Limnology - the examine of inland waters - had its genesis in Europe concerning the flip of the century. The experiences of Fore1 on Lake Geneva have been of seminal price at present. It prospered below the early assistance of Thienemann, Naumann and Wesenberg-Lund in Europe and, quickly transplanted, of Birge and Juday in North the US (to identify quite a few early spirits). Now, liminology is a decent medical self-discipline taught at many universities, and limnologists are famous as vital members to our knowing of ways this fragile spaceship capabilities. All this said, it also needs to be said that limnology isn't really but a globally complete technological know-how. to ensure, a lot is understood approximately globally acceptable strategies, and the structural parts of aquatic ecosystems all over the world, yet limnological emphases, pursuits and matters stay primarily eu and North American in stability. a lot is understood approximately lakes and rivers in lower than one 5th of the world's land region (northern temperature regions); particularly little is understood approximately inland waters elsewhere.

The waters of the Transvaal system, in this instance exemplified by the Crocodile River in the Eastern Transvaal, are markedly different from those coming from the Karroo deposits and Bushveld granites, the latter showing quite considerable variation. These differences are matched by the effect the geological formations have upon the sediment load carried by rivers in the region. 6 have been taken from the report of the South African Government's Commission of Enquiry into Water Matters (1970).

Because of the generally low temperatures which pertain in this region, its ichthyofauna is restricted largely to the cold tolerant cyprinids. Of particular importance is the rare small Barbus species Oreodaimon quathlambae, the Drakensberg or Maluti minnow (Skelton 1986a), which because of the red fin patches shows some similarity to the red-finned minnows of the Olifants River to the west (p. 52). In this threatened endemic species we see the last remnants of an ancient assemblage, now relict and isolated.
