After examining the parasitology of the worms, a suitable treatment protocol was made to treat the fish. In this case, the fish were divided into ۲ groups of ۶۰ in three repetitions. The first group was treated with levamisole at the rate of ۱۰ mg/liter as a long-term bath (۲۴ hours), which was repeated on the ۷th and ۱۴th days of the experiment. And the second group was fed orally to fish with the same drug at the rate of ۱% of the weight of food consumed for ۷ days.
