Parasitofauna of the nine-spined stickleback from the Gulf of Gdansk and the mouth of Dead Vistula

Four species, one subspecies and one parasite marked to the genus were collected from the nine-spined stickleback Pungitius pungitius L. from the Gulf of Gdańsk and the mouth of Dead Vistula. Nine - spined stickleback was noted as a new host in Polish coastal water for five parasites: Glugea anomala (Microsporidia), Diplostomum spathaceum (Digenea – metacercariae) and Apatemon sp. (Digenea - incysted metacercariae), Hysterothylacium aduncum (Nematoda - third stage larvae) and Thersitina gasterostci (Copepoda). Earlier in this area have been obserwed only ciliates Tnchodina domerguei.
