摘要:

During an investigation of the life history ofTriaenophorus crassusat Lesser Slave Lake it was found that the coracidia could be killed by increasing the acidity of their laboratory cultures to pH 5.0. In May, 1945, an experiment was carried out at Baptiste Lake, Alta., to determine whether the coracidia could be killed in the lake by acidifying the lake water with sulphuric acid. The experiment was a failure; the value of the work lies in the demonstration of the method used to assess the effects of the treatment.
