The analysis of reference and analytical information on the results of work on the artificial cultivation of juvenile roach in the NVH in mono and polyculture; the results of observations from the early 70s to the 2000s on the quantitative and qualitative composition of juveniles of semi-migratory fish species obtained from the self-entry of producers in the NVH during the cultivation of profile species (bream, carp), the influence of the dependence of the NVH, watered by gravity, on the hydrological regime of the Volga River during flood waters and reclamation works. It is determined that in order to increase the survival rate of juvenile roach during artificial reproduction in the NVH, research will be required, including experimental work to determine fish-breeding and biological indicators, the development of methods and standards for this species, taking into account the current state of the population.
