THE INDICES OF SPECIFIC DAILY PRODUCTION (P/B INDICES) FOR ESTIMATION OF PRODUCTION OF SOME HYDROBIOLOGICAL COMMUNITIES IN STREAMS AND FRESH RESERVOIRS
The analysis of literature data of hydrobilogical investigations in fresh reservoirs and rivers of Belarus and analogous climatic regions carried out. It makes possible to determine approximate indexes of specific daily production (P/B indices) in Belarus region for individual species, biological communities of Rotifera, Cladocera, Copepoda, Chironomidae, Mollusca, Oligochaeta, Amphipoda and larvae of second time water species.
