Type of object: Subject and Keywords: Abstract:Very high increase of benthos biomass (total biomass – 18 times, biomass of Chironomidae – more than 70 times) occurred in enclosures where plankton was exploited using plankton nets. The assumed cause was the change in planktonic community and resulting better food conditions for benthos. In all other experimental variants (protection from fish, addition of food, artificial oxygen deficit, stirring of mud) changes in benthos were much smaller.
