Popis: Biomphalaria pfeifferi, the snail intermediate host of Schistosoma mansoni was cultured in the laboratory to show the effects of calcilllll chloride (CaC12) on its growth rate and survival. Ten snails of approximately the same size and age were cultured in each of 4 tanks set up. In 3 of the tanks, CaC1 2 was dissolved in 1000 rnL of water in various concentrations. The 4th tank served as control experiment where snails were bred without any CaC1 2 added. Highest growth rate was recorded in tank with highest concentration but percentage rate of survival was lowest here. Lowest growth was recorded in the control tank. Highest survival rate was recorded in tank 1 where calcium concentration was lowest. Significant increase in growth (p
