The very common parasites in all three sites Diplostomum spp. with species were Tylodelphys clavata (metacercariae; Platyhelminthes: Diplostomidae), Diplozoon paradoxum (Platyhelminthes: Diplozoidae), Caryophyllaeus laticeps (Platyhelminthes: Caryophyllaeidae), Asymphylodora imitans (Platyhelminthes: Lissorchiidae), as well as Raphidascaris acus (Nematoda: Raphidascarididae).
