Plerocercoids of Triaenophorus nodulosus are common liver infections of European perch (Perca fluviatilis).

The prevalences of A. lucii and C. lacustris were significantly reduced in fish infected by T. nodulosus, although the mean intensity of infections remained unaffected for any helminth species, while the mean abundance of C. lacustris was significantly reduced in plerocercoid-affected perch.
