  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. 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...
