Abstract
The density of some species and total density of fishes have been estimated in river channel parts of the Ivankovo Reservoir in 2012–2015. The significant differences in the total abundance of fishes in 2012–2013 and 2014–2015 have been revealed. The increase in the number of tyulka (Clupeonella cultriventris (Nordmann, 1840)) in the Black and Azov seas in 2014–2015 was determined by their periodic fluctuations typical for any species with a short life cycle. Changes in the abundance of bream and silver bream in the reservoir pelagial relate to their vertical redistribution under the effect of environment factors.
