  1. Mortality estimates and biological reference points for the Natal stumpnose <em>Rhabdosargus sarba</em> (Pisces: Sparidae) in KwaZulu-Natal, South Africa

    Mortality estimates and biological reference points for the Natal stumpnose <em>Rhabdosargus sarba</em> (Pisces: Sparidae) in KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    A per-recruit stock assessment was undertaken for the sparid Rhabdosargus sarba, which is caught in estuarine and marine shore fisheries in KwaZulu-Natal. Input parameters used in the analyses included age and growth parameters and mortality estimates from catch curves. The...
  2. Evaluation of Participation in and Management of the Transkei Shore Linefishery

    Evaluation of Participation in and Management of the Transkei Shore Linefishery

    Item type: Journal Article • Journal: African Journal of Marine Science
    Both roving creel and aerial surveys were used to quantify fishing effort along the former Transkei coast. A stratified random sampling procedure was used during shore patrols to assess catch and effort, and a questionnaire survey provided information on total...
  3. Effects of fishing on the size and dominance structure of linefish of the Cape region, South Africa

    Effects of fishing on the size and dominance structure of linefish of the Cape region, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    A dataset of linefish catch, effort and fish size distribution records has been assembled from archives to cover three short periods over the 100 years from 1897 to 1998 in four regions of the former Cape Colony, South Africa. Linefish...
  4. Validation of the periodicity of opaque zone formation in the otoliths of four temperate reef fish from South Africa

    Validation of the periodicity of opaque zone formation in the otoliths of four temperate reef fish from South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    An oxytetracycline (OTC) marker was used to validate the periodicity of opaque zone deposition in the otoliths of Chrysoblephus laticeps, Cheimerius nufar, Cymatoceps nasutus (Sparidae) and Dichistius capensis (Dichistiidae) in the wild. Fish were injected with OTC and tagged with...
  5. Influence of the sardine run on selected nearshore predatory teleosts in KwaZulu-Natal

    Influence of the sardine run on selected nearshore predatory teleosts in KwaZulu-Natal

    Item type: Journal Article • Journal: African Journal of Marine Science
    The relationships between shore-angling catch rates of nearshore predatory teleosts in KwaZulu-Natal, South Africa, and the timing of the sardine run were examined using a multiple regression model. Results showed that catch rates of five (elf Pomatomus saltatrix, garrick Lichia...
  6. Long-term trends in the recreational shore-fishery for elf <em>Pomatomus saltatrix</em> (Pomatomidae) along the KwaZulu-Natal coast, South Africa

    Long-term trends in the recreational shore-fishery for elf <em>Pomatomus saltatrix</em> (Pomatomidae) along the KwaZulu-Natal coast, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Elf Pomatomus saltatrix account for between 28% and 80% of the annually recorded recreational shore-angling catch in KwaZulu-Natal, South Africa, and have been subjected to various management regimes over the past 33 years. Management of the elf fishery was amended...
  7. An assessment of participation, catch and effort in the KwaZulu-Natal shore-based marine linefishery, with comments on management effectiveness

    An assessment of participation, catch and effort in the KwaZulu-Natal shore-based marine linefishery, with comments on management effectiveness

    Item type: Journal Article • Journal: African Journal of Marine Science
    The primary purpose of this study was to evaluate the effectiveness of current management of the KwaZulu-Natal (KZN) shore-based marine linefishery. Methods used included a stratified-random creel survey and an associated questionnaire survey. The study was undertaken between February 2009...
  8. Reef fish display station-keeping and ranging behaviour in the Pondoland Marine Protected Area on the east coast of South Africa

    Reef fish display station-keeping and ranging behaviour in the Pondoland Marine Protected Area on the east coast of South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    This study assessed the role of the Pondoland Marine Protected Area (MPA) in the Eastern Cape province of South Africa by evaluating retention versus ‘spillover’ of exploited fishery species that were tagged in a 400 km2 no-take zone of the...
  9. Optimisation of underwater visual census and controlled angling methods for monitoring subtidal temperate reef fish communities

    Optimisation of underwater visual census and controlled angling methods for monitoring subtidal temperate reef fish communities

    Item type: Journal Article • Journal: African Journal of Marine Science
    Standardised sampling protocols for monitoring fish stocks are essential to assess changes in stock status and provide a means to evaluate the effectiveness of fisheries management measures, such as marine protected areas (MPAs). This study aimed to optimise two standard...
  10. Assessing the suitability of commercial fisheries data for local-scale marine spatial planning in South Africa

    Assessing the suitability of commercial fisheries data for local-scale marine spatial planning in South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    This study integrates fisheries logbook data with observer and vessel monitoring system (VMS) data in order to assess the accuracy of reported data and to develop high-resolution spatial data suitable for use in local-scale marine spatial planning analyses. Spatial assessments...
