    This study presents results from stomach content analysis of 123 largemouth bass, Micropterus salmoides, sampled at the mouth of the fishway leading into a 3 m high weir at the tidal limit of the Kowie River, Eastern Cape Province (33°32‘39“S,...
  2. Possible influences of a macroalgal bloom in eelgrass beds on fish assemblages in the lower Knysna Estuary, South Africa

    Possible influences of a macroalgal bloom in eelgrass beds on fish assemblages in the lower Knysna Estuary, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: M Pollard --- South African Environmental Observation Network, South Africa AK Whitfield --- South African Institute for Aquatic Biodiversity, South Africa AN Hodgson --- Department of Zoology & Entomology, South Africa
    The occurrence of a macroalgal bloom at eelgrass (Zostera capensis) sampling sites in the summer of 2014/2015 provided an opportunity to use underwater video cameras to monitor the possible effects of environmental change on fish diversity and abundance in the...
  3. Age, growth and per-recruit stock assessment of southern mullet <em>Chelon richardsonii</em> in Saldanha Bay and Langebaan Lagoon, South Africa

    Age, growth and per-recruit stock assessment of southern mullet Chelon richardsonii in Saldanha Bay and Langebaan Lagoon, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science • Authors: M Horton --- Department of Biological Sciences, South Africa D Parker --- Department of Biological Sciences, South Africa H Winker --- Branch: Fisheries Management, Department of Agriculture, South Africa SJ Lamberth --- Branch: Fisheries Management, Department of Agriculture, South Africa K Hutchings --- Anchor Environmental Consultants, South Africa SE Kerwath --- Department of Biological Sciences, South Africa
    The southern mullet Chelon richardsonii (Mugilidae) is the main target species of the inshore net fishery (gillnet and beach-seine) on the west coast of South Africa. The stock has displayed symptoms of overfishing, with a 28% reduction in the standardised...
  4. Assessing the thermal tolerance of a cosmopolitan eurythermal species, the flathead mullet <em>Mugil cephalus</em>

    Assessing the thermal tolerance of a cosmopolitan eurythermal species, the flathead mullet Mugil cephalus

    Item type: Journal Article • Journal: African Journal of Marine Science • Authors: DL Mukhari --- Rhodes University, South Africa A-R Childs --- Rhodes University, South Africa BA Ziko --- Rhodes University, South Africa TS Murray --- Rhodes University, South Africa
    Water temperature is a key abiotic factor affecting fish physiology, behaviour and distribution, with fluctuations impacting species assemblages and habitat use. The flathead mullet Mugil cephalus is a eurythermal species with a cosmopolitan distribution across tropical, subtropical and temperate coastal...
