In the conditions of the Republic of Belarus there was presented structure of ichthyocoenosis (fish communities) and occurrence of fish species in lakes. There was analysed frequency of paired occurrence and dependence of ichthyocoenosis density on some limnological traits. In course of the study there were presented and analysed the following statistical data: occurrence of certain fish species in the analysed water ponds (depending on lake area and on the genetic type of a lake); comparative occurrence of the analysed fish species in lakes of different European regions (Belarus; Lithuania; Estonia; Leningrad region of the Russian Federation; Vologograd region of the Russian Federation; Sweden); frequency of paired occurrence of fish species in Belarusian lakes; dependence of probability of occurrence of fish species on ichthyocoenosis density. Also there were analysed data of correlation between ichthyocoenosis density and limnological traits of small lakes; dependence of ichthyocoenosis density on the area of water line; dependence of ichthyocoenosis density on a genetic type of a lake; dependence of ichthyocoenosis density on a group of pond according to a fishery classification.
