  1. The role of the Tsitsikamma National Park in the management of four shore-angling fish along the south-eastern Cape coast of South Africa

    The role of the Tsitsikamma National Park in the management of four shore-angling fish along the south-eastern Cape coast of South Africa

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The role of the Tsitsikamma National Park (TNP) in the management of four important shore-angling fish (Diplodus sargus capensis, Diplodus cervinus hottentotus, Pachymetopon grande and Dichistius capensis) was evaluated using data obtained from two independent studies conducted over a similar...
  2. Ecological status and role of the Mfolozi–Msunduzi estuarine system within the iSimangaliso Wetland Park, a World Heritage Site on the south-east coast of South Africa

    Ecological status and role of the Mfolozi–Msunduzi estuarine system within the iSimangaliso Wetland Park, a World Heritage Site on the south-east coast of South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The original structure and functioning of the historical Mfolozi–St Lucia estuarine system are described and anthropogenic impacts, which resulted in the Mfolozi and Msunduzi rivers being separated from the St Lucia Estuary and having their own combined mouth to the...
  3. Bayesian analysis of allozyme markers indicates a single genetic population of kingklip <em>Genypterus capensis</em> off South Africa

    Bayesian analysis of allozyme markers indicates a single genetic population of kingklip <em>Genypterus capensis</em> off South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Kingklip Genypterus capensis inhabit deep continental shelf and slope waters off southern Africa and are now largely harvested as a bycatch in trawl and longline fisheries for Cape hakes Merluccius spp. Regional differences in growth, vertebral count and otolith morphology...
  4. St Helena Bay (southern Benguela) then and now: muted climate signals, large human impact

    St Helena Bay (southern Benguela) then and now: muted climate signals, large human impact

    Item type: Journal Article • Journal: African Journal of Marine Science
    The development of suitable reference states for ecosystem-based management requires documentation of changes in structure and functioning of marine ecosystems, including assessment of the relative importance of bottom-up and top-down processes as drivers of change. We used monitoring data available...
  5. Comparing fish communities in sanctuaries, partly protected areas and open-access reefs in South-East Africa

    Comparing fish communities in sanctuaries, partly protected areas and open-access reefs in South-East Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Fish were surveyed by visual census on offshore reefs in Mozambique and eastern South Africa to compare (a) fully-protected ‘sanctuary’ areas, (b) ‘partly protected’ areas where recreational diving and limited fishing are permitted, and (c) ‘open’ unprotected areas. Community composition...
  6. Shallow-water, nearshore current dynamics in Algoa Bay, South Africa, with notes on the implications for larval fish dispersal

    Shallow-water, nearshore current dynamics in Algoa Bay, South Africa, with notes on the implications for larval fish dispersal

    Item type: Journal Article • Journal: African Journal of Marine Science
    Nearshore currents play a vital role in the transport of eggs and larval stages of fish. However, little is known about their complexity and the implications for dispersal of fish larvae. The study describes the complexity of the shallow nearshore...
  7. Abyssal scavenging demersal fauna at two areas of contrasting productivity on the Subantarctic Crozet Plateau, southern Indian Ocean

    Abyssal scavenging demersal fauna at two areas of contrasting productivity on the Subantarctic Crozet Plateau, southern Indian Ocean

    Item type: Journal Article • Journal: African Journal of Marine Science
    The Crozet Plateau is situated below typical high-nutrient, low-chlorophyll (HNLC) waters of the southern Indian Ocean. The area to the east of the Crozet Islands experiences high levels of surface productivity during the austral summer due to natural iron enrichment...
  8. First tracking of white stumpnose <em>Rhabdosargus globiceps</em> (Sparidae) in a South African marine protected area

    First tracking of white stumpnose <em>Rhabdosargus globiceps</em> (Sparidae) in a South African marine protected area

    Item type: Journal Article • Journal: African Journal of Marine Science
    There is a growing recreational fishery for white stumpnose Rhabdosargus globiceps (Sparidae) in Langebaan Lagoon, part of South Africa's West Coast National Park. The upper reaches of the lagoon are protected from fishing, but the extent to which the closure...
  9. Area utilisation and activity patterns of roman <em>Chrysoblephus laticeps</em> (Sparidae) in a small marine protected area

    Area utilisation and activity patterns of roman <em>Chrysoblephus laticeps</em> (Sparidae) in a small marine protected area

    Item type: Journal Article • Journal: African Journal of Marine Science
    Information on the movement of fish is vital to determine the effectiveness of marine protected areas (MPAs) for fish conservation and fisheries management. This study investigates area utilisation and activity patterns of 13 adult roman Chrysoblephus laticeps (Sparidae) using telemetry...
  10. Effects of fishing on a temperate reef community in South Africa 1: ichthyofauna

    Effects of fishing on a temperate reef community in South Africa 1: ichthyofauna

    Item type: Journal Article • Journal: African Journal of Marine Science
    Exploitation of temperate reef fish not only affects the target species but potentially changes the composition of reef fish assemblages. This study investigated the effect of fishing on the ichthyofaunal community at protected and exploited sites around the Goukamma Marine...
