  1. Fish distributions in the Rondegat River, Cape Floristic Region, South Africa, and the immediate impact of rotenone treatment in an invaded reach

    Fish distributions in the Rondegat River, Cape Floristic Region, South Africa, and the immediate impact of rotenone treatment in an invaded reach

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Alien fishes are considered the most serious threat to native headwater stream fishes in South Africa. A 4 km reach of the Rondegat River is the first section of a South African river to be rehabilitated through the attempted removal...
  2. Validation of growth zone deposition rate in otoliths and scales of flathead mullet <em>Mugil cephalus</em> and freshwater mullet <em>Myxus capensis</em> from fish of known age

    Validation of growth zone deposition rate in otoliths and scales of flathead mullet <em>Mugil cephalus</em> and freshwater mullet <em>Myxus capensis</em> from fish of known age

    Item type: Journal Article • Journal: African Journal of Marine Science
    Flathead mullet Mugil cephalus and freshwater mullet Myxus capensis are important components in South African estuarine fish communities and fisheries, but there is little information on their age and growth or age validation. This study validated the periodicity of growth...
  3. Invasion of a headwater stream by non-native fishes in the Swartkops River system, South Africa

    Invasion of a headwater stream by non-native fishes in the Swartkops River system, South Africa

    Item type: Journal Article • Journal: African Zoology
    In South Africa, fishes in headwater streams are increasingly being threatened by non-native fish invasions. These invasions originate primarily from source populations in mainstream rivers and impoundments. In the Blindekloof stream, a Swartkops River headwater tributary, the non-native Micropterus salmoides...
  4. Life history strategy and population characteristics of an unexploited riverine cyprinid, <em>Labeo capensis</em>, in the largest impoundment in the Orange River Basin

    Life history strategy and population characteristics of an unexploited riverine cyprinid, <em>Labeo capensis</em>, in the largest impoundment in the Orange River Basin

    Item type: Journal Article • Journal: African Zoology
    The life history of an endemic riverine African cyprinid, Labeo capensis, that dominates the larger ichthyofauna in a large impoundment in the Orange River Basin four decades after damming, was investigated. Both sexes grew at a similar rate until the...
  5. Juvenile population dynamics of <em>Oreochromis mossambicus</em> in an intermittently open estuary at the limit of its natural distribution

    Juvenile population dynamics of <em>Oreochromis mossambicus</em> in an intermittently open estuary at the limit of its natural distribution

    Item type: Journal Article • Journal: African Zoology
    Juvenile Oreochromis mossambicus in the 25 ha, temperate, intermittently open, East Kleinemonde Estuary in the Eastern Cape, South Africa (33°32’S, 27°03’E), showed a seasonal shift in distribution, occupying all areas of the estuary in summer and, subsequently, being limited to...
  6. Validation of growth zone deposition in otoliths of two large endemic cyprinids in Lake Gariep, South Africa

    Validation of growth zone deposition in otoliths of two large endemic cyprinids in Lake Gariep, South Africa

    Item type: Journal Article • Journal: African Zoology
    We tested the hypothesis that growth zones in the astericus otoliths of smallmouth yellowfish (Labeobarbus aeneus) and Orange River mudfish (Labeo capensis) were deposited annually. Two methods, fluorochrome marking and edge analysis of otoliths were used. For fluorochrome marking, specimens...
