatching larvae with cement glands in free embryos, have larvae with moderately developed respiratory structures, and have larvae that are photophobic (Swee and McCrimmon 1966; Balon 1981; Simon 1999). Spawning occurs in shallow water (1-2 feet), both day and night, and is accompanied by much splashing. One or more males will chase the female, prodding her in an effort to induce extrusion of eggs. Eggs and milt are released into the water during this process; the eggs sinking and adhering to aquatic vegetation, algae, or firm substrates (Breder and Rosen 1966; Panek 1987).

Fecundity: Eggs ranging from 36,000 to 2,208,000 (Swee and McCrimmon 1966; Crivelli 1981; Panek 1987). Eggs demersal, adhesive, 1.5-2.1 mm diameter; incubation period 90 hours at 13-17°C, 50 hours at 25-32°C (Heufelder and Fuiman 1982; Panek 1987). Females can spawn multiple times a year (Swee and McCrimmon 1966).

Age at maturation: Variable; males generally mature by age 2 (or 305 mm TL) and females at three years old (or 432 mm TL; Panek 1987). Of Canadian populations, Swee and McCrimmon (1966) noted that males mature at ages 3 – 4, females at ages 4 – 5.

Migration: Relatively sedentary, at times they move moderate distances in streams, likely relating to habitat suitability (Funk 1955). In rivers, fish may migrate long distances to find suitable spawning conditions; in large reservoirs, fish inhabit overwintering areas near shallows were they will spawn (Panek 1987).

Longevity: Seldom beyond 20 years in the wild (Panek 1987), maximum known is 47 years for a fish kept in a pond; carp in warmer waters live <11 years (Carlander 1969).

Food habits: Species classified as invertivore/detritivore; benthic/filter feeder; grazer/suction feeder; main diet items include plant tissue, aquatic insects, crustaceans, annelids, and mollusks (Goldstein and Simon 1999). Feeding usually occurs in water <10 m, with fish rooting around the silty substrata; however, fish also consume plankton suspended in midwater, and insects or plankton trapped in the surface film. Bottom feeding individuals take mouthfuls of benthic organic matter and release it in the water column in order to select certain food items. Fish actively feed at sunrise and sunset. Diet of young fish primarily small crustacean, snails, and midge larvae; zooplankton selected from water column is sometimes an important diet item. Adults are omnivorous, consuming varying amounts of plant (rooted plants, algae, organic debris) and animal (midge larvae, crustaceans, small snails, freshwater clams) foods. Pharyngeal teeth well adapted for crushing and grinding larger food items (Panek 1987). Populations in two Colorado streams fed primarily on chironomid larvae and pupae; gut contents of stream fish also yielded large amounts of algae, sand, detritus, and terrestrial invertebrates. Fish inhabiting a Colorado pond fed primarily on chironomids, but also consumed large amounts of entomostracans and crayfish (Eder and Carlson 1977). In Lewis and Clark Lake (Missouri River), food items in order of volumetric importance were organic detritus (61%), insects (19%), microcrustaceans (10%), and phytoplankton (9%; Walberg and Nelson 1966).

Growth: Highly variable; maximum average length (TL) is 445 mm by the end of age 1, 622 mm by the end of age 2, 703 by the end of age 3, 782 mm by the end of age 4, and 831 by the end of age 5 (Carlander 1969).

Phylogeny and morphologically similar fishes:

Subfamily Cyprinidae within the cyprinin group (Cavender and Coburn 1992). Often hybridizes with the non-native goldfish, Carassius auratus (Breder and Rosen 1966; Allen 1980). Goldfish (Carrassius auratus) lack barbels, and molar-like pharyngeal teeth. 

Host Records:

Algae; Fungi; Protozoa (extensive); Trematoda (extensive); Cestoda; Nematoda (extensive); Leeches; Mollusca; Crustacea (extensive; Hoffman 1967; Panek 1987).

Commercial or Environmental Importance:

Individuals disturb benthos and increase turbidity as they stir up the bottom when feeding; consequently species regarded as pest fish in North America (Allen 1980; Panek 1987). Ecological success of this species has been attributed in part to its highly-developed senses of hearing, smell, and taste (Panek 1987).
