Research Article: Prevalence and intensity of Paradiplozoon homoion (Monogenea: Diplozoidae) from Manyas spirlin, Alburnoides manyasensis, an endemic fish of Turkey: new host and geographical record

In this study, the occurrence of a parasitic helminth infecting a Turkish endemic fish, Manyas spirlin, Alburnoides manyasensis from the Nilüfer stream, Bursa, was studied from winter ۲۰۱۷ to autumn ۲۰۱۸. A total of ۴۶ A. manyasensis were examined for the presence of the helminth. The helminth was identified as Paradiplozoon homoion (Monogenea: Diplozoidae) and occurred on the gills of host fish. A total of ۱۱۵ specimens of P. homoion infected ۳۲ of ۴۶ fish examined, with prevalence and mean intensity of infection of ۶۹.۵۷% (۴۱.۶۷% in Summer to ۹۰.۰۰% in Winter) and ۳.۵۹ (۱.۰۰ in Summer to ۶.۲۲ in Winter) respectively. Additionally, prevalence and mean intensity of infection was calculated per seasons, host size and sex. The highest values for prevalence and intensity of infection were found in winter for P. homoion. To our knowledge, this is the first ichthyoparasitological study for A. manyasensis in Turkey. This is also the first record of P. homoion from this host fish and locality.
