    Development of acoustic techniques for assessment of orange roughy <em>Hoplostethus atlanticus</em> biomass off Namibia, and of methods for correcting for bias

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Orange roughy form dense spawning aggregations in specific small areas in deep water on the Namibian shelf between late June and early August each year. The biomass in three such areas, where most commercial fishing occurs (the Johnies, Frankies and...
  2. Evapotranspiration, water‐use efficiency and quality of six dryland planted pasture species and natural vegetation, in a semi‐arid rangeland<sup>1</sup>

    Evapotranspiration, water‐use efficiency and quality of six dryland planted pasture species and natural vegetation, in a semi‐arid rangeland<sup>1</sup>

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Hydraulic, non‐floating lysimeters were used to determine evapotranspiration (Et) and water‐use efficiency (WUE) of several dryland planted pasture species over a period of three years. The species were Anthephora pubescens, Cenchrus ciliaris, Chloris gayana, Digitaria eriantha subsp. eriantha, Eragrosiis curvula...
