This study evaluated the use of therapeutic baths containing essential oils of Lippia sidoides (pepper rosemary)and Mentha piperita (peppermint) on the hematological parameters of Nile tilapia parasitized by the monogeneansCichlidogyrus tilapiae, Cichlidogyrus thurstonae, Cichlidogyrus halli, and Scutogyrus longicornis. A total of320 juvenile fish were distributed into 16 tanks of capacity 100 L (20 fish per tank), divided into 4 treatmentsin quadruplicates: fish exposed to a bath of L. sidoides at 20 mg L−1; fish exposed to M. piperita at 40 mg L−1;fish exposed only to a water bath; and fish exposed to water + DMSO (dimethyl sulfoxide) bath. The fishwere subjected to 3 baths for 10 min, at intervals of 24 h between treatments. After the third bath, parasitologicaland hematological analyses were performed. The parasite prevalence in fish treated with essential oils was seento have decreased by 70%. The efficacy attained among fish treated with L. sidoides, in comparisonwith controlwater and water + DMSO, was 1.96% and 14.16%, respectively; and among fish treated with M. piperita, itwas33.33% and 41.63%, respectively. The total numbers of red blood cells (RBC) and thrombocytes were lower infish treated with L. sidoides. Glucose concentration and neutrophil count were significantly higher in fish treatedwith L. sidoides. Because of the efficacy and positive hematological results, we suggest that baths ofM. piperita at40 mg L−1 should be used as anthelmintic action.
