  1. Stage-dependent vertical distribution of pelagic fish eggs on the western Agulhas Bank, South Africa

    Stage-dependent vertical distribution of pelagic fish eggs on the western Agulhas Bank, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    The vertical distributions of eggs of anchovy Engraulis encrasicolus, sardine Sardinops sagax and round herring Etrumeus whiteheadi over the western Agulhas Bank, South Africa, were sampled between 0m and 100m, using an opening-closing WP-2 net, to investigate differences in developmental...
  2. Fine-scale spatial variability of different stages of pelagic fish eggs over the western Agulhas Bank, South Africa

    Fine-scale spatial variability of different stages of pelagic fish eggs over the western Agulhas Bank, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Stage-dependent spatial distributions of anchovy Engraulis encrasicolus, sardine Sardinops sagax and round herring Etrumeus whiteheadi eggs over the western Agulhas Bank South Africa were examined from samples collected at a fine-scale (1.8 km) resolution using a continuous underway fish egg...
  3. Temporal and spatial variability in the abundance, biomass and distribution of <em>Palaemon peringueyi</em> (Decapoda: Crustacea) are influenced by biological but not physico-chemical factors in the permanently open Kariega Estuary, South Africa

    Temporal and spatial variability in the abundance, biomass and distribution of <em>Palaemon peringueyi</em> (Decapoda: Crustacea) are influenced by biological but not physico-chemical factors in the permanently open Kariega Estuary, South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Biological and physico-chemical factors affecting abundance and biomass of shrimp Palaemon peringueyi were investigated in 2010–2011 in the lower, middle and upper reaches of the freshwater-deprived permanently open Kariega Estuary. Shrimp abundance and biomass ranged from 0 to 88 ind...
