METAZOAN PARASITES OF FISH FROM THE ŁEBSKO LAGOON (CENTRAL COAST, POLAND)
Journal Title: Baltic Coastal Zone - Year 2007, Vol 11, Issue 1
Abstract
Throughout 3 years, a total of 721 various fish species, from the Łebsko Lagoon were examined. The most abundant groups of parasites were Digenea and Crustacea. Metacercariae of Posthodiplostomum cuticola (Nordmann, 1832) were found only in Cyprinidae (highest prevalence in rudd – 62.5%, and mean intensity in roach 12.71 indiv.). Metacercariae of Diplostomum spp. and Tylodelphys clavata (Nordmann, 1832), and also copepods Ergasilus sieboldi Nordmann, 1832 occurred in majority of examined fish species. The highest infection with Diplostomum spp. was noted in rudd (prev. 50.0%, int. 11.25 indiv.). T. clavata occurred with highest prevalence in pike (46.15%) and mean intensity amounted to 54.7 indiv. in perch. E. sieboldi was reported mostly from zander with typical for this fish Achtheres percarum (Nordmann, 1832) (prev. 75.0% and 92.86%; int. 6.0 indiv. and 10.92 indiv. respectively). Also nematode [i]Anguillicola crassus[/i] was noted with high prevalence 76.47% in eel. The remaining parasites species were noted less frequently.
