Sobecka E., Pilecka-Rapacz M. Pseudodactylogyrus anguillae (Yin et Sproston, 1948) Gussev, 1965 and P. bini (Kikuchi, 1929) Gussev, 1965 (Monogenea: Pseudodactylogyridae) on gills of European eel, Anguilla anguilla (Linnaeus, 1758) ascending rivers of the Pomeranian coast, Poland. Acta Ichthyol. Piscat. 33 (2): 137-144
Background. Monogenean parasites Pseudodactylogyrus anguillae and P.bini were for the first time recorded on eel in 1995. The aim of the present study was to determine their distribution in Poland and to verify their measurements against literature data.
Materials and methods. A total of 201 young eels ascending rivers of Polish Western Pomerania, emptying to the Baltic Sea, were collected and necropsied using commonly used methods.
Results. Altogether, 574 monogeneans were found on the gills of the eels studied, of which P. anguillae constituted 82%. Measurements of hard elements of the two species of parasites were similar to those already described from Poland.
Conclusion. The present paper constitutes a new record of Pseudodactylogyrus anguillae and P. bini, supported by measurements.
