YELLOWFISH WORKING GROUP NEWS

YWG April 2019 newsletter

 Dear YWG supporter,

 Report from the Western Cape by Dean Impson

The southwestern Cape where the three large indigenous cyprinid species of interest to yellowfish enthusiasts occur, namely the Berg-Breede whitefish, Clanwilliam sawfin and Clanwilliam yellowfish, has experienced a better rainfall season this year. This has benefitted habitat quality and quantity, especially during the dry season (October to March).  The Rondegat rehabilitation project continues to be a success, with ongoing recovery of the 4km stretch of river cleared of smallmouth bass.  The two redfin species (Clanwilliam and Fiery redfin) continue to expand their numbers and distribution in the rehabilitated area, and encouragingly there has been an ongoing increase in the numbers of Clanwilliam yellowfish.  Intensive monitoring of the river (thanks to Water Research Commission funding) has been replaced by long term monitoring of the recovery of the fish populations.  There has been very limited progress with the Krom rehabilitation project because of a 12 month delay in the signing of the three year contract between CapeNature and DEA: Natural Resource Management Programmes. The contract is expected to be signed in the next month or two which should see the project; which encompasses the Krom, Biedouw and Breekkrans rivers (all in the Cederberg) and Groenvlei Lake (southern Cape), implemented over the next three years. The focus on Groenvlei is to control the burgeoning population of carp by manual methods. Carp were illegally stocked in the vlei in the 1990s.

YWG September 2018 newsletter

Dear YWG supporter,

The August newsletter was all about the pollution in the mid-Vaal reaches but in the meantime the rivers in the Pretoria area are almost as bad according to Mariette Lieffrink of the FSE (Federation for a Sustainable Environment). Below is one of the photos of the foam-covered Hennops River which was included in a report to the DWS (Water Affairs & Sanitation) in July.

YWG August 2018 newsletter

Dear YWG supporter,

It will not surprise you that this month’s newsletter is devoted solely to the mid-Vaal and the complete destruction wrought by the discharge of at least 150 million litres of raw sewage daily into SA’s most important river from Emfuleni’s sewage plants which decant into the Barrage reservoir. This was a disaster just waiting to happen despite SAVE’s (Save the Vaal) heroic efforts over the last 12 years to prevent this.
