RÉSUMÉ

Successions of bacterioplankton registered in Lake Wamiak (Poland) in 1996-1999 were related to changes in its ecosystem conditioned by biomanipulation measures carried out previously. Secondary intensive development of hydrophytes in the littoral zone of the lake was responsible for stabilization of bottom sediments, and also for a decrease in their role in the formation of bacterioplankton. At the same time, the activity of the processes of bacterial decomposition of organic matter remained unchanged.
