Bazeev ABSTRACT The expansion of ligulosis among fishes in different parts of the Kiev Reservoir was studied during 1997-2001. It is shown that mean numbers of fishes (Rutilus rutilus, Blicca bjoerkna, Abramis brama, Abramis ballerus, Leucaspius delineatus) invaded by Ligula plerocercoids were 2.5 times higher in the upper part of the reservoir than that in its lower part. It has been stated the existence of an age dynamics in the intensity of infestation of white bream (Blicca bjoerkna) with Ligula, while seasonal dynamics was not detected.
