    FIRST RECORD OF <em>OREOCHROMIS MACROCHIR</em> (BOULENGER, 1912) (PISCES:CICHLIDAE) FROM THE LIMPOPO RIVER IN SOUTHERN AFRICA.

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    During 1973/74, Barbus poechii, Oreochromis macrochir, O. andersonii, Serranochromis angusticeps, S. codringtonii, S. robustus and S. thumbergi from the Okavango System were introduced into the Shashe Dam (Limpopo System, Botswana). These species are alien to the Limpopo System. A fish...
  2. A preliminary survey of biotic composition of the Olifantspruit catchment, South Africa

    A preliminary survey of biotic composition of the Olifantspruit catchment, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    As a major tributary of the Nyl River, and ultimately for the Nylsvley wetland, the Olifantspruit, Limpopo province, South Africa, was investigated during the summer (high flow) and winter (low flow) of 2007 at three sites. This preliminary study used...
  3. Ecological status of Hout River Dam, Limpopo province, South Africa, using fish condition and health assessment index protocols: a preliminary investigation

    Ecological status of Hout River Dam, Limpopo province, South Africa, using fish condition and health assessment index protocols: a preliminary investigation

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The ecological status of Hout River Dam was evaluated in 2011 by assessing fish health, based on condition factor (K), health assessment index (HAI) and inverted parasite index (IPI), which provided a simple and rapid means of establishing the health...
  4. Seasonal dynamics and occurrences of three <em>Dactylogyrus</em> species on the gills of three cyprinids at Nwanedi–Luphephe dams in Limpopo province, South Africa

    Seasonal dynamics and occurrences of three <em>Dactylogyrus</em> species on the gills of three cyprinids at Nwanedi–Luphephe dams in Limpopo province, South Africa

    Item type: Journal Article • Journal: African Zoology
    This study investigated the seasonal dynamics and occurrence of dactylogyrids on the gills of three cyprinids at Nwanedi–Luphephe dams from January to October 2008. The hosts, Labeobarbus marequensis (n = 53), Barbus trimaculatus (n = 63) and Barbus radiatus (n = 46), were collected using gill...
  5. Response of instream animal communities to a short-term extreme event and to longer-term cumulative impacts in a strategic water resource area, South Africa

    Response of instream animal communities to a short-term extreme event and to longer-term cumulative impacts in a strategic water resource area, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Disturbance plays an integral part in generating heterogeneity required for ecosystem persistence, but the increased amplitude and duration of disturbances linked to drivers of global change could result in ecosystem shifts or collapse. Biomonitoring over time provides insights into trajectories...
  6. THE INVERTEBRATE FAUNA AND BIOTIC INDEX VALUE OF WATER QUALITY OF THE GREAT BERG RIVER, WESTERN CAPE

    THE INVERTEBRATE FAUNA AND BIOTIC INDEX VALUE OF WATER QUALITY OF THE GREAT BERG RIVER, WESTERN CAPE

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The invertebrate fauna was sampled at seven localities in the main stream of the Berg River in 1974. These results are discussed and compared with those of Harrison and Elsworth (1958). The results obtained were also used in applying the...
  7. A CHECKLIST OF THE FISH SPECIES OF THE CROCODILE AND MATLABAS RIVERS (LIMPOPO SYSTEM) OF THE TRANSVAAL

    A CHECKLIST OF THE FISH SPECIES OF THE CROCODILE AND MATLABAS RIVERS (LIMPOPO SYSTEM) OF THE TRANSVAAL

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    This paper reports on the results of a fish distribution survey of the Crocodile and Matlabas Rivers (Limpopo System). Fifteen species are recorded for the first time in the Matlabas River. Seven unlisted species are recorded for the Crocodile River,...
  8. THE COMPOSITION OF WATER COLLECTED FROM THE KUISEB RIVER, NAMIB DESERT, AT GOBABEB

    THE COMPOSITION OF WATER COLLECTED FROM THE KUISEB RIVER, NAMIB DESERT, AT GOBABEB

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    Water from the Kuiseb River at Gobabeb varied in ionic content. Various ionic dominance orders were recorded from flooding until the pools dried up. The quality was not suitable for irrigation, but would present no problems when used by stock...
  9. Adaptability of great cormorants <em>Phalacrocorax carbo</em> in a coastal environment demonstrated by their exploitation of introduced prey species and use of artificial breeding sites

    Adaptability of great cormorants <em>Phalacrocorax carbo</em> in a coastal environment demonstrated by their exploitation of introduced prey species and use of artificial breeding sites

    Item type: Journal Article • Journal: South African Journal of Marine Science
    An analysis of the contents of regurgitations of great cormorant Phalacrocorax carbo chicks at two coastal colonies in South Africa, one on an offhore island (St Croix) and the other at a saltworks in an estuary (Swartkops), revealed that the...
  10. THE LENGTH/MASS RELATIONSHIP AND CONDITION OF LABEO CAPENSIS IN THE CALEDON RIVER

    THE LENGTH/MASS RELATIONSHIP AND CONDITION OF LABEO CAPENSIS IN THE CALEDON RIVER

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The length mass relationship for a Labeo capensis population is described by the equation M = 0,0134 L2'999 where 2,999 represents a constant the value of which indicates isometric growth. There is very little difference between the length/mass relationship for...
