“…In autumn and winter, a deep mode of DVM was apparent from significant diel differences in Antarctic krill density of the epipelagic layer (Table 5). Our results agree generally with commonly accepted paradigms of seasonal DVM patterns in Antarctic krill (Siegel, 2005(Siegel, , 2012Taki et al, 2005). The data shown here extend the accepted model of hibernal DVM by highlighting that nocturnal upward migration encompasses the surface layer even in winter (Flores et al, 2012).…”

“…Especially during summer, the median proportional density of Antarctic krill in the surface layer reached over 200% of corresponding epipelagic densities. This extra-ordinarily high proportional surface layer density was unlikely to be confounded by the different diel sampling regime of the surface versus the epipelagic layer, because during summertime there is no evidence of DVM in Antarctic krill at high latitudes (Table 5; Siegel, 2005Siegel, , 2012. Even a tentative correction of the almost two-fold higher night-time than daytime median densities in the epipelagic layer would result in summer surface layer densities still about 2 orders of magnitude higher than expected from random depth distribution ( Fig.…”

“…In contrast to the present hypothesis that sea ice acts primarily as a feeding ground for overwintering larvae, we suggest that the pack-ice zone is actually a food-poor habitat that allows larvae to only maintain a positive metabolic balance with slow growth rates 14,15 . During winter, the larvae feed on food particles released from the ice or associated with it 14 but not directly on the algae communities growing on or in the ice as has previously been suggested [5][6][7] .…”

“…Therefore, winter, when primary production is minimal, is assumed to be a critical bottleneck for larval krill development and hence recruitment to the adult population 3,4 . Present hypotheses suggest that high algal biomass in winter sea ice enhances larval krill winter-feeding conditions and growth [5][6][7][8] . This implies that larvae have access to this high algal biomass within the sea ice.…”

“…DVM was observed in Antarctic krill, Euphausia superba (Godlewska, 1996;Siegel, 2005;Taki et al, 2005), Thysanoessa macrura (Nordhausen, 1994) and Euphausia crystallorophias (Everson, 1987). Taki et al (2005) used Japanese fishery data from the Scotia Sea and analysed the average trawling depth of the Krill catches.…”
