  1. Simultaneous extraction of chitin and astaxanthin from waste of lobsters <em>Jasus lalandii</em>, and use of astaxanthin as an aquacultural feed additive

    Simultaneous extraction of chitin and astaxanthin from waste of lobsters Jasus lalandii, and use of astaxanthin as an aquacultural feed additive

    Item type: Journal Article • Journal: African Journal of Marine Science • Authors: L Auerswald G Gäde
    This work investigates simple methods for simultaneous extraction of astaxanthin and chitin from industrial waste of the South African West Coast rock lobster Jasus lalandii. Removal of proteins from waste is the critical step to yield intact chitin and astaxanthin...
  2. 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 Palaemon peringueyi (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 • Authors: NP Nyalungu --- South African National Parks, Cape Research Centre, South Africa AN Hodgson --- Department of Zoology and Entomology, South Africa PW Froneman --- Department of Zoology and Entomology, South Africa M Dopolo --- South African National Parks, Cape Research Centre, South Africa M Masubelele --- South African National Parks, Cape Research Centre, South Africa
    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...
  3. Toxicity evaluation of effluent from the de-oiling works of a decommissioned Nigerian crude oil pipeline using <em>Palaemonetes africanus</em>

    Toxicity evaluation of effluent from the de-oiling works of a decommissioned Nigerian crude oil pipeline using Palaemonetes africanus

    Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: NH Amaeze --- Ecotoxicology Laboratory, Department of Zoology, Nigeria FA Adetoro --- Ecotoxicology Laboratory, Department of Zoology, Nigeria OA Adegboro --- Ecotoxicology Laboratory, Department of Zoology, Nigeria
    Oil industry activities often involve the cleaning and replacement of pipelines, usually resulting in the discharge of effluents into waterbodies. The toxicity of de-oiling effluent from a decommissioned crude oil pipeline in the Niger Delta region of Nigeria was assessed...
  4. A tale of records from Hakskeen Pan, the first record of <em>Pumilibranchipus deserti</em> Hamer and Brendonck, 1995 (Anostraca, Branchiopoda) from South Africa and the pursuit of a new world land speed record

    A tale of records from Hakskeen Pan, the first record of Pumilibranchipus deserti Hamer and Brendonck, 1995 (Anostraca, Branchiopoda) from South Africa and the pursuit of a new world land speed record

    Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: E Meyer-Milne --- South African Environmental Observation Network, South Africa MC Mlambo --- Department of Freshwater Invertebrates, Albany Museum, South Africa
    Until now, Pumilibranchipus deserti was known from only one locality in Namibia. This paper reports the first record of this species from South Africa in Hakskeen Pan, Northern Cape, which represents a new, easterly range extension of the known distribution...
