Abstract
Results of the salmon fishing campaigns in the Kamchatka Region in 2024 and 2025 are reviewed. Detailed data of fishery statistics concerned pacific salmon, estimations of their runs abundance and spawning stocks are presented for all salmon species and compared between these years and with long-term indices of the regional stocks dynamics (annual catch, spawning escapement and run abundance) for 2001–2025. Accuracy of the run and catch forecasts is analyzed for the major stock units in 2024–2025 and possible reasons for discrepancies of the forecasted expectations with real situation are discussed.
