title: [Intestinal digeneans of Gavia stellata (Pontoppidan, 1763) and Gavia arctica (Linnaeus, 1758) from West Pomerania, Poland].
abstract: In 2000 and 2006 a total of 20 divers including 15 Gavia stellata and 5 Gavia artica from Pomeranian Bay and Szczecin Lagoon were examined. G. stellata were found to be infected with 3 digenean species: Stephanoprora pseudoechinata (Olsson, 1876), Cryptocotyle concava (Creplin, 1825) and Diplostomum gavium (Guberlet, 1922). G. arctica were host to Echinochasmus spinulosus (Rudolphi, 1809). This is the first record of Stephanoprora pseudoechinata in G. stellata and Echinochasmus spinulosus in G. arctica in Poland. The prevalence of S. pseudoechinata infection (46.7%) was higher than that of other digeneans.
