Lysac N. Treatment and prophylactic measures at invasionaldiseases of young rainbow troit under the conditions of western region of Ukraine

Thesis is dedicated to the analysis of treatment and prophylactic measures at invasional diseases of young rainbow troit in the condition of western region of Ukraine, by the intensive technology of fish growing in water pools for young trout taking into account the fish economies and seasons. During the work in trout economies it was determined the extensity and intensity of parasite fauna of young rainbow trout: the simpliest - Costia necatrix, Ichtyophtirius multifilis, Apiosoma piscicolum, Hexamita truttae, Trichodina nigra, monogenetic sucklings - Diplostomum spathaceum and trematodes - Gyrodactylus salaries. For the first time in the economies of western region of Ukraine in young trouts at intensive technology of growing was found out the causative agent of hexamitose (Hexamita truttae). It was also determined and theoretically proved the similarity of parasite fauna of young trouts in highland end lowland economies. The dynamics of mixed invasion of simpliest (ichthyophthiriosis - hexamitose) were discovered, in young trouts it was determined the periods of the highest intensity, which occur during spring and summer months and the dependence of its arising. The expediency of using the sterediale W5 and avimetronide, brometronide novyj as prophylactical - treatment measures at ichthyophthiriosis and hexamitosis in young trouts was scientifically grounded.
