Fish averaging 100.2 ± 17.7 g and kept at 25oC received a PZQ-dosing of 150 mg/kg fish for 3 days. Muscle plus skin of each of ten fish were collected on days 1, 2, 3, 4, and 6 days post-treatment. Depletion of PZQ from the edible gilthead sea bream tissues was rapid, as its concentrations declined to 0.04 μg/g as early as 24 h post-treatment, while was undetectable at 72 h. This information confirms the fact that PZQ is depleted fast from farmed animals including fish such as the gilthead sea bream and its levels in edible tissues failed below the detection limit in approximately 75 dd. |

Differences in final weight, feed conversion ratio, specific growth rate and feed efficiency were not statistically significant between the experimental groups, suggesting no evident effect with respect to fish growth during the study period.
