The phototactic behaviour of cercariae was used as the basis of a technique in which cercariae were induced to migrate into a layer of clear water overlying the turbid sample; the clear layer was then filtered and the cercariae counted. The recovery rate, however, does not appear to justify the use of this technique, at least in the field.}, keywords = {*Schistosoma mansoni, Animals, Evaluation Studies as Topic, Larva, methods, Photic Stimulation, water}, isbn = {0042-9686 (Print)
