Fish were sampled from pools which were over 2 m deep in places but were as shallow as 30 cm in the vicinity of exposed bedrock. The substrate consisted of silt/sand with some small stony patches and water flow was sluggish to non-existent (Ref. 12527).

Biology ( anglais )

fourni par Fishbase
Inhabits pools and deeper flowing stretches of larger tributary streams and mainstreams. Feeds on detritus and small organisms, usually taken from the bottom. Breeds in summer. Fry and juveniles form large shoals, adults occur in small groups. Due to the development of towns, agriculture and industry, the habitat of the species has been destroyed. Populations have also been eliminated by introduced predatory fishes (Ref. 7248).

Burchell se rooivlerkie ( afrikaans )

fourni par wikipedia AF

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.

Voorkoms

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.

Habitat

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.

Bewaringstatus

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 ( anglais )

fourni par wikipedia EN

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]

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..
