Russian fishermen in the South Pacific Ocean are struggling to catch horse mackerel due to the El Niño phenomenon, which has warmed the waters and disrupted fish concentrations. Despite meeting the 2023 quota and receiving an additional quota from China, the 2024 season has started poorly with no significant fish schools found. However, scientists note that the influence of El Niño is weakening, which may improve fishing conditions for horse mackerel and mackerel later in the year.
