1. Detection of growth zones in the eyestalk of the Antarctic krill Euphausia superba (Dana, 1852) (Euphausiacea)

   Abstract:  No reliable measures of age currently exist in the Antarctic krill, Euphausia superba (Dana, 1852). The eyestalks from 51 individuals were dissected, cut in longitudinal sections and studied for identifying growth zones. The krill was collected at the South Orkney Islands during January

3. Quantifying the escape mortality of trawl caught Antarctic krill (Euphausia superba)

   Abstract:  Antarctic krill (Euphausia superba) is an abundant fishery resource, the harvest levels of which are expected to increase. However, many of the length classes of krill can escape through commonly used commercial trawl mesh sizes. A vital component of the overall management of a fishery

6. Proposal of extension of research block 48.6_2 to complete planned research and examine the habitat model and the stock structure

   Abstract:  Here we propose the northeastward of research block of 48.6_2 along ridges to promote sufficient utilization of the catch limit, which enable us to complete planned research, evaluate the habitat model and elucidate stock structure. The distribution of densities (catch per haul in 20
