Abstract
Results of analyzing the spawning sockeye salmon age structure, length-weight composition and absolute fecundity are demonstrated for the Ozernaya River stock. In the course of maturation the sockeye salmon individuals can return into the Ozernaya River for spawning in the ages 3+, 4+, 5+, 6+ or 7+. A positive trend has been figured out for relative abundance of the 5+ and 6+ sockeye salmon individuals and generation abundances, a negative trend – for the 4+ individuals. Negative dynamics has described for the averaged length-weight indices and the mean absolute fecundity of sockeye salmon of the Ozernaya in the research period. Patterns of changes in biological indicators of the fi sh depending on density factors in the period1971–2020 have been identified.

Supporting agencies: Author is grateful to all current working, retired and gone colleagues from KamchatNIRO, who participated in collecting the Ozernaya River sockeye salmon stock biostatistical materials at the Ozernovsky Biological Station or fi shing enterprises in the Ozernovsky settlement, who carried out surveys of Pacifi c salmon throughout Kamchatka Peninsula from the air: Anatoly G. Ostroumov, Konstantin Yu. Nepomnyaschiy, Alexey V. Maslov, Sergey V. Shubkin, Anton M. Biryukov, Igor N. Kireev and Mark G. Feldman, who kindly shared data for this research about the returns of pink salmon to Kamchatka.
