  1. Age and growth of the spinner shark <em>Carcharhinus brevipinna</em> (Müller and Henle, 1839) off the KwaZulu-Natal coast, South Africa

    Age and growth of the spinner shark <em>Carcharhinus brevipinna</em> (Müller and Henle, 1839) off the KwaZulu-Natal coast, South Africa

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Age and growth of the spinner shark Carcharhinus brevipinna off the KwaZulu-Natal coast of South Africa was investigated from vertebral growth ring counts of 67 specimens (54–213 cm precaudal length, PCL). Counts were made from sectioned vertebral centra by two...
  2. The diet of the ragged-tooth shark <em>Carcharias taurus</em> Rafinesque 1810 in the Eastern Cape, South Africa

    The diet of the ragged-tooth shark <em>Carcharias taurus</em> Rafinesque 1810 in the Eastern Cape, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    The ragged-tooth shark Carcharias taurus is a large predator of inshore coastal waters in the Eastern Cape, South Africa. Born at about 1m long and attaining approximately 3m, stomach content analyses have shown that it feeds largely on teleosts and...
  3. Shark fishing effort and catch of the ragged-tooth shark <em>Carcharias taurus</em> in the South African competitive shore-angling fishery

    Shark fishing effort and catch of the ragged-tooth shark <em>Carcharias taurus</em> in the South African competitive shore-angling fishery

    Item type: Journal Article • Journal: African Journal of Marine Science
    An integrated telephone and on-site questionnaire survey was used to estimate total shark fishing effort and specific catch of the ragged-tooth shark Carcharias taurus by coastal club-affiliated shore-anglers, primarily along the east coast of South Africa. Mean total shark fishing...
  4. White shark and other chondrichthyan interactions with the beach-seine (treknet) fishery in False Bay, South Africa

    White shark and other chondrichthyan interactions with the beach-seine (treknet) fishery in False Bay, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Public perception has been that an apparent increase in the nearshore occurrence of white sharks Carcharodon carcharias in False Bay, on the south coast of South Africa, can at least be partly attributed to beach-seine (treknet) operations attracting sharks into...
  5. The frequency and effect of shark-inflicted bite injuries to the reef manta ray <em>Manta alfredi</em>

    The frequency and effect of shark-inflicted bite injuries to the reef manta ray <em>Manta alfredi</em>

    Item type: Journal Article • Journal: African Journal of Marine Science
    Shark bite injuries on reef manta rays Manta alfredi off the coast of Inhambane, Mozambique, were examined over a three-year period (2003–2006). The frequency and seasonality of attacks, the rate of wound healing, and the possible identities of attackers were...
  6. First documented southern transatlantic migration of a blue shark <em>Prionace glauca</em> tagged off South Africa

    First documented southern transatlantic migration of a blue shark <em>Prionace glauca</em> tagged off South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    The first documented recapture of a South African-tagged juvenile blue shark Prionace glauca off Uruguay lends weight to the hypothesis of a single blue shark population in the South Atlantic. The presence of neonate blue sharks with umbilical scars and...
  7. Gear selectivity of large-mesh nets and drumlines used to catch sharks in the Queensland Shark Control Program

    Gear selectivity of large-mesh nets and drumlines used to catch sharks in the Queensland Shark Control Program

    Item type: Journal Article • Journal: African Journal of Marine Science
    Catches of sharks and bycatch in large-mesh nets and baited drumlines used by the Queensland Shark Control Program were examined to determine the efficacy of both gear types and assess fishing strategies that minimise their impacts. There were few significant...
  8. Liver lipids of Indian and Atlantic Ocean spinner <em>Carcharhinus brevipinna</em> and blacktip <em>Carcharhinus limbatus</em> sharks

    Liver lipids of Indian and Atlantic Ocean spinner <em>Carcharhinus brevipinna</em> and blacktip <em>Carcharhinus limbatus</em> sharks

    Item type: Journal Article • Journal: African Journal of Marine Science
    Shark liver oils are rich in polyunsaturated fatty acids, especially the n3 moieties. Data on the liver fatty acids of sharks from African waters, however, are limited. Liver samples from sharks from the western Indian Ocean off the east coast...
  9. Noteworthy elasmobranch records from Oman

    Noteworthy elasmobranch records from Oman

    Item type: Journal Article • Journal: African Journal of Marine Science
    Records of 11 elasmobranch species previously unreported from, or uncommon in, Omani waters are presented. Records new to Oman include Carcharhinus altimus, C. leiodon, Centrophorus isodon, Ctenacis fehlmanni, Himantura fai, Mobula eregoodootenke and Sphyrna zygaena, whereas noteworthy records of uncommon...
  10. 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...
