    Abstract

    Captive white-spotted eagle rays (Aetobatus narinari) were infested with Clemacotyle australis (Monogenea: Monocotylidae) on the skin and with a species of the Hexabothriinae on the gills. Different behavioural changes have been described caused by these infections. Oral treatment with 10-40 mg praziquantel per kg bodyweight had no effect. Bath treatment with 20 mg praziquantel per litre for 45-90 minutes showed good results against both parasite species. The presence of cleaner wrasse (Labroides dimidiates) in the display tank decreased the infections of the rays.
