Ichthyological trawling reveals changes in fish distribution and biomass in Barents and Kara Seas, suggesting shifts in marine ecosystem dynamics.
During marine expedition at RV “Dalniye Zelentsy” in the summer of 2024, an assessment of the current state of the fishing communities of the eastern part of the Barents and western parts of the Kara Seas was carried out. In the north-east of the Kara Sea, a unique ichthyological survey was carried out using a coordinate grid repeating the research of 1930-1935. Ichthyological trawling has also been carried out in the Barents and the Kara Sea along of the Novaya Zemlya archipelago. As a result of the research, new data have been obtained on the species composition, abundance, biomass, distribution and condition of the ichthyofauna of these areas.
