ABSTRACT. Common carp and ide were reared in polyculture from March to October 1995, in the Fish Farm Ostróda-Warlity. The fish ponds were supplied with water from Lake Szeląg Wielki (599 ha) classified as vendace-type lake. Microbiological studies of pond water and bottom sediments and of lake water were carried out during fish rearing. Bacterial contamination, sanitary state of water, nitrogen-transforming microorganisms and fungi were studied at the background of thermal conditions, DO content and zooplankton abundance in the ponds.
