  1. Observations on the Diel Vertical Distribution of Hydromedusae in the Southern Benguela

    Observations on the Diel Vertical Distribution of Hydromedusae in the Southern Benguela

    Item type: Journal Article • Journal: African Journal of Marine Science
    Diel vertical migration (DVM) of six common species of hydromedusae was investigated during two drogue studies conducted in St Helena Bay on the west coast of South Africa in February 1995. Clytia spp., Obelia spp. and Bougainvillia macloviana, were largely...
  2. Hydromedusae Off the Orange River Mouth, Southern Africa

    Hydromedusae Off the Orange River Mouth, Southern Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    A total of 242 zooplankton samples from the upper 100 m of the water column was collected discontinuously from March 1997 to January 1999 off the Orange River mouth on the west coast of southern Africa. Six species of hydromedusae...
  3. Ecosystem approach to fisheries management in the southern Benguela: a workshop overview

    Ecosystem approach to fisheries management in the southern Benguela: a workshop overview

    Item type: Journal Article • Journal: African Journal of Marine Science
    A workshop was held in Cape Town in December 2002 to introduce the concept of an ecosystem approach to fisheries (EAF) management in the southern Benguela, and to examine the options for implementing an EAF in South Africa. The workshop...
  4. An ecosystem approach to fisheries in the southern Benguela context

    An ecosystem approach to fisheries in the southern Benguela context

    Item type: Journal Article • Journal: African Journal of Marine Science
    The 2001 Reykjavík Declaration on Responsible Fisheries in the Marine Ecosystem and the Plan of Implementation of the 2002 World Summit on Sustainable Development highlighted the need in fisheries to look beyond considering only the target species and to consider...
  5. Contributions of the Benguela ecology programme to pelagic fisheries management in South Africa

    Contributions of the Benguela ecology programme to pelagic fisheries management in South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    In 1982, the Benguela Ecology Programme (BEP) created a formal, multi-institutional research partnership in South Africa. During the next two decades, the BEP directed many aspects of pelagic ecosystem research in the southern Benguela upwelling region, aiming to improve fisheries...
  6. An ecosystem framework for fisheries management in the southern Benguela upwelling system

    An ecosystem framework for fisheries management in the southern Benguela upwelling system

    Item type: Journal Article • Journal: African Journal of Marine Science
    A "four-step framework" for applying ecosystem approaches to fisheries management in the southern Benguela is proposed. First, static ecosystem models can be used to highlight important interactions by assessing the net trophic impacts of each species on all the others...
  7. Ecosystem approach to fisheries management in the northern Benguela: the Namibian experience

    Ecosystem approach to fisheries management in the northern Benguela: the Namibian experience

    Item type: Journal Article • Journal: African Journal of Marine Science
    The northern Benguela marine resources have a long history of questionable management primarily because of the limitations of management measures under the political framework of the time (either free access or under an international authority with no national representation, authority...
  8. Quantification and representation of potential spatial interactions in the southern Benguela ecosystem

    Quantification and representation of potential spatial interactions in the southern Benguela ecosystem

    Item type: Journal Article • Journal: African Journal of Marine Science
    This work explores the potential spatial interactions between 13 key commercial species of the southern Benguela ecosystem: sardine Sardinops sagax, anchovy Engraulis encrasicolus, round herring Etrumeus whiteheadi, horse mackerel Trachurus trachurus capensis, chub mackerel Scomber japonicus, chokka squid Loligo vulgaris...
  9. Modelling stock dynamics in the southern Benguela ecosystem for the period 1978–2002

    Modelling stock dynamics in the southern Benguela ecosystem for the period 1978–2002

    Item type: Journal Article • Journal: African Journal of Marine Science
    An ecosystem model of the southern Benguela was fitted to available time-series data for the period 1978–2002, to explore how changes in target fish populations in this ecosystem can be attributed to feeding interaction terms and population control patterns, the...
  10. How can science contribute to an ecosystem approach to pelagic, demersal and rock lobster fisheries in South Africa?

    How can science contribute to an ecosystem approach to pelagic, demersal and rock lobster fisheries in South Africa?

    Item type: Journal Article • Journal: African Journal of Marine Science
    South Africa is committed to moving towards an Ecosystem Approach to Fisheries (EAF) and has laid the foundations for this using a three-pronged approach: through a project (EAF Feasibility Study) under the Benguela Current Large Marine Ecosystem Programme; through a...
