Evaluation of Praziquantel Efficacy against <i>Zeuxapta seriolae</i> Infections in Greater Amberjack, <i>Seriola dumerili</i>
The aim of this study was to evaluate the efficacy of dietary praziquantel (PZQ), a promising fish anthelminthic, against <i>Zeuxapta seriolae</i>, a lethal ectoparasite of greater amberjack (<i>Seriola dumerili</i> Risso) farmed in the Mediterranean and elsewhere. The trial...

| description | The aim of this study was to evaluate the efficacy of dietary praziquantel (PZQ), a promising fish anthelminthic, against <i>Zeuxapta seriolae</i>, a lethal ectoparasite of greater amberjack (<i>Seriola dumerili</i> Risso) farmed in the Mediterranean and elsewhere. The trial was carried out in small cages (3 m<sup>3</sup>) in situ, harbouring fish (125 ± 14 g) naturally infected with <i>Z. seriolae</i>, at 25 ± 1 °C water temperature. Praziquantel-medicated diet (150 mg PZQ/kg fish) was delivered for three days against a control group. Measurement of both adults and oncomiracidia of <i>Z. seriolae</i> in sampled gill arches revealed significant differences between the tested groups (PZQ: 19.3 ± 9.8 vs. Control: 3.8 ± 6.3). Considering an estimated efficacy of 80.4% in the medicated fish, the present study indicates that oral PZQ treatments can confront <i>Z. seriolae</i> infections considerably in farmed greater amberjack and, perhaps, replace the commonly used hydrogen peroxidase baths. |
