Field trials were conducted to assess the efficacy of oral febantel (FBT) treatment at the dose of 10 mg/kg for 5 days against Heteraxine heterocerca and Zeuxapta japonica in Seriola fish. ​Numbers of gill flukes were checked 1 day before and 3 days after the treatment. ​In comparison to the control groups, fish given FBT-coated feed showed deworming efficacies of 99.9% to 100%. ​No mortality and no signs of drug toxicity were observed. ​These results indicate that in-feed administration of FBT is an effective and practical treatment for gill fluke infections in Seriola aquaculture.
