Abstract
The article assessed the species composition, abundance and size-weight indicators of juveniles in the coastal zone of the Volzhsko-Sviyazhsky region of the Kuibyshev Reservoir in september 2021-2023. Among the juveniles, the young of the current year fishes of 24 species were identified. The quantitative indicators of the young of the current year fishes differed significantly in different years, which is due to the conditions of reproduction. The conditions for the growth of juveniles were assessed based on size and weight indicators. Since the first decade of the current century, the species diversity of young-of-the-year fish has increased due to southern invaders and local species that spawn in late spring and early summer. This, together with the higher size and weight indicators of juvenile fish of the current year, allows us to assume the influence of the climatic factor on the parameters of juvenile fish in the coastal zone in the autumn.
