    An overview of the living marine resources of Namibia

    Item type: Journal Article • Journal: South African Journal of Marine Science
    This paper gives an overview of the main living marine resources of Namibia. It focuses on the scientific research conducted during the past decade as input to the management of these resources. The distribution and habitats of the most important...
  2. Assessment of resource availability and suitability for subsistence fishers in South Africa, with a review of resource management procedures

    Assessment of resource availability and suitability for subsistence fishers in South Africa, with a review of resource management procedures

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The availability of resources and their suitability for subsistence and small-scale commercial fishers in South Africa were assessed and appropriate options for the management of resources recommended. Assessment of current resource utilization and recommendations for future subsistence and/or small-scale commercial...
  3. Human impact on lake ecosystems: the case of Lake Naivasha, Kenya

    Human impact on lake ecosystems: the case of Lake Naivasha, Kenya

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Lake Naivasha is a wetland of national and international importance. However, it is under constant anthropogenic pressures, which include the quest for socioeconomic development within the lake ecosystem itself as well as other activities within the catchment. The lake is...
  4. Megabenthos and benthopelagic fishes on Southeast Atlantic seamounts

    Megabenthos and benthopelagic fishes on Southeast Atlantic seamounts

    Item type: Journal Article • Journal: African Journal of Marine Science
    In a descriptive study of megafauna of several Southeast Atlantic seamounts, multiple video-transects on upper slopes and summits documented the occurrence of benthic invertebrate taxa, primarily corals, regarded as indicators of vulnerable marine ecosystems (VMEs) as defined in international guidelines...
  5. THE USE OF MICROCOMPUTERS IN WATER RESOURCE MODELLING

    THE USE OF MICROCOMPUTERS IN WATER RESOURCE MODELLING

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    Microcomputers are the ideal tool for water resource modelling. Not only are they fast and computationally efficient, but they can also provide the user with dynamic graphical displays which greatly assist in the interpretation of the results of the analyses...
  6. Development of acoustic techniques for assessment of orange roughy <em>Hoplostethus atlanticus</em> biomass off Namibia, and of methods for correcting for bias

    Development of acoustic techniques for assessment of orange roughy <em>Hoplostethus atlanticus</em> biomass off Namibia, and of methods for correcting for bias

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Orange roughy form dense spawning aggregations in specific small areas in deep water on the Namibian shelf between late June and early August each year. The biomass in three such areas, where most commercial fishing occurs (the Johnies, Frankies and...
  7. A review of orange roughy <em>Hoplostethus atlanticus</em> fisheries, estimation methods, biology and stock structure

    A review of orange roughy <em>Hoplostethus atlanticus</em> fisheries, estimation methods, biology and stock structure

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Orange roughy Hoplostethus atlanticus are unusual fish. They form dense aggregations that have fuelled lucrative fisheries at great depths (600–1 400 m), especially off Namibia, New Zealand and Australia. They are thought to be very long-lived (>100 years, maturity at...
  8. Fishery characteristics and abundance estimates of the mangrove crab <em>Scylla serrata</em> in southern Tanzania and northern Moçambique

    Fishery characteristics and abundance estimates of the mangrove crab <em>Scylla serrata</em> in southern Tanzania and northern Moçambique

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The mud crab Scylla serrata is lightly exploited along the East African seaboard. This study reports on fishing practices and gives preliminary estimates of abundance and size structures of the mud crab populations in Utende, Chole Island and Juani Island,...
  9. Recommendations for the management of subsistence fisheries in South Africa

    Recommendations for the management of subsistence fisheries in South Africa

    Item type: Journal Article • Journal: South African Journal of Marine Science
    This paper summarizes recommendations for the management of previously marginalized and neglected subsistence fisheries in South Africa. The recommendations stem from the activities and analyses of a task group appointed by Government and mandated to provide advice about management of...
  10. Defining fishers in the South African context: subsistence, artisanal and small-scale commercial sectors

    Defining fishers in the South African context: subsistence, artisanal and small-scale commercial sectors

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Evolution of a new policy for the management of marine fisheries in South Africa led to the Marine Living Resources Act of 1998 (MLRA). Among other innovations, this requires that management strategies be developed for subsistence fisheries. As a prerequisite,...
