Rotifer and crustacean ecological groups, distinctive of low-trophic-state lakes and eutrophic lakes have been identified. Zooplankton specific composition changes accompanying lake eutrophication occur in steps, over a narrow TSISD (45 -55) range. An increasing dominance of small-bodied species must be looked at as the cause of differences in the response of numbers and biomass to a rising trophic state – a rising trophic state is accompanied by a diminishing of the biomass to numbers (B: N) ratio of the rotifers and crustaceans. On the basis of a statistical analysis a selection has been made of structural characteristics of high bioindicative values, most useful in ecological monitoring.
