Hydrobiology, zoo-monitoring of lakes and currents, taxonomy and ecology of Crustacea

Current survey primarily involves streams and currents flowing into Lake Balaton and the hot spring lake in Hévíz. Research has a double purpose: 

1) Revealing of the yet unknown or hardly known fauna and 

2) working out the zoo-monitoring system as well as the registration of ecological changes occurring in the water bodies.
