Purpose. Analysis of structural indicators of the population of Blicca bjoerkna L. in the Kremenchuk reservoir in the world increasing its importance in the composition of industrial catches and development of methodological approaches to its use to reduce the industrial load on the catch of major industrial species. Methodology. Primary materials were collected at the monitoring sites of the Institute of Fisheries of NAAS, performed in the surface area of the Kremenchuk reservoir during 2016–2021. Findings. The article establishes the general basic population indicators of the population of Blicca bjoerkna L. in the Kremenchuk reservoir. Indicators of natural, commercial and general mortality of the population are established. The originality: the findings of the work serve the sustainable use of aquatic bioresources of natural reservoirs as a basis of scientifically sound principles for sustainable fisheries. Practical Value: the population indicators conducted in the work can be used to calculate the limits of the commercial catch of silver bream in the Kremenchuk reservoir to ensure its sustainable use.
