Community of phytophilous macrozoobenthos (PM) represents an important component of fishponds ecosystems concerning biomass as well as essential part of food webs. There are evident linkages between PM and water macrophytes. Their influence on PM is the main topic of many scientific papers which state three main water macrophyte characters with the strongest impact on PM - coverage, biomass and morphological complexity. The main aim of this diploma theses was to analyse linkages between four different water macrophyte species and PM in eight different fishponds devided into two groups according their localisation- třeboňské a rakouské. Water macrophyte species have any influence on PM abundance in both fishpond groups. Water macrophyte species have significant influence on biomass of PM in třeboňské and rakouské fishponds analysed together and also in both fishpond groups analysed separately. PM biomass was significantly higher in Glyceria maxima during first sampling period in both fishpond groups. Water macrophyte species have significant influence on PM diversity in třeboňské and rakouské fishponds analysed together and in rakouské fishponds group analysed separately. Just one variable, water macrophyte species, was analysed in my diploma thesis, but some others abiotic and biotic variables influence phytophilous macrozoobenthos community in fishponds littoral zones as well. That´s why conclusions of this thesis should be interpreted circumspectly.
