    Résumé

    The dynamic of krill fishery in the Subarea 48.1 and its relation to the environment variability was analyzed.  It was revealed  that the dynamic of ААО indices (Antarctic Oscillation Index) used as an indicator of the inter-annual and long-period fluctuations of hydrometeorological conditions at high latitudes of the Southern Hemisphere was traced through the climatic changes of the environmental parameters (air temperature, atmospheric transport intensity, ice situation) in the Subarea 48. 1. The observed changes in the interannual and seasonal dynamics of the krill fishery in Subarea 48.1 are consistent with climatic changes of these environmental parameters.
