Conclusion: Exploring the presence of trematodes in fish of the river Spreča we found that 39.45% of the examined fish were invaded by parasites in the survey period. All the fish in which parasites were found belonged to the family Cyprinidae. The largest extensity of infestation was found in Chub 63.63% and Nase 54.54%. In Rudd, Bream, Carp and Sunbleak the extensities of infestation were lower whereas in Prussian carp it was only 25%. The highest intensity of infestation was found in Rudd. The parasitological examinations of fish in Spreča river discovered the presence of 4 species of trematodes, so that two species of the order Monogenea belonged to the families Dactylogyridae and Gyrodactylidae, and two species of the order Digenea were classified in the family Diplostomidae. Individually, we have found that the highest extensity of infestation was with Diplostomum spathaceum (14, 79%), slightly lower extensity was with Dactylogyrus sp. (12.86%) and 9.86% with Posthodiplostomum cuticula. The lowest invasion level in fish was with Gyrodactylus sp. as it was found to be only 1.91%. Invasion degree of the fish in Spreča river by trematodes shows proper seasonal dynamics.
