Why does it necessary to consider krill flux for developing the feedback management strategy for krill fishery in the Area 48?

The authors discussed the necessity to investigate krill flux for estimating the local harvest rates-indicators that could be used to reveal the potential risk of the fishery development. Estimates of krill flux factors in Subarea 48.3 based on the Soviet/Russian scientific observations from 1962 to 2002 are shown as an example.
