Predation on snails by an indigenous fish, Sargochromis codringtonii, in ponds in Zimbabwe
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: MJ Chimbari H MadsenThe extent to which Sargochromis codringtonii (a known predator of snails) can control snail numbers was investigated in cementlined ponds in order further to evaluate the fish's potential as an agent for the biological control of fresh water snails, especially... -
Schistosomiasis transmission in Lake Malawi
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: HR Madsen JR Stauffer P Bloch A Konings KR McKaye JS LikongweSchistosomiasis (bilharziasis) transmission due to Schistosoma haematobium has for many years been known to occur along protected shorelines in Lake Malawi, but the recent finding that transmission also can also occur along open shorelines with sandy sediment has had a... -
Interactions between fish and snails in a Zimbabwe pond, with particular reference to Sargochromis codringtonii (Pisces: Cichlidae)
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: Paul Makoni MosesJ Chimbari Henry MadsenThe impact of fishes on snail densities in a 100 x 12m pond was assessed from October 2000 to May 2002, using a fish exclosure experiment. Snail species included numerically dominant Bulinus globosus (ca 85%) as well as B. tropicus,... -
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 • Authors: GW Ngupula --- , Tanzania R Kayanda --- , TanzaniaBenthic 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... -
A laboratory assessment of the potential molluscicidal potency of Jatropha curcas aqueous extracts
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: MJ Chimbari CJ ShiffPreliminary 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... -
Micro-distribution of freshwater snails before and after water flow events in hydraulic structures in Tessaout Amont irrigation system, Morocco
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: H Laamrani H Madsen E BoeleeBulinus truncatus, the intermediate host of Schistosoma haematobium, is widely distributed in modern irrigation schemes in Morocco. These schemes have intermittent irrigation and canals dry out in between irrigation periods. The snail species is therefore associated with the 'siphon boxes'... -
The Mollusca inhabiting rice fields in northern Cameroon and their role as intermediate hosts for schistosomes
Item type: Journal Article • Journal: African Zoology • Authors: A. Ndassa --- General Biology Laboratory, Faculty of Science, Cameroon R. Mimpfoundi --- General Biology Laboratory, Faculty of Science, CameroonA 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... -
Preliminary study on the culture and breeding of Bulinus nyassanus (Mollusca: Pulmonata) under laboratory conditions
Item type: Journal Article • Journal: African Zoology • Authors: Mary Lundeba --- Aquaculture and Fisheries Science Department, Malawi Jeremy S. Likongwe --- Aquaculture and Fisheries Science Department, Malawi Henry Madsen --- DBL Institute for Health Research and Developmemnt, Denmark Jay R. Stauffer --- School of Forest Resources, Penn State University, U.S.A.We successfully artificially cultured and bred Bulinus nyassanus, endemic to Lake Malawi and an intermediate host of Schistosoma haematobium. The laboratory culture of this snail species is essential in relation to further experiments on the feasibility of using facultative snail-eating... -
Morphological studies on Bulinus sp. (Gastropoda: Planorbidae) from Nchout Monoun, Cameroon
Item type: Journal Article • Journal: African Zoology • Authors: R. Mimpfoundi --- General Biology Laboratory, Faculty of Science, Cameroon A. Ndassa --- General Biology Laboratory, Faculty of Science, CameroonSince 1990, diploid Bulinus sp. populations have been reported from many sites in the volcanic western Bamileke and Bamoun plateau in Cameroon; starch gel electrophoresis of enzymes and chromosome analyses have revealed a single band in hydroxybutyrate dehydrogenase (HBDH), isocitrate... -
Potential of Metriaclima lanisticola (Teleostei: Cichlidae) for biological control of schistosome intermediate host snails
Item type: Journal Article • Journal: African Zoology • Authors: Mary Lundeba --- Aquaculture and Fisheries Science Department, Malawi Jeremy S. Likongwe --- Aquaculture and Fisheries Science Department, Malawi Henry Madsen --- DBL Center for Health Research and Development, Denmark Jay R. Stauffer --- School of Forest Resources, Penn State University, U.S.A.Metriaclima lanisticola, a native cichlid of Lake Malawi, was studied under laboratory conditions to evaluate its possible role as a predator of snails (Bulinus spp.). Bulinus globosus, B. nyassanus and B. tropicus were used as prey. B. globosus and B... -
Geographical distribution and habitats of the freshwater snail Bulinus reticulatus and its susceptibility to Schistosoma haematobium miracidia under experimental conditions
