Abstract

An account is given of the aquatic gastropod molluscs obtained in a survey made to assess future ecological effects of the Jonglei Canal now under construction in the Sudd region of southern Sudan. A total of about 23 species of aquatic snail lives in this region, of which a number are utilised as intermediate hosts by trematode parasites infecting man, livestock and wild herbivores, causing the diseases schistosomiasis, fascioliasis and amphistomiasis. Public health and veterinary authorities should be alert to the possibility that the Jonglei Canal will increase snail populations and raise the prevalence of parasitic diseases.
