  1. Diel and tidal variations in larval fish exchange in the mouth region of the Gamtoos Estuary, South Africa

    Diel and tidal variations in larval fish exchange in the mouth region of the Gamtoos Estuary, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Diel and tidal variations in density of larval fishes were monitored over one neap and one spring tidal cycle in the mouth region of the warm temperate Gamtoos Estuary, South Africa. Data were collected over two 24h periods, using mixed...
  2. Influence of oceanographic fronts and low oxygen on the distribution of ichthyoplankton in the Benguela and southern Angola currents

    Influence of oceanographic fronts and low oxygen on the distribution of ichthyoplankton in the Benguela and southern Angola currents

    Item type: Journal Article • Journal: African Journal of Marine Science
    The study focuses on ichthyoplankton populations in the southern Angola Current, the Angola-Benguela Front and the coastal upwelling area of the northern and central Benguela Current. The horizontal and vertical distributions of eggs and larvae of sardine Sardinops sagax, anchovy...
  3. Diet and prey selection in late-stage larvae of five species of fish in a temperate estuarine nursery

    Diet and prey selection in late-stage larvae of five species of fish in a temperate estuarine nursery

    Item type: Journal Article • Journal: African Journal of Marine Science
    The plankton assemblage of the permanently open Sundays Estuary in South Africa was sampled seasonally to provide further information on the feeding ecology of the larval stages of fishes in temperate estuaries. Collections were made between winter 2007 and autumn...
  4. The role of estuarine type in characterizing early stage fish assemblages in warm temperate estuaries, South Africa

    The role of estuarine type in characterizing early stage fish assemblages in warm temperate estuaries, South Africa

    Item type: Journal Article • Journal: African Zoology
    Assemblages of early stage fishes (larval and early juvenile stages) were investigated and compared in seven permanently open and five intermittently open estuarine systems on the warm temperate Eastern Cape coast of South Africa. Estuarine type, by virtue of mouth...
  5. The ‘suitcase hypothesis’: Can entrainment of meroplankton by eddies provide a pathway for gene flow between Madagascar and KwaZulu-Natal, South Africa?

    The ‘suitcase hypothesis’: Can entrainment of meroplankton by eddies provide a pathway for gene flow between Madagascar and KwaZulu-Natal, South Africa?

    Item type: Journal Article • Journal: African Journal of Marine Science
    Similarities in the marine fauna found off the coasts of southern Madagascar and KwaZulu-Natal Province (KZN), South Africa, led to the development of the ‘suitcase project,’ with the aim of establishing whether eddies that form off southern Madagascar may package...
  6. Metabolic activity throughout early development of dusky kob <em>Argyrosomus japonicus</em> (Sciaenidae)

    Metabolic activity throughout early development of dusky kob <em>Argyrosomus japonicus</em> (Sciaenidae)

    Item type: Journal Article • Journal: African Journal of Marine Science
    The physiology of fishes in the early stages of development remains poorly assessed despite the importance of identifying energy bottlenecks in organisms faced with changing environmental conditions. This study describes the metabolic activity of dusky kob Argyrosomus japonicus throughout its...
  7. A CHECKLIST OF THE FISH SPECIES OF THE CROCODILE AND MATLABAS RIVERS (LIMPOPO SYSTEM) OF THE TRANSVAAL

    A CHECKLIST OF THE FISH SPECIES OF THE CROCODILE AND MATLABAS RIVERS (LIMPOPO SYSTEM) OF THE TRANSVAAL

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    This paper reports on the results of a fish distribution survey of the Crocodile and Matlabas Rivers (Limpopo System). Fifteen species are recorded for the first time in the Matlabas River. Seven unlisted species are recorded for the Crocodile River,...
  8. FISH SPECIES IN STEIUTONTEIN DAN, TUGELA-VAAI SYSTEM, SOUTH AFRICA

    FISH SPECIES IN STEIUTONTEIN DAN, TUGELA-VAAI SYSTEM, SOUTH AFRICA

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    Two alien species and seven indigenous species, including two minnow species, were present in Sterkfontein Dam. Of the larger species, Barbus aeneus and Labco capensis were the dominant in terms of numbers.
  9. Interaction between Cape hake spawning and the circulation in the northern Benguela upwelling ecosystem

    Interaction between Cape hake spawning and the circulation in the northern Benguela upwelling ecosystem

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Cape hake in Namibian waters are demersal and mesopelagic spawners, spawning peaking offshore between 100 and 400 m deep, depending on local environmental conditions. The cross-shelf circulation, low-oxygen layers and mesoscale gyres are three important environmental factors influencing hake spawning...
  10. 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...
