Abstract

Lake Balaton, a shallow lake, is located in the western part of Hungary. The water surface is 596 km2 with an average depth of 3.2 m. The dominant ions in the water are Ca, Mg, and HCO3. The average pH is 8.3. Apart from some publications, the role of the stony shores covering 70-75% of Lake Balaton's littoral zone (the whole shoreline is 193 km) has not yet been studied completely. Ten sampling sites were selected in Lake Balaton's four basins of different water qualities: in Keszthely Basin, in Szigliget Bay, at the Balaton Limnological Research Institute of the HAS in the middle basin, and in Fu{double acute}zfo{double acute} Bay. The changing compositions of zootecton were studied, which was influenced by the weather and water supply. For example, in 2003 the low water level was characteristic for the lake. The taxonomic composition, the situation, and the substrate features given of the littoral zone have an outstanding role in the life of Lake Balaton, because this zone provides food resources and nesting habitats for waterbirds. We also found that the filtering in 2003, in 2004, and in 2005 as well, the predacious zoo-organisms were found in the largest number in the zootecton.
