  1. Observations of individual humpback whales utilising multiple migratory destinations in the south-western Indian Ocean

    Observations of individual humpback whales utilising multiple migratory destinations in the south-western Indian Ocean

    Item type: Journal Article • Journal: African Journal of Marine Science
    Movements of humpback whales Megaptera novaeangliae among breeding regions within the southwestern Indian Ocean are poorly understood. Understanding the relationships among breeding regions is critical for effective conservation and management strategies. Through systematic comparisons of molecular genotypes and both systematic...
  2. Trends and interventions in large whale entanglement along the South African coast

    Trends and interventions in large whale entanglement along the South African coast

    Item type: Journal Article • Journal: African Journal of Marine Science
    The major causes of large whale entanglement in South Africa are static fishing gear, especially the type associated with the West Coast rock lobster Jasus lalandii industry, and large-mesh gillnets that are set off the coast of KwaZulu-Natal (KZN) to...
  3. Transit station or destination? Attendance patterns, movements and abundance estimate of humpback whales off west South Africa from photographic and genotypic matching

    Transit station or destination? Attendance patterns, movements and abundance estimate of humpback whales off west South Africa from photographic and genotypic matching

    Item type: Journal Article • Journal: African Journal of Marine Science
    Humpback whales Megaptera novaeangliae found off west South Africa (WSA) are known to display an atypical migration that may include temporary residency and feeding during spring and summer. At a regional scale there is uncertainty about how these whales relate...
  4. Migrations of humpback whales past Cape Vidal, South Africa, and an estimate of the population increase rate (1988–2002)

    Migrations of humpback whales past Cape Vidal, South Africa, and an estimate of the population increase rate (1988–2002)

    Item type: Journal Article • Journal: African Journal of Marine Science
    Shore-based surveys of migrating humpback whales Megaptera novaeangliae were undertaken from Cape Vidal, northern KwaZulu-Natal, South Africa, each year between 1988 and 1991, and in 2002. Daily observations of migrating whale groups were carried out from an approx. 60 m-high...
  5. Long-term trends in cetacean occurrence during the annual sardine run off the Wild Coast, South Africa

    Long-term trends in cetacean occurrence during the annual sardine run off the Wild Coast, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    During the austral winter, cetaceans and other apex predators follow the annual northeastward movement of shoaling sardines, known as the sardine run, along the southeast coast of South Africa, including a 400-km stretch called the Wild Coast. In total, 131...
  6. Multi-stakeholder collaboration yields valuable data for cetacean conservation in Gamba, Gabon

    Multi-stakeholder collaboration yields valuable data for cetacean conservation in Gamba, Gabon

    Item type: Journal Article • Journal: African Journal of Marine Science
    Private industry, the Government of Gabon and two international NGOs collaborated to conduct marine surveys off the coast of Gabon, Central Africa. Surveys addressed multiple objectives of surveillance and monitoring, the documentation of the distribution of and threats to the...
  7. First insights on spatial and temporal distribution patterns of humpback whales in the breeding ground at Sainte Marie Channel, Madagascar

    First insights on spatial and temporal distribution patterns of humpback whales in the breeding ground at Sainte Marie Channel, Madagascar

    Item type: Journal Article • Journal: African Journal of Marine Science
    The Sainte Marie Channel on the northeast coast of Madagascar is an important breeding ground for humpback whales; the first observation of birth was documented there, yet it has never been investigated for phenology and habitat use of humpback whales...
