Hi

Ek weet nie of julle gister gesen het op TV, ek dink dit is op SABC 2 gewees, hulle is besig om alle karp in haties dood te maak en te verkoop aan die locals.

Volgens hulle is die karp een van die redes hoekom die water so lyk.

daar was karpe van ten minste 2 - 5kg wat dood gemaak was en hulle wil alles dood he en blykbaar geelvis inbring.

[align=center]Fishery Project at Hartbeespoort Dam off to a good start[/b][/align]
[align=center]Media release by the Department of Water Affairs and Forestry[/align]
[align=center]21 January 2008[/b][/align]
 

The Department of Water Affairs and Forestry’s Water Resource Manager at Hartbeespoort has expressed his excitement over the start up of the fishery project which is part of the Hartbeespoort Dam Remediation Programme, called Harties, Metsi a me - My water.  According to Mr Petrus Venter the first harvesting of the undesirable fish started on Tuesday, 15 January 2008, and the task manager for the fishery project, Professor Gert Steyn, says he is satisfied with the progress made thus far. 

Mr Venter says a crucial element of the programme is to restore the nutrient balance in the dam.  The food web plays an important role in this and can only be achieved if the trophic status in Hartbeespoort Dam has been restored.  At present the dam is dominated by the coarse species, namely Catfish, Carp and Canary Kurper. 

Mr Venter explained that the sun, which is an important source of energy, stimulates the nutrients in the water and causes the algae and hyacinths to grow.  As they die, some of them sink and the bottom feeders, namely the Catfish and the Carp, feed on the dead material in the sediment.  The result of their actions stirs up the sediment which causes the cycle of nutrient enrichment to repeat itself. 

“This shows that through the removal of the Catfish and Carp the food web can be restored”, he said.   

The fishery is a commercial entity that will harvest the dam of the undesirable species by utilising various techniques.  Harvesting activity on the water will generally be taking place in the evenings. The nets and lines will be left in the water overnight and extracted in the early mornings on a daily basis.  This will restore the desired trophic fish structure and contribute towards establishing an integrated aquaculture hub in the province.  The removed fish will be sold as a high source of protein.  This project will rely heavily on research and monitoring to ensure that the desired effect is obtained.   Mr Venter said “the fishery’s task will create significant job opportunities, especially for unemployed local residents which is an important part of this project.”

The remediation programme has been making steady progress.   The rainy weather lately has contributed towards there being fewer visible algae on the dam as the sun, which draws the algae to the top of the water’s surface was mostly absent.  In the meantime however the controlling and removal of algae are continuing and much success has been achieved by the placement of the first boom on the dam close to the dam wall.  The project is now ready to install the next two booms.  These will be placed at the railway bridge at Oberon and at the bridge at Lakeland.  

The public using the dam for recreation activities are requested to be on the look out for activities and specially coloured markers on the surface related to the remediation programme and are requested to avoid such areas.

Rumour ( ministry or health) has it that the water in the dam apart from no longer being fit to drink has now reached such a state that it is even harmfull when breathing in the stench that arises from the water.

There are plans to empty, yes I said empty the dam completely and truck away all the silt and sediment which has been deposited over the years.

It is alleged to be a 2 year project, where first the actual river flow( once empty) will be cleaned so that water can flow during the rainy season and then the rest of the dam ( containment area) is to be cleaned.

As said its a rumour, any comments on this.

@ Osie - Die rooi/pink bouys wat so in n ry op die water le hou hierdie nette op, hulle word nie elke dag gelig en skoongemaak nie. Die water gehalte op die oog af lyk al beter maar daar is soveel vis in die dam hulle het nog baie werk om te doen. Volgens n artikel wat ek gelees het is die kontrakteur geregtig om die vis wat uitgehaal word te smous en n addisionele inkomste te verdien. Daar is n paar manne op die forum wat gereeld daar hengel en jy kan maar by hulle posts sien die vis is nog volop.

Sover die Geelvis gaan glo ek nie dit sal suksesvol wees nie omdat die vis spesie maar sensitief is vir besoedeling.

Ouens, ek giggel as ek sien iemand het plan om die karp uit Harties te haal....Bloemhof word al JARE kommersieel genet...tonne vis per dag word uitgehaal, en na al die jare raak die hengel net beter en beter!!!Harties het baie meer natuurlike kos vir die vis as Bloemhof.....daai vis het een seisoen nodig om te spawn, en hulle begin weer van voor af...al manier hoe hulle harties se karps gaan uitkry is om die dam heeltemal te laat droogloop...het julle 'n idee hoe al daai vis gaan stink as hulle vrot???Neewat, dis manne wat nie weet hoe werk die natuur nie....kry die GEMORS uit die water wat inloop, en die dam sal homself uitsort....

 

[Kosie]

Ai ek wonder wat hulle met die monsters gaan maak wat volgens baie daar rond swem? Baie bekende ouens reken daar is karp en baber ver groter as die huidige rekords, hulle praat tot van wereld rekords! As dit die geval is hoop ek hulle kan daai visse kry voor hulle dood is en in n ander venue sit.

Here is a little history about Hartebeespoort Dam.

Its official name is Hartebeespoort Dam Resevoir. Construction of the dam wall was completed in 1923. The dam wall is 59 meters high and the catchment area is 4112 square km, the surface area 2062 hectares and the dam can hold 195 000 000 cubic meters of water. The dam supplies irrigation to farmers through a network of canals totalling a distance of 544 km. The Crocodile River is the main inflow into the dam. Since the dam was built the dam has suffered from severe Eutrophication from pollution resulting in high concentrations of Phosphates and Nitrates. Excessive growth of microscopic Algae, Cyanobacteria and Macrophytes have caused infestations such as Hyacinth.

Over the last 20 or so years, the farms and properties surrounding the dam have been developed into multi million rand residential estates, placing added pressure and demands on the dam. The Council managing this metropol is the big culprit for the continuous news reports making headlines because they are plain and simply incompetent to properly manage anything. 

You can see the dependants on this dam is huge and I can therefore not see that emptying this dam will ever happen as its history of poor water dates back to the early years of the previous century. Controlling what flows into the dam would be the most effective way of rehabilitation.

As far as the huge fish go, the dam is old enough to have those monsters lurking in there. I fished this dam as a young boy and I still fish there frequently, we dont eat the fish, but you almost guarenteed a good day on the water. The fish that come out are in remarkable good condition. The fish have definately adapted to the water conditions that have deteriorated more and more over time.

Soos "Deeg" gese het. Hul hoef net die gemors ,wat die dam al vir jare instroom ,te stop en die dam sal hom self uit sort!!

Hul sal my nooit oortuig dat die vis enige probleem skep nie. Hul kan dit vir hul oumas try vertel.Miskien sal hul dit glo.

Dit was maar net weer 'n gaval van iemand met 'n plan om geld te maak .

Hoe meer hul net .Hoemeer teel die vis

As jy daar op die boot sit en hengel sal jy nie glo hoeveel vis om jou speel nie, die dam het baie vis. Ek het ook nog nooit die water geruik stink nie, daar is wel algae en hyacinta maar wat wel stink is die eiland voor Ifafi. Daai eiland vrot letterlik soos n sewage plaas van al die duisende voels wat daar broei. Twee Saterdae terug moes ons van ons hengel plek af vlug toe die wind draai en na ons toe waai, dit het genuine geruik of een van die manne op die boot in sy broek getjorts het. LOL. Dalk is dit wat mense ruik want daai reuk is so sterk dat dit nie maklik verdun nie en jy dit ver sal kan ruik as die wind die dag sterk waai.

Munisipaliteit van Brits kan nie ANC naam onthou nie. Pomp al jare tonne riool elke dag in Harties direk !!

Niemand doen niks omtrent dit nie !!

Nou is dit die vis se skuld vra ek julle ???
