This study concerns the distribution of nereid Hediste diversicolor in the Middle Pomerania, near the estuaries of five rivers (Parsęta, Wieprza, Słupia, Łupawa and Łeba). The highest density of Hediste was observed in the vicinity of the Wieprza estuary while the lowest (7-fold lower) in the estuary of the Łeba River. As for biomass, it was the highest in the river mouth of Parsęta and the lowest in the Wieprza estuary. Frequency in the studied estuaries was low and amounted to 32%. Using standard statistical methods (significance tests) we indicated differences in average Hediste density and biomass between the eastern and western transects. Nereid’s density was 2-fold higher in the eastern transects while biomass in western. The applied multivariate regression and classification tree method (MR&CT) revealed that the density of Hediste was determined only by the depth of a sampling site while biomass by the distance from the coast. The Spearman’s correlation coefficient analysis indicated significant (p < 0.05) dependence of biomass and density on depth and distance from the shore. Due to ecological role of H.diversicolor as a food source for benthivorous fish, including valuable and endangered species (cod, flatfish), the analysis of food supply can be important in the identification of fish feeding grounds.
