Abstract
Changes in the dominance structure of zooplankton in the River Odra estuary were studied over the years 1984-1988; samples were collected 4 times a year. Frequency distribution analysis of dominants and subdominants was carried out to outline a hypothetical pattern of succession in the area of study. The following filtrators were found to mainly influence the spatial structure of the zooplankton: Daphnia cucullata, Bosmina coregoni and Bosmina coregoni maritima, the advanced eutrophication of the estuary resulting in abundant food resources in the form of phytoplankton.
