  1. The effects of kelp harvesting on its regrowth and the understorey benthic community at Danger Point, South Africa, and a new method of harvesting kelp fronds

    The effects of kelp harvesting on its regrowth and the understorey benthic community at Danger Point, South Africa, and a new method of harvesting kelp fronds

    Item type: Journal Article • Journal: South African Journal of Marine Science
    At Danger Point, South Africa, mariculture of the abalone Haliotis midae has led to increased demand for freshly harvested kelp Ecklonia maxima. This study estimates the biomass of E. maxima available for harvesting, investigates the effects of harvesting on the...
  2. Effects of wild and farm-grown macroalgae on the growth of juvenile South African abalone <em>Haliotis midae</em> Linnaeus

    Effects of wild and farm-grown macroalgae on the growth of juvenile South African abalone <em>Haliotis midae</em> Linnaeus

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The effect of various macroalgal diets on the growth of grow-out (>20 mm shell length) South African abalone Haliotis midae was investigated on a commercial abalone farm. The experiment consisted of four treatments: fresh kelp blades (Ecklonia maxima (Osbeck) Papenfuss)...
  3. A simple method for rapid estimation of <em>Ecklonia maxima</em> and <em>Laminaria pallida</em> biomass using floating surface quadrats

    A simple method for rapid estimation of <em>Ecklonia maxima</em> and <em>Laminaria pallida</em> biomass using floating surface quadrats

    Item type: Journal Article • Journal: African Journal of Marine Science
    In South Africa two species of kelp, Ecklonia maxima and Laminaria pallida, occur in quantities sufficient for commercial use. Currently, the former species is harvested in large quantities (about 5 000 tonnes wet weight per year) as abalone feed. In...
  4. Mapping and quantifying the South African kelp resource

    Mapping and quantifying the South African kelp resource

    Item type: Journal Article • Journal: African Journal of Marine Science
    Two species of kelp are exploited commercially in South Africa. Use of beach-cast Laminaria pallida is limited, although it comprises the bulk of the biomass on the northern West Coast. Ecklonia maxima dominates the southern West Coast and provides most...
  5. Repeat photography as a tool for detecting and monitoring historical changes in South African coastal habitats

    Repeat photography as a tool for detecting and monitoring historical changes in South African coastal habitats

    Item type: Journal Article • Journal: African Journal of Marine Science
    Repeat photography was used to illustrate long-term changes occurring in coastal habitats in the Western Cape, South Africa. Historic images were sourced from books and theses, the public and subject specialists, and repeat photographs were then taken from the same...
  6. 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...
