Aquaculture as a possible vector in the spread of Posthodiplostomum centrarchi (Hoffman, 1958) (Digenea: Diplostomidae) in Europe.
This study presents findings on metacercariae of Posthodiplostomum centrarchi (Digenea: Diplostomidae) in largemouth black bass, Micropterus salmoides (Actinopterygii: Centrarchidae), transported from France to Ukraine for aquacultural purposes. The parasite was co-introduced with the fish host with a prevalence of 100% and an infection intensity range of 14-90 (mean 52.1±28.5). The metacercariae were morphologically and genetically identical to those recently described from largemouth black bass in Portugal. Fish translocation for aquacultural purposes is discussed as a source of disease transmission.
