Abstract: In blood fluke(Schistosoma) susceptible regions of the lake beach,experiments of water inundated elimi-nating snail(Oncomelania) are carried out by building low dikes for retaining water. The results show that mortalities of living snail and snail eggs are 100% when they are inundated in water for 11-22 months.
