  1. A histological description of ovarian recrudescence in two <em>Labeo victorianus</em> populations

    A histological description of ovarian recrudescence in two <em>Labeo victorianus</em> populations

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The ovaries of Labeo victorianus are paired organs situated in the peritoneal cavity and suspended on either side of the midline by a mesovarium. A capsule, composed of dense, regularly-arranged collagen and elastic fibres mixed with a few smooth muscle...
  2. Differentiated gonochorism in Nile perch <em>Lates niloticus</em> from Lake Victoria, Uganda

    Differentiated gonochorism in Nile perch <em>Lates niloticus</em> from Lake Victoria, Uganda

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Gonadal development and structure were examined in 317 Nile perch, Lates niloticus, of 4 to 157 cm SL taken from Lake Victoria, Uganda, in 2005–2006. Macroscopic and histological investigation showed a differentiated gonochoristic pattern, with no juvenile intersexuality. Oogonial cells...

    Reproduction in the viviparous South African clinid fish <em>Fucomimus mus</em>

    Item type: Journal Article • Journal: African Journal of Marine Science
    Description of the reproductive anatomy, histology and seasonality of reproduction of the viviparous clinid fish, Fucomimus mus, was based on a collection of 227 specimens from various intertidal localities off the south-east coast of South Africa. Males produce sperm throughout...
  4. Annual variation of ovarian structures of <em>Boulengerula taitana</em> (Loveridge 1935), a Kenyan caecilian

    Annual variation of ovarian structures of <em>Boulengerula taitana</em> (Loveridge 1935), a Kenyan caecilian

    Item type: Journal Article • Journal: African Journal of Herpetology
    The Kenyan caecilian, Boulengerula taitanus inhabits a climate characterised by two distinct dry and wet seasons, and a single thermal minimum in June. It is oviparous with direct development and a remarkable dermatophagous maternal care, but the female reproductive cycle...
  5. Describing gonad development and gametogenesis in southern Africa’s endemic box jellyfish <em>Carybdea branchi</em> (Cubozoa, Carybdeidae)

    Describing gonad development and gametogenesis in southern Africa’s endemic box jellyfish <em>Carybdea branchi</em> (Cubozoa, Carybdeidae)

    Item type: Journal Article • Journal: African Journal of Marine Science
    Information on the reproductive development of species of box jellyfish (class Cubozoa) is poor globally, despite their significance as potent stingers and worrying projections about range expansions. While most species are confined to tropical and subtropical waters, the South African...
