The quillback, also known as the quillback carpsucker, is a type of freshwater fish of the sucker family widely distributed throughout North America. It is deeper-bodied than most suckers, leading to a carplike appearance. However, the quillback is not a carp. It can be distinguished from carp by the lack of barbels around the mouth. The quillback is long-lived, with age up to 30 years, 44 years, and 52 years documented across different studies.
A carp is an oily freshwater fish from various species of the family Cyprinidae, a very large group of fish native to Europe and Asia. While carp is consumed in many parts of the world, they are generally considered an invasive species in parts of Africa, Australia and most of the United States.
The Eurasian carp or European carp, widely known as the common carp, is a widespread freshwater fish of eutrophic waters in lakes and large rivers in Europe and Asia. The native wild populations are considered vulnerable to extinction by the International Union for Conservation of Nature (IUCN), but the species has also been domesticated and introduced into environments worldwide, and is often considered a destructive invasive species, being included in the list of the world's 100 worst invasive species. It gives its name to the carp family, Cyprinidae.
Cyprinus is the genus of typical carps in family Cyprinidae. Most species in the genus are of East Asia origin with only the common carp in Western Asia and Europe; this invasive species has also been introduced to many other regions around the world. Cyprinus are closely related to some more barb-like genera, such as Cyclocheilichthys and Barbonymus (tinfoils). The crucian carps (Carassius) of western Eurasia, which include the goldfish, are apparently not as closely related.
Cyprinus micristius, the Dianchi carp, is a critically endangered species of ray-finned fish in the family Cyprinidae. It is found only in Lake Dianchi and its tributaries in Yunnan, China. The nominate subspecies from the lake itself has not been confirmed since the 1960s.
Cyprinus yilongensis is an extinct species of ray-finned fish in the family Cyprinidae. It was found only in Yilong Lake, Yunnan, China. It was last seen before 1981, when the lake was drained for 20 days, presumably causing the species' extermination.
Cyprinus barbatus is a species of ray-finned fish in the genus Cyprinus. It is endemic to Lake Erhai in Dali, Yunnan, China. It is negatively impacted by agricultural and domestic pollution and introduced species. The IUCN considers it as critically endangered and possibly extinct, but records as recent as the 2000s (decade) show that it likely does survive.
Cyprinus melanes is a species of ray-finned fish in the genus Cyprinus from the Kiến Giang River basin in Vietnam.
Cyprinus chilia is a species of ray-finned fish in the genus Cyprinus from several lakes in the Yunnan plateau of China.
Cyprinus dai is a species of ray-finned fish in the genus Cyprinus from the Black River basin in northern Vietnam.
Cyprinus exophthalmus is a species of ray-finned fish in the genus Cyprinus from freshwater habitats in the Quảng Bình Province in Vietnam.
Cyprinus fuxianensis is a species of ray-finned fish in the genus Cyprinus. The species is only known from Fuxian Lake in Yunnan. It has been impacted by habitat degradation, overfishing, and introduced species. It has declined by over 80% in the past 21 years. It was not recorded in a survey in 1995; IUCN considers it as Critically Endangered and possibly extinct.
Cyprinus hyperdorsalis is a species of ray-finned fish in the genus Cyprinus from the Black River basin in northern Vietnam.
Cyprinus ilishaestomus is a species of ray-finned fish in the genus Cyprinus. Critically endangered, it inhabits Qiluhu Lake, Yunnan, China.
Cyprinus intha is a species of ray-finned fish in the genus Cyprinus. The species is endemic to Inle Lake, a large, isolated freshwater lake on the Shan Plateau in eastern Myanmar. It is considered to be endangered, among other reasons, because of widespread hybridization with introduced Common Carp, Cyprinus carpio.
Cyprinus multitaeniatus is a species of ray-finned fish in the genus Cyprinus from the Xi River basin in China and Gâm River basin in Vietnam.
Cyprinus qionghaiensis is a critically endangered species of fish in the genus Cyprinus from Qiong Lake in Yunnan, China.
Cyprinus rubrofuscus, the Amur carp, is a species of cyprinid fish, and is the wild form of the well-known koi. It is widespread in the fresh waters of eastern Asia, native to China, Vietnam and Laos from the Amur to Red River basins, and has also been introduced outside its native range. It is known for its muddy flavor and boniness, hence, it is not commonly eaten by locals except when stewed.
Cyprinus yunnanensis is a critically endangered species of cyprinid fish in the genus Cyprinus from Qilu Lake in Yunnan, China. Despite surveys of the lake it has not been seen since the 1970s and it is possibly extinct. It reaches up to about 20 cm (8 in) in length.
Cyprinus quidatensis is a species of ray-finned fish in the genus Cyprinus from freshwater habitats in Vietnam.
