Tissue distribution and field evaluation of caprylic acid against natural infections of Sparicotyle chrysophrii in cage-reared gilthead sea bream Sparus aurata

It is concluded that a dietary dosing of 200 mg caprylic acid/kg for 60 d can significantly affect S. chrysophrii intensity in cage-reared gilthead sea bream when treatment is implemented at the first disease stages. It is thus recommended that the progress of the disease should be continuously monitored in the farmed population during the production cycle and administration of caprylic acid should be initiated prior to the development of the infection.
