  1. THE EFFECT OF CONSTANT TEMPERATURES ON THE HATCHING OF EGGS AND SURVIVAL OF THE FRESHWATER SNAIL <em>BIOMPHALARIA GLABRATA</em> (SAY)

    THE EFFECT OF CONSTANT TEMPERATURES ON THE HATCHING OF EGGS AND SURVIVAL OF THE FRESHWATER SNAIL <em>BIOMPHALARIA GLABRATA</em> (SAY)

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    The incubation period and percentage hatching of eggs of pigmented and unpigmented Biomphalaria glabrata at constant temperatures were investigated in the range 14 °C to 34 °C. In order to determine the influence of extreme temperatures on adult snails, specimens...
  2. AN EVALUATION OF BABY FISH FOOD AS A SUITABLE DIET FOR THE FRESHWATER SNAIL, <em>BIOMPHALABIA GLABRATA</em> (SAY)

    AN EVALUATION OF BABY FISH FOOD AS A SUITABLE DIET FOR THE FRESHWATER SNAIL, <em>BIOMPHALABIA GLABRATA</em> (SAY)

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa
    Tetra Kin Baby Fish Food ‘E’ for Egglayers (Tetra ‘E’) was evaluated as a possible nutrient for the laboratory culture and maintenance of pigmented and unpigmented Biomphalaria glabrata (Say). Growth was monitored weekly by determining shell diameter and mass. The...
  3. Benthic macrofauna community composition, abundance and distribution in the Tanzanian and Ugandan inshore and offshore waters of Lake Victoria

    Benthic macrofauna community composition, abundance and distribution in the Tanzanian and Ugandan inshore and offshore waters of Lake Victoria

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Benthic macroinvertebrate community composition was investigated in 2008 at 55 stations at various depths in the nearshore and offshore waters of Lake Victoria, in relation to dissolved oxygen, pH, temperature, chlorophyll a and conductivity. Macroinvertebrate abundance was higher in the...
  4. A laboratory assessment of the potential molluscicidal activity of some Nigerian plant species used as anthelmintics

    A laboratory assessment of the potential molluscicidal activity of some Nigerian plant species used as anthelmintics

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Laboratory studies were conducted to determine the potential molluscicidal activity of five Nigerian plant species used in alternative medicine practice as anthelmintics. Laboratory-bred adult Biomphalaria pfeifferi, the snail host of Schistosoma mansoni in Nigeria, and their viable 0- to 24-hour-old...
  5. A laboratory assessment of the potential molluscicidal potency of <em>Jatropha curcas</em> aqueous extracts

    A laboratory assessment of the potential molluscicidal potency of <em>Jatropha curcas</em> aqueous extracts

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Preliminary laboratory studies were conducted to determine the molluscicidal potency of Jatropha curcas, the physic nut. Biomphalaria glabrata and Bulinus globosus snails were exposed to varying concentrations of aqueous extracts of crushed J. curcas seeds from unripe, ripe and overripe...
  6. The Mollusca inhabiting rice fields in northern Cameroon and their role as intermediate hosts for schistosomes

    The Mollusca inhabiting rice fields in northern Cameroon and their role as intermediate hosts for schistosomes

    Item type: Journal Article • Journal: African Zoology
    A systematic account is given of the freshwater gastropod and bivalve fauna of Ouro-Doukoudje, northern Cameroon, based on a survey conducted from July 2000 to June 2001 at 12 sites in rice fields spanning 800 ha. In total, 14 species...
  7. Sympatric <em>Biomphalaria</em> species (Gastropoda: Planorbidae) in Lake Albert, Uganda, show homoplasies in shell morphology

    Sympatric <em>Biomphalaria</em> species (Gastropoda: Planorbidae) in Lake Albert, Uganda, show homoplasies in shell morphology

    Item type: Journal Article • Journal: African Zoology
    The three known sympatric Biomphalaria species that occur in Lake Albert; B. choanomphala, B. stanleyi and B. sudanica, were studied using both molecular (COI, 16S and ITS) and shell morphometric data. An unidentified sample of 18 Biomphalaria specimens from Lake...
