Aspekte van die respirasiefisiologie van Biomphalaria glabrata (Say)
(North-West University (South Africa), 1987)Various aspects concerning the respiration physiology of the snail, Biomphalaria glabrata were investigated. The metabolic rate of Biomphalaria glabrata was determined by measuring the rate of oxygen consumption in ... -

Die assimilering van chlorella spp. deur twee varswaterslakspesies
(North-West University (South Africa), 1979)The assimilation of the alga Chlorella by the freshwater snails Buli nus (Physopsis) africanus (Krauss) and Bulinus (Bulinus) tropicus (Krauss) was investigated. Algae, collected from the snails' habitat were cultured ... -
Die effek van lood en waterkwaliteit op die biologie van die vleikurper, Tilapia Sparrmanii
(North-West University (South Africa), 2001)1. Handling stress increases the oxygen consumption rate (M02) of Tilapia sparrmanii by an average of27% and stabilises four hours after handling. 2. All M02 measurements were done after a ten hour rest period. 3. For ... -
Die invloed van kopersulfaat op die ioon- en waterbalans van Bulinus [Bulinus] Tropicus [Krauss]
(North-West University (South Africa), 1976)A quantitive study of the influence of coppersulphate on the ion and water balance of Bulinus (Bulinus) tropicus (Krauss) has been undertaken. Laboratory reared snails and snails collected in the field have been used ... -

Die opname en verspreiding van kopersulfaat by die varswaterslak Bulinus (Bulinus) Tropicus
(North-West University (South Africa), 1984)THE UPTAKE AND DISTRIBUTION OF COPPER SULPHATE BY THE FRESHWATER SNAIL BULINUS (BULINUS) TROPICUS The copper concentration found in the haemolymph, shell and the whole snail was determined by atomic absorption ... -
Fisiologiese aspekte van anhidrobiese by die varswaterslak Bulinus [Bulinus] tropicus [Krauss]
(North-West University (South Africa), 1974)Certain physiological aspects of Bulinus (Bulinus) tropicus (Krauss), a member of the freshwater pulmonates, in a waterless environment have been studied. To escape severe drought in their natural habitat, these snails ... -
A methodology for undertaking freshwater fish chemical contaminant surveys for human health risk assessment
(Potchefstroom University for Christian Higher Education, 2000)In South Africa the pollution of freshwater aquatic systems can be linked to point source discharges (waste water treatment works and industrial effluents) and diffuse surface runoff (agricultural, mining and urban). As a ... -
