چکیده انگلیسی
The nematode Hysterothylacium sp. (Nematoda, Anisakidae) may cause significant economic losses in fish production. In order to control the nematode larvae in juvenile pirarucu (52â¯Â±â¯3.2â¯g), the efficacy of essential oil (EO) of Piper aduncum when added to feed was evaluated. Chemical analysis of the EO composition had been performed previously, showing that 92% of the substance was dillapiole. After the palatability test, the efficacy of the EO was evaluated (0, 32, 48, 56, and 64â¯mL/kg) at 7 and 15â¯days, based on the blood parameters and the parasite load of the fish. The results showed significant differences for hematocrit and corpuscular constants at 7â¯days and for total proteins at 15â¯days between the treatment groups and the control group (without EO). The parasitic indices showed a prevalence of 100% for stage L3 larva of the nematode Hysterothylacium sp. At 7 and 15â¯days, the values of average intensity, average abundance, and intensity of parasites decreased with increasing EO concentration, and at 15â¯days, these were significantly lower between the treatment group and the control group, with an efficacy of 76.21% for 64â¯mL/kg. Thus, the EO of P. aduncum demonstrates anthelmintic potential in the control of nematode larvae in pirarucu without affecting fish homeostasis.
