Essay

The thesis is devoted to establishing the morphological variability and structure of roach and perch populations in different types of river systems. For the first time, the growth peculiarities of roach and perch ecomorphological groups and the mechanism of their juveniles’ distribution into separate eco-morphological groups were determined. It has been shown that the population structure of both species in rivers is characterized by heterogeneity and consists of two subpopulation eco-morphological groups: a stunted and a fast-growing roach and a stunted and a fast-growing perch.
