The Berg River redfin (Pseudobarbus burgi), also called the Berg redfin, is a type of freshwater fish found in Africa. It belongs to the Cyprinidae family, which includes carps and minnows. This fish is closely related to the Burchell's redfin (P. burchelli). The Berg River redfin has a special genetic makeup, meaning it has more sets of chromosomes than most animals.
Where Does It Live?
The Berg River redfin lives only in the Western Cape Province of South Africa. You can find it in the upper parts of the Berg River and its smaller connecting rivers. These smaller rivers include the Boesmans, Goedverwacht, Hugo, Krom, Leeu, and Wemmers Rivers.
Fishes similar to the Berg River redfin found in the Verlorenvlei area are actually a different species. Scientists are still studying them and haven't given them a formal name yet. In the past, these redfins were also found in the Eerste River.
Why Is It Endangered?
The Berg River redfin prefers clear, clean water that doesn't have many nutrients and isn't very hard. Sadly, this fish is considered an Endangered species by the IUCN, an international group that tracks endangered animals. Its numbers have dropped a lot in recent years, and in some rivers, like the Boesmans River, their population is still shrinking.
Main Threats
There are a few big reasons why the Berg River redfin is in trouble:
- Water Use: Too much water is being taken from the rivers for other uses, which leaves less for the fish.
- Invading Fish: Other fish that are not native to the area have been introduced and are causing problems.
- The smallmouth bass (Micropterus dolomieu) is a major threat. It eats young Berg River redfins and can wipe out entire groups of them.
- The rainbow trout (Oncorhynchus mykiss) is also a problem, especially in the colder, higher parts of the rivers where the bass can't live.
- Other Invaders: The impact of the African catfish (Clarias gariepinus), another fish not native to these rivers, is still being studied. It hasn't been in the area for very long.
Conservation Efforts
As of now, there isn't a specific plan in place to protect the Berg River redfin. Scientists and conservation groups are working to understand the threats better and hope to create a plan soon to help this unique fish survive.
