  1. Drift Patterns of Anchovy <em>Engraulis Capensis</em> Larvae in The Southern Benguela, and Their Possible Importance for Recruitment

    Drift Patterns of Anchovy <em>Engraulis Capensis</em> Larvae in The Southern Benguela, and Their Possible Importance for Recruitment

    Item type: Journal Article • Journal: African Journal of Marine Science
    In the southern Benguela, successful recruitment of Cape anchovy Engraulis capensis is highly variable and seems to be dependent on the spawning biomass only to a small extent. This paper investigates how the variations in the drift patterns of larvae...
  2. 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...
  3. Limits to the use of environmental indices to reduce risk and/or increase yield in the South African anchovy fishery

    Limits to the use of environmental indices to reduce risk and/or increase yield in the South African anchovy fishery

    Item type: Journal Article • Journal: African Journal of Marine Science
    Environmental indices that provide short-term predictions of recruitment have the potential to improve the average yield from highly productive resources that sustain recruit fisheries without an associated increase in risk (of resource 'collapse'). This is particularly true for cases where...
  4. Stage-dependent vertical distribution of pelagic fish eggs on the western Agulhas Bank, South Africa

    Stage-dependent vertical distribution of pelagic fish eggs on the western Agulhas Bank, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    The vertical distributions of eggs of anchovy Engraulis encrasicolus, sardine Sardinops sagax and round herring Etrumeus whiteheadi over the western Agulhas Bank, South Africa, were sampled between 0m and 100m, using an opening-closing WP-2 net, to investigate differences in developmental...
  5. Characterising and comparing the spawning habitats of anchovy <em>Engraulis encrasicolus</em> and sardine <em>Sardinops sagax</em> in the southern Benguela upwelling ecosystem

    Characterising and comparing the spawning habitats of anchovy <em>Engraulis encrasicolus</em> and sardine <em>Sardinops sagax</em> in the southern Benguela upwelling ecosystem

    Item type: Journal Article • Journal: African Journal of Marine Science
    The spawning habitats of anchovy Engraulis encrasicolus and sardine Sardinops sagax in the southern Benguela upwelling ecosystem were characterised by comparing their egg abundances with environmental variables measured concomitantly during two different survey programmes: the South African Sardine and Anchovy...
  6. Comparative trophodynamics of anchovy <em>Engraulis encrasicolus</em> and sardine <em>Sardinops sagax</em> in the southern Benguela: are species alternations between small pelagic fish trophodynamically mediated?

    Comparative trophodynamics of anchovy <em>Engraulis encrasicolus</em> and sardine <em>Sardinops sagax</em> in the southern Benguela: are species alternations between small pelagic fish trophodynamically mediated?

    Item type: Journal Article • Journal: African Journal of Marine Science
    The results of detailed morphological, experimental, field and modelling studies on various aspects of the trophic ecology of sardine Sardinops sagax and anchovy Engraulis encrasicolus in the Benguela ecosystem are synthesised, and differences in the trophodynamics of these two species...
  7. Comparison of assemblages and some life-history traits of seabirds in the Humboldt and Benguela systems

    Comparison of assemblages and some life-history traits of seabirds in the Humboldt and Benguela systems

    Item type: Journal Article • Journal: African Journal of Marine Science
    There are 21 and 15 species of seabirds that breed in the Humboldt and Benguela upwelling systems respectively. Only two species of gull are common to both systems, one as an endemic subspecies to the Benguela system. Eleven species and...
  8. A knowledge base for management of the capital-intensive fishery for small pelagic fish off South Africa

    A knowledge base for management of the capital-intensive fishery for small pelagic fish off South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    As a contribution to South Africa's move towards an ecosystem approach to fisheries management, this study explores the existence of common perceptions about South Africa's pelagic fishery between resource users and scientists. It represents a collaborative research effort of social...
  9. Indicators of sustainable fishing for South African sardine <em>Sardinops sagax</em> and anchovy <em>Engraulis encrasicolus</em>

    Indicators of sustainable fishing for South African sardine <em>Sardinops sagax</em> and anchovy <em>Engraulis encrasicolus</em>

    Item type: Journal Article • Journal: African Journal of Marine Science
    Six indicators were investigated for South African sardine Sardinops sagax and anchovy Engraulis encrasicolus: mean length of catch, length-at-50% maturity, total mortality, exploitation rate, ratio of bycatch, and centre of gravity of commercial catches. Sardine length-at-50% maturity is the most...
  10. Vertical distribution of small pelagic fish eggs and larvae on the eastern Agulhas Bank, South Africa

    Vertical distribution of small pelagic fish eggs and larvae on the eastern Agulhas Bank, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Vertical distributions of anchovy Engraulis encrasicolus and sardine Sardinops sagax eggs and larvae within the upper 50 m of the water column on the eastern Agulhas Bank, South Africa, were examined using discrete depth samples collected with a multiple, opening/closing...
