A detailed temporal and spatial analysis on the heterotrophic and total bacterioplankton was carried out in the shallow Lake Balaton. Significant daily, seasonal and yearly fluctuations have been found in the number, biomass and production of the bacterioplankton. The vertical distribution is unstable except the stratification under ice. A definite differentiation have been found between the littoral zone and the open water. Depending on the self-purification capacity of lake water, the river influence was different seasonaly. The most important trend in modern limnology is to quantify the basic energy sources and the main pathways and transfer efficiencies of energy in aquatic ecosystems. Sufficient data enable us to construct cybernetical models in order to describe the dynamic structure and function of ecosystems. Bacterial function results in the decomposition of organic matter and in the production of bacterial protein in the biosynthetic processes. This particulate bacterial protein serves as a basic food resource for the nutrition of aquatic animals.
