Abstract Excerpt:
The West Kamchatka (WK) pink salmon stock is one of the largest salmon stocks in the Russian Far East. During the last 115 years this stock, along with considerable variations in catches, is characterized by a clear dominance of either odd-year or even-year generations over periods of 3–4 decades. Thus, odd-year returning pink salmon provided the high catches from the early 1940s to 1983, while the returns in even-numbered years were abundant in 1914–1940 and 1986–2020 (Fig. 1). In 2021, the new period with predominance of odd-year generations of WK pink salmon has begun.
