Persistence Assessment of Febantel and its Effects on Blood Profile in Juvenile Japanese Amberjack Seriola quinqueradiata

Persistence of Febantel (FBT) and its metabolites (FBZ) were assessed in Seriola quinqueradiata after 5 days gavage administration of 20 mg/kg body weight. ​FBT was not detected in any organs at 1 day post administration (dpa), but traces of FBZ were detected in the liver and kidney at 7 dpa. ​Neither compound was detected at 14 dpa. ​While S. quinqueradiata received 20 mg/kg of FBT had higher bilirubin and lower triglyceride values in the blood at 1 dpa, and lower plasma creatinine level at 7 dpa, these were not likely associated with severe damages of organs and physiological functions.
