Pseudobarbus
''Pseudobarbus'' is a ray-finned fish genus in the family Cyprinidae. The type species is Burchell's redfin (''P. burchelli''). The scientific name is derived from the Ancient Greek ''pseudes'' ("false") and the Latin word ''barbus'' ("beard", in reference to the barbels of barbs). This genus contains some (and might contain all) of the South African redfins. It was originally proposed as a subgenus, but has since been found worthy of recognition as a full genus. This genus is restricted to southern Africa; all of its species were formerly placed in ''Barbus'', the genus of typical barbels and their relatives. One taxon was originally described as ''P. leonhardi'' – this, however, was a European fish for which the genus was erroneously proposed anew. It has since turned out to be nothing other than the barbel '' B. peloponnesius''.FishBase 009/ref> Species and systematics ''Pseudobarbus'' was placed in the paraphyletic " subfamily" Barbinae by those that recognize th ...

Pseudobarbus Afer
The Eastern Cape redfin (''Pseudobarbus afer'') is an African freshwater fish species in the family (biology), family Cyprinidae, this appears to be a species complex rather than a single species. It is endemism, endemic to the Sundays River, Sundays, Swartkops River, Swartkops and Baakens River, Baakens river systems of the Eastern Cape, South Africa, the fish in other rivers in the region have been suggested to belong to different species with four different lineages recognised, a forest lineage which appears to be more closely related to ''Pseudobarbus phlegethon'' of the Olifants River (Western Cape), Olifants River than the other lineages traditionally classified within ''P. afer'', the other lineages are the "St Francis" lineage which occurs in the rivers flowing into St Francis Bay and has been given the name ''Pseudobarbus swartzi'', the Krom lineage ''Pseudobarbus senticeps'' from the Krom River system and the "Mandela" lineage ''Pseudobarbus afer'' ''sensu stricto''.

Pseudobarbus Asper
The smallscale redfin ('Pseudobarbus asper'') is a freshwater fish in the family Cyprinidae which is endemic to South Africa. It is threatened by habitat destruction and the impact of invasive species. Description Its meristic data are that there are three-four dorsal fin spines and 7 rays while the nail fin has three spines and five rays and the lateral line has 37-40 small scales. It has a single pair of barbels and the males develop dark red fins and tubercules on the head when breeding. It grows to around 12 cm total length. Distribution ''Pseudobarbus asper'' occurs in the arid Karoo region of South Africa in the Gamtoos and Gourits River systems of the Eastern Cape in South Africa. Biology The smallscale redfin is found in turbid, eutrophic waters which have soft silty beds or over boulders to boulder in the Karoo region of South Africa. Its small size is understood to be an adaptation to the highly variable environment this fish inhabits, making it able to exploit ...

Burchell's Redfin
Burchell's redfin (''Pseudobarbus burchelli''), also known as the Tradouw redfin, Tradou redfin or Breede redfin, is an African freshwater fish species in the family Cyprinidae. ''P. burchelli'' is the type species of its genus ''Pseudobarbus'', and like all of these is tetraploid. The Berg River redfin (''P. burgi'') is a very close relative. It is endemic to the Western Cape Province of South Africa, where it occurs in the Moeras and Tradouw Rivers. Whether the similar fishes from the Breede River and Heuningnes River are also ''P. burchelli'' is undetermined.Swartz & Impson (2007) Two populations are known with certainty, one in the Moeras River at Barrydale and one at the Tradouw River at Tradouw's Pass. During summer, low water levels cut off gene flow between these two. The species inhabits deeper sections of the rivers' somewhat peaty water. Other fish are rare, and in Burchell's redfin's range these seem to consist of the introduced bluegill (''Lepomis macrochirus'') ...

Pseudobarbus Calidus
The Clanwilliam redfin (''Pseudobarbus calidus''), is a ray-finned fish species in the family Cyprinidae. It is placed with the South African redfins in ''Pseudobarbus''. It is tetraploid. Its closest living relative is probably the Twee River redfin (''P. erubescens'').de Graaf ''et al.'' (2007) Distribution and ecology It is endemic to the Western Cape Province of South Africa, where it occurs in the upper Olifants River and its tributaries – the Biedou, Boontjies, Boskloof, Breekkrans, Driehoeks, Dwars, Eselbank, Jan Dissels, Matijes, Noordhoeks, Oudste, Ratels, Rondegat, Thee and Tra Tra Rivers – near Clanwilliam and Keerom. It inhabits the pools and shallower water in larger clear and slightly acidic mountain streams. They are insectivores, eating mainly small mayflies (Baetidae), non-biting midges (Chironomidae) and ants (Formicidae). The breeding season is lengthy and lasts most of the summer, from November to January. Schools of adults form ...

Barbus
''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 (including the type species of ''Barbus''). Description and uses Their common names – barbs and barbels – refer to the fact that most members of the genera have a pair of barbels on their mouths, which they can use to search for food at the bottom of the water. Barbels are often fished for food; in some locations they are of commercial significance. The roe of barbels is poisonous, however. The large ''Barbus'' barbs are also often eaten in their native range. At Shanhûr in Egypt, remains of a jar from the sixth- to seventh-century AD were unearthed that contained fish bones. The fish were apparently pick ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). 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 ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Andrew Smith (zoologist)
Sir Andrew Smith (3 December 1797 – 11 August 1872) was a British surgeon, explorer, ethnologist and zoologist. He is considered the father of zoology in South Africa having described many species across a wide range of groups in his major work, ''Illustrations of the Zoology of South Africa''. Smith was born in Hawick, Roxburghshire. He qualified in medicine at the University of Edinburgh obtaining an M.D. degree in 1819, having joined the Army Medical Services in 1816. South Africa 1820–1837 In 1820 he was ordered to the Cape Colony and was sent to Grahamstown to supervise the medical care of European soldiers and soldiers of the Cape Corps. He was appointed the Albany district surgeon in 1822 and started the first free dispensary for indigent patients in South Africa. He led a scientific expedition into the interior and was able to indulge in his interests of natural history and anthropology. On several occasions, he was sent by governors on confidential missions to vis ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...
