  1. The dispersion of red knots <em>Calidris canutus</em> in Africa—is southern Africa a buffer for West Africa?

    The dispersion of red knots <em>Calidris canutus</em> in Africa—is southern Africa a buffer for West Africa?

    Item type: Journal Article • Journal: African Journal of Marine Science
    The Siberian subspecies of the red knot Calidris canutus canutus spends the non-breeding season largely in West Africa (Mauritania and Guinea Bissau), where approximately half a million occurred in the 1980s. It was a rarely seen in southern Africa in...
  2. 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...
  3. When plenty is not enough: an assessment of the white stumpnose (<em>Rhabdosargus globiceps</em>) fishery of Saldanha Bay, South Africa

    When plenty is not enough: an assessment of the white stumpnose (<em>Rhabdosargus globiceps</em>) fishery of Saldanha Bay, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    White stumpnose Rhabdosargus globiceps is the main target of the linefishery in Saldanha Bay. Increased fishing pressure over the last three decades, particularly by the recreational sector, has led to concerns regarding sustainability of the local white stumpnose stock. The...
  4. The distribution and habitat in the Knysna Estuary of the endemic South African mudsnail <em>Hydrobia knysnaensis</em> and the influence of intraspecific competition and ambient salinity on its abundance

    The distribution and habitat in the Knysna Estuary of the endemic South African mudsnail <em>Hydrobia knysnaensis</em> and the influence of intraspecific competition and ambient salinity on its abundance

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The typical habitat of the rare, endemic South African mudsnail Hydrobia knysnaensis is the leaves of upper-shore Zostera capensis within high-salinity salt-marsh pools and channels. In the Knysna estuarine system, it is the numerically dominant member of a guild of...
  5. Physico-chemical and macrobenthic faunal characteristics of Kuramo Water, Lagos, southern Nigeria

    Physico-chemical and macrobenthic faunal characteristics of Kuramo Water, Lagos, southern Nigeria

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    A five-month study in 2001 of an enclosed lagoon, Kuramo Water in southern Nigeria, exposed to urban perturbation describes its physical, chemical and macrobenthic invertebrate characteristics. Of the 16 physical and chemical conditions studied at four sites within the bank-root...
  6. Oualidia lagoon, Morocco: an estuary without a river

    Oualidia lagoon, Morocco: an estuary without a river

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    This study describes some physical oceanography features of an estuary maintained by fresh groundwater inflow. The mesoscale variability of currents, temperature and salinity are documented from moored current meter observations of 12 days duration at three stations. Current speeds exceeded...
  7. Copper, zinc and iron concentrations in water, sediment and <em>Cynothrissa mento</em> (Regan 1917) from Ologe Lagoon, Lagos, Nigeria: a preliminary survey

    Copper, zinc and iron concentrations in water, sediment and <em>Cynothrissa mento</em> (Regan 1917) from Ologe Lagoon, Lagos, Nigeria: a preliminary survey

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The levels of Cu, Fe and Zn in water, sediment and Cynothrissa mento, a commercially important fish species, were investigated from April 2007 to March 2008 at three sites in Ologe Lagoon. Metal levels in the water column and C...
  8. Biodiversity and extracellular enzymatic activity of heterotrophic bacterial communities in Bardawil Lagoon, Egypt

    Biodiversity and extracellular enzymatic activity of heterotrophic bacterial communities in Bardawil Lagoon, Egypt

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The biodiversity of heterotrophic viable bacteria (209 isolates) in the hypersaline Bardawil Lagoon, Egypt, was studied. Composition and extracellular activities of viable culturable heterotrophic bacteria (VCHB) in the water and in non-colonised and seagrass-colonised sediments of Bardawil Lagoon were determined...
  9. Seasonal distribution of phytoplankton in the Aby lagoon system, Ivory Coast, West Africa

    Seasonal distribution of phytoplankton in the Aby lagoon system, Ivory Coast, West Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Seasonal variability of phytoplankton species composition, abundance and physical and chemical factors influencing phytoplankton dynamics were investigated in the Aby lagoon system, south-eastern Ivory Coast, covering the main climatic seasons in 2006–2007. Seasonal and spatial variability of nutrient concentrations in...
  10. Temporal variations in the food habits of some fish species in Lake Nokoué, Benin

    Temporal variations in the food habits of some fish species in Lake Nokoué, Benin

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Stomach contents of the 12 most abundant fish species in Lake Nokoué, Benin, collected between 2003 and 2005, were analysed for temporal variations in their diet. Several species showed seasonal shifts in their diets based on benthic prey abundance and...
