During recent years the scientists from different countries carried out comprehensive studies on monogenoues fish and developed methods for the treatment and prevention of these diseases. However, antiparasitic drugs have a negative impact not only on the parasites but they also cause irritating effect on the fish. According to it, the purpose of our research was to study the effect of antiparasitic drug “Granulatebrovermectin™” and immunomodulator “Avesstim™” on hematological indices of the grass carps of age one year affected by various ectoparasites — Dactylogyrus lamellatus and Gyrodactylus ctenopharyngodonis.
The researches were conducted at “Galician fish farm” (Rohatyn district, Ivano-Frankivsk region) and at “Dobrotvir” (Kamyanka-Bug district, Lviv region). The treatment of fish was performed by feeding with food “Granulatebrovermectin™” in dosage 60 mg per kg of body weight during two days and consistently with drug “Granulatebrovermectin™” (60 mg/kg body weight) and immunomodulator “Avesstim™” (1 mg/kg body weight).
It was found out that the drug “Granulatebrovermectin™” and immunomodulator “Avesstim™” promotes activation of hematological indices in the grass carps of age one year affected by Dactylogyrus and Gyrodactylus, as it is indicated by increase of erythrocyte amount, hemoglobin and hematocrit in their blood and decrease of the number of white blood cells. The combined use of these drugs contributed to better performance in the aforementioned normalization of infested fish.
