  1. Comparison of the effects of different linefishing methods on catch composition and capture mortality of South African temperate reef fish

    Comparison of the effects of different linefishing methods on catch composition and capture mortality of South African temperate reef fish

    Item type: Journal Article • Journal: African Journal of Marine Science
    The effects of hook size, bait type, water depth and fishing effort on the selectivity and capture mortality of reef fish were investigated in a standardised fishing experiment on the temperate south coast of South Africa. A total of 2...
  2. Effects of fishing on a temperate reef community in South Africa 1: ichthyofauna

    Effects of fishing on a temperate reef community in South Africa 1: ichthyofauna

    Item type: Journal Article • Journal: African Journal of Marine Science
    Exploitation of temperate reef fish not only affects the target species but potentially changes the composition of reef fish assemblages. This study investigated the effect of fishing on the ichthyofaunal community at protected and exploited sites around the Goukamma Marine...
  3. Intraspecific cleaning by juvenile Cape white seabream <em>Diplodus capensis</em> (Sparidae) off eastern South Africa

    Intraspecific cleaning by juvenile Cape white seabream <em>Diplodus capensis</em> (Sparidae) off eastern South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Juveniles of the Cape white seabream Diplodus capensis were observed cleaning adult conspecifics in a large tidepool off Sodwana Bay, South Africa. Although nine other tropical fish species were present and interacted with a nearby pair of Labroides cleaner wrasses,...
  4. Kelp forests in False Bay: urchins vs macroalgae in South Africa’s southwest coast biogeographical transition zone

    Kelp forests in False Bay: urchins vs macroalgae in South Africa’s southwest coast biogeographical transition zone

    Item type: Journal Article • Journal: African Journal of Marine Science
    Kelp forests along South Africa's southwest coast occur in a region of biogeographical overlap. Commonly referred to as transition-zone kelp forests, these dynamic ecosystems are particularly susceptible to grazing from species such as urchins. This study explores relationships between urchins...
  5. Production and quality norms of certain grass species for fodder flow planning: Pretoria area

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Four subtropical (Cenchrus. Digitaria, Anthephora and Sorghum) and two temperate grass species (Festuca. Agrotricum) were grown in a replicated field experiment at three levels of N application, with adequate P and K. Species were mown at 4‐, 6‐ and 8‐weekly...
  6. Effect of cutting frequency on the yield and quality of legumes and grasses under irrigation

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Four pasture legumes and seven grasses were subjected to a range of cutting frequencies during the 1980/81 season. A wide range of responses emerged, judged by both the dry matter and TDN yield responses of the different species. Whereas two...
  7. Production of pasture species in the winter rainfall region: Simulation of dry matter production

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Production data derived from cutting trials undertaken at a number of sites in the Winter Rainfall Region were used to derive equations for the prediction of the yield of a number of pasture species. Inputs into the models include climatic...
  8. Groei en produksie van ‘n aanal aangeplante weidings onder beweiding

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die groei en produksie onder beweiding van ‘n aantal aangeplante weidings is met behulp van die verskilmetode bepaal. Uit die data verkry in die proef is dit duidelik dat indien daar besproeiingswater beskikbaar is, groen materiaal dwarsdeur die jaar voorsien...
  9. A comparison of grass and grass/legume pastures under irrigation in the Outeniqua area of the southern Cape

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Two grass and five grass/legume pastures were evaluated over a period of two seasons at two seasonally set grazing pressures and under two grazing management systems, involving five and seven paddocks per flock and a seven‐day period of stay. Grazing...
  10. The role of the Tsitsikamma National Park in the management of four shore-angling fish along the south-eastern Cape coast of South Africa

    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...
