This note reports the anthelminthic efficacy of four compounds (praziquantel, niclosamide, netobimin and mebendazole) for the treatment of turbot infected naturally with the platyhelminth Bothriocephalus scorpii. Praziquantel and niclosamide were 100% effective when doses of 5 mg/kg and 40 mg/kg respectively were administered for 3 consecutive days.
