Abstract Tolerance of adult zebrafish and efficacy of emamectin benzoate and ivermectin in eliminating Pseudocapillaria
tomentosa infection were evaluated. In the tolerance study, behavioral changes, fecundity, histopathology,
and mortality were evaluated for in-feed administration of emamectin (0.05, 0.10, and 0.25 mg/kg) and
ivermectin (0.05 and 0.10 mg/kg). All doses of emamectin were well tolerated. Ivermectin 0.05 mg/kg administration
resulted in mild behavioral changes and a transient decrease in fecundity. Ivermectin 0.10 mg/kg
administration resulted in severe behavioral changes and some mortality. In the efficacy study, emamectin (0.05
and 0.25 mg/kg) and ivermectin (0.05 mg/kg) were evaluated for their efficacy in eliminating P. tomentosa
infection. Emamectin reduced parasite burden in infected zebrafish, and ivermectin eliminated intestinal
nematode infections. Despite a small margin of safety, ivermectin 0.05 mg/kg was effective at eliminating
P. tomentosa infection in adult zebrafish. Higher doses or a longer course of treatment may be needed for
complete elimination of P. tomentosa infection using emamectin. In this study, we propose two possible
treatments for intestinal nematode infections in zebrafish.
