Mooi River (Vaal)
The Mooi River ( af, Mooirivier) is a river in North West (South African province), North West Province, South Africa. It is a tributary of the Vaal River and belongs to the Upper Vaal Water Management Area. Course The Mooi rises near Koster, North West, Koster and flows southwards. During its course it flows into the Klerkskraal Dam, Boskop Dam and the Potchefstroom Dam. After crossing the town of Potchefstroom it bends southwestwards, shortly bending westwards before it empties into the Vaal River near the border with the Free State (South African province), Free State, about 15 km east of Stilfontein. Its main tributaries are the Wonderfonteinspruit (Mooirivierloop) and the Loop Spruit. The waters of the Mooi River and its reservoirs are polluted with heavy metals in its mid and lower course because of the large gold and uranium mining operations in the basin.

KwaZulu-Natal
KwaZulu-Natal (, also referred to as KZN and known as "the garden province") is a province of South Africa that was created in 1994 when the Zulu bantustan of KwaZulu ("Place of the Zulu" in Zulu) and Natal Province were merged. It is located in the southeast of the country, with a long shoreline on the Indian Ocean and sharing borders with three other provinces and the countries of Mozambique, Eswatini and Lesotho. Its capital is Pietermaritzburg, and its largest city is Durban. It is the second-most populous province in South Africa, with slightly fewer residents than Gauteng. Two areas in KwaZulu-Natal have been declared UNESCO World Heritage Sites: the iSimangaliso Wetland Park and the uKhahlamba Drakensberg Park. These areas are extremely scenic as well as important to the surrounding ecosystems. During the 1830s and early 1840s, the northern part of what is now KwaZulu-Natal was established as the Zulu Kingdom while the southern part was, briefly, the Boer ...

Andries Hendrik Potgieter
Andries Hendrik Potgieter, known as Hendrik Potgieter (19 December 1792 – 16 December 1852) was a Voortrekker leader and the last known Champion of the Potgieter family. He served as the first head of state of Potchefstroom from 1840 and 1845 and also as the first head of state of Zoutpansberg from 1845 to 1852. Beyond the Orange River Potgieter and his party moved inland to the present Free State, where they signed a treaty with the leader of the Barolong, Moroka. The treaty stipulated that Potgieter would protect the Baralong against the Matabele raiders, in exchange for land. The tract of land was from the Vet River to the Vaal River. The Matabele leader, Mzilikazi, was threatened by the white incursion into what he saw as his sphere of influence, which led to the Matabele's attack on the Potgieter laager in October 1836, at Vegkop, near the present-day town of Heilbron. The attack was beaten off, but the Matabele made off with most of the trekker oxen, crucial draugh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Carp

Mosquitofish
The western Mosquitofish (''Gambusia affinis'') is a North American freshwater fish, also known commonly, if ambiguously, as simply Mosquitofish or by its generic name, ''Gambusia'', or by the common name gambezi. Its sister species, the eastern mosquitofish ('' Gambusia holbrooki'') is also referred to by these names. Mosquitofish are small in comparison to many other freshwater fish, with females reaching a maximum length of and males a maximum length of . The female can be distinguished from the male by her larger size and a gravid spot at the posterior of her abdomen. The name "Mosquitofish" was given because the fish eats mosquito larvae, and has been used more than any other fishes for the biological control of mosquitoes. Gambusia typically eat zooplankton, beetles, mayflies, caddisflies, mites, and other invertebrates; mosquito larvae make up only a small portion of their diet. Mosquitofish were introduced directly into ecosystems in many parts of the world as a b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tilapia Sparrmanii
''Tilapia sparrmanii'', the banded tilapia, or vlei kurper, is a widespread and adaptable cichlid fish that is found in warmer freshwater habitats of southern Africa. They prefer water with ample plant cover, and occur naturally as far north as DR Congo and Tanzania. They have been introduced locally in the northern hemisphere. Younger banded tilapia feed on crustaceans and insect larvae, while the adults feed on terrestrial and aquatic plants and other debris. They undertake local migrations and may shoal before and during spawning time. They guard their own eggs, and although they may move eggs or fry in the mouth, they are not known to be actual mouthbrooders like several other tilapia Tilapia ( ) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most ... species.
