    Louisiana crayfish (<em>Procambarus clarkii</em>) (Crustacea: Cambaridae) in Kenyan ponds: non-target effects of a potential biological control agent for schistosomiasis

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The Louisiana crayfish (Procambarus clarkii) has been proposed as a biological control agent for the intermediate snail hosts (Bulinus and Biomphalaria spp.) of human schistosomes (Schistosoma haematobium and S. mansoni) in Kenya. Using laboratory and field experiments, we examined the...
  2. Comparing macrophyte herbivory by introduced Louisiana crayfish (<em>Procambarus clarkii</em>) (Crustacea: Cambaridae) and native Dytiscid beetles (<em>Cybister tripunctatus</em>) (Coleoptera: Dytiscidae), in Kenya

    Comparing macrophyte herbivory by introduced Louisiana crayfish (<em>Procambarus clarkii</em>) (Crustacea: Cambaridae) and native Dytiscid beetles (<em>Cybister tripunctatus</em>) (Coleoptera: Dytiscidae), in Kenya

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The omnivorous Louisiana crayfish, Procambarus clarkii, has caused significant changes to macrophyte communities worldwide and may have similar negative effects in Kenya if used as a biological control agent for snails harbouring human schistosomes. Here we examine how herbivory by...
  3. Growth patterns of the pearl oyster <em>Pinctada margaritifera</em> L. in Gazi Bay, Kenya

    Growth patterns of the pearl oyster <em>Pinctada margaritifera</em> L. in Gazi Bay, Kenya

    Item type: Journal Article • Journal: African Journal of Marine Science
    Culture of pearl oysters is rapidly increasing worldwide, including the western Indian Ocean. The oyster Pinctada margaritifera L., which produces the most highly valued black pearls, occurs in East Africa, a nd as been exploited there for the shell for...
  4. Size at onset of maturity of spiny lobsters <em>Panulirus homarus homarus</em> at Mambrui, Kenya

    Size at onset of maturity of spiny lobsters <em>Panulirus homarus homarus</em> at Mambrui, Kenya

    Item type: Journal Article • Journal: African Journal of Marine Science
    The size at onset of sexual maturity of the scalloped spiny lobster Panulirus homarus homarus captured off Mambrui, Kenya, was estimated from ovary condition, presence of external eggs and/or spermatophore remains (berry method), and presence of well developed ovigerous setae...
