  1. 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...
  2. Factors affecting recapture rates of raggedtooth sharks <em>Carcharias taurus</em> tagged off the east coast of South Africa

    Factors affecting recapture rates of raggedtooth sharks <em>Carcharias taurus</em> tagged off the east coast of South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Understanding differences in the recapture rate between different tags (A-, B- and C-types), capture methods (rock-and-surf anglers, scientific divers and Natal Sharks Board protection nets) and life-history stages (juvenile and adult) is critical in evaluating the results obtained from cooperative...
  3. Spatial and seasonal distribution patterns of the ragged-tooth shark <em>Carcharias taurus</em> along the coast of South Africa

    Spatial and seasonal distribution patterns of the ragged-tooth shark <em>Carcharias taurus</em> along the coast of South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Catches from competitive shore-anglers, inshore boat-based anglers and sightings by spearfishers and divers were used to infer the spatial and seasonal movement patterns of young-of-the-year (<1.2m TL), juvenile (1.2–1.8m TL), sub-adult (1.8–2.4m TL) and adult (>2.4m TL) ragged-tooth sharks Carcharias...
  4. Aggressive behaviour of an adult male Cape fur seal (<em>Arctocephalus pusillus pusillus</em>) towards a great white shark (<em>Carcharodon carcharias</em>)

    Aggressive behaviour of an adult male Cape fur seal (<em>Arctocephalus pusillus pusillus</em>) towards a great white shark (<em>Carcharodon carcharias</em>)

    Item type: Journal Article • Journal: African Zoology
    This is a report of a marine predator (the white shark) being threatened by a member of the species on which it preys (a male Cape fur seal). Although these events may be rarely observed or occur infrequently, they may...
  5. A computer-aided framework for subsurface identification of white shark pigment patterns

    A computer-aided framework for subsurface identification of white shark pigment patterns

    Item type: Journal Article • Journal: African Journal of Marine Science
    Subsurface video footage can be used as a successful identification tool for various marine organisms; however, processing of such information has proven challenging. This study tests the use of automated software to assist with photo-identification of the great white shark...
