The aim of the present study was to describe and to compare the varying Chironomus population dynamics and the diverse population density and to find out factors and mechanisms causing various population levels and dynamics. It was based on long-term series of data and also on the results of previous experiments. The main correlation between Chironomus and Tubificidae abundance is the increase of abundance of the latter probably due to the "manuring" of the environment by abundantly dying Chironomus larvae
