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. [1]
Molecular data suggest that Leucos diverged from Rutilus more than five million years ago, probably during the Messinian salinity crisis. The species of Leucos are typically of small size and they all live in still waters. They differ from Rutilus by the lack of spinous tubercles on scales and head in reproductive males, and also in the pharyngeal teeth formula. [1] The sister group to Leucos is the monotypic Sarmarutilus . [1]
There are currently five recognized species in the genus: [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.
Roach or The Roach may refer to:
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.
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 common bream, also known as the freshwater bream, bream, bronze bream, carp bream or sweaty bream, is a European species of freshwater fish in the family Cyprinidae. It is now considered to be the only species in the genus Abramis.
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).
Rutilus meidingeri is a species of freshwater fish in the family Cyprinidae. It is only found in three subalpine lakes in Austria and probably in few lakes of Slovakia. Since the 1980s, it has been extirpated from the German Lake Chiemsee and Austrian Traunsee.
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.
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 cactus roach is a species of fish in the family Cyprinidae, native to the basin of the Danube River upstream of the Iron Gate, very numerous in the Sava basin. It is also recorded in the Ukrainian Zakarpattian region. This freshwater fish is up to 55 cm (22 in) long, averaging 40 cm (16 in).
Ligula intestinalis is a tapeworm of fish, fish-eating birds and copepods, with species from each group featuring in its complex life cycle. Ligula intestinalis is a parasite that changes its intermediate host's behavior to become more vulnerable to its predators. In this case, Ligula intestinalis uses copepods and cyprinid fish as their intermediate host and develops inside of them to get to its final destination which is fish-eating birds. Plerocercoids, Ligula intestinalis larva, influence secondary intermediate hosts’ behavior, health, and fecundity. Additionally, Ligula intestinalis can cause fish-eating birds' gonads to remain undeveloped.
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 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.
Leucos panosi, also known as the Achelous roach, is a species of freshwater fish in the family Cyprinidae. Acheloos and Louros river systems in Greece, and lakes Trichonis and Ambrakia.
Nuptial tubercles or breeding tubercles are noticeable skin roughness or horny nodules that form on male fish during breeding. They are made of keratin, the same material as hair, hooves, and fingernails.
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.
