Abstract

The purpose of the work is to determine the veterinary and sanitary well-being for helminth infections of fish in water bodies of economic importance in the Chelyabinsk region. To study the helminth fauna and determine the veterinary and sanitary well-being of the hydrobionts of lakes in the Chelyabinsk region, we studied the infection of parasitic worms of crucian fish (Carassius), peled (Coregonus peled), roach (Rutilus rutilus), perch (Perca fluviatilis) and rotan ( glenii) in Mayan, Kurakli-Mayan and Sugoyak lakes. As a result, invasive pathologies of diplostomiasis (Diplostomoses) and proteocephalosis (Proteocephalosis) were recorded. The greatest extent of invasion (EI) and intensity of invasion (II) were recorded for diplostomy in peled and roach - up to 40 and 60% and 3 ... 25 units, respectively. and 9 ... 23 units, as well as in juvenile perch - 40,0% and 16 ... 25 units, respectively. We detected proteocephalosis only in peled, while EI and II were relatively low, respectively, about 20% and 2 ... 4 units. Rotan was free from helminths. Thus, in general, the veterinary and sanitary state of fish in the studied reservoirs of the Chelyabinsk region for helminth infections can be considered satisfactory, given the fact that the registered diseases are not zooanthroponoses. However, a sufficiently high infection rate of fish with diplostomiasis certainly affects the potential fishery productivity of aquatic organisms.
