title: [Diplostomiasis in fishes in lake farms and the ways for its control].
abstract: Diplostomosis is the most common disease affecting Coregonidae in lakes of Karelia where intensive fish farming is conducted. The most acute form of diplostomosis, cercariosis, is especially dangerous for larvae introduced into small water bodies. Depending on a season or weather conditions a shift in the infection rate of fishes with metacercariae takes place. Some ways for diplostomatosis prophylaxis are being suggested. Relatively shallow lakes with low miniralisation of water of sulphate type have been found to be most suitable for Coregonidae nurseries. The very specificity of the intensive use of lakes for fish farming offers possibilities for diplostomosis development. In lakes-nurseries with a regulated water regime the abundance of Lymnaeidae can be reduced by winter draining off the water. The chemical control of mollusks, local use of copper sulphate, is also possible under lake conditions.
