Russia: Low salmon catch in the Pacific Ocean in 2024 caused by global warming

Published 2024년 11월 28일

Tridge summary

In 2024, climate warming led to significant impacts on Pacific salmon populations, resulting in a failure of the salmon run and a drastic reduction in catches. The warming of feeding waters and changes in the hydrological regime of spawning rivers have reduced the survival rate of salmon generations, leading to declines in both Chukotka Autonomous Okrug's salmon stocks and in Arctic fishing areas of Alaska. Russia's salmon catch is projected to be half of the previous year, and the decline is mirrored in the Far East and Alaska, with forecast errors for both Russia and the USA being virtually identical at 27% and 26% respectively.

Climate warming in 2024 had a major impact on the failure of the salmon run due to the warming of the feeding waters of Pacific salmon and changes in the hydrological regime of spawning rivers. This was stated by the director of the Research Institute of Fisheries and Oceanography (VNIRO) Kirill Kolonchin at a meeting of the Far Eastern Basin Scientific and Industrial Council in Vladivostok. As the head of the Federal Agency for Fisheries Ilya Shestakov reported earlier, the catch of salmon species in Russia by the end of this year will amount to about 250-260 thousand tons - two times less than in 2023 and below the forecast for 2024. "We are currently living in an era of global warming. Average monthly and average annual temperatures regularly reach new record highs. Thus, 2024 is expected to be the warmest year in the entire period of meteorological observations. The previous year was 2023, and before that - 2016. With the rise in global temperatures, warming in the Arctic, to ...
