    POST-IMPOUNDMENT TRENDS IN THE FISH POPULATIONS OF THE HENDRIK VERWOERD DAM, SOUTH AFRICA

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    Fish population changes in the Hendrik Verwoerd Dam are presented as sampled with a series of multifilament gill nets from Spring 1971 to Summer 1977. During this period, species such as Barbus halubi (smallmouth yellowfish), B. kimberleyensis (largemouth yellowfish), Labeo...

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    New distribution records for four fish species in the Waterberg mountains of the Transvaal were established during surveys since 1987–92. Clarias theodorae was previously reported from one locality each in the Waterberg and Soutpansberg. The current survey disclosed its presence...
  3. PRELIMINARY OBSERVATIONS ON THE FISH POPULATIONS OF THE RECENTLY-IMPOUNDED KATSE RESERVOIR, LESOTHO

    PRELIMINARY OBSERVATIONS ON THE FISH POPULATIONS OF THE RECENTLY-IMPOUNDED KATSE RESERVOIR, LESOTHO

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    Katse is a new 35 km long impoundment on the Malibamatso River, a highland tributary of the Orange River in Lesotho. Two fishing surveys in 1996 yielded Barbus aeneus, Labeo capensis, Oncorhynchus mykiss and the occasional Austroglanis sclateri. Length frequency...
  4. Monitoring the recovery of a previously exploited surf-zone fish community in the St Lucia Marine Reserve, South Africa, using a no-take sanctuary area as a benchmark

    Monitoring the recovery of a previously exploited surf-zone fish community in the St Lucia Marine Reserve, South Africa, using a no-take sanctuary area as a benchmark

    Item type: Journal Article • Journal: African Journal of Marine Science
    Limiting accessibility to a fishing area can reduce fishing effort effectively and may therefore promote local recovery of depleted stocks. In January 2002, beach driving was banned in South Africa, thereby reducing angler access to large areas of the coastline,...
  5. 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,...
  6. FISH SPECIES IN STEIUTONTEIN DAN, TUGELA-VAAI SYSTEM, SOUTH AFRICA

    FISH SPECIES IN STEIUTONTEIN DAN, TUGELA-VAAI SYSTEM, SOUTH AFRICA

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    Two alien species and seven indigenous species, including two minnow species, were present in Sterkfontein Dam. Of the larger species, Barbus aeneus and Labco capensis were the dominant in terms of numbers.
  7. Pentachlorophenol-contaminated soil bioremediation: survival and efficacy of monoculture inoculants and enrichment of indigenous catabolic populations

    Pentachlorophenol-contaminated soil bioremediation: survival and efficacy of monoculture inoculants and enrichment of indigenous catabolic populations

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Survival and efficacy of monoculture inoculants of Flavobaderium sp. and Rhodococcus chlorophenolicus to bioremediate PCP-contaminated soil were examined under sterile and non-sterile conditions. Both species effected ≥ 40% catabolism in four weeks although inoculant survival was significantly higher with R...

    The role of the Tsitsikamma National Park in the management of four shore-angling fish along the south-eastern Cape coast of South Africa

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The role of the Tsitsikamma National Park (TNP) in the management of four important shore-angling fish (Diplodus sargus capensis, Diplodus cervinus hottentotus, Pachymetopon grande and Dichistius capensis) was evaluated using data obtained from two independent studies conducted over a similar...

    THE JUVENILE FISH POPULATION IN THE MARGINAL AREAS OF THE HENDRIK VERWOERD DAM

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    Small seine nets were used to collect minnow and juvenile fish from a variety of habitats around the 350 km shoreline of the Hendrik Verwoerd Darn. In addition several areas were sectioned off from the darn and poisoned. The species...
