Quantitative aspects of the spionid polychaete Pygospio elegans population in the Polish coastal zone of the Baltic Sea, in estuarine areas of Pomeranian river mouths were investigated. The fre-quency of occurrence (F) of P. elegans in the Polish coastal zone averaged 54% (permanent spe-cies) and ranged from 20 to 80%. The polychaete abundance along the Central Pomeranian coast peaked at 1 837 ind. m-2, the mean abundance being 175.7 ind. m-2. The density of the spionid worm in the Middle Pomerania was low and rarely exceeded 1 000 ind. m-2. The mean wet weight biomass of P. elegans in different areas was low (max. 0.29 gww m-2). The abundance of P. elegans in the river mouth areas (estuaries) was basically higher west of the mouth, in areas less exposed to polluted and freshened riverine water; water in those areas, however, carried lower bioseston loads, which affected trophic conditions.
