Sawfin
It is also listed as Endangered by the Nature Conservation Ordinance of Western Cape Province. For the time being, it may not be killed or caught. Considerable populations are found in the Cederberg Wilderness Area, Matjies River Nature Reserve and Oorlogskloof Nature Reserve. In 2004, the Greater Cederberg Biodiversity Corridor was established by CapeNature and private landowners to better preserve and develop high-quality habitat. This project aims at restoring the river ecosystems for sustainable development. The sawfin has been bred in captivity at the Clanwilliam Yellowfish Conservation Station, but captive breeding success is not sufficient and improved techniques are needed.
