The composition, abundance and reproductive characteristics of the demersal fish fauna in the Elephant Island–South Shetland Islands region and at the tip of the Antarctic Peninsula (CCAMLR Subarea 48.1) in March–early April 2012
Abstract: A bottom trawl survey for demersal finfish was undertaken by Germany aboard R/V ‘ Polarstern ’ around Elephant Island, the South Shetland Islands and at the tip of the Antarctic Peninsula from 17 March to 5 April 2012. In this paper we provide information on species composition, biomass,

Dissostichus mawsoni distribution and biology
Abstract: The present work includes results of seven-year own author’s research and presents generalised knowledge about distribution and biology of the antarctic toothfish in different sectors of the Antarctica. Author(s): A.F. Petrov (Russia) Title: Dissostichus mawsoni distribution and

Does large-scale ocean circulation structure life history connectivity in Antarctic toothfish (Dissostichus mawsoni)?
Abstract: A multi-disciplinary approach incorporating otolith chemistry, age data and numerical Lagrangian particle simulations indicated a single, self-recruiting population of Antarctic toothfish (Dissostichus mawsoni) in the Southeast Pacific Basin (SPB) and Ross Sea, with a life history

Trophic interactions and population trends of killer whales (Orcinus orca) in the southern Ross Sea
Abstract: Foraging events and related trends in numbers of Type-B and-C killer whales (Orcinus orca) are reported for the vicinity of Ross Island, Ross Sea, Antarctica, between 2002 and 2010. Updating an earlier report, the frequency of sightings and the number of individuals per sighting of Ross

Decadal trends in abundance, size and condition of Antarctic toothfish in McMurdo Sound, Antarctica, 1972–2011
Abstract: We report the analyses of a dataset spanning 39 years of near-annual fishing for Dissostichus mawsoni in McMurdo Sound, Antarctica, 1972–2011. Data on total length, condition and catch per unit effort (CPUE) were derived from the > 5500 fish caught, the large majority of which were

Influence of the quality and quantity of data from a multi-year tagging program on bias and precision of biomass estimates from an integrated stock assessment – update
Abstract: By way of simulation, this study investigated how the bias and precision of biomass estimates from an integrated tag-based assessment are influenced by various aspects of a multi-year tagging program, in particular the effects of the size (tag size-overlap) and numbers of tagged fish,

Has Notothenia rossii around Elephant Island and the lower South Shetland Islands (Subarea 48.1) recovered from exploitation some 30 years ago?
Abstract: The marbled notothenia (Notothenia rossii) was the first species targeted by commercial fishing in the Southern Ocean. The species has been heavily fished around South Georgia and Iles Kerguelen in the first half of the 1970’s and at Elephant Island in 1979/80. The closure of the fishery

The recent decline in recruitment of Gobionotothen gibberifrons in the South Shetland Islands (CCAMLR Subarea 48.1)
Abstract: Commercial exploitation of fish stocks around Elephant Island and the lower South Shetland Islands ceased after the 1989/90 season. One of the larger and most abundant species in the area, Gobionotothen gibberifons, was only lightly exploited compared to more northerly fishing grounds

Characteristics of population-genetic structure of Antarctic toothfish (Dissostichus mawsoni) from near-continental seas of Pacific, Indian and Atlantic sectors of the Antarctica
Abstract: Population-genetic structure of Antarctic toothfish (Dissostichus mawsoni) was investigated not once during the last decade and before, but in this work we present our data on DNA-analysis of recent samplings of toothfish from CCAMLR Subareas – 88.1, 58.4.1, 58.4.2 and 48.6. Our findings
