Rutilus is a genus of fish in the family Cyprinidae found in Eurasia. This genus is a widely distributed lineage of cyprinids and ranges from West Europe to East Siberia. [1]
In FishBase (2022), nine species are included in the genus: [1]
In a phylogeographic study, Levin et al. (2017) argue that the Ponto-Caspian taxa including R. caspicus, R. heckelii and R. stoumboudae could represent a single widespread species whose range extends to Siberia, to be named Rutilus lacustris , whereas R. kutum is included in R. frisii. [3]
The genera Leucos and Sarmarutilus have been recently separated from Rutilus and are closely related to it. [2]
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 3,000 species; only 1,270 of these remain extant, divided into about 200 valid genera. Cyprinids range from about 12 mm (0.5 in) in size to the 3 m (9.8 ft) giant barb. By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word kyprînos.
Barbus is a genus of ray-finned fish in the family Cyprinidae. The type species of Barbus is the common barbel, first described as Cyprinus barbus and now named Barbus barbus. Barbus is the namesake genus of the subfamily Barbinae, but given their relationships, that taxon is better included in the Cyprininae at least for the largest part.
The roach, or rutilus roach, also known as the common roach, is a fresh- and brackish-water fish of the family Cyprinidae, native to most of Europe and western Asia. Fish called roach can be any species of the genera Rutilus, Leucos and Hesperoleucus, depending on locality. The plural of the term is also roach.
The Caspian kutum or Caspian white fish is a member of the family Cyprinidae from brackish water habitats of the Caspian Sea and from its freshwater tributaries. It is typically a medium-sized fish, reaching 45–55 cm in length, rarely 70 cm, and weighing up to 4.00 kg, rarely 5.00 kg. It used to be very common and was harvested commercially. The population seems to have collapsed due to overfishing and marine pollution. Its flesh and roe are enjoyed as food, and highly prized in the Gilan and Mazandaran provinces in Iran.
Capoeta, also known as scrapers, is a genus of fish in the family Cyprinidae found in Western Asia. The distribution extends from Turkey to the Levant, to Transcaucasia, Iraq, Turkmenistan, in Armenia, particularly in lake Sevan and northern Afghanistan. This genus is most closely related to Luciobarbus and in itself is divided into three morphologically, biogeographically and genetically distinct groups or clades: the Mesopotamian clade, the Anatolian-Iranian clade and the Aralo-Caspian clade.
Chondrostoma is a genus of ray-finned fish in the family Cyprinidae. They are commonly known as nases, although this term is also used locally to denote particular species, most frequently the common nase . The common name refers to the protruding upper jaw of these fishes; it is derived from the German term Nase 'nose'.
Rutilus frisii, called the vyrezub, Black Sea roach, or kutum, is a species of fish in the family Cyprinidae, native to the basins of the Black Sea, Sea of Azov, and Sea of Marmara from the rivers of Bulgaria to western Transcaucasia and in Lake Iznik (Turkey).
The pigo is a species of freshwater fish in the roach genus Rutilus of the family Cyprinidae. The fish is native to northern Italy and Switzerland. It inhabits subalpine lakes of the northern Adriatic basin from the Livenza to the Po drainage, including Lakes Maggiore, Lugano, and Como.
Scardinius is a genus of ray-finned fish in the family Cyprinidae commonly called rudds. Locally, the name "rudd" without any further qualifiers is also used for individual species, particularly the common rudd. The rudd can be distinguished from the very similar roach by way of the rudd's upturned mouth, allowing it to pick food items such as aquatic insects from the surface of the water with minimal disturbance.
Squalius is a genus of fish in the family Cyprinidae found in Europe and Asia. Hybridization is not rare in the Cyprinidae, including this genus. S. alburnoides is known to be of ancient hybrid origin, with the paternal lineage deriving from a prehistoric species related to Anaecypris; the latter mated with ancestral S. pyrenaicus. Present-day S. alburnoides mates with sympatric congeners of other species.
Leuciscinae is a subfamily of the freshwater fish family Cyprinidae, which contains the true minnows.
Rutilus heckelii is a species of roach, a genus in the family Cyprinidae. This species occurs in freshened areas of Black and Azov Seas, entering the Don, Kuban, Dnipro, Dnister and rarely Danube drainages.
The Caspian roach is a species of roach fish living in the Caspian Sea. The Caspian roach can be distinguished from other roaches by its laterally compressed body, silvery grey iris, rounded snout and grey pectoral pelvic and anal fins with dark margins. The Caspian roach is semi-anadromous and inhabits mostly shallow coastal waters. It enters Volga, Ural, Emba, Terek and Kura drainages for spawning.
Sarmarutilus rubilio, known as the rovella or the South European roach, is a species of freshwater fish in the family Cyprinidae. It is native in the Tuscano-Latium district of Italy, both in waters draining to the Adriatic and Tyrrhenian Seas, and introduced further south in the country. Its natural habitats are rivers and freshwater lakes. It is threatened by introduced species and habitat loss.
Leucos is a genus of fishes in the family Cyprinidae, from Southern Europe. They are carp close to the genus Rutilus, and were only recently taxonomically distinguished from that genus.
Leucos aula is a species of freshwater fish in the family Cyprinidae. It is native to the Adriatic basin in southern Europe, originally occurring in Italy, Slovenia, Croatia, and Switzerland. It has been introduced to other parts of Italy. This is an abundant fish, occurring in canals, swamps, lakes, and streams with slow current and dense vegetation.
Leucos basak, the Albanian roach, Dalmatian roach or Croatian roach, is a species of freshwater fish in the family Cyprinidae. It is found in Albania, Bosnia and Herzegovina, Croatia, and Serbia and Montenegro.
Leucos ylikiensis is a species of freshwater fish in the family Cyprinidae. It is found only in Greece, in the Kifissos drainage and Lake Yliki. The other known population, in Lake Paralimni, was extirpated when the lake was drained. L. ylikiensis was described as a distinct species in 1991. It is threatened by habitat loss.
Nuptial tubercles are dermal structures present in 15 families of fish belonging to 4 orders of Actinopterygii – Salmoniformes, Gonorhynchiformes, Cypriniformes and Perciformes – used in the courtship and reproduction process. They consist of partially or fully keratinised cells that form a perceptible protrusion in certain regions, used to stimulate females during courtship. Their development is stimulated by hormones secreted by the pituitary and adrenal glands, and is induced shortly before the breeding season and discarded after. In some species, at least, there is a correlation between the level of androgens present in the endocrine system and the volume and complexity of tubercle growth.
Rutilus stoumboudae is a species of freshwater fish in the family Cyprinidae. It is found only in Greece, in Lake Volvi and is a lacustrine species adapted to still water. It is named for Maria Stoumboudi, in honour of her research on the ecology and conservation of the freshwater fishes of Greece.
