The article describes occurrence and distribution of Eustrongylides trematodes in fish in the waters of the Dnipro-Buh estuary and the delta of Dnipro River in Mykolaiv and Kherson Region. Study was conducted in 2015–2016. This parasite was found in natural water reservoirs in Mykolaiv and Kherson region in following fish species: Sander lucioperca (Linnaeus, 1758), Perca fluviatilis (Linnaeus, 1758) and Esox lucius (Linnaeus, 1758). Ichtyopathological investigation of 346 fishes was conducted. Parasites were observed in abdominal cavity, muscle tissue, wall of gastro-intestinal tract, gonads and hepatopancreas. P. fluviatilis was the most affected species, prevalence of infection was 85.1 %. Less infected were S. lucioperca and E. lucius, with the prevalence of infection 58.1 % and 58.9 % respectively. Mean prevalence of infection of predatory fish in studied reservoirs was 70.5 %. The intensity of infection was the highest in perch (1–14 nematodes per fish). The lowest intensity of infection was found in pike-perch (1–9 nematodes per fish).

The article presents the results of the research concerning the morphological changes in the blood of the predatory fish species (perch, pike and zander) сaused by nematodical parasitic disease -eustrongylidosis. The research has been conducted in [2014][2015][2016][2017][2018]. It has been found that in the blood of perch with eustrongylidosis the hemoglobin and the red-blood-cell count decreased by 6.87 and 42.11 respectively, the white-blood-cell count increased by 8.95%; the basophils and pseudobasophils count -by 129.17%; the eosinophils and pseudoeosinophils count -by 131%; the number of band and segmented neutrophils increased by 27.92 and 37.5% respectively; the young neutrophils were not registered; the number of monocytes -by 16.34%; the lymphocyte count reduced by 3.27% in contrast with a fish that were not sick with the disease. The significant morphological changes in the blood of pikes with eustrongylidosis were also observed. Thus, the hemoglobin concentration, the number of red blood cells and lymphocytes decreased by 11.02, 26.32 and 3.16% respectively. The total leukocytes count increased by 22.02%; the basophils and pseudobasophils count -by 114%; the eosinophils and pseudoiesinophils count -by 95.83%; the number of band and segmented neutrophils increased by 1.71 and 46.72% respectively; a reduction of the young neutrophil granulocytes amount to 26% was noted; the number of monocytes of the blood increased by 25.83% in contrast with pikes that were not affected by the eustrongylidosis. A reduction of the red-bloodcell and lymphocytes amount, as well as hemoglobin concentration -to 30.05, 4.4 та 6.3% respectively was observed in hematological screening of the blood of zanders. The amount of leukocytes in the blood of infested fish increased by 10.6%; the basophils and pseudobasophils count -by 69.23%; the eosinophils and pseudoeosinophils count -by 116.67%; the number of band and segmented neutrophils increased by 15.58 and 23.27% respectively; the elevation of the number of young neutrophils to 5.75% was registered; the number of monocytes increased by 17.46% in contrast with zanders that were not infested. Морфологічні зміни крові хижих видів риб за еустронгілідозу С.Л. ГончаровНаціональний університет біоресурсів та природокористування України, м. Київ, Україна У статті наведено результати дослідження морфологічних змін у крові хижих видів риб: окуня, щуки та судака за нематодозного паразитарного захворювання -еустронгілідозу. Дослідження проведено у період 2014-2018 рр. Виявлено, що за еустронгілідозу в крові окуня вміст гемоглобіну та кількість еритроцитів зменшується на 6,87 та 42,11 відповідно, кількість лейкоцитів зростала на 8,95%; базофілів та псевдобазофілів на 129,17%; еозинофілів та псевдоеозинофілів на 131%; кількість паличко-та сегментоядерних нейтрофілів збільшувалась на 27,92 та 37,5% відповідно, юних нейтрофілів не реєстрували; моноцитів -на 16,34%; кількість лімфоцитів крові зменшувалась на 3,27% порівняно з рибами, що не були хворі на зазначене захворювання. У крові щук так...
