Data on forecasted catch, catch and effective catch utilization are presented for Pacific salmon and char. Also, analysis of fishing activities and their characteristics in 2021 is carried out. Quantitative estimates of spawners abundance, migration timing in rivers and catch dynamics are provided. Factors that drive expected and observed runs are considered. Efficiency of complex measures to support natural Pacific salmon reproduction is estimated. Preliminary forecast of Pacific salmon and char stocks for Khabarovsk Territory in 2021 should be acknowledged as generally satisfactory (reliability — 65.6 %). Several quota underutilization cases were linked to seasonal fishing restrictions and fish migrations peculiarities. Positive dynamics of fish at spawning grounds and incubation volumes at salmon hatcheries is elucidated. This supports prolongation of restrictions implemented in recent years.
