“…At the same time, it should be emphasized that this year in terms of water level regime did not belong to the most favorable for breeding of the first type according to the typification of V.A. Kuznetsov [6,12]. According to this classification, three main types of water level regime are distinguished.…”

“…It is necessary to take into account the behavioral characteristics of some fish species. Such species of fish as bream, bream, pikeperch, volga pikeperch in the autumn after feeding from the coastal area migrate to the depth, while perch, roach and pike are characterized by living in the first year of life near the coast [6]. The young-of-the-year fish belonged to 6 families, two of which, Gobies and Pipefishes, included only alien species.…”

“…Commercial stock of aquatic biological resources of this reservoir in 2000-2020 ranged from 29.2 to 37.2 thousand tons, and the catch -from 2.8 to 4.2 thousand tons [4]. In the reservoir the reproduction efficiency for many fish species is determined by the level and temperature regimes during the spawning season [5,6]. At the same time, it was noted that the importance of different sites of the reservoir for reproduction is not the same and may change over time [7,8].…”

To estimate the current significance of the area for fish breeding, the species composition and abundance of young-of-the-year of the coastal zone of the Volga-Sviyazhsky area of the Volga stretch of the Kuibyshev reservoir for 2021, 2022 were considered. The work to assess the species composition and abundance of the young fish was carried out at 7 coastal stations, at depths less than 2 meters. The number of young-of-the-year was calculated per unit of effort of the fingerling seine. Species diversity was assessed using the Shannon-Weaver index. Young of 23 fish species were identified, which confirms the reproduction of these species in the study area. Observational data are compared with earlier materials from 1993-2020. A trend towards an increase in the relative abundance and the species diversity of the young of fish, mainly due to low-value species, was noted. At the same time, in 2022, a relatively high abundance of the young, the main commercial species of the reservoir, the bream, was revealed.
