Abstract
The algorithm of dynamic mass-balance simulating a biotic energy flow in planktonic community containing the microbial organisms has been developed. Inlet parameters of the model are latitude, mean depth of the water body, total phosphorus content and water colour. Biomass and production of the key plankton group are predicted by the model. It is shown that a food base for fish and fish growth depend on extent of protozoan plankton contained in food web.
