The integrated krill assessment model for Subarea 48.1 with future catches meeting alternative decision rules
Abstract: Model results and diagnostics for the integrated assessment model for krill in Subarea 48.1 are summarized. Alternative potential decision rules based on the distributions of krill spawning biomass during different reference periods, and potential catches associated with those rules, are

The ecosystem approach to managing fisheries: achieving conservation objectives for predators of fished species
Abstract: Managing fisheries to achieve ecosystem objectives is in its infancy. A general approach for maintaining ecological relationships and providing for the recovery of depleted populations in food webs supporting fisheries is proposed. This paper addresses the following general questions for

The feeding peculiarities of the Antarctic seals in the region of the archipelago of Argentina Islands
Abstract: The detailed analysis of a food of the Antarctic species of seals around Argentine islands archipelago, that was spent through out 11 Ukrainian Antarctic expedition (2006-2007), has shown that krill (Euphausia superba) is the main type of food for the major species of seals in region.

Changing status of three notothenioid fish at the South Shetland Islands (1983–2016) after impacts of the 1970–80s commercial fishery
Abstract: Owing to commercial fishing during the late 1970s/early 1980s, targeted notothenioid species had become depleted around the South Shetland Islands. Herein we report subsequent changes in the prevalence of three species, Notothenia rossii, Gobionotothen gibberifrons and N otothenia

How trophic dynamics of adult Antarctic krill Euphausia superba responses to the condition of no ice in the water during the winter: a case study at South Georgia?
Abstract: Understanding the variation in krill diet during winter is crucial to elucidate the overwintering of krill in the Southern Ocean. The information on trophic variation of krill under ice-free waters during the winter can also provide the insight for understanding the response of krill to

Marine ecosystem acoustics (MEA): quantifying processes in the sea at the spatio-temporal scales on which they occur
Abstract: Antarctic ecosystems are dynamic and characterized by physically forced variability caused e.g. by fronts, eddies and ice. This creates a challenging dynamics for scientific sampling and monitoring. Realistic understanding of what can and cannot be achieved with the available sampling
