    Abstract

    This paper discussed the krill flux indices through the Antarctic Peninsula based on the results complex survey provided by RV Atlantida in 2020 including   repeated complex acoustic surveys in the Brnsfield Strait and repeated transect across Elephant Island.  Geostrophical water masses circulations, spatial distribution of krill density, water flow intensity (m3/s) and krill biomass (g/m3) transported by water flow , variability of krill length compositions are shown.  There was no krill fishing in the Bransfil Strait during the research surveys as well as between these surveys. The latter provided favorable conditions for understanding the effect of krill flux on krill  distribution and biomass in context of krill fishery management.
