On the examining of krill flux

In connection with future calculation of volume of krill immigration/emigration (flux) in the choosen polygones, the proves of active long-distance migrations of krill are considered. These proves are not undoubted. The most difficult problem, which nevertheless should determine the results of calculations, is the valuation of krill retention time. To make it more correct and natural it is necessary to take into account the biological characteristics of krill, especially for the regions outside the shelf and slope areas of investigating regions.
