  4. The Role of Estuaries in South African Fisheries: Economic Importance and Management Implications

    The Role of Estuaries in South African Fisheries: Economic Importance and Management Implications

    Item type: Journal Article • Journal: African Journal of Marine Science
    Existing catch data for 129 of 255 functional estuaries on the South African coastline were reviewed and the relationships between fish catch and estuary size, type and biogeographical region analysed using simple and multivariate models. The best predictive models were...
  5. Characteristics and value of the Thukela Banks crustacean and linefish fisheries, and the potential impacts of changes in river flow

    Characteristics and value of the Thukela Banks crustacean and linefish fisheries, and the potential impacts of changes in river flow

    Item type: Journal Article • Journal: African Journal of Marine Science
    This study describes the Thukela Banks crustacean and linefish fisheries and investigates the potential impacts of reduced flow from the Thukela River on the value of these fisheries. Data were obtained from published and unpublished material, key informants and government...
  6. A review of the ecology and management of temporarily open/closed estuaries in South Africa, with particular emphasis on river flow and mouth state as primary drivers of these systems

    A review of the ecology and management of temporarily open/closed estuaries in South Africa, with particular emphasis on river flow and mouth state as primary drivers of these systems

    Item type: Journal Article • Journal: African Journal of Marine Science
    Research in South African temporarily open/closed estuaries that includes studies on the hydrodynamics, sediment dynamics, macronutrients, microalgae, macrophytes, zoobenthos, hyperbenthos, zooplankton, ichthyoplankton, fishes and birds is used as a basis to review the ecology and management of this estuary type...
  7. Are African penguins worth saving? The ecotourism value of the Boulders Beach colony

    Are African penguins worth saving? The ecotourism value of the Boulders Beach colony

    Item type: Journal Article • Journal: African Journal of Marine Science
    Populations of the African penguin Spheniscus demersus have decreased dramatically over the past century, due in part to competition for food with commercial fisheries, and the species is now endangered as a result. Economic arguments are used to favour fisheries...
