Burchell se rooivlerkie (Pseudobarbus burchelli) is 'n varswatervis wat hoofsaaklik voorkom in die Breederivier in die Wes-Kaap, Suid-Afrika. Dit staan ook bekend as die Breederivier-rooivlerkie en in Engels as Burchell's redfin.
Die onvolwasse en jong volwasse visse is olyfbruin met verskeie vlekke en kolle, wat 'n gebroke streep vorm, op die lyf. Die gebroke streep eindig in 'n driehoek op die basis van die stertvin. Volwasse visse wat paar se kleur verdonker na 'n donker olyfbruin met die onderkant wat lig bly. Daar is twee pare baarde om die mond en volwasse visse het tuberkels op die kop. Die vis word tot 135 mm lank.
Die vis leef in poele en die dieper vloeiende gedeeltes van die groter sytakke en die hoofstroom. Hulle vreet detritus en klein organismes vanaf die bodem en paar in die somer. Die kleiner vissies leef in skole saam en die volwasse vissies in kleiner groepe.
Die vis is 'n kritiek bedreigde spesie aangesien sy habitat verklein word as gevolg van die ontwikkeling van dorpe, landbou en industrieë. Ingevoerde eksotiese visse teer op die vis as prooi.

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.[2]
It is endemic to the Western Cape Province of South Africa, where it occurs in the Moeras and Tradouw Rivers.[3] Whether the similar fishes from the Breede River and Heuningnes River are also P. burchelli is undetermined.[4]
Two populations are known with certainty, one in the Moeras River at Barrydale and one at the Tradouw River at Tradouws 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) and Banded Tilapia (Tilapia sparrmanii) only.[4]
The introduced smallmouth bass (Micropterus dolomieu) is expanding in the region and apparently destroys P. burchelli stocks as it does so. Human interference with the river's flow around Barrydale as well as water pollution have reached dangerous proportions. Consequently, Burchell's redfin is considered to be in serious danger of going extinct within a few years. It is assessed to be critically endangered by the IUCN; no conservation plan has been proposed for the species yet.[4]

Pseudobarbus burchelli is een straalvinnige vissensoort uit de familie van de eigenlijke karpers (Cyprinidae).[2] De wetenschappelijke naam van de soort is voor het eerst geldig gepubliceerd in 1841 door Smith.
In het Afrikaans heet de vis Breederivier-rooivlerkie (Breederivierroodvleugeltje) omdat hij vrijwel alleen in de Breederivier in de Zuid-Afrikaanse provincie West-Kaap aangetroffen wordt..
