Abstract. The leukocyte profile (leukoformula) was determined by smears from whole blood painted by Pappenheim in four fish species – carp (Carassius) (n = 10), peled (Coregonus peled) (n = 10), roach (Rutilus rutilus) (n = 5) and perch (Perca fluviatilis) (n = 5) in lakes of the Chelyabinsk region of Mayan, Kurakli-Mayan and Sugoyak fishery. Individual values of leukogram indices were transformed using the arcsine phi-transform, the average and 95 % confidence interval (CI) were calculated as for quantitative traits, and the results were re-transformed into the original scale using the inverse transform. Calculations and graphical constructions are made in PAST (version 3.20) and KyPlot (version 2.15) packages. The completed veterinary-sanitary examination of the fish groups examined showed that the samples studied were in compliance with legal documents. The fish from all the examined lakes according to the results of a clinical examination on the history of life (Anamnesis vitae) corresponded to the state of a healthy organism. In general, the results obtained corresponded to the regulatory data and were due to the biological characteristics of the fish, the type of animal nutrition. In the leukoformula of all studied groups of fish, the largest number was represented by lymphocytes – more than 80 % and neutrophils from 15–20 % in the blood of the perch from lake Sugayak. More than 30 % of the neutrophils content in the leukocyte profile had crucians and peled from the lakes Mayan and Kurakli-Mayan. However, as a percentage, lymphocytes prevailed in the blood of a perch from lake Sugoyak in a comparatively maximal manner – up to 80 %. The results obtained are exploratory in nature and are the basis for further work on the search for marker indicators of the ecological and physiological state of biological resources in reservoirs of economic importance.
Keywords: fishery reservoirs, leukocyte’s profile, lymphocytes, neutrophils, fish.
