Fig. 5: Schematic of seasonal spatial and temporal distribution of Antarctic krill life-stages in relation to fishing activity.

From: Successful ecosystem-based management of Antarctic krill should address uncertainties in krill recruitment, behaviour and ecological adaptation

Fig. 5

The y-axis (left) shows the distance of life stages from land across seasons26, whereas the x-axis (right) shows the relative abundance of post-larval krill in relation to fishery captured krill. Superimposed onto background levels of all krill stages across time and space are bulk movements of the adult population from inshore-shelf regions during winter to shelf-beak and off-shelf regions during summer. The dashed red line indicates the relative abundances of post-larval krill within the present-day fishing region. The blue shaded region indicates captured krill during the present-day krill fishing season and is based on 2017 catch data from CCAMLR (note that fishing gear optimally retains immature and adult krill)103.
